Soon after receiving an order from the USAAC for an
evaluation quantity of its Model 75 fighter, Curtiss
began to consider the export potential of the basic design as a successor to the Hawk III biplane. A simplified
version with a fixed cantilever undercarriage was
evolved for which the export appellation "Hawk" was
retained and to which the model number "75" was
appended. Two demonstration examples of the Hawk
75 were built in parallel with the three Y1P-36s ordered
by the USAAC, these being powered by the 875hp
Wright Cyclone GR-1820-G3 Cyclone nine-cylinder radial. One mounted an armament of one 12.7mm and one 7.62mm gun in the nose, and the
other having this armament supplemented with a pair
of wing-mounted 7.62mm weapons. The two
demonstration aircraft were assigned the designation
Hawk 75-H (Curtiss having adopted the practice of allocating
suffix letters to each version of the basic design,
the Y1P-36, for example, being the 75-E, the XP-37
being the 75-1, etc), the two-gun example being lost and
the four-gun aircraft being sold to China. The latter
country was the first quantity purchaser of the fixed undercarriage
Hawk 75, a total of 30 being delivered
under the designation Hawk 75-M between May and
August 1938. A further 82 were to have been assembled
by CAMCO (Central Aircraft Manufacturing Company)
at Loi-wing, but these were cancelled in favour of
assembly of the more advanced Hawk 75A-5. The delivery
followed from November 1938 of 29 aircraft to
Argentina under the designation Hawk 75-0, these
having an armament of four 7.62mm guns, and a
further 20 examples were licence-built by the FMA. Delivered
simultaneously to Thailand were 12 Hawk
75-Ns, these having two fuselage-mounted 7.62mm
guns and two underwing 23mm Madsen cannon. The
characteristics of all versions of the fixed-undercarriage
Hawk 75 were essentially similar.

Brad is correct. The only one is in Bangkok, where I live most of the time. I have current photos of it if there is a way to post them here. Please advise via my email as I would be happy to post them. I also have photos of the only Hawk III, also in Bangkok. Both are in what appears to be original condition. While they are now inside, both were outside for years and have expected wear for the tropical heat and humidity including some corrosion. Both also have documented combat history.

Can anyone tell me what P-36 was used by the 21st pursuit squadron in the battle for Bataan.
"Hawk 75" was the manufacturers's designation for the fighter which the Army Air Corps called the P-36. That designation also included all the export versions, not just the fixed landing gear version (of which few were actually built.) The term Hawk 75 included those built under the largest export order, which was for the French Air Force. After the Fall of France many of the undelivered French Hawk 75s ended up in the RAF, under the British designation, "Mohawk".

The only fixed gear Hawk 75 known to exist is the Hawk 75N in the Royal Thai Air Force Museum in Bangkok. It is in excellent condition considering it's age.
There was never a fixed gear P-36. That is the US Army designation. The Hawk 75 is the factory designation used mainly for export.
There is a retractable gear Hawk 75A flying in Europe.

Wright Aero. had a Hawk 75 and used it for product improvement testing including flame supression.

I had no idea that a fixed gear P-36 existed until I saw a photo of one in Chinee service with a caption stating that Chenault flew it and scored some victories against the Japanese.
I have always admired the P-36 and wish I could have flown it.
Do you have any comments about this aircraft ?
