USS Oyster Bay (AGP-6), originally and later AVP-28, was a United States Navy motor torpedo boat tender in commission from 1943 to 1946. She saw service in World War II.

From 1957 to 1993, the former Oyster Bay served in the Italian Navy as the special forces tender Pietro Cavezzale (A 5301).

Construction, commissioning, and shakedown

Oyster Bay was laid down as a

Barnegat-class small seaplane tender designated AVP-28 at Lake Washington Shipyard, Houghton Washington, on April 17, 1942, and was launched on September 7, 1942, sponsored by Mrs. William K. Harrill. On May 1, 1943, she was reclassified as a motor torpedo tender and redesignated AGP–6 and, accordingly, completed to a modified design to allow her to fulfill this new role. She was commissioned

on November 17, 1943.

Oyster Bay departed Seattle, Washington, on December 7, 1943, for shakedown at San Diego, California, which lasted for the remainder of 1943.

World War II service

New Guinea campaign

Oyster Bay got underway from San Diego on January 2, 1944, steaming to

patrol torpedo boats (PT boats) to Seeadler Harbor in the Admiralty Islands

.

The spring of 1944 was an active one for Oyster Bay. On March 14, 1944, she bombarded the Japanese shore installations on Pityilu Island in support of the United States Army. On March 20, 1944, she was underway for Langemak, New Guinea, with 42 wounded soldiers for evacuation to Base Hospital, Finschhafen, New Guinea. After returning to Seeadler Harbor on March 31, 1944, she bombarded Ndrilo Island to the east of Seeadler Harbor preparatory to the landing there by U.S. Army ground forces.

Oyster Bay shifted to

Dreger Harbor on April 19, 1944. Allied forces moved on Aitape on April 22, 1944, and on April 24, 1944, two days after the landings at Aitape, Oyster Bay departed for the area with 15 PT boats. Japanese planes attacked the convoy

on April 27, 1944, but, while one PT boat was hit, Oyster Bay escaped damage.

In May 1944, Oyster Bay proceeded to

airstrip. Later in June 1944, Oyster Bay bombarded shore installations on the Wicki River and at Samar Village

, preparatory to U.S. Army attacks.

Leaving Mios Woendi Island on July 12, 1944, Oyster Bay reported to Brisbane for shipyard availability. A British Royal Air Force plane struck the top of the ship's mast, carried away her antennae and damaged her navigation lights on July 22, 1944, but hasty repairs permitted Oyster Bay to depart for Mios Woendi on August 16, 1944.

Philippines campaign

Oyster Bay then steamed on to

fighters

dived on Oyster Bay on the November 26, 1944, but intense antiaircraft fire shot them both down.

In January 1945, Oyster Bay got underway for Hollandia, then returned to Leyte Gulf for motor torpedo boat tender operations on February 8, 1945. Departing for the invasion of

Tawi Tawi, where she continued motor torpedo boat tender operations until she returned to Guinan Harbor

on August 6, 1945.
