The Wright R-2600 Cyclone was basically a war-time engine, with over
50,000 examples, at approx 1,700 hp, built in the Cincinnati plant
alone, followed by the BB-series at 1,900 in 1944. Production of all
2600s stopped at VJ-day. Wright had already developed the R-3350
Duplex Cyclone or Cyclone 18, back in 1936, and that became Wright's
postwar engine.

Pratt & Whitney dropped its R-2180 Twin-Hornet, 1,400 hp on test in
1935, as soon as Wright started testing its R-2600, and enlarged its
own R-2600 into the R-2800 Double Wasp; production of the latter
continued post-war.
