The P-1A's defining feature is its long, narrow-fronted water-cooled V-12 giving the nose a pointed, almost Art Deco look compared to the blunt radial-engined biplanes of its time. The lower wing is shorter in span than the upper, and external frontal radiators are visible beneath the nose.

History

The P-1A entered service in 1925 as a refined version of the earlier XPW-8B, powered by a Curtiss V-1150 (D-12) liquid-cooled engine. Its clean lines and high performance for the era made it a favourite for air-race appearances and public demonstrations. Curtiss produced 25 P-1As before moving to subsequent Hawk variants.

Variants

The Hawk biplane family extended from the P-1 through P-1F, with parallel export variants sold as Hawk I and Hawk II. The P-1A differed from the P-1 primarily in using Curtiss-Reed metal propellers and minor equipment changes.

Where you'll see it

The US Army Air Corps flew the P-1A with the 1st and 27th Pursuit Squadrons, with examples also exported to Bolivia and other South American air arms.
