The USS Bonita (SSK-3/SS-552) was a Barracuda-class submarine of the United States Navy, originally named USS K-3. Laid down on May 19, 1950, at Mare Island Naval Shipyard in California, her keel was established during construction, and she was launched on June 21, 1951. Mrs. J.S. Clark sponsored the vessel, commemorating her late husband, Commander James S. Clark. The submarine was commissioned on January 11, 1952, and served primarily in experimental and anti-submarine warfare (ASW) roles. As part of Project Kayo, K-3 was equipped with a large BQR-4 bow-mounted sonar array designed for passive acoustics, which enhanced detection capabilities against snorkeling submarines. These technological advancements proved crucial in developing tactics for nuclear-powered submarines, despite the vessel’s limited speed and periodic need to snorkel for battery recharge. The K-3 joined Submarine Squadron 7 at Pearl Harbor in May 1952, where it conducted experimental duties focused on ASW tactics. In December 1955, she was renamed USS Bonita. The vessel participated in various operations, including a cruise to Alaskan waters in 1956 and reassignment to Submarine Squadron 5 in San Diego in 1957 for ASW training. She underwent overhaul in late 1957 and early 1958, updating her electronics systems. During 1958, as the Soviet threat shifted toward nuclear submarines, the Bonita was withdrawn from her SSK role and used as a target for nuclear weapons testing at Eniwetok during Operation Hardtack I, serving as a shock test target in April–June 1958; the damage inflicted was minimal and primarily affected electronics. The USS Bonita was decommissioned on November 7, 1958, and redesignated SS-552 in August 1959. She remained on the Naval Register until April 1, 1965, and was sold for scrap in November 1966. Her service contributed significantly to early submarine sonar development and anti-submarine tactics during the Cold War era.
