One of the Pentagon's most secretive groups of experts has revealed renderings of its latest military plane meant for unique, critical special operations missions.
The new plane, dubbed the X-76, is part of a joint effort with the US Special Operations Command and the plane's manufacturer, Bell Textron.
The X-76 designation marks the 250th anniversary of the United States.
The Defense Advanced Research Projects Agency (DARPA), the Pentagon's advanced research arm, announced the next-generation high-speed, runway-independent aircraft on Monday.
'Eliminating one of the battlefield's most difficult choices - between the high speed of an aircraft that needs a runway and the go-anywhere flexibility of a slower helicopter - is the goal of DARPA's Speed and Runway Independent Technologies (SPRINT) Program,' DARPA wrote in its press release.
The agency released two renderings of the next-generation plane showing both an unmanned and manned version.
The X-76 blends plane and helicopter features by utilizing both vertical takeoff and landing (VTOL) systems with high-speed jet capabilities, aiming to eliminate the military's dependency on runways.
It also appears to have a wide-body frame, indicating that it may be able to transport vehicles in addition to troops.
If the X-76 can carry both troops and vehicles, it could transform how US forces deploy heavy assets, including artillery and tanks, into areas with no landing strips.
'The SPRINT program is a joint effort between DARPA and U.S. Special Operations Command to advance technologies that could break the long-standing military trade-off between the high speed of fixed-wing aircraft and the agile, runway-independent operations of vertical takeoff and landing platforms,' the release said.
'The design, construction, and flight testing of the X-76 will drive innovative, runway-independent, vertical-lift capability with jet-like cruise performance and inform future needs.'
The primary goal of the program is to create a combat aircraft capable of cruising at speeds above 460 miles per hour, that can hover in 'austere environments' and can operate from 'unprepared surfaces.'
'For too long, the runway has been both an enabler and a tether, granting speed but creating a critical vulnerability,' said Commander Ian Higgins, DARPA's SPRINT program manager.
'With SPRINT, we're not just building an X-plane; we're building options. We're working to deliver the option of surprise, the option of rapid reinforcement, and the option of life-saving speed, anywhere on the globe, without needing any runway.'
The X-76 is expected to begin flight testing in 2028.
It is the latest aircraft announced in the Pentagon's X-series, or experimental, aircraft.
The Pentagon is also developing the X-47 next-generation fighter and the X-65, an experimental aircraft built without the moving flaps and rudders found on conventional planes.
The X-65, after delays, is now expected to begin test flights in 2027.
The next-generation fighter, the X-47, has already undergone hundreds of hours of test flights, according to DARPA.
