The Royal Navy seized £142 million worth of cocaine when a helicopter crashed into smugglers in the Caribbean.
HMS Dauntless released its Wildcat helicopter when its anti-missile radar spotted a speedboat speeding toward the United States.
Commando snipers on the plane had the smugglers in their sights and forced the boat to stop.
U.S. Coast Guard allies then boardedship and seized 1.2 tons of cocaine.
A source said: “It was drama on the high seas and a brilliant operation.”
“Our people jumped onto the boat from the air and brought it to a halt.
“The police went on board and found a huge load of cocaine.
“It is one of the largest ever seizures by the Royal Navy as part of its drug patrol activity.”
“It will be a huge kick in the worldfor the cartel behind the smuggling plot.”
It was the first time that the Type 45 destroyer’s Samson radar was used to disrupt smuggling gangs.
It usually searches for enemy incoming jets and missiles.
It can track 1,000 objects of sizeBullets travel at three times the speed of sound.
In a second mission, the radar tracked a smuggling plane carrying 550 kg of cocaine from Venezuela.
The ship’s captain, Commander Ben Dorrington, said: “I am immensely proud of what we have achieved.”
