USS Callaghan (DD/DDG-994) was the second ship of the Kidd class of destroyers operated by the U.S. Navy. Derived from the Spruance class, these vessels were designed for air defense in hot weather. She was named for Rear Admiral Daniel J. Callaghan, who was killed in action aboard his flagship, the heavy cruiser San Francisco, during the Naval Battle of Guadalcanal on 13 November 1942.

Originally to be named Daryush, the ship was ordered by the Shah of Iran, but was undelivered when the 1979 Iranian Revolution occurred. Subsequent to this, the U.S. Navy elected to commission her and her sister ships for service in the Persian Gulf and Mediterranean Sea, as they were equipped with heavy-duty air conditioning and were also well suited to filtering sand and the NBC warfare contaminants.

She was commissioned in 1981, and home ported in San Diego, California at NAS North Island.

On 1 September 1983 Callaghan was on deployment to the Western Pacific, and making a port visit in Sasebo, Japan. Korean Air Lines Flight 007, on its way from Anchorage, Alaska to Seoul, Korea, carrying 269 passengers and crew, strayed into Soviet airspace. A Soviet Sukhoi Su-15 fighter jet was sent up to destroy the intruding Boeing 747. After the attack, the Callaghan's crew was recalled and sent to search for survivors. During its survey of the crash site, the Callaghan was under very close scrutiny of the Soviet Navy, narrowly avoiding open conflict while engaged in their search. No survivors were found. The Callaghan received a Meritorious Unit Citation from the U.S. Navy and a special citation from the South Korean government for its role in the mission.
