  Pentagon terminates program for redesigned kill vehicle, preps for new competition

  By: Jen Judson UPDATE: This story has been updated to include a statement from Raytheon. WASHINGTON — The Pentagon has moved from taking a “strategic pause” on the Redesigned Kill Vehicle program to outright killing it. The Department of Defense decided to terminate the current Boeing contract to develop the RKV — effective Aug. 22 — “due to technical design problems,” according to an Aug. 21 statement by the department. Raytheon is the actual developer of the RKV and serves as a sub-contractor to Boeing. The RKV would have replaced the current Exoatmospheric Kill Vehicle (EKV) on the Ground-Based Interceptor, which makes up the Ground-based Midcourse Defense (GMD) system designed to protect the homeland from ballistic missile threats. It would have also been fielded on all future ground-based interceptors — a total of 64 ultimately. The EKV is designed to destroy targets in high-speed collisions after separating from the booster rocket. The EKV required technical changes in the past several years due to issues in tests. The Missile Defense Agency decided to initiate a program to redesign the kill vehicle. In the meantime, MDA has had several successful tests of the GMD system with the EKV following engineering changes. Now that the RKV is dead in the water, the Pentagon plans to move forward with a new, next-generation interceptor competition, the statement said. According to a defense official, no more ground-based interceptors will be built, and all future interceptors that are fielded as part of the GMD system will be the new interceptors. “Ending the program was the responsible thing to do,” Mike Griffin, undersecretary of defense for research and engineering, said in the statement. “Development programs sometimes encounter problems. After exercising due diligence, we decided the path we're going down wouldn't be fruitful, so we're not going down that path anymore. This decision supports our efforts to gain full value from every future taxpayer dollar spent on defense.” With the blessing of the undersecretary of defense, Griffin made the decision on Aug. 14 to terminate the program, one week after he told reporters at the Space and Missile Defense Symposium in Huntsville, Alabama, to expect a decision on the way forward for RKV soon. MDA and Boeing in December 2018 deferred a critical design review of the RKV “due to the failure of certain critical components to meet technical requirements as specified in the development contract,” the statement noted. After MDA assessed the issues, it issued a stop work order on the contract in May to analyze alternative options. “The department ultimately determined the technical design problems were so significant as to be either insurmountable or cost-prohibitive to correct,” the statement said. The DoD plans to take data garnered from research and testing of the RKV prior to its cancellation to inform the next-generation interceptor program, “which will include a new kill vehicle,” according to the statement. “The U.S. Missile Defense Agency is updating its requirements in the face of an increasingly complex threat environment," Raytheon said in a statement. The company “supports their decision to cease work on the Redesigned Kill Vehicle (RKV) and initiate a competition for the next-generation interceptor to meet these advanced threats. Raytheon will continue to develop and offer a wide range of advanced missile defense technologies available to protect the United States now and in the future.” There are 44 ground-based interceptorss in place at Fort Greely, Alaska, and Vandenberg Air Force Base, California, with plans to add 22 additional missile silos at Fort Greely to support 20 more ground-based interceptors. The defense official said the Pentagon is still working through the details of a new, next-generation interceptor competition, including when it will be initiated and the pace at which the technology will be developed and fielded. https://www.defensenews.com/pentagon/2019/08/21/dod-tanks-redesigned-kill-vehicle-program-for-homeland-defense-interceptor/

  Northrop Grumman to Develop Advanced Air-to-Air Missile Engagement Concept

  Posted on February 11, 2021 by Seapower Staff REDONDO BEACH, Calif. — Northrop Grumman Corp. has been awarded a contract by the U.S. Defense Advanced Research Project Agency (DARPA) Tactical Technology Office to develop an advanced technology weapon concept designed to significantly increase engagement range and weapon effectiveness of U.S. forces against adversary air threats, the company said in a Feb. 10 release. “Our collaboration with DARPA is the critical first step in the development of innovative operational concepts and solutions that will enhance our warfighter's combat capability against a rapidly growing threat,” said Jaime Engdahl, program director, kinetic weapons and emerging capabilities, Northrop Grumman. “The LongShot program enables us to combine our digital engineering skillset with our extensive knowledge in advanced technology weapons, autonomous systems and strike platforms to increase weapon range and effectiveness.” Spurred by rapid technological advancements and an ever more dangerous and disruptive battlefield, DARPA's LongShot program will explore new lethal engagement concepts by leveraging multi-modal propulsion, weapon systems that can be operationally deployed from existing fighters or bombers. DARPA's advanced aerospace systems activities are focused on utilizing high pay-off opportunities to provide revolutionary new system capabilities, as opposed to incremental or evolutionary advancements, in order to achieve undeterrable air presence at dramatically reduced costs. The LongShot program enables Northrop Grumman to combine its expertise in weapon system design, survivability, autonomy, advanced mission systems and rapid prototyping to deliver advanced solutions that help to maintain a competitive military advantage in highly contested environments. https://seapowermagazine.org/northrop-grumman-to-develop-advanced-air-to-air-missile-engagement-concept/
