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.
