The first and second naval vessels named Somerset retained the name carried at the time of their acquisition by the Navy during the Civil War and World War I, respectively, while the third Somerset (LPD-25) was named to honor Somerset County, Pa., where United Air Lines Flight 93 crashed on 11 September 2001. On that day, a seven-member flight crew and the 33 passengers were on board when the aircraft was hijacked by al Qaeda-linked suicide terrorists. Those on board the doomed plane, however, bravely attempted to wrest control of the aircraft from the four hijackers, and Flight 93 crashed in Stonycreek Township, well short of what most believed was a prominent target in Washington, D.C. "The courage and heroism of the people [on]board the flight will never be forgotten,” Secretary of the Navy Gordon R. England declared, “and USS Somerset will leave a legacy that will never be forgotten by those wishing to do harm to this country."
Somerset (AK-212) and Somerset (PCE-892) were named for the counties in Maryland, Maine, New Jersey, and Pennsylvania, but the former was never commissioned, and the latter received her name while decommissioned and in reserve, and thus never operated under that name.
Somerset (AK-212) was laid down under a Maritime Commission contract (MC Hull No. 2166) on 9 October 1944 at Sturgeon Bay, Wis., by the Leathem D. Smith Shipbuilding Co.; launched on 21 January 1945; and sponsored by Mrs. Fred Bradley. Initially earmarked to be manned by a U.S. Coast Guard crew, Somerset was completed at her building yard on 19 February 1945. After she successfully completed her Maritime Commission acceptance trials, a Navy sub-board of inspection and survey recommended preliminary acceptance on 22 February 1945.
Broken-down for the voyage via inland waterways, the ship arrived at New Orleans, La., on 2 May 1945 to be transferred to Pendleton Shipyards at New Orleans for reassembly. Accepted by the Navy on 20 September 1945 within a month of the Japanese surrender, Somerset began the conversion process to a cargo ship on 24 September. Ironically, her prospective commanding officer reported on 28 September that progress of the work was proceeding satisfactorily and that crew deficiencies caused by demobilization had been corrected, when, that same day [28 September] the ship was earmarked for return to the Maritime Commission. Her assignment to the Pacific Fleet was cancelled on 29 September. Her estimated commissioning date had been 15 October. Redelivered to the War Shipping Administration (WSA) at 1500 on 2 November 1945, Somerset was stricken from the Navy Register on 5 December 1945 never having been commissioned.
On the same day the WSA received the cargo vessel, renamed Coastal Sentry, that agency transferred her to the Stockard Steamship Company at New Orleans. Transferred again, to the War Department, on 2 August 1946 at Baltimore, Md., the ship entered the Reserve Fleet, berthed at Suisun Bay, Ca., on 28 September 1949, with the Army retaining her title. On 12 December 1949, however, Coastal Sentry was declared surplus.
The ship resumed commercial operation under the house flag of the Matson Navigation Company on 15 November 1951. Returned to the Reserve Fleet, this time at Astoria, Ore., on 17 February 1954, Coastal Sentry was taken out of reserve status on 10 May 1955 to be operated by the West Coast Trans-Oceanic Steamship Line for the Military Sea Transportation Service (MSTS). Another stint of inactivity followed (19 October 1955-22 May 1956), after which she again served under MSTS, this time with the Coastwise Line.
Placed in reserve at Olympia, Wa., on 28 September 1956, Coastal Sentry was taken out of the Reserve Fleet on 29 March 1957. Retaining her name, she was operated by the U.S. Air Force as a missile range instrumentation ship (AGM). Reacquired by the Navy on 1 July 1964 and reinstated on the Naval Vessel Register, Coastal Sentry was designated as T-AGM 15.
Along with Rose Knot (T-AGM-14), Coastal Sentry not only collected and relayed radio telemetry information from on board spacecraft, but operated in the command-control role, having embarked National Aeronautics and Space Administration (NASA) flight controllers. As an example of that work, Coastal Sentry initiated the necessary re-entry command signals on the Gemini VIII mission when the capsule had to make an emergency landing in the Pacific on 17 March 1966.Transferred to the Maritime Administration (the successor of the Maritime Commission) on 11 July 1968, the ship was delivered the same day to the firm of Fuji Marden and Co., Ltd., of Hong Kong, British Crown Colony, at Fremantle, Australia, for scrapping. Coastal Sentry (T-AGM-15) was stricken from the Naval Vessel Register on 9 October 1969.
