Year(Laid Down/First Commissioned/Commissioned in PN):

Program:
The DEs were built after the fashion of American fleet destroyers, having a long flush deck with a prominent sheer line in place of the more commodious long forecastle decks preferred by the British. Far more emphasis was placed on gun armament, with superimposed 76.2 mm (3") guns forward, a single aft and numerous guntubs with a mixture of close-range weaponry, mostly single 20 mm guns, Hedgehog was sited forward. The Buckley class (152 ships) have turbo-electric diesel engines. As anti-submarine ships the DEs were very effective, while many went on after the war to be converted into fast transports (APD) or radar-pickets (DER). DE 637, first commissioned on 27 January 1944, reclassified as APD 40 on 25 June 1945, decommissioned 18 December 1958, sold to Philippines 21 April 1961, sunk during a typhoon at Bataan National Shipyard, June 1962, raised in December 1964, broken up for scrap in 1966.

Both ships sold as scrap to Ming Hing & Co., Kowloon, Hong Kong, for $26,100 and $21,100 respectively on 8 July 1977.
Structure: Wooden hulls, with non-magnetic, stainless-steel machinery. Originally designed to carry a 40 mm bow gun, but was replaced by the twin 20 mm later. All remaining USN Agile class were modernized in 1968, with the SQQ-14 minehunting sonar replaceing the UQS-1 and 40 mm mount was replaced to make space for the hoist machinery for the sonar. Bridge structure for command and control were built up, new communications and upgraded communications. PM 91 and PM 92 retained their original engines though. Both were later returned to the USN after having their wooden hulls deteriorate under PN operation.

Year(Commissioned in OSP):
Q 111 July 1939; Q 112 March 1939; Q 113 1940
Program:
The first Q-boat Q 112, was a standard inter-war 55-foot stepped-hull Thornycroft MTB with aftward launch torpedo chutes and was named 'Abra'. Laid down on 14 April 1938, arrived on March 1939. The second arrived in July 1939, named 'Luzon', Q 111. The third MTB's hull was locally built by Engineer Island and had imported Thornycroft Inc. engine. Completed in March 1941, she was named 'Agusan', Q 113. Eight other Q-boats were laid down on May 1941, from which only two (Q 114 and Q 115) were commissioned in early 1942 (probably, not fully completed). Six incomplete boats were destroyed by Japanese aircraft on slipways during bombings in December, 1941. They were to be part of the 50 MTBs envisioned then to be completed by 1946. During this time only the British and the Italian navies have MTBs while the USN was developing their own, called PT boats. Q-boats were so called in honor of Pres. Quezon. They were assigned to the OSP's 1st Q-Boat Squadron, also dubbed as the 'Mosquito Fleet', which won a lot of decorations and citations during its colorful stint in WW II.
