[1] The company's origins dated back to 1936 with the formation of the P-V Engineering Forum in 1940 and it was renamed the Piasecki Helicopter Corporation in 1946.

[4] Piasecki developed and flight-tested the X-49 experimental compound helicopter, with its first flight in 2007, later completing all Phase 1 requirements.

Piasecki bid on the Future Vertical Lift program,[5] but was not chosen when that project moved into its Joint Multi-Role Technology Demonstrator (JMR-TD) phase in 2013.

M4 was designed to accommodate cargo, patients, troops or a combination of any of these with its rapidly reconfigurable interior.

[8] Piasecki is working for the PA-890, an electric powered helicopter with targets for lower operating cost, reduced noise, and zero direct emissions.
