The OSP Navy idea as a branch of the PA is the brainchild of MacArthur and Eisenhower who immediately asked the USN if they can help. The USN have no motor torpedo boat program but the British and Italian Navies have. A deal was made with Thornycroft Inc. of England that sold us two Motor Torpedo Boats (MTB) we identified as Q-111 and Q-112. Why it was called Q-Boats was never explained but I think, MacArthur who is a good friend and compadre of Quezon did it to titillate the ego of his compadre. MacArthur’s only son, Arthur, is the godson of Quezon.
Q-111 is 65 ft. long 15 ft. wide with 3-12 cylinder 3,000 hp engines while Q-112 is 55 ft. long 11 ft. wide with 2-12 cyl. 3,000 hp engines. Both has cruising engines with mufflers that run like a car; 2 torpedoes, 2 depth charge throwers, and 3 .50 Cal AA Guns. Both makes, over 55 knots.
USN promise to develop their own at Quonset Point, R.I. which they called Patrol Torpedo (PT) Boats.
