THIS is the shocking moment a Russian stealth submarine crashed into a Royal Navy warship in an unbelievable clash.
A crew member can be heard shouting "what the f**k have I just hit?" after the HMS Northumberland struck the "hunter-killer" sub in the icy north Atlantic.
The dramatic collision - which is believed to have been an accident - was caught on film by a Channel 5 TV crew whilst shooting for the show Warship: Life At Sea, which airs on Mondays at 9pm.
It is thought to be the first collision between Russian and Royal Navy vessels since the Cold War.
The unbelievable clip shows crew members closing in on the submarine in late 2020 before disaster strikes.
