Before she was commissioned, the British Government stated that once the Vanguard submarines became fully operational, they would only carry 200 warheads.
On 31 March 2011, while on a training exercise Vengeance suffered a blockage in her propulsor causing a reduction in propulsion. The boat returned to Faslane naval base on the surface under her own power. According to the MOD the problems were not nuclear related.
In 2012, Vengeance started a 40 month refit at HMNB Devonport near Plymouth which refueled her reactor and re-newed her machinery and electronics. During that period her sister ship Vigilant took her place in the patrol rotations. She sailed from Devonport on 4 December 2015, her place in refit being taken by Vanguard. Vengeance then went through trials from January 2016 to June 2016 and fired an unarmed D5 missile during her Demonstration and Shakedown Operation (DASO) which allowed her to return to the fleet. Whilst the firing of the missile was a success, the missile itself suffered a failure during flight and the test was terminated.
