Hermeus names Zach Shore CEO; founder Piplica becomes chairman

Hypersonic aircraft developer Hermeus appointed Zach Shore as chief executive officer effective June 1, with founding CEO AJ Piplica transitioning to executive chairman. The leadership change comes as Hermeus advances its uncrewed Quarterhorse Mk 2.1 - billed as the world's first privately developed unmanned supersonic jet, which has flown to Mach 1.21 - and develops the larger Darkhorse, for which it has accepted its first Pratt & Whitney F100 engine to integrate into its Chimera II turbine-based combined cycle propulsion system. The company has won a $159 million Defense Department contract exploring military applications of its high-speed technology.
