History

The P-1 evolved from the successful R-6 racing aircraft and entered service as the Army's standard fighter. Its Curtiss D-12 engine gave it a long, sleek nose profile that became characteristic of Curtiss fighters of the era. The Hawk family was developed through numerous variants and export versions, directly evolving toward the P-6 Hawk and later the P-36 and P-40 monoplanes.

Variants

Variants included the P-1A through P-1C with progressive improvements; the export Hawk I was a related type; the O-1 Falcon was a two-seat observation derivative of the same basic design.

Where you'll see it

Served US Army Air Corps pursuit squadrons from 1925 to the early 1930s, gradually replaced by improved biplane and monoplane fighters.
