Britain to test fire nuke missile in major show-of-force with sub launching 44ft Trident 2 for first time since 2016

t is the first time the UK has test fired a missile since a botched launch in 2016.

And it follows a drumbeat of warnings that the world is careering to World War Three.

The Sun understands the £4bn sub is scheduled to test fire an unarmed missile after completing a seven year refit in Plymouth.

The tests are the final hurdle for HMS Vanguard to re-enter service as part of the UK’s nuclear deterrent fleet.
