Piasecki was given a US Army contract to create a compound helicopter using the AH-1W SuperCobra and incorporating their VTDP technology as well as lifting wings.

The Speed Cobra, or simply Piasecki Cobra, was what they came up with.

The SpeedCobra was never built, however a second contract with the US Navy in 2003 resulted in the successful construction of the X-49 Speedhawk in 2007.

This is essentially a continuation of my first post on this subreddit.

My next post will be a continuation of this one involving another awesome attack helicopter. 😉

Spoiler alert, >!just kidding!<.
