WASHINGTON — The U.S. Army has chosen to move forward with the Iron Fist Lightactive protection system for its Bradley Fighting Vehicle, after evaluating the APS' ability to be installed on the vehicle.
The Army will now install the system onto a number of Bradley vehicles for a second phase of more extensive testing and evaluation, according to a release from the industry team providing the system.
That team, made up of General Dynamics Ordnance and Tactical Systems and Israeli companies IMI Systems and Elbit Systems, are working to integrate and test the system, designed to protect the Bradley from threats like anti-tank missiles, rocket propelled grenades and other weapons.
Iron Fist It uses a variety of sensors and countermeasures to stop those threats before they reach the vehicle. They include a electro-optical “soft kill” jammer and a physical “hard kill” interceptor to stop threats from getting closer to the vehicles.
“We are excited to move into Phase II and bring the vast capabilities of our Active Protection System to the Bradley Fighting Vehicle. We look forward to continuing to partner with the Army on advancing this important technology as well as enhancing integration capabilities across multiple Army platforms” Steve Elgin, vice president and general manager of armament and platform systems for GD-OTS, said in a statement.
While the release announcing the progress in testing did not say what the next phase would look like, it could mirror the same process the Army has used to qualify and evaluate Rafael's Trophy for the Abrams tank. More advanced tests will likely be against multiple types of threats in a simulated urban environment.
The decision can be seen as a vote of confidence in the system and could mean further fielding on a larger number of vehicles down the road.

DENVER, Oct. 3, 2018 /PRNewswire/ -- Today, at the International Astronautical Congress (IAC) in Bremen, Germany, Lockheed Martin (NYSE: LMT) experts revealed the company's crewed lunar lander concept and showed how the reusable lander aligns with NASA's lunar Gateway and future Mars missions. Concept video: https://vimeo.com/293133933 Lockheed Martin Crewed-Lunar-Lander The crewed lunar lander is a single stage, fully reusable system that incorporates flight-proven technologies and systems from NASA's Orion spacecraft. In its initial configuration, the lander would accommodate a crew of four and 2,000 lbs. of cargo payload on the surface for up to two weeks before returning to the Gateway without refueling on the surface. "NASA asked industry for innovative and new approaches to advance America's goal of returning humans to the Moon, and establishing a sustainable, enduring presence there," said Lisa Callahan, vice president and general manager of Commercial Civil Space at Lockheed Martin Space. "This is a concept that takes full advantage of both the Gateway and existing technologies to create a versatile, powerful lander that can be built quickly and affordably. This lander could be used to establish a surface base, deliver scientific or commercial cargo, and conduct extraordinary exploration of the Moon." The unique orbit of the lunar Gateway provides global lunar access for a lander. Having the ability to visit multiple sites with a reusable lander supports many international, commercial, and scientific communities, in addition to NASA's sustainable exploration of the Moon. After a surface mission, it would return to the Gateway, where it can be refueled, serviced, and then kept in orbit until the next surface sortie mission. "The Gateway is key to full, frequent and fast reusability of this lander," said Tim Cichan, space exploration architect at Lockheed Martin Space, who presented the lander concept at IAC. "Because this lander doesn't have to endure the punishment of re-entering Earth's atmosphere, it can be re-flown many times over without needing significant and costly refurbishment. That's a major advantage of the Gateway and of a modular, flexible, reusable approach to deep space exploration." The investments made in technology developed for Orion can be re-used to reduce the cost, complexity and development timeline. Some of the human-rated, flight-proven systems used in the design include avionics, life support, communications and navigation systems, and a light-weight version of its crew module pressure vessel. Reusable landers are enabled by the lunar Gateway and are important for sustainable exploration. Additionally, landed human lunar missions and a lunar orbiting outpost are valuable to prepare for sending humans to Mars. While the Moon doesn't have an atmosphere, there are still many lessons that apply to a future crewed Mars lander, such as: operations experience in a challenging and dynamic environment, operating and refueling out of orbit, long-duration cryogenic propulsion, and terminal descent navigation, guidance and control.
