Eighty feet long, built of layered mahogany and powered by three monstrous 1500-horsepower V-12 engines, the US Navy's Patrol Torpedo (PT) boats screamed across the water at over forty knots. They were not only fast, but also armed to the teeth, bristling with a deadly array of machine guns, automatic cannons, torpedoes, and depth charges. Duty aboard the boats was often reserved for the spirited, the aggressive, and the very young, the average age of a PT sailor being twenty-four years of age. The "mosquito boats" carried out a variety of missions during the war, including scouting and reconnaissance, attacking enemy shipping, search and rescue, interdiction of supply routes, strafing of enemy shore installations, supporting coast watchers and special operations forces, and even putting armed crew members ashore to perform commando-style raids on far-flung enemy outposts.
