| Designed by Donovan R Berlin to participate in a
USAAC fighter contest scheduled to take place on 27
May 1935, the Model 75 (the retroactive assignment of
Model numbers to earlier designs was attempted at
this time and the new fighter became the first design to
receive a Curtiss Model designation from the outset)
all-metal single-seat fighter was initiated in October
1934, flying on 15 May 1935. Featuring a monocoque
fuselage and a multi-spar wing, the Model 75 was
powered by a 900hp Wright XR-1670-514-cylinder tworow
radial. Proposed aimament comprised one 12.7mm and one 7.62mm machine gun. The
unsatisfactory behaviour of the Wright engine resulted
in its replacement by a 700hp Pratt & Whitney R-1535 Twin Wasp Junior. This, too, proved troublesome and
was succeeded by a 950hp Wright XR-1820-39 (G5)
Cyclone nine-cylinder radial with which the prototype
became the Model 75B. During USAAC trials, the Model
75B took second place to the Seversky SEV-1XP, which
was to enter production as the P-35.

BHH, 27.12.2021 19:14 Outwardly seems quite similar to the Northrop N3A /Vought V-141 /V-143 family. reply | Klaatu83, e-mail, 11.10.2011 03:18 "Hawk-75" was the company company name for the fighter that the Army Air Corps referred to as the "P-36". There were many different versions of the "Hawk-75" sold for export. The RAF called their version of this fighter the "Mohawk". Aircraft "X17Y, pictured above, was actually the first prototype, shown in original version (top), and later, (below), fitted with a different engine and a scalloped indentation behind the cockpit to improve rear visibility. reply |
