"We are all in the gutter, but some of us are looking at the stars." Oscar Wilde wrote that line in 1892, and it has been quoted so often that it has lost some of its edge — but for the story of British space technology in the 21st century, the sentiment is uncomfortably precise. Britain's space sector is a study in paradox: world-class engineering undermined by chronic underfunding, visionary concepts that die in the valley between prototype and product, and a commercial ecosystem so quietly competent that even most Britons do not know it exists.
🇬🇧 In Part 1 of this deep dive, we traced the arc from Black Arrow's triumphant-and-simultaneously-cancelled satellite launch in 1971, through four decades of institutional drift, to the creation of UKSA in 2010, Tim Peake's Principia mission, the £18.6 billion space sector of today, the Scottish space coast with its emerging spaceports, and the strategic gamble on OneWeb. We left off with the collapse of Orbex in February 2026 and the question of whether Britain's return to space was a sustainable trajectory or another false start.
Part 2 answers that question — or at least examines the evidence. The answer, as is often the case with British things, is complicated. It involves an engine that could have changed everything but ran out of money, a satellite company that proved small spacecraft could change the world decades before anyone else believed it, a rocket firm with Ukrainian roots and Scottish ambitions, an insurance market that has quietly become the financial backbone of the global space industry, a military satellite program that is finally being built entirely on British soil, and a city that manufactures more small satellites than anywhere in Europe. The story of British space is not a story of rockets and flags. It is a story of institutions, ingenuity, and the particular British talent for doing extraordinary things while pretending they are perfectly ordinary.
Reaction Engines and SABRE: The Dream That Almost Was
Of all the stories in British aerospace, none captures the national tendency toward brilliant conception followed by institutional failure quite like Reaction Engines Limited and its SABRE engine.
The company was founded in 1989 by three engineers — Alan Bond, John Scott-Scott, and Richard Varvill — who had worked together on HOTOL, a British government-funded horizontal-takeoff spaceplane concept that had been cancelled the previous year when its propulsion design hit fundamental aerodynamic problems. Rather than accept defeat, the three men started their own company in Oxfordshire with the conviction that the underlying idea — an engine that could breathe air at low altitudes like a jet and then switch to onboard liquid oxygen as a pure rocket at high altitudes — was not merely sound but transformative.
They called the engine SABRE: Synergetic Air-Breathing Rocket Engine. The vehicle it was designed to power was called Skylon — named after the slender, futuristic structure that had towered over the 1951 Festival of Britain, a fitting choice for a concept that was perpetually associated with a better tomorrow that never quite arrived.
The Engineering Breakthrough
The fundamental challenge of an air-breathing rocket engine is thermal. At Mach 5 — five times the speed of sound — air entering the engine intake has been compressed and heated to over 1,000 degrees Celsius. No conventional compressor can survive those temperatures. Every previous attempt at a combined-cycle engine had foundered on this problem.
Reaction Engines' solution was the precooler: a heat exchanger of extraordinary sophistication, containing thousands of thin tubes — each thinner than a human hair — through which supercooled helium flowed. Incoming air at 1,000°C was chilled to minus 150°C in less than one-twentieth of a second. The cooled air could then be compressed by conventional turbomachinery and fed into the engine's combustion chambers, where it burned hydrogen fuel. Above approximately Mach 5.5 and 26 kilometers altitude, the engine would close its air intake, switch to onboard liquid oxygen, and function as a conventional rocket engine for the final push to orbit.
The theoretical performance was staggering. A Skylon spaceplane powered by SABRE engines could, in principle, take off from a conventional runway, accelerate to Mach 5+ in the atmosphere while breathing ambient air (and therefore not carrying the enormous mass of oxidizer that makes conventional rockets so heavy), transition to rocket mode for orbital insertion, deliver 15 tonnes of payload to low Earth orbit, re-enter the atmosphere, and land back on the same runway — all as a single stage, fully reusable vehicle. No staging, no expendable hardware, no ocean recovery. The holy grail of space access.
Three Decades of Progress
For most of its 35-year existence, Reaction Engines operated on minimal funding, sustained by the conviction of its founders and a small team of engineers. The turning point came in 2010, when an independent review panel commissioned by the European Space Agency validated the SABRE thermodynamic cycle, concluding that "no impediments or critical items have been identified for the overall engine cycle." ESA subsequently provided funding for further development work.
The investment cascade followed. In 2015, BAE Systems acquired a 20 percent stake in Reaction Engines for £20.6 million. In 2016, the UK Space Agency and ESA committed £60 million for engine development. In 2018, Boeing HorizonX Ventures and Rolls-Royce invested as part of a £26.5 million round. By 2023, total funding had exceeded £150 million, with a £40 million round led by the UAE's Strategic Development Fund.
The engineering milestones were real and impressive. In April 2019, Reaction Engines demonstrated that its precooler could handle supersonic inlet conditions. In October 2019, it validated the precooler at simulated Mach 5 — hypersonic — conditions. In 2024, the company achieved what it described as a "ground-breaking" milestone: the successful integration of the precooler with a modified Rolls-Royce jet engine, achieving sustained operating conditions equivalent to Mach 3.5 during ground trials.
The Collapse
And then, on October 31, 2024, Reaction Engines entered administration.
The proximate cause was financial. The company needed approximately £150 million in additional funding to continue development toward a flight-ready engine. Its existing shareholders — BAE Systems, Boeing, and Rolls-Royce — declined to provide a bailout. Attempts to raise capital from new investors failed. PricewaterhouseCoopers was appointed as administrator. Of the company's 208 employees, 173 were made redundant immediately. The remaining staff were retained briefly to complete existing orders and wind down operations.
The administrators put the total deficiency at over £160 million, including shareholdings that were now worthless. By mid-2025, PwC had identified a preferred bidder for the company's intellectual property — primarily the precooler technology and associated patents — but as of early 2026, the sale had not been completed, and the identity of the bidder remained confidential.
The deeper cause of the collapse was the gap between technological validation and commercial viability. Reaction Engines had proven, conclusively, that its precooler worked. What it had not done — what it had not been able to do, given the funding available — was build a complete, integrated SABRE engine and demonstrate it in flight. The precooler was a component, not a product. And in the aerospace industry, the distance between a validated component and a certified engine is measured not in years but in decades, and not in millions but in billions.
The SABRE story is not over. The intellectual property exists. The precooler technology has applications beyond spaceplanes — in hypersonic aircraft, industrial heat exchangers, even Formula One cooling systems. Someone will buy it, and some version of the technology will find its way into operational hardware. But the Skylon dream — a British single-stage-to-orbit spaceplane, taking off from a runway in Oxfordshire and delivering satellites to orbit as routinely as a 747 delivers passengers to New York — that dream died in the autumn of 2024, in an administrator's office, after 35 years and £150 million. It is, in its way, the most British space story imaginable: visionary engineering, world-class science, and not quite enough money or institutional patience to see it through.
Surrey Satellite Technology: The Quiet Revolution from Guildford
If Reaction Engines represents the tragedy of British space ambition — the gap between what was conceived and what was achieved — then Surrey Satellite Technology Ltd represents its quiet triumph. SSTL is arguably the most influential space company that most people have never heard of, and its story begins not in a government laboratory or a corporate boardroom but in a university electronics workshop, with a young researcher who was tracking Russian weather satellites using amateur radio equipment.
In 1975, Martin Sweeting was a graduate student at the University of Surrey in Guildford, southwest of London. His interest in amateur radio had led him to experiment with receiving signals from Soviet meteorological satellites — a hobby that evolved into a radical question: if you could build satellite ground stations from commercial off-the-shelf components, could you build the satellites themselves the same way?
The established satellite industry of the 1970s and 1980s would have answered that question with a firm no. Satellites were bespoke, hand-built machines, assembled in pristine cleanrooms from radiation-hardened, military-specification components that cost orders of magnitude more than their commercial equivalents. A typical communications satellite cost hundreds of millions of dollars. The idea that you could build a useful spacecraft from the same components found in consumer electronics — and do it for a tiny fraction of the cost — was considered, to put it politely, eccentric.
Sweeting and his team built one anyway. UoSAT-1, assembled in a small university lab using a cleanroom improvised from materials bought at a local hardware store, with circuit boards designed by hand on a kitchen table, was launched as a secondary payload on a NASA Delta rocket on October 6, 1981. It weighed 52 kilograms. It cost a fraction of what any satellite had ever cost before. It was designed for a three-year mission. It lasted more than eight years.
UoSAT-1 was the first modern microsatellite — the proof of concept that cheap, small, rapidly built spacecraft could perform useful work in orbit. It was followed by UoSAT-2 in 1984, which demonstrated store-and-forward digital communications from space. The success of these missions led directly to the founding of Surrey Satellite Technology Ltd in 1985, spun out from the university with a starting capital of just £100 and four employees.
From University Spin-Out to Global Pioneer
What followed over the next four decades was a systematic demonstration that small satellites were not toys or academic curiosities but commercially viable platforms capable of Earth observation, communications, navigation, and scientific research. SSTL built satellites for countries that had never operated spacecraft before — South Korea, Chile, Nigeria, Algeria, Turkey — often training their engineers in Guildford as part of the contract. The model was not just to sell a satellite but to transfer the knowledge to build one.
The Disaster Monitoring Constellation (DMC), launched between 2002 and 2009, was a landmark. A network of five small Earth observation satellites built by SSTL for an international consortium, DMC provided 32-meter-resolution multispectral imagery of the Earth's surface, with a revisit time of approximately one day. It was the first operational satellite constellation built primarily from small, affordable spacecraft — and it used the Internet Protocol for data transfer between satellites and ground stations, effectively extending the internet into orbit years before the concept became fashionable.
In 2004, Elon Musk — then still in the early years of SpaceX — arranged for the company to acquire a 10 percent stake in SSTL. Musk described SSTL as "probably the world leader in small satellites." The stake was later sold when SpaceX's own trajectory diverged, but the endorsement from the man who would go on to build the world's largest satellite constellation underscored what the space industry already knew: SSTL had pioneered something that mattered.
By 2008, the University of Surrey agreed to sell its majority stake — roughly 80 percent — to EADS Astrium (now Airbus Defence and Space). SSTL became a wholly owned subsidiary of Airbus, but maintained significant operational independence, continuing to design and build satellites from its Guildford facility. As of 2026, the company has built, launched, and operated 74 satellites for 22 countries across more than four decades — a record that places it among the most prolific satellite manufacturers in history relative to its size.
The SSTL Legacy
SSTL's influence extends far beyond its own order book. The company demonstrated, decades before the CubeSat boom of the 2010s, that the satellite industry's assumption — bigger is better, more expensive is more reliable — was wrong. Small satellites built from commercial components could be launched faster, replaced more easily, and operated in constellations that provided capabilities no single large satellite could match. Every CubeSat company, every small satellite constellation operator, every "NewSpace" startup that builds spacecraft from commercial parts owes an intellectual debt to what Martin Sweeting started in a Guildford workshop in the late 1970s.
Sweeting was knighted in 2002 for his services to small satellite engineering. He remains executive chairman of SSTL and a Distinguished Professor at the University of Surrey. The company's current projects include Lunar Pathfinder — a telecommunications relay satellite for lunar missions — and CarbSAR, an in-orbit demonstration combining SSTL's Carbonite platform with a deployable synthetic aperture radar antenna. Both are scheduled for launch in 2026.
The SSTL story is, in many ways, the opposite of the Reaction Engines story. Where SABRE was a moonshot that never reached the moon, SSTL was an incremental revolution — each satellite slightly more capable, each mission slightly more ambitious, each contract slightly larger, until the company that started with £100 had reshaped an industry worth tens of billions.
Skyrora: Ukrainian Roots, Scottish Ambitions
With Orbex gone and Reaction Engines in administration, the question of who will carry British launch ambitions forward has a clear front-runner — and it is a company with a story as improbable as any in the UK space sector.
Skyrora was founded in 2017 by Volodymyr Levykin, a Ukrainian-born software engineer and entrepreneur who had built a successful career in Silicon Valley before turning his attention to rocketry. Levykin's insight was that Ukraine possessed deep rocket engineering expertise — the legacy of the Soviet-era Yuzhnoye Design Bureau, which had designed some of the most capable intercontinental ballistic missiles and space launch vehicles ever built — and that this expertise could be combined with the UK's emerging launch infrastructure and regulatory framework to create a competitive small satellite launch company.
The result was Skyrora, headquartered in Edinburgh, with the explicit mission of providing sovereign UK launch capability for small satellites. The company's approach combines several distinctive elements: 3D-printed rocket engines manufactured on proprietary Skyprint machines, a commitment to sustainable propulsion, and a stepped development program that begins with suborbital vehicles and progresses to orbital launch.
Skylark L and the First UK Launch License
Skyrora's suborbital vehicle, Skylark L, is a single-stage sounding rocket designed for scientific research, technology demonstration, and microgravity experiments. On August 5, 2025, the UK Civil Aviation Authority granted Skyrora a Spaceflight Operator Licence — the first vertical launch license ever issued to a British company for launches from UK soil. The license authorizes up to 16 Skylark L launches per year from SaxaVord Spaceport on Shetland, with a maximum of two per month.
The license was a regulatory milestone: proof that the Space Industry Act 2018 worked, that the CAA's licensing process could deliver a result, and that a British company could navigate the regulatory path from application to authorization. It was also, in practical terms, a stepping stone. Skylark L is a suborbital vehicle. The real prize is orbital.
Skyrora XL: The Orbital Play
The Skyrora XL is a three-stage orbital launch vehicle standing approximately 23 meters (75 feet) tall, designed to place 315 kilograms into sun-synchronous orbit. The first stage is powered by nine Skyforce engines — 3D-printed, burning a fuel called Ecosene (a kerosene equivalent derived from unrecyclable plastic waste, which Skyrora claims produces approximately 45 percent fewer greenhouse gas emissions than conventional rocket-grade kerosene) and high-test peroxide as the oxidizer.
The choice of high-test peroxide is historically resonant. HTP was the oxidizer used by Black Knight and Black Arrow — the rockets that gave Britain its first and only indigenous orbital launch capability in 1971. Skyrora's use of HTP, updated with modern propellant chemistry and engine design, is both a practical engineering choice (HTP is dense, relatively safe to handle, and self-decomposing) and a deliberate nod to British rocketry heritage.
By late 2025, Skyrora had completed 3D printing of all nine Skyforce engines for the XL's first stage and was planning a full first-stage static fire test. If development proceeds on schedule — always a conditional statement in the rocket business — Skyrora XL could attempt its first orbital launch from SaxaVord as early as late 2026 or 2027.
The Polyakov Investment and Orbex Aftermath
In November 2025, Skyrora's trajectory received a significant boost when Ukrainian entrepreneur Max Polyakov — the man who had previously rescued the American rocket company Firefly Aerospace from near-bankruptcy and turned it into a successful launch operator with NASA contracts — made a major strategic investment in Skyrora. Polyakov's track record in building launch companies gave the investment credibility beyond its monetary value: if anyone understood what it took to get a small rocket company from development to operational launches, it was the man who had done it with Firefly.
Then, in February 2026, when Orbex collapsed into insolvency, Skyrora moved quickly. The company announced its intention to explore the purchase of select Orbex assets — with particular interest in the Sutherland Spaceport — potentially investing up to £10 million. The logic was sound: Skyrora already had a launch license for SaxaVord, but a second launch site at Sutherland would provide operational flexibility, redundancy, and the ability to serve customers who needed different orbital inclinations. More importantly, Sutherland had been built with £17.3 million in public funding. Letting that investment rot on a Scottish peninsula would have been a waste that even the most austerity-minded Treasury official could not justify.
Whether Skyrora succeeds where Orbex failed remains to be seen. The company has advantages Orbex lacked: a simpler vehicle architecture, a proven suborbital platform, a launch license already in hand, and an investor with direct experience building launch companies. But building rockets is still the hardest thing humans do short of nuclear physics, and the history of small launch vehicle startups is a history of optimistic timelines meeting unforgiving engineering reality.
Space Insurance at Lloyd's of London: Britain's Hidden Space Superpower
If you ask a space enthusiast to name the most important British contribution to the global space industry, they will mention satellites, or small spacecraft, or perhaps Reaction Engines. Almost no one will say insurance. And almost no one will be right.
The London insurance market — centered on Lloyd's of London, the 338-year-old institution housed in Richard Rogers' inside-out building in the City of London — is the financial backbone of the global space industry. Without it, most satellites would never be built, most rockets would never launch, and most operators would never secure the financing needed to commission a spacecraft. Space insurance is invisible infrastructure, and London dominates it to a degree that has no parallel in any other segment of the space economy.
How Space Insurance Works
The first satellite insurance policy was written at Lloyd's in April 1965, covering pre-launch physical damage to Intelsat I — the "Early Bird" satellite, the first commercial communications satellite placed in geostationary orbit. Since then, Lloyd's has developed the most sophisticated space risk assessment capability in the world, with more than 34 specialist space underwriting syndicates operating within the market.
Space insurance covers four distinct phases of a satellite's lifecycle:
Pre-launch insurance covers the satellite from the moment it leaves the factory, through transportation to the launch site, integration with the launch vehicle, fueling, and all ground operations up to ignition. If a crane drops the satellite during integration, or a fueling accident damages the spacecraft, pre-launch insurance pays.
Launch insurance is the most expensive and highest-risk phase. It covers the satellite from the moment of ignition through ascent, orbital insertion, deployment of solar panels and antennas, in-orbit testing, and commissioning into operational service — typically a period of 12 months after launch. If the rocket explodes on the pad, if the upper stage fails to ignite, if the satellite reaches the wrong orbit, or if a solar panel fails to deploy, launch insurance pays.
In-orbit insurance covers the satellite during its operational lifetime, typically in one-year renewable policies. If a component fails and the satellite loses capacity, if a thruster malfunction shortens the satellite's operational life, or if a micrometeorite impact damages the spacecraft, in-orbit insurance pays.
Third-party liability insurance covers legal liabilities for damage caused by the space object to third parties — on the ground, during launch, or in orbit. Under the Outer Space Treaty and national space legislation (including the UK's Space Industry Act 2018), launching states bear international liability for damage caused by their space objects. Third-party liability insurance protects operators and launching states against claims.
The Numbers
Premiums for launch insurance typically range from 5 to 20 percent of the insured value, depending on the launch vehicle's track record, the satellite's complexity, and market conditions. A single launch insurance policy for a large geostationary communications satellite might cover $300 to $500 million in value, with the premium running $15 to $100 million. For a proven launch vehicle like Falcon 9 or Ariane 6, premiums tend toward the lower end; for newer or less reliable vehicles, they climb steeply.
The global space insurance market generated approximately $4.06 billion in premiums in 2025 and is projected to reach $4.43 billion in 2026. Europe accounts for approximately 35 percent of global space insurance premiums, with Lloyd's of London and the wider London market representing the single largest concentration of space underwriting expertise in the world. The space risk currently underwritten at Lloyd's alone is estimated at between £125 million and £150 million in annual premiums — but the significance of the London market extends far beyond its direct premium volume. Lloyd's syndicates frequently lead placements that are then shared with reinsurers worldwide, meaning that London's influence on pricing, policy terms, and risk assessment standards ripples through the entire global space insurance ecosystem.
Notable Claims: When Things Go Wrong
The space insurance industry's loss history reads like a catalogue of the ways orbital technology can fail. The largest single space insurance claim as of early 2026 was Viasat-3 F1, a geostationary broadband satellite that suffered a deployment anomaly in 2023, resulting in a $770 million claim. Inmarsat 6-F2, another geostationary satellite, generated a $348 million loss in the same year. The 2019 failure of the Vega rocket carrying a UAE military observation satellite cost insurers $411 million. Mexico's Centenario mobile communications satellite, lost in a 2015 Proton launch failure, resulted in a $390.7 million claim.
These are enormous sums, and they are borne by a relatively small community of specialist underwriters. A single bad year — 2023, for example, with the Viasat-3 and Inmarsat 6-F2 losses — can wipe out several years of premium income. The space insurance market is, by its nature, volatile: losses are infrequent but catastrophic, and the underwriters who survive in this market do so through deep technical expertise, disciplined risk selection, and the Lloyd's market's unique structure, which allows syndicates to share risk across dozens of capital providers.
Why London?
London's dominance of space insurance is not an accident. It is a product of history (Lloyd's has been insuring unconventional risks since Edward Lloyd's coffee house in the 1680s), expertise (the concentration of specialist space underwriters, brokers, and loss adjusters in the City of London has no equivalent elsewhere), and the Lloyd's market structure itself, which allows syndicates to form, share risk, and access a global client base through a single marketplace. Paris, Munich, and New York all have space insurance capabilities, but no other market matches London's depth of specialist knowledge or its ability to assemble large, complex placements quickly.
For the UK space economy, this is a genuinely unique competitive advantage. Launch vehicles can be built anywhere. Satellites can be manufactured in dozens of countries. But the financial infrastructure that underwrites the risk of putting those satellites on those rockets and operating them for 15 years in the hostile environment of space — that infrastructure is disproportionately British, and it is not easily replicated.
UK Defense Space: Skynet, Space Command, and the Shadow of Ukraine
The United Kingdom's military space capabilities have operated in deliberate obscurity for decades — a product of both national security requirements and the British institutional preference for not discussing defense programs in public. But the establishment of UK Space Command in 2021, the acceleration of the Skynet 6 satellite program, and the hard lessons of the Ukraine war have pushed defense space into a more prominent position in national strategy than at any point since the Cold War.
Skynet: Britain's Military Backbone in Orbit
The Skynet program is one of the longest-running military satellite communications systems in the world, stretching back to Skynet 1A, launched in 1969 — two years before Prospero, and two years before the UK cancelled its own launch vehicle. The irony is characteristic: Britain gave up the ability to launch its own satellites while simultaneously becoming one of the earliest operators of military communications satellites, relying on American rockets to place British military hardware in orbit.
The current operational fleet consists of the Skynet 5 series — three geostationary satellites built by Airbus (then EADS Astrium) and launched between 2007 and 2012, providing secure, jam-resistant communications for UK armed forces and NATO allies. The Skynet 5 system operates under a Private Finance Initiative (PFI) contract with Airbus, under which the company owns and operates the satellites while the Ministry of Defence purchases communications capacity as a service — a model that was innovative when it was signed in 2003 but that the MOD has since concluded gives it insufficient control over a sovereign capability.
The successor program, Skynet 6, represents a fundamental shift. Skynet 6A — the first satellite in the new generation — is being built entirely in the United Kingdom, at Airbus facilities in Stevenage and Portsmouth, based on the Airbus Eurostar Neo satellite platform. It is being tested at the government-funded National Satellite Test Facility (NSTF) at Harwell, Oxfordshire — itself a new capability, designed to give the UK sovereign satellite testing infrastructure that previously had to be sourced from facilities in continental Europe.
Skynet 6A completed its initial testing phase at Harwell in early 2025, including electromagnetic compatibility assessments, extreme temperature tolerance, and vibration resistance. The satellite offers 3.5 times the communications capacity of its Skynet 5 predecessors and is scheduled for launch by SpaceX in 2026, with operational service beginning in 2027. The program directly supports 550 skilled jobs across the UK and is designed to provide secure military communications for at least 15 years.
Beyond Skynet 6A, the broader Skynet 6 program includes the Wideband Satellite System — a procurement for multiple medium-sized geostationary satellites that will form the enduring capability for UK military SATCOM through the 2030s and 2040s. A preferred bidder for this element was expected to be selected in early 2026.
UK Space Command
UK Space Command was established on April 1, 2021, at RAF High Wycombe, as a joint command staffed by personnel from the Royal Navy, British Army, Royal Air Force, civil servants, and contractors. Its creation reflected a belated but decisive recognition that space is a contested operational domain — not merely a place where useful satellites orbit, but a potential theater of conflict where adversaries might seek to deny, disrupt, or destroy space-based capabilities.
Space Command's responsibilities include space domain awareness (tracking objects in orbit and understanding the space environment), space operations (operating military satellites and ground systems), and space control (protecting UK and allied space assets). It has taken command of RAF Fylingdales, the ballistic missile early warning station on the North York Moors, which operates a three-faced phased-array radar providing 360-degree surveillance of space — the only such radar in the US-led Space Surveillance Network. RAF Fylingdales tracks thousands of objects in orbit and provides missile launch detection for both the UK and the United States, a capability that has been shared between the two nations since the facility was built in 1963.
The UK is also a member of the Combined Space Operations Initiative alongside the United States, Canada, Australia, France, Germany, and New Zealand — an alliance that shares space situational awareness data and coordinates responses to threats in the space domain. Through the Five Eyes intelligence partnership (UK, US, Canada, Australia, New Zealand), Britain participates in the most sensitive satellite intelligence sharing arrangements in the world.
The ISTARI Program and the Ukraine Effect
In February 2025, the Ministry of Defence awarded Airbus a £127 million contract to design and build two Oberon synthetic aperture radar (SAR) satellites — spacecraft capable of producing high-resolution radar imagery of the Earth's surface in any weather conditions, day or night. The Oberon satellites will join Tyche, the first satellite launched for UK Space Command since its formation, as part of the ISTARI program — the MOD's plan to deploy a growing constellation of intelligence, surveillance, and reconnaissance (ISR) satellites by 2031.
The ISTARI program was accelerated by the Ukraine war. The conflict demonstrated, in brutal and unmistakable terms, how space assets shape modern warfare. Ukraine, a country with no indigenous satellite capability, made devastating use of commercial satellite imagery and communications — from Maxar and Planet Labs for intelligence, from Starlink for battlefield communications — to fight a vastly larger adversary. The lesson was not lost on British defense planners: space is no longer a supporting capability for military operations. It is a prerequisite. And dependence on commercial or allied systems, while useful, is not the same as sovereign capability.
The Ukraine war also demonstrated the vulnerability of space systems to electronic warfare. Russia's repeated attempts to jam Starlink terminals, its cyberattack on the Viasat KA-SAT network on the first day of the invasion, and its development of anti-satellite weapons all reinforced the need for resilient, redundant, and diversified space architectures — not a single exquisite satellite in geostationary orbit, but constellations of smaller, more replaceable spacecraft in multiple orbital regimes.
The UK's defense space trajectory is clear: more satellites, more diverse orbits, more sovereign capability, and tighter integration with the Five Eyes and NATO space coalitions. The budget — while growing — remains modest by American standards. But the institutional machinery is now in place, and the lessons of Ukraine have given defense space a political urgency it has never previously enjoyed in Whitehall.
Glasgow: Satellite Manufacturing Capital of Europe
The story of Glasgow's transformation from a post-industrial city mourning its shipyards to the satellite manufacturing capital of Europe is one of the more improbable chapters in British economic geography. Glasgow builds more small satellites than any other city in Europe, and in the whole world, only California surpasses Scotland's output.
The cluster effect began with Clyde Space (now AAC Clyde Space), founded in 2005 by Craig Clark to take advantage of the emerging market for CubeSats — standardized miniature satellites based on units of 10 centimeters cubed. The company grew from a small operation building individual CubeSats into a significant manufacturer of small satellite platforms, merging with Swedish company AAC Microtec in 2017 to form AAC Clyde Space, which is now listed on the Nasdaq Stockholm exchange and operates from facilities in Glasgow, Sweden, and the Netherlands.
Spire Global, an American-founded company that chose Glasgow as its satellite manufacturing center, has built over 175 satellites in the city. Spire owns and operates one of the largest commercial satellite constellations in the world — over 100 operational nanosatellites collecting data on global shipping movements, aircraft positions, and weather patterns. The decision to base satellite production in Glasgow rather than San Francisco was driven by Scotland's concentration of engineering talent, competitive operating costs, and the proximity to the University of Strathclyde's space engineering program.
The ecosystem extends beyond these anchor companies. Craft Prospect, Alba Orbital, and a growing number of smaller firms provide components, software, ground systems, and mission operations services. The University of Strathclyde and the University of Glasgow produce a steady pipeline of graduates with relevant skills. The Scottish government has invested consistently in the space sector through Scottish Enterprise and the Scottish National Investment Bank.
In March 2026, the cluster's capabilities were demonstrated when Glasgow-built satellites from both Spire Global and AAC Clyde Space launched aboard a SpaceX Transporter rideshare mission, funded in part by the UK Space Agency through ESA's Pioneer Programme. The satellites demonstrated advanced capabilities including optical inter-satellite laser links — technology that allows satellites to communicate with each other directly, without routing data through ground stations, a capability critical for next-generation constellations.
The Glasgow satellite cluster is a textbook example of the agglomeration effects that economists describe but rarely observe forming in real time. Companies locate near other companies in the same sector. Talent pools deepen. Supply chains develop. Universities adjust their curricula. Local government invests in supporting infrastructure. The result is a self-reinforcing ecosystem that becomes increasingly difficult for rival cities to replicate — precisely the kind of competitive moat that economic development agencies dream about.
Scotland now employs more than 8,500 people in space-related activities — nearly one in five of all UK space jobs. For a country of 5.5 million people, this is an extraordinary concentration, and it is growing.
The Path Forward: Can Britain Match Ambition with Investment?
The evidence, assembled across these two articles, points in two directions simultaneously — which is, perhaps, the most British outcome possible.
On one hand, the UK space sector is real, substantial, and growing. £18.6 billion in annual revenue. 55,550 direct jobs. 74 satellites built by SSTL alone. Lloyd's of London insuring a significant share of every satellite launch on Earth. Glasgow manufacturing more small satellites than any city in Europe. A Skynet 6 military satellite being built and tested entirely on British soil for the first time. A Skyrora rocket with a launch license in hand. A regulatory framework that works. An ESA membership that continues to return contracts to British industry.
On the other hand, Reaction Engines collapsed after 35 years and £150 million because it could not bridge the gap between brilliant engineering and commercial product. Orbex collapsed before it ever launched a rocket. The 10 percent global market share target was quietly abandoned. UKSA is being absorbed into a government department. The House of Lords' 2025 report on the space economy was titled The Space Economy: Act Now or Lose Out — not exactly a ringing endorsement of the status quo.
The tension is structural, not temporary. Britain excels at the high-value, knowledge-intensive segments of the space economy — satellite design, data services, financial risk management, defense communications, Earth observation analytics — but it has never developed the sustained industrial policy or the scale of public investment that underpins the space programs of France, Germany, Japan, India, or China. The UK spends roughly £668 million per year on civil space. France spends approximately €2.8 billion through CNES alone, in addition to its ESA contribution. The gap is not closing.
The cultural dimension matters too. The British instinct for understatement — the tendency to describe a £18.6 billion industry as "rather good, actually" rather than as a national strategic asset requiring maximum political and financial support — has real consequences. It means that space rarely commands the sustained political attention that drives large-scale investment decisions. It means that individual companies like Reaction Engines can burn through decades and hundreds of millions of pounds without ever receiving the kind of institutional backing that would have been routine in France or Germany. It means that the UK's genuine strengths — SSTL's satellite heritage, Lloyd's insurance dominance, Glasgow's manufacturing cluster, Skynet's defense capability — are systematically undersold, both to the British public and to the international community.
And yet the sector keeps growing. The boffins keep building. The underwriters keep calculating. The entrepreneurs — some of them Ukrainian, some of them Scottish, some of them working from Guildford workshops that have not changed much since the 1980s — keep pushing toward orbit.
Arthur C. Clarke imagined the geostationary satellite from a desk in Britain. Martin Sweeting built the first modern microsatellite in a university workshop. Lloyd's of London wrote the first satellite insurance policy before NASA had landed on the Moon. The intellectual and commercial foundations of British space capability are not shallow. They are deep, and they are unique.
The question that will define the next decade is whether those foundations will finally receive the investment and institutional support they deserve — or whether Britain will continue to do extraordinary things in space while pretending, with characteristic modesty, that they are not particularly important.
The stars, as Wilde observed, are still up there. And the British are still looking.
