Frigate
BRP Rajah Humabon (PF-11) (ex-USN USS Atherton DE-169)
Datu Kalantiaw Class (USN Cannon Class)
"Cannon-class destroyer escort"
The Cannon class destroyer escorts were built primarily for ocean Anti-Submarine Warfare escort service during World War II. The lead ship, USS Cannon (DE-99) was commissioned on 26 September 1943 at Wilmington, Delaware. The class was also known as the DET type from their Diesel Electric Tandem drive[1]. Of the 116 ships ordered 44 were cancelled and 6 commissioned directly into the Free French Forces. Destroyer escorts were regular companions escorting the vulnerable cargo ships.
BRP Rajah Humabon (PF-11) of the Philippine Navy, formerly the USS Atherton (DE-169) remains as the only confirmed commissioned ship of this class as of 2010.
USS Atherton (DE-169), a Cannon-class destroyer escort, was the only ship of the United States Navy to be named for Lt. (jg) John McDougal Atherton, who died when the USS Meredith sank near Guadalcanal during World War II.
Atherton (DE-169) was laid down on 14 January 1943 at Newark, New Jersey, by the Federal Drydock & Shipbuilding Co.; launched on 27 May 1943; sponsored by Mrs. Cornelia A. Atherton, the mother of Lt. (jg.) Atherton; completed at the Norfolk Navy Yard; and commissioned there on 29 August 1943, Lt. Comdr. Paul L. Mansell, Jr., USNR, in command.
Service history
Atherton began shakedown in September. During this time, conducted exercises in Chesapeake Bay and made two cruises to Bermuda. On 13 November, she got underway for Puerto Rico. Upon her arrival there, the destroyer escort assumed anti-submarine warfare (ASW) patrol duties in waters between St. Croix, Virgin Islands, and the Anegada Passage. On 24 November, she attacked a submarine contact, but observed no evidence of damage. The ship was relieved three days later and returned to Norfolk on 30 November. There, she began making daily cruises in Chesapeake Bay to train prospective crew members for destroyer escorts. Atherton left Norfolk on 11 December to escort a convoy bound for the Panama Canal but was back in Hampton Roads on 27 December.
From January 1944 to May 1945, Atherton operated under the control of Task Force 62 on escort duty for transatlantic convoys. She escorted convoys from Norfolk and New York City to various ports in the Mediterranean. These ports included Casablanca, Morocco; Bizerte, Tunisia; and Oran, Algeria. Atherton periodically reported to the Boston Navy Yard for overhaul. On 9 May 1945, while en route from New York to Boston, Atherton encountered a U-boat. After four depth charge attacks, pieces of broken wood, cork, mattresses, and an oil slick broke the surface. Atherton, in conjunction with Moberly (PF-63), was later credited with destroying the German submarine U-853.
On 28 May, Atherton sailed for Guantanamo Bay, Cuba. She arrived on 1 June and held a week of exercises with Escort Division 13 before sailing on 6 June for the Pacific. Proceeding via the Panama Canal and San Diego, Atherton arrived at Pearl Harbor on 29 June. There, the ship underwent a tender availability and carried out a series of exercises before getting underway on 15 July for the Marianas. She reached Saipan on 26 July and conducted antisubmarine patrols off Saipan. On 5 August, she got underway for Ulithi, where she operated on picket station until 18 August. Between 19 August and 16 September, Atherton made two round-trip voyages escorting convoys to Okinawa. She was then assigned to rescue station duties out of Saipan which lasted through the end of the war.
On 1 November, Atherton headed back toward the United States. After stops at Pearl Harbor and San Diego, she transited the Panama Canal and arrived at Jacksonville, Florida, in December. On 10 December 1945, she was decommissioned and placed in reserve at Green Cove Springs, Florida. On 14 June 1955, Atherton was transferred to Japan; and, her name was struck from the Navy list.
Awards
Atherton was awarded one battle star for her World War II service. Crew members of the USS Atherton DE 169 received a bronze star in the American Theater ribbon for their action in the sinking of the last German submarine of World War II in American Waters. The battle took place shortly after the U-853 had torpoedoed the Boston Collier "Black Point" at 5:40PM, May 5, 1945 (just a few hours before VE Day). The Atherton tracked down the U-853 just eight miles off Block Island, RI sinking her in just 100 feet of water. The next day divers were sent down, confirming the only sinking of a sub with the newly developed "Hedge Hogs."
