The P-V Engineering Forum PV-2, or Piasecki PV-2, was the brain child of Frank Piasecki. The PV-2 is best know for being the second successful helicopter flown in the United States. The PV-2 first flew on April 11, 1943.

The PV-2 is now on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center
