UK Enhances Satellite Defense Capabilities Against Space Threats

UK's Strategic Response to Space Threats

Government Investment in Space Security

LONDON -Britain is building sensors to counter lasers that adversaries might use to blind satellites or intercept and interrupt communications, the UK government said on Friday. 

Global Military Space Concerns

The government said it will spend about £500,000 ($672,750) on the project, which involves UK Space Command and the UK Space Agency. 

Comparative Spending on Space Defense

A UK-government commissioned security review published this summer said Britain urgently needs to bolster defences for military space systems as adversaries improve their own abilities to attack in space. 

The Strategic Defence Review called for Britain to invest in its own space attack capabilities, along with intelligence and navigation networks as well as satellite communications.

Militaries depend on satellites for communication, surveillance, and guidance data for troops, warships and weapons. Without their space assets, Western militaries “can't effectively understand, move, communicate, and fight,” General Paul Tedman, head of UK Space Command, said on Wednesday during a visit to the RAF Fylingdales radar station. 

European and other Western military space officials are warning about increasing hostile activity in space that could disrupt the operations of ground and sea forces. 

“You’ve got to be able to protect your systems in space,” Tedman said at RAF Fylingdales, which provides missile warning and space surveillance to the United States and Britain. 

While the U.S. dominates government spending on space globally, France and Germany were Europe’s two largest spenders on space last year, according to France-based consulting firm Novaspace.

Last week, Germany’s defence minister warned about a growing threat posed by Russia and announced Berlin would invest 35 billion euros ($41.09 billion) over the next five years on space security. 

France’s space-related initiatives include leading a 1.5-billion euro investment in Eutelsat, a French rival to Elon Musk’s Starlink satellite communications service.
