  Missile Defense Agency picks 2 vendors for hypersonic weapon tracking sensor prototypes

  Nathan Strout WASHINGTON — The Missile Defense Agency selected two companies to build prototype sensors capable of tracking hypersonic weapons from space. L3Harris and Northrop Grumman will create the prototypes for the agency's Hypersonic and Ballistic Tracking Space Sensor. L3Harris won a $122 million award Jan. 14, while Northrop Grumman received a $155 million award Jan. 22. In tandem with the Space Development Agency's tracking layer, the HBTSS constellation is the Pentagon's answer to hypersonic weapons, which are too dim to effectively track with current sensors in geostationary orbit and can potentially avoid terrestrial sensors. The constellation will be closer to the planet's surface in low Earth orbit, allowing sensors to more easily see the dimmer threat. However, being closer to the Earth's surface results in a far narrower field of view for each satellite. In order to get worldwide coverage, the Pentagon is pursuing a proliferated constellation made up of dozens of satellites. SDA's tracking layer satellites will initially pick up a threat, with each satellite tracking the weapon and then passing off custody to the next satellite as the weapon leaves its field of view. Ultimately, the threat will be passed on to the more sensitive HBTSS, which can provide targeting data. “The combination of high speed, maneuverability and relatively low altitude of some of the emerging advanced missile threats makes them challenging targets for our current missile defense systems,” the agency said in a statement. “HBTSS is needed, since we cannot populate the Earth and the oceans with terrestrial radars to meet this need. The ‘birth-to-death' tracking that HBTSS can provide when integrated with terrestrial sensors will make it possible to maintain custody of missile threats from launch through intercept regardless of location.” Four companies were in the running to build the new HBTSS prototypes, but MDA stated on Jan. 22 that L3Harris and Northrop Grumman will be the two moving forward into the on-orbit prototype demonstration. The other transaction authority contracts covers the prototypes through launch and early on-orbit testing. According to MDA, the prototypes should “demonstrate the sensitivity and fire-control quality of service necessary to support both the emerging hypersonic threat kill chain and dim upper-stage ballistic missiles.” https://www.c4isrnet.com/battlefield-tech/space/2021/01/25/missile-defense-agency-picks-two-vendors-for-hypersonic-weapon-tracking-sensor-prototypes

  US Army confident any tech schedule slips are recoverable

  By: Joe Gould WASHINGTON — The U.S. Army is girding for modernization program delays and a rise in acquisition costs as the coronavirus pandemic ripples across its installations and through its network of suppliers. Army leaders told reporters Thursday they are confident the service can juggle schedules to make up for any emerging delays and would ask Congress to help address future cost growth. While some larger prime contractors have adapted quickly, officials said, they warned that lower-tier companies with less slack in their workforces remain vulnerable. The Army's Integrated Air and Missile Defense Battle Command System had several major tests and evaluations scheduled, including a long-awaited limited-user test, or LUT. However, Army Futures Command chief Gen. Mike Murray said in a call with reporters that the testing schedule “will slide a little bit, but we will be on time” for the program's other milestone decisions. “I am very confident we will get the LUT done this summer or early fall,” he said. The Army is in the third year of an ambitious modernization overhaul, which depends in part on “soldier touchpoints,” or user evaluations of new equipment. The modernization efforts are now in question as commanders apply physical distancing measures to protect their soldiers. For example, a touchpoint at Fort Riley, Kansas, for a future replacement of the RQ-7 Shadow unmanned aircraft system is going ahead, but the commander at Fort Campbell, Kentucky, decided to postpone one there. Whether wider program delays are coming, “we're still watching very closely, and what I am very much focused on is there may be some slips in key decisions and soldier touchpoints,” Murray said. “The current estimate is we will deliver that [UAS] capability to our soldiers by the time we said we would.” The Army will also push a critical touchpoint for the Integrated Visual Augmentation System from the summer to the fall after Microsoft — a subcontractor for the prime — temporarily closed. The device is a set of goggles meant to provide soldiers next-level night and thermal vision as well as enhance navigation and targeting. “Not only for that program but for all our programs, input from the soldiers that were actually asked to use this equipment has been critical,” Murray said. “That has been impacted.” The comments came as the Pentagon expects a broader three-month delay for major acquisition programs and speeds progress payments to primes that should trickle to small businesses. Army acquisitions officials have worked to help get second- and third-tier suppliers access to small business loans as well as facilitate cash flow to them. “The supply chain does have some challenges, and that's probably where the vast majority of any slips would occur that are tied to individual companies,” said Bruce Jette, the Army's acquisition chief. “These companies are small, and if one person gets COVID in the company, the next thing you know you've lost 14 days with the company because everybody that didn't get it is in quarantine.” BAE Systems coordinated a temporary closure with the Army and plans to scrap a planned summer break to make up the time. Boeing's closure in Philadelphia also came and went. “It's like that down [the] chain for the primes: They tend to be coming back online,” Jette said. “The ones where we end up with two or three weeks are the ones where we've got small individual companies of maybe 20 to 30 people who were suppliers of cables, or connectors and things like that. “There's something there that tends to have a bigger impact or take a little bit longer time. And with them, we try to execute those portions of the program which aren't dependent upon those components, and then we'll come back and clean up the battlespace.” Some big agenda items for the Army don't appear to have been knocked off balance. For example, the Army is still planning on another flight test of Lockheed Martin's Precision Strike Munition, or PrSM, by April 30, which will deliver a new long-range precision fires capability to the battlefield. The capability is the Army's No. 1 modernization priority. “I'm confident enough that we're going to do the next test flight [of] PrSM that I scheduled a military aircraft to go out and see it, so I'm very confident,” Murray said. The Army's latest “night court” review — used to divest the service of unneeded programs — proceeded virtually, as much of the Pentagon shifted to remote work. As part of the review, Army leaders recently received the final brief concerning equipment. “A lot of the recommendations are pretty much close to being finalized,” Murray said. https://www.defensenews.com/land/2020/04/23/us-army-confident-any-tech-schedule-slips-are-recoverable/

  US buys additional 248 JLTVs from Oshkosh

  By: Aaron Mehta WASHINGTON — The U.S. government has placed a new $127 million order for 248 Joint Light Tactical Vehicles from Oshkosh, the company announced Wednesday. The award would provide JLTVs for the U.S. Army, Marine Corps and State Department. “The JLTV was designed to provide our troops with unmatched mission capabilities,” George Mansfield, vice president and general manager of joint programs for Oshkosh Defense, said in a statement. “And while adversaries, terrains, and tactics have all evolved immensely since the vehicle's conception, the JLTV's flexible design allows the light tactical vehicle fleet to evolve at a similar pace.” This contract is the third order placed in the last seven months for JLTV production. A $407.3 million package for 1,240 vehicles to the U.S. Marine Corps, Slovenia and Lithuania was awarded in February. In December, the company received a $803.9 million award for 2,721 vehicles for the American military and ally Montenegro. Oshkosh beat out Humvee-maker AM General and Lockheed Martin in 2015 to build the replacement for the Humvee for both the Army and the Marine Corps. The low-rate initial production contract was worth $6.7 billion, and the entire program is estimated to be worth $30 billion through 2024. Since a production contract was awarded in 2015, Oshkosh says it has delivered 7,500 total vehicles to the U.S. and partners abroad. In its fiscal 2021 budget request, the Army asked for $894.4 million to buy 1,920 JLTVs. However, that number is down from what had initially been projected by the service; as part of the “night court” process, designed to reprioritize the service's investments and projects, the Army is stretching its planned JLTV buy out in order to reinvest dollars to modernization priorities. https://www.defensenews.com/land/2020/07/01/us-buys-another-248-jltvs-from-oshkosh/
