The single-bay biplane with equal-span wings, the Curtiss water-cooled inline engine with a neat spinner, N-type interplane struts, and the two-cockpit arrangement with a rear observer's Scarff ring are characteristic.

History

The O-1 Falcon entered USAAC service in 1925 and was progressively developed through the O-1B to O-1G, with the O-1E being a mid-series variant. The Curtiss D-12 engine gave it excellent performance for its era. Falcons served on the US-Mexican border and in various overseas territories during the late 1920s.

Variants

The O-1 series ran from A through G; the E variant used the Curtiss V-1150 engine; related export versions were designated Hawk and served with several Latin American air forces.

Where you'll see it

O-1 Falcons served with USAAC observation squadrons throughout the continental United States and in the Panama Canal Zone and Philippine Islands, remaining in service until replaced by monoplane types in the mid-1930s.
