Q-111 Luzon was a motor torpedo boat of the United States Army during World War II as part of the Offshore Patrol based at Manila.


In 1935, the Commonwealth Government passed the National Defense Act. The Act was criticized because it did not include funding for a Commonwealth navy instead relying on the United States Asiatic Fleet.[2] Determined to develop an indigenous naval defense, the government authorized the creation of its own naval patrol unit consisting of a squadron of three wooden-hull, fast patrol torpedo boats[3] with the goal to reach 36 boats by 1946.[4] To avoid overlap with the Asiatic Fleet, the unit was to be part of a new seagoing arm of the Philippine Army[5] under the United States Army Forces in the Far East. On 9 February 1939, the Off Shore Patrol (OSP) was formed with its headquarters located at Muelle Del Codo, in the Port of Manila and was headed by U.S. Naval Academy graduate First Lieutenant Jose V. Andrada[5] (namesake of the Jose Andrada-class patrol craft). The first two boats, the 65 foot Q-111 Luzon and the 55 foot Q-112 Abra were ordered simultaneously from the British builder John I. Thornycroft & Company of Southampton based on their existing coastal motor boat design.[6][7][8]

Q-111 differed in that she was larger and had fixed deck torpedo tubes while Q-112 had two torpedoes in stern troughs.[6][3] She was laid down on April 15, 1938; completed trials in April 1939; and arrived in the Philippines in June 1939.[6] With the arrival of locally-made Q-113 Agusan, the squadron was complete with Q-111 serving as the squadron's flagship.[4] The torpedo boats were based at Cavite Naval Base but berthed with maintenance facilities at Muele del Codo (Engineer Island) in the port area of Manila.[4] In 1941, the squadron conducted joint maneuvers in Manila Bay with the 6 boats of Motor Torpedo Boat Squadron Three (PT-31, PT-32, PT-33, PT-34, PT-35, PT-41) commanded by Lt. John D. Bulkeley.[9] On December 4, 1941, Enrique L. “Henry” Jurado, a 1934 graduate of the U.S. Naval Academy was put in charge of the squadron.[9] After the Attack on Pearl Harbor, the squadron added two additional boats, converted launches that served as patrol boats, the Q-114 Danday (ex-Carmen, named after the wife of Jurado) and the Q-115 Baler (former tender of the presidential yacht BRP Banahaw (ex-Casiana, ex-Cassandra).[10][11] The squadron patrolled the waters of the bay and protected the eastern shore of the Bataan Peninsula from Japanese infiltration.[4] After Manila was declared an open city on 26 December 1941, the squadron operated out of Sisiman Cove[1], to the immediate east of Cavite and north of Corregidor where the American PT boats were also based.[4] The squadron along with its American counterparts, were serviced by the submarine tender, Canopus which was moored at Cavite Naval Base. In addition to conducting patrols, Q-111 delivered food, ammunition, troops, and medicine to the beleaguered troops during the Battle of Bataan and Battle of Corregidor.[4]

On January 17, 1942, Q-111 and Q-112 were patrolling off the east coast of Bataan when they were attacked by nine Japanese dive bombers.[4] The Q-boats successfully evaded the bomb attack and were able to shoot down or severely damage three attacking aircraft with their machine guns.[4][12] Two officers of the Q-111 were awarded medals: Captain Alberto Navarrete received the Distinguished Conduct Star; and Lieutenant Heracleo Alano received the Silver Star.[4][10] On 8 April 1942, after the Japanese occupation of Manila and the fall of Bataan left the squadron without a safe port, it was decided to attempt to attempt to make an escape to Australia with the remaining 4 boats of the squadron (Danday had been bombed and destroyed on February 2).[10][13] Q-112 developed engine troubles and had to return where it was scuttled at Navotas on 9 April 1942.[10] The remainder of the squadron was first intercepted by Japanese land-based Naval aircraft of the 1st Kōkūtai and were able to down one plane; and then by the Japanese destroyers Samidare and Murasame.[10] The squadron attacked the destroyers with their torpedoes and machine gun fire but did not score any hits.[10] Q-111 was hit and scuttled by its crew somewhere between Batangas and Cavite provinces on 9 April 1942.[10] Q-113 and Q-115 returned to the safety of the bay where Q-113 was scuttled on 9 April 1942 to prevent Japanese capture.[10] Q-115 was ultimately able to leave the bay with 23 passengers but was captured by the Japanese off Cabra Island.[10]

Q-111 was re-floated, rebuilt, and commissioned into service on 12 April 1943 by the Imperial Japanese Navy as Patrol Boat No. 114.[10][14] In 1944 or 1945, she was sunk by US Naval aircraft in the Philippines.[10]
