Piasecki PV-14 / XHJP-1

After the first lying banana, Piasecki immediately set to work on a specification, issued by the US Navy Bureau of Aeronautics in 1945, for a shipboard helicopter to be used on aircraft carriers and larger vessels for SAR, liaison, replenishment and plane guard duties. The result was the PV-14 (designated XHJP-1 by the US Navy). Though only two prototypes were built, it spawned the PV-18 / HUP / H-25 series of heicopters.
