Caption at original URL:  On May 11, 1962, Razorback participated in the "SWORDFISH" nuclear weapons test. An ASROC with a nuclear depth charge warhead was fired by the destroyer Agerholmn (DD 826) at a target raft from a range of 2 nautical miles. Razorback was submerged at periscope depth 2 nautical miles from the target raft. The ASROC weapon produced a powerful underwater shock wave which visibly shook Razorback and her crew. The resulting data was used to formulate tactical doctrine for ASROC, a weapon that remained in front-line service for nearly 30 years.
