A small California-based aviation firm has announced that it recently completed engine and flight control testing on the ground on a stealthy unmanned aircraft known as the Fifth Generation Aerial Target, or 5GAT. The firm says that this design, which it originally developed as a stealth aerial target, could also serve in the "loyal wingman" role with manned combat jets and perform other operational missions.

Aviation Week was first to report that Sierra Technical Services had completed its first prototype 5GAT and had finished the various testing on Jan. 13, 2020. FlightGlobal subsequently published another report on these developments with additional detail about the unmanned aircraft's capabilities. The company says it hopes to fly the drone for the first time by the end of March of this year.
