Long Endurance Drones Made in the USA

The Greased Lightning UAS is under development and is not yet available.

The Greased Lightning Paradigm Shift

Greased Lightning is a true no compromise solution to the long endurance VTOL paradox, with the aerodynamic efficiency of a conventional fixed wing with full VTOL capability.

  • Eliminates the requirement for additional ground support equipment like launch catapults and landing catch mechanisms

  • Propellers designed for a relatively low tip speed resulting in a marked reduction in noise

  • Endurance of 24 hours in the forward flight mode

Superior Mission Performance!

Greased Lightning Transition

The wings and horizontal stabilizer rotate with fixed motor pods to facilitate vertical flight.

Developed by NASA and now being commercialized by Advanced Aircraft Company!
