The Army issued a specification for a new engine, known as the R-1454, on 15 Aug 1923.

The first engine was delivered in Sept 1924 and it gave up to 405hp @ 1650rpm. A modified cylinder developed by Heron (Type M) was fitted to the engine, and the Army instructed Curtiss to proceed with the other engines called for under the contract in Feb 1926.
