Curtiss P-1 Hawk

The first airframe to gain the then new U.S. Army "Pursuit" designation was the Curtiss Model 34A/O Hawk. The U.S. Army took delivery of 81 planes from 1925 to 1929.

The P-1 Hawk burns 16.2 gallons of aviation fuel per hour at routine usage. A full load of fuel and ammo costs $32.

Design Notes:

Historical wing area was 252 sf. The weight, cost and HPs of the chassis were doubled to increase design weight; Lwt still needed to be increased 10% to the historical. The fuel capacity and MG load outs are a guess. Design payload was 640 lbs; the historical value has been substituted. Design aSpeed was 177 mph. Performance calculations were based on historical values for wing area and loaded weight. The Body MGs are synchronized, lowering RoF by 10% (see p. W:MP8).



The P-1A was the initial design model. It lacked wheel brakes and other equipment changes that were added to the -C. 25 built.

The P-1B was fitted different powerplant built by Curtiss, but was otherwise identical to the -A. 23 built.

The P-2 was actually 5 P-1s with 373-kW turbo-supercharged engines.

The P-3 was a single experimental P-1 with a 306-kW radial engine.

The P-5 Superhawk was a turbocharged version of the P-1, intended for higher altitude flying. It featured a cockpit heater and enlarged propeller. Five planes were built. The Superhawk was in service from 1928 to 1932.
