Electric aircraft developer Beta Technologies is expanding the scope of its work with advanced propulsion systems through a partnership with General Dynamics Applied Physical Sciences to support new undersea vehicles. The companies announced their partnership on September 26, saying that Beta will manufacture hardware for the major U.S. defense group, as well as provide engineering services.

The project will build on the electromechanical engineering work Beta has conducted for its Alia aircraft, including the Alia 250 eVTOL model and the CX300 conventional takeoff and landing version. The partners have not specified what types of undersea vehicles they are addressing or the missions these might undertake.
