The AD-150 was a proposed unmanned vertical lift aircraft for the United States Marine Corps designed by American Dynamics Flight Systems. The company conducted wind tunnel and iron-bird rig testing with the intention for the AD-150 to support the US Marine Corps Group 4 expeditionary UAS requirement, formerly referred to as the Vertical Unmanned Air System, or VUAS.
The twin-ducted fan aircraft would have achieved speeds of 300 knots and was envisioned to serve as a reconnaissance asset to be used in conjunction with the MV-22. The AD-150 could also be flown as a medical evacuation aircraft for a single Marine.
