WASHINGTON — The U.S. Army is recycling demilitarized rocket motors and repurposing the materials to make test missiles and it's saving the service money, according to Thomas Webber, director of the Army's Space and Missile Defense Command Technical Center.
These test missiles are called “zombies” and save the Army from having to destroy old boosters, giving them a new life, Webber said during the Defense News Space and Missile Defense Symposium Debrief event Aug. 5.
The effort started several years ago when the Army's Program Executive Office for Missiles and Space and the Patriot air and missile defense lower-tier product office began running out of targets for tests and spending “a lot” of money to buy more targets, Webber said.
The tech center proposed a “significantly cheaper” solution of using recycled motors reaching the end of operational life that would be appropriate for both developmental and operational missile tests, which are accurately representative of ballistic missile threats, he said.
Following a demonstration at the end of 2016, the zombies have taken off.
“We've been very successful,” Webber said. Since then, the program has expanded, providing targets not only for Patriot testing, but also the Missile Defense Agency and foreign military sales test events.
The Army has built seven targets to date. There are three variants: Pathfinder Zombie; the Black Dagger Zombie that adds an additional booster — the Terrier MK70 — for longer ranges; and Sabre, a shorter-range version.
A zombie was the target used in a recent critical test showing the Patriot system could be interoperable with the Army's Terminal High Altitude Area Defense system, Webber said.
Another target was successfully deployed in a June 25 test at White Sands Missile Range, New Mexico, for a foreign military sales customer.
The targets will be used in some of the upcoming tests that will help officials make decisions on the Lower-Tier Air-Defense Sensor, the future radar for the Army's Integrated Air-and-Missile Defense System to replace Patriot, Webber noted.
Specifically, a Black Dagger will be used during the IAMD Battle Command System limited-user test coming up next month.
“It has been a tremendous boon for us to be able to provide a more affordable, effective target,” Webber said.
He added that the Army is saving roughly 50 percent of what it would cost to replace targets simply by buying more. “We can turn these around pretty quickly and support those operational test events,” he said.
And it has provided “the capability needed to be able to make sure that we're validating and testing those operational weapon systems with regular and recurring test events,” Webber said.

by Sandra Erwin Airbus is ramping up satellite production in Florida and hopes to attract Pentagon buyers. WASHINGTON — The first project of the newly created Space Development Agency will be to design a large constellation of commercially produced satellites in low Earth orbit to serve as a communications layer and take over military space missions ranging from missile tracking to navigation. Airbus is preparing to start cranking out 32 satellites every three weeks for the broadband venture OneWeb. It built an assembly line on Florida's Space Coast to manufacture up to 648 satellites for OneWeb but also hopes to ramp production to fill orders for the Defense Department, intelligence community and other U.S. government buyers, Nicolas Chamussy, the outgoing head of Airbus Space Systems told SpaceNews on Monday at the Satellite 2019 conference. The company received a $2.9 million contract last fall from the Defense Advanced Research Projects Agency to produce satellite buses for DARPA's Blackjack program, an experiment intended to show the military utility of LEO constellations and mesh networks. DARPA will marry up commercial satellite buses with military sensors and payloads. Former DARPA official Fred Kennedy conceived the Blackjack project and is now head of the Space Development Agency. He said the SDA will tap into the commercial industry's mass satellite production capabilities in order to build a military constellation in LEO. Airbus' main satellite manufacturing plant is in Toulouse, France. It now has U.S.-based design teams staffed with U.S. citizens as well as the Florida production facility, Chamussy said. “It's an opportunity for the U.S. government” to take advantage of these capabilities, he said. The U.S. plant only builds commercial satellites but it could be expanded to produce classified spacecraft, he said. The contract with DARPA has been valuable to Airbus to learn about U.S. defense programs and as a stepping stone to possibly other projects, Chamussy said. “With DARPA, we are learning how to work together, we are trying to understand if our platform is a valuable asset for the U.S. government.” The company is focused now on making satellites and installing OneWeb payloads, but “we can install whatever you want,” he said. For the military, the same satellites could carry positioning, navigation and timing (PNT), electronic warfare, Earth observation or weather payloads. “This is the beauty of have a design team and dedicated facility in U.S.,” said Chamussy. Airbus is hoping to be chosen as the satellite supplier to Canadian satellite operator Telesat, which also received a DARPA Blackjack contract to study the use of commercial buses in LEO-based military systems. Airbus is competing against a Maxar Technologies-Thales Alenia Space team for a contract worth an estimated $3 billion to build Telesat's megaconstellation. Chamussy told reporters at a news conference on Monday that the company expects to submit a proposal in the coming months. “We are still waiting for the request for proposals,” he said. Chamussy insisted that the Telesat concept is very different than OneWeb because the Canadian operator is asking for a full “end to end” system that includes not just the satellites but also ground systems and managed services. Airbus announced last month that Chamussy will be stepping down as executive vice president of Airbus Space Systems under Airbus Defence and Space. He will be replaced by Airbus Defence and Space executive Jean-Marc Nasr. Chamussy declined to comment on whether he will stay at Airbus or in what capacity. https://spacenews.com/airbus-eyes-opportunities-in-future-u-s-military-leo-constellations/

By: David B. Larter NATIONAL HARBOR, Md. — The U.S. Navy is considering a significant change to its new stealth destroyers, one driven by the change of mission announced in last year's budget documents, the head of the program said May 7 at the Sea-Air-Space conference. The service has been struggling to find a use for the ship's advanced gun system — the largest of its type fielded by the service since World War II — and now is considering stripping them off the platform entirely, said Capt. Kevin Smith, the DDG-1000 program manager at Program Executive Officer Ships. The Navy sidelined the guns after the service truncated the buy to just three ships, and after the ammunition, called the Long-Range Land-Attack Projectile, ballooned in price to more than $800,000 per round. "The guns are in layup,” Smith said. “We're waiting for that bullet to come around that will give us the most range possible. But given that that is offensive surface strike, we're going to look at other capabilities potentially that we could use in that volume.” The ships shifted missions from land attack to ship-hunting and -killing last year. The Navy is integrating the SM-6 missile, which has a surface-attack mode, and are integrating the maritime strike Tomahawk to fill out the new capabilities. In April testimony, the Navy's top requirements officer, Vice Adm. William Merz, told Congress that the slow development of the Advanced Gun System was holding back the Zumwalt. “Even at the high cost, we still weren't really getting what we had asked for,” he said. “So what we've elected to do is to separate the gun effort from the ship effort because we really got to the point where now we're holding up the ship.” The Navy has touted the ship's excess space, weight, power and cooling as advantages the service would want throughout the ship's life. Everything from directed energy and electromagnetic rail guns to electronic warfare equipment has been floated as add-ons to the Zumwalt-class destroyers. The Navy got in its present pickle with the 155mm/.62-caliber gun with automated magazine and handling system because the service cut the buy from 28 ships, to seven, and finally to three. The AGS was developed specifically for the Zumwalt class, as was the LRLAP round it was intended to shoot. There was no backup plan, so when the buy went from 28 to three, the costs remained static, driving the price of the rounds through the roof. The program itself is coming along, said Smith. The Zumwalt is going through trials as its combat system installation wraps up; the Michael Monsoor is heading into the yards for its combat system installation; and the Lyndon B. Johnson is nearly 85 percent complete. The remaining work on Johnson involves running cables, painting spaces and otherwise putting the finishing touches on the ship. The ship will then leave Bath, Maine, and head toward its home port of San Diego, California. “We're going to energize high voltage in September, lighting off the generators in the spring, then we'll be going to test and activation for the [hull, mechanical and electrical systems], trials in the fall, then delivery.” https://www.defensenews.com/digital-show-dailies/navy-league/2019/05/07/the-us-navy-is-eyeing-a-big-change-to-its-new-stealth-destroyers
