The Air Force Research Laboratory has awarded a contract for Mjolnir, a next-generation counter electronics weapon system, to defend against adversarial drone activity, to Leidos Inc.

Building upon the success of the Tactical High-Power Operational Responder (THOR) technology demonstrator, Leidos will build an advanced high power microwave (HPM) weapon system to bring the newest technology to bear against the growing threat from unmanned aircraft.

"The new prototype will be called Mjolnir, the mythical Norse God Thor's mighty hammer," said Adrian Lucero, THOR program manager at AFRL's Directed Energy Directorate at Kirtland AFB, New Mexico. "Because THOR was so successful, we wanted to keep the new system's name in the family."

The AFRL team, working from Kirtland Air Force Base, are experts in High Power Electromagnetics technology. The THOR demonstrator used bursts of intense radio waves to disable small unmanned aircraft systems (sUAS) instantly.

"The lessons learned from our successful overseas operational testing, now define the new requirements for the Mjolnir program, and will be the baseline configuration for future systems to be deployed around the world," Lucero said.

The $26 million Mjolnir prototype, will use the same technology as THOR, but will add important advances in capability, reliability, and manufacturing readiness.

"We are transitioning AFRL technology to our industry partner Leidos, who has the knowledge and capability to build multiple systems in the future," said Lucero. "Mjolnir will focus on creating a detailed blueprint for all future cUAS HPM systems with enhanced range and technology for detecting and tracking UASs. This will ensure the U.S maintains our electromagnetic spectrum superiority."

AFRL is working closely with cross-service partners to field these systems for base defense.

"As the danger from drone swarms evolves, all services are working closely to ensure emerging technologies like Mjolnir, will be ready to support the needs of warfighters already engaged against these threats. The program will begin this spring with a delivery of the prototype weapon in 2023," said 1st Lt. Tylar Hanson THOR deputy program manager.

European nations sign 7-bn-euro drone contract
Paris (AFP) Feb 24, 2022
Germany, France, Italy and Spain signed Thursday a 7.1-billion-euro contract to build and operate a fleet of surveillance drones, said Airbus, leader of the consortium of defence firms tapped for the project. Baptised Eurodrone, the twin-motor aircraft with a 30-metre wingspan similar to some commercial planes, will be able to carry out intelligence-gathering, surveillance as well as combat operations. The remotely-piloted 10-tonne drone, to be built by a consortium lead by Airbus, will be capab ... read more
