The UK government has started working on Atlantic Bastion, a new military 
program aimed at strengthening the security of its undersea critical 
infrastructure. 

In a press release published on the UK.gov site earlier this week, it was 
said that Atlantic Bastions goal was to secure these assets from Russian 
undersea threats. 

Russian submarine and underwater activity has reportedly picked up in recent 
years, and the country has been hard at work modernizing its fleet to target 
critical undersea cables and pipelines. Europes eastern neighbor has 
allegedly been seen mapping out key locations of undersea critical 
infrastructure , with the UK government mentioning Russian spy ship Yantar 
that was recently spotted around UK waters.

This year alone, the UK will have invested millions of pounds into 
development and testing of innovative anti-submarine sensor technology. 

Atlantic Bastion will be a combination of autonomous surface and underwater 
vessels, cutting-edge digital infrastructure, and warships and patrol 
aircraft. This will enable the UK navy to act against its adversaries with 
unprecedented effectiveness across vast areas of ocean. 

The next phase of action, which should kick off in the coming weeks, is to 
take the projects from concept to the frontline. Some capabilities are 
expected to be deployed in the water next year, with investments accelerating 
in the year that follows. 

In recent months, multiple undersea internet ( fibre-optic ) cables in the 
Baltic Sea region have been damaged or cut. Many observers believe it to be 
closely tied to the Russia-Ukraine war. In November 2024 two major submarine 
data cables, including CLion1 (which connects Finland and Germany), were 
discovered damaged or severed, and around the same time, a fibre-optic cable 
between Lithuania and Sweden (via the island of Gotland) was also cut. 

In late December 2024, another incident hit a power cable between Finland and 
Estonia, and multiple associated telecom cables were reportedly disrupted 
too. A vessel believed linked to Russias so-called shadow fleet was seized by 
Finnish authorities in connection with that outage.
