On May 23, 1982 a number of explosions were heard near HMS Valiant, getting progresively closer. The 5th (and last) one being loud enough to shake the submarine and its crew considerably. HMS Valiant suffered minor damage. The "attacker" were a flight of Skyhawk returning to San Julian air base, jettisoning its ordenance in the middle of nowhere. But HMS Valiant was in the middle of nowhere at the time. According to its CO, Tom Le Marchand: "We were lucky, but a few feet closer and it might have been something of a bad luck story."
The Argentine Air Force was very close to the first kill ever of an SSN...by pure chance.
Valiant was there at the time:
