The posters point out that if a Trident submarine actually launched its nuclear missiles it would very likely be destroyed in a counterattack.
This, they claim, makes nuclear submariners little more than suicide bombers, whose job is to kill millions of civilians.
The satirical posters have appeared at bus stops across London.
His work has the endorsement of Veterans for Peace UK.
Picking up on the campaign on Friday, Rupert Murdoch-owned tabloid the Sun said the posters had sparked “fury.”
However, former Royal Navy weapons engineer William McNeilly, who was kicked out of the Navy after handing WikiLeaks a dossier of serious security and safety failures in 2015, told RT the campaign’s message is accurate.
“The Sun claims that the message in the posters is ‘fake,’” McNeilly told RT on Friday. “It is well known on board nuclear submarines that the Trident submarine on patrol will be the prime target in a nuclear war.”
The former submariner pointed out that once a submarine starts launching missiles it becomes immediately detectable. Those on board know “it is extremely unlikely that they would survive a major war against Russia. They are ready and prepared to be suicide bombers.”
Referring to the recent allegations of a government cover-up of a failed nuclear launch in 2016, McNeilly said: “Judging by the last missile test, it is not unlikely that the Trident submarines would nuke the United States by accident.”
