Description:
Project Atlantic Bastion is kicking off and should help secure UK undersea
critical infrastructure from the Russians.

FULL STORY

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.
