[USS *Flagstaff*](/source/USS_Flagstaff) and *PTF-23* in 1974

**PTF boat**, (short for **Patrol Torpedo, Fast**) are fast [United States Navy](/source/United_States_Navy) [patrol boats](/source/Patrol_boat) introduced in the early part of the [Vietnam War](/source/Vietnam_War). The PTF designation was give to 26 boats with four different boat designs. The PTF boats were the Vietnam War "[brown water](/source/Brown_water)" river boats version of the World War II [PT boats](/source/PT_boat). They were heavily armed [gunboats](/source/Gunboat) that were used by the US Navy and by [Special forces](/source/Special_forces).[3] 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](/source/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 [torpedoes](/source/Torpedo), as they were mostly used in shallow river waters.[4][5][6][7]

## History

Following [World War II](/source/World_War_II) the [US Navy](/source/United_States_Navy) had little use for [fast attack craft](/source/Fast_attack_craft), so almost all of the [PT boats](/source/PT_boat) were scrapped at the [end of the war](/source/VJ_Day) in 1945. PT boats were not needed during the [Korean War](/source/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](/source/Brown_water)" river operations.[8] In 1962, two prototype Korean War PT boats were put back in to service as *PTF-1* and *PTF-2* .[9][10] *PTF-1* and *PTF-2*were used by [US Navy Seals](/source/US_Navy_Seals) for special forces activity. The first SEALs arrived in [South Vietnam](/source/South_Vietnam) in 1962 as advisers to the Vietnamese naval commandos. They trained the commandos in maritime infiltration techniques and counterinsurgency warfare.[5][6][8] 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](/source/Royal_Norwegian_Navy) had built [HNoMS *Nasty*](/source/HNoMS_Nasty), a prototype boat, in 1958 by [Westermoen Båtbyggeri](/source/Westermoen_B%C3%A5tbyggeri_og_Mek_Verksted) in [Mandal, Norway](/source/Mandal%2C_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 [*Tjeld*-class](/source/Tjeld-class_patrol_boat) patrol boats. Starting on 1 January 1963, the US Navy took delivery of the first Båtbyggeri boats, with designation [*Nasty-class* patrol boat](/source/United_States_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](/source/John_Trumpy_%26_Sons) in [Annapolis, Maryland](/source/Annapolis%2C_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](/source/Berwick%2C_Louisiana) build four PTF boats of the [*Osprey* class](/source/United_States_Osprey-class_patrol_boat) in 1968. The PTF boats were used in Vietnam and operated out of [Danang, Vietnam](/source/Danang%2C_Vietnam). The boats operated in the [Mekong Delta](/source/Mekong_Delta). Each PTF boat carried a 12-man team. The PTF boats supplemented the large fleet of aluminum hulled [Patrol Craft Fast](/source/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](/source/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](/source/Operation_Game_Warden), in which PTF and PCF boats patrolled the major rivers and canals in the [Mekong Delta](/source/Mekong_Delta) and [Rung Sat Special Zone](/source/Rung_Sat_Special_Zone).[11][12][13] Most US Navy crews and [United States Marine Corps](/source/United_States_Marine_Corps) underwent PTF training at the [Naval Amphibious Base Coronado](/source/Naval_Amphibious_Base_Coronado).[14][5][6] PTF were used by CSS Intelligence Department and Tactical Operations Department, founded April 1, 1964, that were stationed at Lower Base in Tien Sa. CSS also founded two camps: Phoenix va DoDo at [Cu Lao Cham](/source/Cu_Lao_Cham_Marine_Park) (Paradise Island). The PTF boats at these camps were from Vietnamese Navy headquarters.[15] [Mobile Support Teams](/source/Mobile_Riverine_Force) provided combat craft support for SEAL operations, as did [Patrol Boat, River](/source/Patrol_Boat%2C_River) and [Swift Boat](/source/Swift_Boats) sailors. In February 1964, Boat Support Unit One was founded under Naval Operations Support Group, Pacific. Boat Support Unit One crews operated the PTF boat program. Boat Support Unit Two was formed later, both were later renamed Coastal River Squadron 1 and 2.[6][16] Boat Support Unit One supported the Navy Special Warfare forces in Vietnam. In 1965, Boat Support Squadron One started training PFT and PCF crews for Vietnamese coastal patrol and interdiction operations.[17] In January 1963, US Navy [Seabee](/source/Seabee) (Navy Construction Battalion) arrived [South Vietnam](/source/South_Vietnam) to build support bases. Seabees built a PFT and PCF base, also a vast support base at [Da Nang](/source/Da_Nang) and [Saigon](/source/Saigon). These bases support the US Navy, and Marine Corps forces, also some Air Force units and some Army units. PFT noted raids were on [Đồng Hới](/source/%C4%90%E1%BB%93ng_H%E1%BB%9Bi), [Yên Phú](/source/Y%C3%AAn_Ph%C3%BA%2C_H%C3%A0_Giang) and [Sầm Sơn](/source/S%E1%BA%A7m_S%C6%A1n) radar sites, [Phuc Loi](/source/Ph%C3%BAc_L%E1%BB%99c%2C_B%E1%BA%AFc_K%E1%BA%A1n), and [Tiger Island](/source/C%E1%BB%93n_C%E1%BB%8F_district). The PTF raids ended in 1971. The PTF boats were taken to [U.S. Naval Base Subic Bay](/source/U.S._Naval_Base_Subic_Bay) and formed the [MST-3](/source/Marine_Science_Technician) unit in 1972. The PTF boats were taken out of service in 1976 and 1978, with *PTF-13* removed in 1972.[18][8][5][6]

## PTF boats

### Prototype PTF

The two prototype PTF, *PTF-1* and *PTF-2* were built for the [Korean War](/source/Korean_War) in 1951. Both boats a top speed of over 40 [knots](/source/Knot_(unit)) (74 km/h; 46 mph) from the four 2,500-[horsepower](/source/Horsepower) (1,900 kW) [Packard](/source/Packard) W-100 gasoline engines with shafts. *PTF-1* and *PTF-2* were armed with two [Bofors 40 mm guns](/source/Bofors_40_mm_gun), two twin [20-millimeter (0.79 in) cannon](/source/Oerlikon_20_mm_cannon), one [.50-caliber machine gun](/source/M2_Browning), one "Piggyback" [81 mm mortar](/source/81_mm_mortar) and one [smoke generator](/source/Smoke_screen). 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](/source/Hawaiian_Islands).[4][9]

- *PTF-1* was built by [Bath Iron Works](/source/Bath_Iron_Works) in [Bath, Maine](/source/Bath%2C_Maine) in 1951 as *PT-810*. *PTF-1* had a light displacement of 90 [long tons](/source/Long_ton) (91 t), length of 89 ft 0 in (27.13 m), beam of 24 ft 1 in (7.34 m), and draft of 5 ft 9 in (1.75 m). She was put in service on 24 November 1951 and was struck from the Naval Register 1 November 1959. She was reactivated on 21 December 1962. *PTF 1* was sunk as a target in 1965.[9][4][10]

- *PTF-2* was built by [Trumpy & Sons](/source/John_Trumpy_%26_Sons) in [Annapolis, Maryland](/source/Annapolis%2C_Maryland) in 1951 as *PT-811*. *PTF-2* had a light displacement of 94 [long tons](/source/Long_ton) (96 t), and length of 94 ft 0 in (28.65 m), beam of 24 ft 11 in (7.59 m), and draft of 4 ft 2 in (1.27 m). She was put in service on 6 March 1951 and was struck from the Naval Register 1 November 1959. She was reactivated on 21 December 1962. *PTF-2* was sunk as a target in 1965.[10][4]

### *Nasty* class

Main article: [United States Nasty-class patrol boat](/source/United_States_Nasty-class_patrol_boat)

The [*Nasty* class](/source/United_States_Nasty-class_patrol_boat) were built by two [shipyards](/source/Shipyard). 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. The *Nasty*-class boats have a displacement of 80 long tons (81 t), a length of 80 ft 4 in (24.49 m), a beam of 24 ft 7 in (7.49 m) and a draft of 3 ft 10 in (1.17 m). Power is derived from two [Napier Deltic](/source/Napier_Deltic) Turboblown [diesel engines](/source/Diesel_engine) with total of 6,200 brake horsepower (4,600 kW) and a top speed of 38 [knots](/source/Knot_(unit)) (70 km/h; 44 mph). The Napier Deltic engines were built in England.[19][4]

#### Båtbyggeri

[Westermoen Båtbyggeri og Mek Verksted](/source/Westermoen_B%C3%A5tbyggeri_og_Mek_Verksted), also called [A/S Båtservice](/source/A%2FS_B%C3%A5tservice) in the [Westermoen Hydrofoil shipyard](/source/Westermoen_Hydrofoil) in [Mandal, Norway](/source/Mandal%2C_Norway) built 14 *Nasty*-class patrol boats: *PTF-3* to *PTF-16*.[4][19][20]

#### John Trumpy & Sons

John Trumpy & Sons of Annapolis, Maryland built six *Nasty*-class patrol boats: *PTF-17* to *PTF-21*, under license from Båtservice.[4][19][20]

### *Osprey* class

The *Osprey*-class PTF boats were built by [Sewart Seacraft](/source/Sewart_Seacraft) (now Swiftships). Sewart Seacraft built four of the new 3⁄8-inch (9.5 mm) aluminum alloy hull boats: PTF boats: [*PTF-23*](#Surviving_boats) through *PTF-26*. Sewart Seacraft was a division of [Teledyne Inc.](/source/Teledyne_Technologies). The chief designer of the 95-foot (29 m) *Osprey*-class patrol boat was Kenneth Hidalgo. *Osprey*-class boats have a displacement of 80 long tons (81 t), a length of 94.5 ft (28.8 m), a beam of 24.5 ft (7.5 m) and a draft of 6.8 ft (2.1 m). The *Osprey* class is powered by two 18-cylinder Napier Deltic diesel engines. Each engine creates 3,100 horsepower (2,300 kW) and were constructed by D. Napier & Son Ltd. of England. The *Osprey*-class boats have an empty displacement of 150,930 lb (68,460 kg).[4][21][22][23]

- *PTF-23* is now a [research vessel](/source/Research_vessel) and diving platform, renamed RV *Osprey* in [St. Augustine, Florida](/source/St._Augustine%2C_Florida) with twin Detroit 12v71 and fuel capacity of 6,281 US gallons (23,780 L; 5,230 imp gal). *PTF-23* is now heavily modified. For a time she was named RV *Angel Lauren* as a research vessel. The *PTF-23* was refitted in 2002 by TLG of [Miami, Florida](/source/Miami%2C_Florida), then used for treasure surveys until 2004. In 2011 the vessel was used in the Dominican Republic by Anchor Research & Salvage.[21][22][23]

- *PTF-24* was sunk as a target 1985 by the US Navy off San Diego, after working with a water jet propulsion conversion testing in the Osprey990 Program with [*Pegasus*-class](/source/Pegasus-class_hydrofoil) [hydrofoils](/source/Hydrofoil). *PTF-24* served in Vietnam until 1976. In July 1976 she ran aground off [San Clemente Island](/source/San_Clemente_Island), California.[8][24]

- *PTF-25* was sunk as a target in 1979 by the US Navy, in Pemblico Sound near [Marine Corps Air Station Cherry Point](/source/Marine_Corps_Air_Station_Cherry_Point), [North Carolina](/source/North_Carolina) at the BT-11 target range-Piney Island Range for [USMC](/source/United_States_Marine_Corps) pilot training. *PTF-2*5 was modified to look like a [Komar-class missile boat](/source/Komar-class_missile_boat). The vessel was sank as a target at [35°01′37″N 76°27′39″W / 35.026917°N 76.460944°W / 35.026917; -76.460944](https://geohack.toolforge.org/geohack.php?pagename=PTF_boat&params=35.026917_N_76.460944_W_). *PTF-25* operated in Vietnam until 1979.[8][25]
