Kratos Defense & Security Solutions demonstrated a trolley-based launch system for the XQ-58A Valkyrie unmanned aerial system recently.

A Kratos Trolley Launch System (KTLS)-assisted XQ-58A can take off from runways or traditional roads without reducing its payload or the fuel required for conventional retractable launching gear.

Moreover, it does not impact the system’s overall cost.

“As we watch peer adversaries in both their preparations and active conflicts, and at the same time see the DoD budget impacts in our own nation, we have challenged ourselves at Kratos to solve today’s defense challenges with solutions that are realizable, near term achievable, and affordable,” Kratos Unmanned Systems Division President Steve Fendley said.

A KTLS-launched drone generates take-off thrust solely from its jet engine, unlike with a Rocket Assist Take Off (RATO) system or other acceleration producing mechanisms.

The trolley system detaches itself from the aircraft during takeoff, leaving the XQ-58 to land through a parachute recovery system after a sortie.

Inflatable bags help cushion the landing.

“For KTLS takeoff, which is fully autonomous, the aircraft engine throttles up just like a conventional jet takeoff, and the combined system, Valkyrie and KTLS, accelerates down the runway,” Kratos explained. 

“Ultimately, at lift-off speed, the aircraft flies up and away from the KTLS which then deploys drogue chutes and brakes to a stop on the runway while the aircraft proceeds to its flight mission.”

The KTLS is the second of three Valkyrie launch methods after the RATO, which allows the aircraft to take off without runways, from unprepared locations. 

The third method has not yet been disclosed.

The XQ-58 has been in development since 2019 with the intended primary task of flying alongside a manned aircraft.

It can carry a range of weapons in its internal bay and under its wings and can be configured for various tasks, including electronic warfare and communication relays.

The XQ-58 has a maximum launch weight of 6,000 pounds (2,721 kilogram), a maximum altitude of 45,000 feet (13,716 meters), and a range of up to 3,000 miles (4,828 kilometers).
