Advanced Aircraft Company (AAC) is a developer and manufacturer of hybrid fuel-electric unmanned aircraft systems for defense applications. Utilizing multirotor configurations with fuel-electric propulsion and aerodynamic airframes, the systems are designed for long-endurance flights with the capability to carry multiple simultaneous sensor payloads. Designed for ISO AS9100 production standards, the systems employ line replaceable components, ensuring rapid servicing in the field with minimum downtime. Open modular architecture allows for mission-specific reconfiguration while a continuous development program lengthens aircraft service life and increases their capabilities as new technologies are integrated over time. AAC systems are highly portable and can be launched in minutes without the need for support infrastructure. All AAC aircraft are NDAA Sec. 848 compliant and built in the USA with qualified traceable parts. AAC is a veteran-owned and operated company founded in 2017 with headquarters in Hampton, Virginia. AAC's first product is the HAMR (Hybrid Advanced Multi-Rotor) UAS, a long endurance multi-rotor utilizing hybrid electric propulsion and patent pending aerodynamic design features. The HAMR can fly for over 2 hours with a 4 pound payload. AAC's future product is the Greased Lightning UAS. AAC has licensed production rights from NASA for the GL-10 technology and will improve on the NASA technology in numerous ways. It is projected that AAC's upgraded Greased Lightning will fly for 19 hours with a 5 pound payload. This unique aircraft can takeoff and land without any launch and recovery equipment.
