    Textron Preps For Mass Production Of New Army Rifle

    By SYDNEY J. FREEDBERG JR. WASHINGTON: Textron has partnered with global gun-maker Heckler & Koch to mass-produce new rifles for the Army and with ammunition giant Olin Winchester to churn out the high-powered yet lightweight 6.8 millimeter rounds. Textron still has to beat both General Dynamics and Sig Sauer for the right to build the Next Generation Squad Weapons (NSGW). All three companies won awards last Thursday to build prototypes for troops to test, starting this coming spring and continuing through late 2021. No follow-on production contract is guaranteed. But Textron is watching the Army's urgent push to modernize across the force, from assault rifles to hypersonic missiles and wants to be ready to sprint to mass production if it wins. Textron could do everything in house, senior VP Wayne Prender said. But, he told reporters this morning, by working with Olin Winchester and H&K, which are experienced with largescale manufacture of ammo and weapons respectively, “we are preparing ourselves for a high rate of production.” The Army wants to start fielding two variants of NGSW to tens of thousands of close combat troops — infantry, scouts, special operators, and so on — in 2022. Support troops and vehicle crews will stick with the current M4 carbine for the indefinite future. But frontline ground combatants will get more than just a gun. Linked wirelessly with electronics all over the soldier's body, including Microsoft HoloLens-derived targeting goggles called IVAS, the Next Generation Squad Weapon is meant to be just one lethal component of a larger, high-tech system. It's like the Hellfire missiles on an Apache helicopter or the 120 mm Rheinmetall smoothbore cannon on an M1 tank, except this “weapons platform” moves on foot. This approach is part of a wider push, begun by former Defense Secretary (and Marine Corps rifleman) Jim Mattis, to improve the Close Combat Lethality of the military's most exposed members. The American grunt has accumulated more and more high tech over the last two decades. Designing a new weapon from scratch is a chance to streamline the scopes, cables, batteries, and other impedimenta festooning modern foot troops. “All of those are now part of an integrated weapon system, versus a rifle that then has something else strapped onto it with wires hanging off,” Prender told reporters. “We can make some smart decisions early in the design process that enable it to be cleaner.” That should make the new weapon easier to use, lighter, and even better balanced, since the center of gravity is now calculated with installing add-ons in mind. Three Contenders, 27 Months While troops will test the first prototypes this spring, each contender has 27 months to deliver a total of 53 NGSW assault rifles — potential replacements for the M16/M4 family in service since Vietnam — and 43 automatic rifles — replacing the M249 SAW — along with 850,000 rounds of 6.8 mm ammunition. Like the M16, M4, and M249 with the 5.56 mm cartridge, the new NGSW family will all share a common 6.8 mm round, which is supposed to deliver longer range and greater body-armor-penetrating power without increasing weight much. Each competitor has their own spin on how to deliver the new rifle bullet. Sig Sauer, which already builds the Army's standard 9mm pistol and a host of other limited-issue weapons, has taken what seems to be the most conservative approach. It offers what the company calls a “hybrid” cartridge, which is still made of metal like traditional brass casings, but significantly lighter. General Dynamics's Ordnance & Tactical Systems (OTS) division has partnered with a Texan firm, True Velocity, to build “composite” rounds out of polymers. In layman's words, the bullet is packaged, not in brass, but rugged plastic. Again, the goal is to save weight. Textron's approach is arguably the most radical, to the point it doesn't even look like a bullet, just a cylinder that's equally blunt on both ends. That's because it's a cased telescoped round, sheathing the entire bullet in a polymer shell, surrounded by its propellant instead of sitting on top of it. (The resulting case looks like a folded-up telescope, hence the name). Textron says this method cuts weight per shot by 40 percent, a potential boon for overburdened foot troops. The Army's new modernization strategy — after decades of cancelled programs and incremental changes to aging weapons — is to try such great leaps forward but then test prototypes ASAP with real troops in the field. The service has been “opening the doors of the Army to the contractors to get that feedback early and often,” Prender said approvingly. Each round of user feedback is meant to help the contractors improve their product, and the military to refine their specifications, until the service can confidently choose a refined design. Now, the Army isn't locking itself in. Whoever does best in testing, the Army hasn't promised the winner a production contract. But Textron is betting they can convince an eagerly modernizing Army that their product is not only superior but ready to field without further R&D. “Whether [to] move right into an initial Low-Rate Initial Production, followed by fielding and first unit equipped, or [to do] additional prototyping and maturation of the weapon system... all that will be determined by the Army,” Prender told reporters. “We have high confidence that our weapon system will meet all of the requirements that the Army has laid out... so we're looking forward to at the end of those 27 months to move into production.” https://breakingdefense.com/2019/09/textron-readies-for-mass-production-of-new-army-rifle

    Air Force quietly, and reluctantly, pushing JSTARS recap source selection ahead

    By: Valerie Insinna WASHINGTON — Congress is waging a public battle on the fate of the JSTARS recap program, but behind the scenes, the Air Force is quietly taking steps that will allow them to award a contract for a program that leaders say they don't need. The service received final proposal revisions for the JSTARS recap program on June 22, confirmed Air Force spokeswoman Maj. Emily Grabowski in a statement to Defense News. “The Air Force wants to be postured to move forward with JSTARS recap, if required. Therefore, we are continuing source selection while we continue to work with Congress on the way forward,” Grabowski said in a statement. Usually, the government solicits final proposals and pricing information from competitors just weeks before making a final downselect. Thus, if Congress decides to force the Air Force to continue on with the program, it's likely the service will be able to award a contract in very short order. The Air Force began the JSTARS recap program as an effort to replace its aging E-8C Joint Surveillance Target Attack Radar System ground surveillance planes with new aircraft and a more capable radar. The initial plan was to buy 17 new JSTARS recap jets from either Boeing, Lockheed Martin or Northrop Grumman. However, the service announced during February's fiscal year 2019 budget rollout that it preferred to cancel the JSTARS recap program and fund an “Advanced Battle Management System” that would upgrade and link together existing aircraft and drones, allowing them to do the JSTARS mission. The Air Force's continued source selection efforts are necessary due to Congress, which is split on the issue of whether to continue to the program. Both Senate defense committees have sided with the Air Force, and would allow it to kill JSTARS recap as long as it continues to fund the current JSTARS fleet. The Senate version of the defense spending bill also includes an additional $375 million to accelerate the ABMS concept with additional MQ-9 Reapers and other technologies. Meanwhile, the House version of the bill would force the Air Force to award an engineering and manufacturing development contract for JSTARS recap to one of the three competitors, which had been valued at $6.9 billion. However, some lawmakers have said they might be willing to accept a truncated recap program to bridge the way until ABMS is fielded. “All of the committees understand the need for moving to the advanced battle management system,” Gen. Mike Holmes, head of Air Combat Command, told reporters in June. “If there are disagreements between the committees, it's about whether we can move straight to that and hold onto our legacy JSTARS as a way to bridge until we do that, or do we need to do one more recap of that system” The timing of final proposal revisions actually puts source selection for JSTARS recap ahead of that of the still ongoing T-X trainer jet program, which as of late June had not reached that stage. However, Congress will likely need time to resolve the JSTARS recap issue — meaning a contract decision is far from imminent. The House and Senate armed services committees began the conference process in June, which could allow them to reconcile differences in the defense policy bill as early as this summer. However, only appropriations bills can be used to fund government programs like JSTARS recap, and spending legislation could be stuck in limbo for months past that. If deliberations stretch out, “the Air Force will continue to assess contract award timelines and approvals. If necessary, the Air Force will request an extension of proposal validity or updated pricing as appropriate,” Grabowski said. Meanwhile, lawmakers continue to debate the case in the public eye. In a July 3 editorial for The Telegraph, Republican Rep. Austin Scott, one of the biggest proponents of the recap program, argued that it would be more economical to proceed with JSTARS recap than to continue to do extensive depot maintenance on the legacy aircraft. “After 10 years of work, the Air Force is considering canceling the JSTARS recap program,” wrote Scott, whose district in Georgia is home to Robins Air Force base, where the JSTARS aircraft reside. “Their arguments do not take into account the significantly improved capabilities and increased capacity that the new aircraft will provide. The Air Force has ignored its own assessments in their recommendation for cancellation.” https://www.defensenews.com/air/2018/07/06/air-force-quietly-and-reluctantly-pushing-jstars-recap-source-selection-ahead/
