UK RAF Uses Lasers and Jammers to Disrupt Hostile Satellites as GPS Risks Grow

The UK Royal Air Force (RAF) has been deploying ground-based lasers and jammers to interfere with hostile satellites for about a year, aiming to protect sensitive military assets. Defence officials warn that GPS disruptions could cost the British economy £10 billion per week, highlighting the growing risks of space-based threats.

RAF Deploys Ground-Based Electronic Warfare to Disrupt Satellites

According to TechRadar, the UK Royal Air Force (RAF) has been using ground-based lasers and jammers for about a year to interfere with hostile satellites. These systems are designed to disrupt satellite communications and navigation using powerful electronic signals, while lasers can blind or degrade satellite sensors.

The technology is reportedly being used to prevent adversaries from tracking sensitive British military assets, such as nuclear-armed submarines or special forces operations. British defence officials claim their terrestrial electronic warfare capabilities are among the most advanced in the world.

Economic and Security Risks of GPS Disruption

The UK government has warned that a loss of GPS services could have severe economic consequences, costing the British economy £1.4 billion per day, or approximately £10 billion per week. This underscores the dependence of modern economies on satellite-based navigation and timing systems.

TechRadar reports that Russian satellite activity has been linked to GPS disruptions across Europe and Canada. In May 2026, British forces tracked five Russian satellites operating near two Finnish commercial satellites, raising concerns about escalating space-based threats.

UK Expands Space Defence Capabilities

The RAF has established a dedicated Space Effects Squadron to defend British space assets against hostile activity. The UK operates a small number of military satellites that support surveillance and communications, and it collaborates closely with the United States Space Force to enhance its space defence capabilities.

According to TechRadar, the United States has deployed an unspecified weapon in space to protect its satellites. Meanwhile, Washington has accused Russia and China of developing space-based weapons, including electronic jammers, lasers, and projectiles.

Developing: what is not yet confirmed

The following is reported but has not been independently confirmed.

Some claims reported by TechRadar remain unverified, including the specific effectiveness of the RAF’s electronic warfare systems and the extent of their use against hostile satellites. The details of how often and under what conditions these systems are deployed have not been confirmed.

The reported tracking of Russian satellites near Finnish commercial satellites in May 2026 has not been independently verified, though British defence officials have previously warned about provocative activities involving space-based systems. Air Chief Marshal Harv Smyth stated that adversaries were engaging in increasingly irresponsible and provocative behavior in space.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

This development signals a shift in how nations are approaching space as a contested domain. While the UK’s investment in electronic warfare reflects growing concerns about satellite vulnerability, it also highlights the broader trend of militarizing space. For startups and operators in the aerospace and defence sectors, this could mean new opportunities—whether in developing countermeasures, resilient satellite technologies, or alternative navigation systems that reduce reliance on GPS.

However, the economic warning about GPS disruption is a wake-up call for businesses far beyond defence. Industries like logistics, finance, and telecommunications rely heavily on satellite timing and navigation. Founders in these sectors may need to start stress-testing their operations for GPS outages and exploring backup systems. The collaboration between the UK and the US also suggests that allied nations are prioritizing shared defences, which could shape future procurement and innovation partnerships.

Key takeaways

• The RAF has deployed ground-based electronic warfare equipment, including lasers and jammers, to interfere with hostile satellites.

• The UK is expanding its space defence capabilities, including the creation of a Space Effects Squadron.
• Russia and China are accused of developing space-based weapons, raising global security concerns.
• British forces tracked Russian satellites near Finnish commercial satellites in May 2026, highlighting growing space threats.

FAQ

What is the RAF’s Space Effects Squadron?

The Space Effects Squadron is a dedicated unit established by the RAF to defend British space assets from hostile activity, including satellite disruption and electronic warfare.

How could GPS disruption affect the UK economy?

The UK government estimates that a loss of GPS services could cost the economy £1.4 billion per day, or £10 billion per week, due to disruptions in navigation, timing, and communications across multiple industries.

What are space-based weapons?

Space-based weapons refer to systems designed to disable, disrupt, or destroy satellites or other space assets. These can include electronic jammers, lasers, projectiles, or other technologies aimed at interfering with satellite operations.

Why is the UK collaborating with the United States Space Force?

The UK operates a limited number of military satellites and relies on partnerships with allies like the United States to enhance its space defence capabilities, share intelligence, and coordinate responses to threats.

What are the risks of relying on satellite-based systems?

Reliance on satellite-based systems like GPS introduces vulnerabilities to electronic warfare, cyberattacks, and physical interference. Disruptions can have cascading effects on industries ranging from logistics to finance, highlighting the need for resilient alternatives.
