The PTF designation was give to 26 boats with four different boat designs. The PTF boats were the Vietnam War "[[brown water]]" river boats version of the World War II [[PT boat]]s. They were heavily armed [[gunboat]]s that were used by the US Navy and by [[Special forces]].<ref name="auto22">{{Cite web|url=https://www.military.com/special-operations/about-the-navy-seals.html|title=Navy SEALs: Background and Brief History|author1=Military com|date=July 17, 2024|website=Military.com}}</ref> The first two PTF boats were commissioned 21 December 1962. The last two PTF were commissioned on 8 April 1968. PFT boats were replaced by the new [[Patrol Craft Fast]] (PCF) boats that were more widely used in Vietnam. There are five PTF boats that have survived and are in various state of restoration. The "Torpedo Boat, Fast" designation is a hold over from World War II, as PTF boats were not equipped with [[torpedo]]es, as they were mostly used in shallow river waters.<ref name="auto3">{{Cite web|url=http://shipbuildinghistory.com/smallships/pt.htm|title=Torpedo Boats PT BPT WWII}}</ref><ref name="auto5">Department of Defense Legacy Resource Management Program, Vietnam War: Special Operation Forces and Warfare Training on U.S. Military Installations, Vietnam Historic Context, Jayne Aaron, LEED AP, Architectural Historian, Steven Christopher Baker, PhD, Historian, February 2020, page 2-36</ref><ref name="auto6">Marolda and Pryce III, Short History of the United States Navy</ref><ref>Charles R.

==History== Following [[World War II]] the [[United States Navy|US Navy]] had little use for [[fast attack craft]], so almost all of the [[PT boat]]s were scrapped at the [[VJ Day|end of the war]] in 1945. PT boats were not needed during the [[Korean War]]. But, as the United States involvement in the Vietnam grew, the Navy saw a need for small combatant boats for the US Navy's "[[brown water]]" river operations.<ref name="auto"/> In 1962, two prototype Korean War PT boats were put back in to service as ''PTF-1'' and ''PTF-2'' .<ref name="auto1">{{Cite web|url=http://www.navsource.net/archives/12/05810.htm|title=PT-810|website=NavSource}}</ref><ref name="auto2">{{Cite web|url=http://www.navsource.net/archives/12/05811.htm|title=PT-811|website=NavSource}}</ref> ''PTF-1'' and ''PTF-2 ''were used by [[US Navy Seals]] for special forces activity. The first SEALs arrived in [[South Vietnam]] in 1962 as advisers to the Vietnamese naval commandos. They trained the commandos in maritime infiltration techniques and counterinsurgency warfare.<ref name="auto5"/><ref name="auto6"/><ref name="auto"/> Due to the immediate need for fast attack river craft, the US Navy looked at boats already in service with other nations. The [[Royal Norwegian Navy]] had built {{HNoMS|Nasty}}, a prototype boat, in 1958 by [[Westermoen Båtbyggeri og Mek Verksted|Westermoen Båtbyggeri]] in [[Mandal, Norway]]. HNoMS ''Nasty'' was designed by Jan Herman Linge. Her prototype boat was of a wooden hull construction. From this boat the Royal Norwegian Navy built a line of 20 {{sclass|Tjeld|patrol boat|0}} patrol boats. Starting on 1 January 1963, the US Navy took delivery of the first Båtbyggeri boats, with designation [[United States Nasty-class patrol boat|''Nasty-class'' patrol boat]]. A total of 14 ''Nasty-class'' patrol boats were built by Båtbyggeri between 1963 and 1965. Båtbyggeri licensed [[John Trumpy & Sons]] in [[Annapolis, Maryland]] to build seven ''Nasty''-class boats in 1968 and 1970. Some parts of the Trumpy boats were imported from Norway, such as the keel and stem. Sewart Seacraft (Swiftships) in [[Berwick, Louisiana]] build four PTF boats of the [[United States Osprey-class patrol boat|''Osprey'' class]] in 1968. The PTF boats were used in Vietnam and operated out of [[Danang, Vietnam]]. The boats operated in the [[Mekong Delta]]. Each PTF boat carried a 12-man team. The PTF boats supplemented the large fleet of aluminum hulled [[Patrol Craft Fast]] (PCF) boats. PTFs were used to carrying out hit-and-run and landing operations. PTFs were also used for [[United States Army]]-Navy-SEAL landing, supply drops, base security patrols, harbor security patrols, intelligence gathering, and rescue operations. In December 1965, the US Navy started [[Operation Game Warden]], in which PTF and PCF boats patrolled the major rivers and canals in the [[Mekong Delta]] and [[Rung Sat Special Zone]].<ref name="Kutler 1996 352">{{cite book|last=Kutler|first=Stanley I.|title=Encyclopedia of the Vietnam War|year=1996|publisher=Charles Scribner's Sons|location=New York|isbn=0-13-276932-8|oclc= 32970270|page=352}}</ref><ref>{{cite book|last=Carhart|first=Tom|title=Battles and Campaigns In Vietnam: 1954-184|year=1984|publisher=Military Press|location=New York|isbn=0-517-425009|oclc=11494209|pages=78–80}}</ref><ref>{{cite book|last=Schreadley|first=R.

==PTF boats== ===Prototype PTF=== The two prototype PTF, ''PTF-1'' and ''PTF-2'' were built for the [[Korean War]] in 1951. Both boats a top speed of over {{convert|40|kn|lk=in}} from the four {{convert|2500|hp|lk=in|adj=on}} [[Packard]] W-100 gasoline engines with shafts. ''PTF-1'' and ''PTF-2'' were armed with two [[Bofors 40 mm gun]]s, two twin [[Oerlikon 20 mm cannon|{{convert|20|mm|2|sp=us|adj=on}} cannon]], one [[M2 Browning|.50-caliber machine gun]], one "Piggyback" [[81 mm mortar]] and one [[Smoke screen|smoke generator]]. Both arrived in Da Nang, Vietnam in April 1964. In 1965 after a year of service, the two PTF Boats were 14 years old, with no spare parts, and outdated, they were replaced by newer PTF and PCF boats. Both boats were removed from service and used as US Navy targets. ''PTC-1'' was sunk off Vietnam and ''PTC-2'' was sunk off the [[Hawaiian Islands]].<ref name="auto3"/><ref name="auto1"/>

===''Nasty'' class=== {{main|United States Nasty-class patrol boat}} The [[United States Nasty-class patrol boat|''Nasty'' class]] were built by two [[shipyard]]s. Wooden hull PTF boats ''PTF-3'', ''PTF-4'', ''PTF-5'', and ''PTF-6'' arrived at Da Nang, Vietnam in May 1964. ''PTF-7'' and ''PTF-8'' arrived at Da Nang in July 1964.
