The U.S. Navy has also been involved in search and rescue/search and salvage operations, sometimes in conjunction with vessels of other countries as well as with U.S. Coast Guard ships. Two examples are the 1966 Palomares B-52 crash incident and the subsequent search for missing hydrogen bombs, and Task Force 71 of the Seventh Fleet's operation in search for Korean Air Lines Flight 007, shot down by the Soviets on 1 September 1983.
