The main reason for the different engine was the wish of the Navy to use an engine it already used. The NJ-1 were not armed and had no tail-hooks. They had dual short exhausts under the front cowling.⁽¹³²⁹⁾

Retained rounded wingtips and rounded rudder of the BT-9. Wirraways were even used as interceptors and fighter-bombers. A Wirraway was the only T-6 variant credited with an air kill: On December 26th, 1942 John Archer and N.J.Muir of No 4 Army Cooperation Sqn with Wirraway A20-103 shot down a lonely Zero.⁽¹³²⁹⁾ According to other sources⁽¹³³⁰⁾ it probably was not a Zero, but a Nakajima Ki-43 Oscar of the Japanese Army's recently- arrived 11th Sentai. Very likely, the Japanese pilot had himself mistaken the RAAF machine for a Zero. For his singular success, Archer was awarded the Silver Star by the Americans. Wirraway A20-103 is now on display at the Australian War Memorial.

The NA-44 was the prototype of a series of light bombers for states with a low budget. It could carry four .30 Mgs in the wings and one in the rear. Later models partially did not not mount them, but all could. First model with all metal, monocoque fuselage construction. Another innovation came in the form of integral fuel tanks, totaling 170 US gallons. Had still the original wing form of the NA-16. Later models changed that except the Peruan fighters. ⁽¹³²⁷⁾
NA-45	NA-16-1GV ⁽¹³²⁸⁾	Venezuela (FAV) ⁽¹³²⁸⁾	Pratt & Whitney R-1340 Wasp ⁽¹³²⁸⁾	3 ⁽¹³²⁸⁾	Possibly originally built to Brazilian contract ⁽¹³²⁸⁾

NA-50 Toritos	NA-50 / NA-16-5 ⁽¹³²⁸⁾	Peru (FAP) ⁽¹³²⁸⁾	Wright R-1820-G3 Cyclone ⁽¹³²⁸⁾ with 3 bladed constant speed prop⁽¹³²⁷⁾ rsp. R-1820-77 with 870 hp⁽¹³²⁹⁾	7 ⁽¹³²⁸⁾	Single seat fighter, NA-16-5⁽¹³²⁸⁾, based on NA-44. Still the original wing form of the NA-16, but shortened. Ordered by the Cuerpo Aeronáutico del Peru in August of 1938. Construction numbers 50-948 to 50-954. Very good around visibility because of sliding canopy of the O-47 observation plane. Armament two .30 Mg in the nose, provisions for 400lb bomb loads under the wings. The NA-50s were assigned to the 41st Flight of the 21st Fighter Squadron, based at Chiclayo, and serialed XXI-41-1 to XXI-41-7. With the 1941 war between Peru and Ecuado the NA-50 were in combat 'some minutes'. Two were lost, one by a kamikaze action, one by a bomb exploding while landing.⁽¹³²⁷⁾According to Dan Hagedorn: The CAP lost an NA-50 (XXI-41-2) on the 7th flown by Capt. Renán Elias Oliveira when, after a fighter-bomber sortie, he discovered that one of his bombs had hung up on one of the underwing racks. Flying out over the sea and endeavoring to dislodge it, he crashed into the sea during violent maneuvers. It is not clear if the bomb detonated, or if he lost control while trying to dislodge it. ⁽¹³³¹⁾. On July 23rd Tte. Jose Quinones in XXI-41-3 Pantera was part of an attack by 4 NA-50 on AA batteries. Being hit and without many options Quinones dived into the battery he believed to hit him.⁽¹³³¹⁾ Four of the Toritos survived the conflict and were transferred to the 21st Squadron, based at Las Palmas, where they served until their place was taken by P-36 Hawks in 1947. Transferred yet again, they became fighter trainers in the 4th Advanced Training Squadron of the 28th Training Squadron at the Air Academy. Wearing serials 28-4-10 to 28-4-13 and a familiar trainer scheme of blue and yellow, they survived in this role until 1950. Probably ended up in storage. In 1954 number 251 was rebuilt. In 1961 it was damaged in a demonstration flight. 1965 she was again repaired and put on a pedestal. ⁽¹³²⁷⁾ Slightly shorter wingspan than AT-6. 2 Mg in the cowling, 2 in the wing⁽¹³²⁹⁾ A drawing and a picture can be found in the Small Air Forces Observer 102⁽¹³³²⁾ and 59⁽¹³³³⁾.
NA-52	SNJ-1 ⁽¹³²⁸⁾	USN ⁽¹³²⁸⁾	Pratt & Whitney R-1340-6 Wasp (500 hp) ⁽¹³²⁸⁾	16 ⁽¹³²⁸⁾	Erste SNJ-1 (by Wikimedia, Author, Rights refer to here) Short metal fuselage, square rudder, late wings, fixed rear on canopy ⁽¹³²⁸⁾ as a combination of the Armys BC-1 improvements, Navy requirements and some NAA improvements.

The spec was called BC-2, then renamed to BC-1A. The Army re-evaluated the concept and re-designated it to Advanced Trainer, so the BC-1 became the AT-6 (in the model 59). ⁽¹³²⁹⁾
NA-56	NA-16-4 ⁽¹³²⁸⁾	China (ROCAF) ⁽¹³²⁸⁾	Pratt & Whitney R-1340 Wasp ⁽¹³²⁸⁾	50 ⁽¹³²⁸⁾	Similar to NA-55 (long metal fuselage, fixed gear and engine differences) ⁽¹³²⁸⁾

For France it was a BT-9B, called NA-57, and equipped with reverse throttles, a Wright R-975-E3 Whirlwind. 16 had not yet been delivered before the fall of France, they were transferred to Canada as Yale Mk.I. Such ex-French NA-57 as well as ex-French NA-64 were called Yale Mk.I!⁽¹³²⁹⁾
NA-58	BT-14/BT-14A (BT-9D) ⁽¹³²⁸⁾	USAAC ⁽¹³²⁸⁾	Pratt & Whitney R-985-25 Wasp Junior ⁽¹³²⁸⁾	251 ⁽¹³²⁸⁾	NA-58 BT-14 (by Wikimedia, Author, Rights refer to here) Similar to Harvard II except for fixed undercarriage and smaller engine. 27 re-engined with 400 hp (298 kW) Pratt & Whitney R-985-11 as BT-14A ⁽¹³²⁸⁾ One NA-23 was called BT-9D and equipped with 450 hp Pratt & Whitney R-985-25. It had a longer all metal fuselage, changed tail surfaces, larger cowling, exhaust stack behind the cowling on starboard, and a redesigned wing. The prototype then was renamed YBT-14 and the production batch BT-14. In 1941 27 BT-14 were modified to BT-14A with 400 hp Pratt & Whitney R-985-11A⁽¹³²⁹⁾
NA-59	AT-6-NA ⁽¹³²⁸⁾	USAAC ⁽¹³²⁸⁾	Pratt & Whitney R-1340-47 Wasp (600 hp) ⁽¹³²⁸⁾	94 ⁽¹³²⁸⁾	First examples converted from NA-55 while still on production line, some examples had small DF loop installed. ⁽¹³²⁸⁾ The Army re-evaluated the concept and re-designated it to Advanced Trainer, so the BC-1A Model 55 became the AT-6 (in the model 59). ⁽¹³²⁹⁾
NA-61	NA-16-1E/ Harvard I ⁽¹³²⁸⁾	Canada (RCAF) ⁽¹³²⁸⁾	Pratt & Whitney R-1340-S3H1 Wasp (600 hp) ⁽¹³²⁸⁾	30 ⁽¹³²⁸⁾	Later fitted with extended exhaust for cabin heater ⁽¹³²⁸⁾

Diverted with start of Pacific war to USAAF as P-64 ⁽¹³²⁸⁾ Different rudder than the NA-50, improved landing gear doors, two 20mm guns under the wing, two 8mm guns under the wing, two 8mm guns in the cowling. After revoking the delivery, they were transferred to California, stripped of their armament and taken over by USAAC as fighter trainers, designated P-64. They retained their Thai camouflage of Dark Brown/Darrk Green and Light Gray.⁽¹³²⁹⁾ For a photo of P-64, C/N 68-3062 and ex USAAF 41-19085, civil registration XB-KUU see https://www.facebook.com/LatamAviationHistory/photos/a.315950111857736.76425.315080478611366/606108656175212/?type=1

NA-71	NA-16-3 ⁽¹³²⁸⁾ rsp. NA-44⁽¹³²⁷⁾	Venezuela (FAV) ⁽¹³²⁸⁾	Pratt & Whitney R-1340-S3H1 Wasp (550 hp) ⁽¹³²⁸⁾ rsp. R-1340-7⁽¹³²⁷⁾	3 ⁽¹³²⁸⁾	Two nose guns and rear gun, no wing guns. ⁽¹³²⁸⁾The NA designation said it was based on NA-16-3, not NA-44 - and there is no evidence that it has been produced with armament. Anyhow it had been described as 'General Purpose Combat Aircraft' and 'Ground Cooperation Aircraft'. From photographical evidence the NA-71 belonged to the group of NA-44 successors. Construction numbers 71-3074/-3076 and became FAV 1, 2 and 3 in the Fuerza Aerea Venezolana. The final delivery took place in June or July, 1940, and the two survivors were taken out of service in 1943. According to information from the Fav-Club, it is possible that the aircraft were painted dark green during their short careers. ⁽¹³²⁷⁾
NA-72	NA-44 ⁽¹³²⁸⁾	Brazil (Army) ⁽¹³²⁸⁾	Pratt & Whitney R-1340-AN1/S1H1 Wasp (600 hp) ⁽¹³²⁸⁾	30 ⁽¹³²⁸⁾⁽¹³²⁷⁾⁽¹³²⁹⁾	Attack bomber, fitted with small DF loop under fuselage. ⁽¹³²⁸⁾ Starting on July 19th, 1940 the first batch of 20 NA-72 were delivered to Brazil with serials 72-3077 to 72-3096, followed by another 10 soon (72-4757 to 72-4766). The first batch had .30 machine guns, the second gad 7mm Colts. They had a pair of Venturis on the port side (what no other heavyweights had). The aircraft were ferried by Brazilian pilots beginning September 11th, 1940. They were simplly numbered 1 to 30. They arrived in groups from October till May. Number 12 (72-3088) was written off by an accident. Their duties were 3rd level pilot and gunnery training and coastal patrols. After the war thhe surviving 20 planes were redesignated AT-6 and given serials in the 1000s range. The last trainer was written off in 1958. The number 27 (72-4763) had been converted to an instructional airframe and was operated till December 20th, 1967. ⁽¹³²⁷⁾ NA-72 was the number for Brazil of the NA-44 export version⁽¹³²⁹⁾

Chile ordered 12 NA-44 in 1940, delivered February 1941. Source are different in the armament. Photos show just wing guns and outer wing bomb racks. The consstruction numbers were 74-4745 to 74-4756, serials 1 to 12. In March 1942 the number system was changed (when other AT-6 were under Lend & Lease), they became 201 to 212. Service was at the Flight Scool and at Air Group No 4. In 1943 aircraft 206, 207, 208 were transferred to Air Group 6. ⁽¹³²⁷⁾
