The PV-2 was the first successful design by PV-Forum, the engineering consulting company formed by Frank Piasecki and Harold Venzie (hence 'PV') after the former left the Platt-LePage Aircraft Company. The aircraft first flew on April 11, 1943. It was the second helicopter designed by an American to successfully fly. The success of the aircraft acted as a 'springboard' for further government contracts to be awarded to the company from the U.S. Navy which would lead to the formation of the Piasecki Aircraft Corporation.
