The Curtiss A-12 Shrike was the United States Army Air Corps' second monoplane ground-attack aircraft, and its main attack aircraft through most of the 1930s. It was based on the A-8, but had a radial engine instead of the A-8's inline, water-cooled engine, as well as other changes.

Design and developmentEdit

The Model 60 was developed from advancements of the A-8 and the experimental YA-10. However, it became obsolete after a short use period, mainly because of fast-improving aviation technology, as well as the USAAC's desire for multi-engined attack aircraft.[2]

The most obvious difference between the A-12 and the A-8 is the air-cooled, radial engine in the A-12, which replaced the A-8's inline, water-cooled engine. This was a response to the USAAC's move toward a preference for radial engines, especially in attack aircraft. The rationale behind this preference is that the radial engine has a lower profile, making it less vulnerable to ground fire, and a simpler cooling mechanism, which is also less prone to groundfire, as well as overall maintenance problems.[2]

These aircraft retained the open cockpit introduced in the A-8 production batch, and carried the same weapons load. In an attempt to improve pilot/observer co-operation the rear cockpit was moved forward sufficiently for its glazed covering to form a continuation of the fuselage decking behind the pilot's cockpit.[3]

Nine USAAF A-12s were still in service at Hickam Field on 7 December 1941, but they saw no combat.[4]

Operational historyEdit

A-12s served with the 3rd Attack Group plus the 8th and 18th Pursuit Groups. Surviving Shrikes were grounded just after Pearl Harbor was bombed in December 1941.[5]

  • Chinese Nationalist Air Force received 20 A-12 Shrikes in 1936, arming the 27th and the 28th Squadron of the 9th Group. When full-scale war broke out between Japan and China, they were used. The initial success including the downing of four Japanese Aichi D1A1 carrier-based dive bombers on 15 August 1937. However, after deploying in ground support missions in Shanxi, most did not survive and the extremely few left were reassigned to training duties.[2]
