The Secret Behind the Black Prince Submarines! On October 31, 1983, the K-324 snagged the frigate USS McCloy's towed sonar array cable 282 miles west of Bermuda, causing damage to the submarine's propeller. The submarine was towed to Cienfuegos, Cuba for repairs by a Soviet salvage ship beginning on November 5. Soviet technicians recovered some parts of McCloy´s array. The K-324 was again involved in operations around US waters in 1985. She was reported to have detected American SSBNs on three different times, tailing them for 28 hours. K-324 took advantage of temperature variations in the Gulf Stream. K-324 was in reserve by 1997. The K-324 was written off in 2000 for scrapping.
