PTF-26, "Liberty", was the last PTF built. PTFs, Fast Patrol Boats, were the Vietnam War version of the famous WW II PT Boats. They were heavily armed near-coastal gunboats, used mostly by Special Forces. PTF-26 is also the last of only four Osprey-Class PTFs, the bigger, aluminum-hulled brother to the Nasty-Class boats. She was powered by twin T-1837K Napier Deltic engines. These exotic diesels put out 3100 HP each using 3 crankshafts, 18 cylinders and 36 pistons. During a 1970s speed run PTF-26 was clocked at 51 knots! PTF-26 currently serves as both an operational museum and a youth training vessel.
