caption_attribution_description: English: A U.S. Navy North American T-28C Trojan (BuNo 138187) assigned to Naval Air Test Center (NATC) Patuxent River, Maryland (USA), after landing on the aircraft carrier USS Tarawa (CVA-40), in 1955. This aircraft had been built as a standard T-28B without arrester hook, but was obviously fitted with a hook, probably as a prototype for the arrester hook-equipped T-28C.BuNo 138187 was one of two Prototypes that were built as "C" models and was not converted, it was produced at NAA Ingleside Calf plant and flown to NATC for trials.
context_page_description: The North American Aviation T-28 Trojan is a piston-engined military trainer aircraft used by the United States Air Force and United States Navy beginning in the 1950s. Besides its use as a trainer, the T-28 was successfully employed as a counter-insurgency aircraft, primarily during the Vietnam War. It has continued in civilian use as an aerobatics and Warbird performer.
context_section_description: XT-28
  Prototype; two built.
  T-28A
  U.S. Air Force version with an 800 hp (597 kW) Wright R-1300-7 radial engine; 1,194 built.
  T-28B
  U.S. Navy version with 1,425 hp (1,063 kW) Wright R-1820-86A or - 86B radial engine, three-blade propeller, belly-mounted speed brake; 489 built.
  T-28C
  U.S. Navy version, a T-28B with shortened propeller blades and tailhook for carrier-landing training; 266 built.
  T-28D Nomad
  T-28Bs converted for the USAF in 1962 for the counter-insurgency, reconnaissance, search and rescue, and forward air controller roles in Vietnam. Fitted with two underwing hardpoints. The later T-28D-5 had ammo pans inside the wings that could be hooked up to hardpoint-mounted gun pods for a better center of gravity and aerodynamics; 321 converted by Pacific Airmotive (Pac-Aero).
  T-28 Nomad Mark I - Wright R-1820-56S engine (1,300 hp).
  T-28 Nomad Mark II - Wright R-1820-76A (1,425 hp)
  T-28 Nomad Mark III - Wright R-1820-80 (1,535 hp)
  Fairchild AT-28D
  Attack model of the T-28D used for Close Air Support (CAS) missions by the USAF and allied Air Forces in Southeast Asia, which were nicknamed "Tangos" by their pilots. It was fitted with six underwing hardpoints and the rocket-powered Stanley Yankee ejection seat; 72 converted by Fairchild Hiller.
  YAT-28E
  Experimental development of the counter-insurgency T-28D. It was powered by a 2,445 hp (1,823 kW) Lycoming YT-55L-9 turboprop, and armed with two .50 in machine guns and up to 6,000 lb (2,730 kg) of weapons on 12 underwing hardpoints. Three prototypes were converted from T-28As by North American, with the first model flying on 15 February 1963. The project was canceled in 1965.
  T-28S Fennec
  Ex-USAF T-28As converted in 1959 for use by the French Armée de l'Air, replacing the Morane-Saulnier MS.733A. It was flown by their Escadrilles d'Aviation Légère d'Appui (EALA; "Light Aviation Support Squadrons") in the counter insurgency role in North Africa from 1959 to 1962. Fitted with an electrically powered sliding canopy, side-armor, a 1,200 hp Wright R-1820-97 supercharged radial engine (the model used in the B-17 bomber), and four underwing hardpoints. It is referred to as the "S" variant because its engine had a supercharger on it; it has also been referred to as the T-28F variant – with the "F" standing for France.
  For fire support missions it usually carried two double-mount .50-caliber machine gun pods (with 100 rounds per gun) and two MATRA Type 122 6 x 68mm rocket pods. It could also carry on paired hardpoints a 120 kg.[264 lb.] HE or GP "iron" bomb, a MATRA Type 361 36 x 37mm [1.45-inch] rocket pod, a SNEB 7 x 55mm [2.16-inch] rocket pod, or a MATRA Type 13 single-rail, MATRA Type 20 or Type 21 double-rail, MATRA Type 41 quadruple-rail (2 x 2), or MATRA Type 61 or Type 63 sextuple-rail (3 x 3) SERAM T10 heavy rocket launchers. Improvised napalm bombs (called bidons spéciaux, or "special cans") were created by dropping gas tanks loaded with octagel-thickened fuel inside, then later igniting or detonating the spilled fuel with white phosphorus rockets.
  Total 148 airframes bought from Pacific Airmotive (Pac Aero) and modified by Sud-Aviation in France. After the war the French government offered them for sale from 1964 to 1967. They sold most of them to Morocco and Argentina. The Fuerza Aérea de Nicaragua (FAN) purchased four of these ex-Morocco aircraft during 1979. Argentina later sold some to Uruguay and Honduras.
  T-28P
  T-28S Fennec aircraft sold to the Argentinian Navy as carrier-borne attack aircraft. They were given shortened propeller blades and a tailhook to allow carrier landings.
  T-28R Nomair
  An attempt by Hamilton Aircraft Company of Tucson, Arizona to make a civilianized Nomad III-equivalent out of refurbished ex-USAF T-28As. It had a Wright Cyclone R-1820-80 engine to make it fast and powerful, but had to lengthen the wingspan by seven feet to reduce the stall speed to below a "street-legal" 70 knots. The prototype flew for the first time in September, 1960, and the FAA Type Certificate was received on 15 February 1962. At the time, the T-28-R2 was the fastest s
