The R-2600 series engine was introduced in 1939, initially rated at 1,500 hp. With improvements, it later reached a rating of 1,800 hp. In military use, it was used on Army Air Forces A-20s and B-25s as well as some Navy torpedo and patrol bombers. It also gained fame powering the well-known Boeing Model 314 Clipper, which offered transoceanic passenger service beginning in 1939. After the end of World War II, the R-2600 was superseded by larger radial engines.
