Retired Royal Navy Rear Admiral Chris Parry stated that Russia would not be able to defend itself against a massive ICBM strike.
"One Trident submarine has the ability to incinerate 40 Russian cities very quickly. That is a lot of food for thought for Putin and that should make any world leader fearful," he told The Telegraph.
However, concerns have been raised about the state of Britain’s nuclear fleet. The Vanguard-class submarines are more than 25 years old, and two recent missile tests have ended in failure.
The UK possesses four Vanguard-class nuclear submarines:
- HMS Victorious,
- HMS Vanguard,
- HMS Vigilant,
- and HMS Vengeance.
Each is equipped with Trident ICBMs capable of carrying nuclear warheads.
