Integrated Hypersonic Plan Forms Amid Overlap Concerns

WEST LAFAYETTE, Indiana—The U.S. Defense Department says data from an upcoming four-year test campaign covering 40 flights and three basic vehicle concepts will lay the foundation for a comprehensive hypersonic weapon road map that should allay growing congressional concerns over potential overlaps in costly weapons development capability.

To a quarter of the tests, representing as many as 10 flights, will be focused on air-breathing scramjet-powered vehicles, says Mike White, assistant director for hypersonics at the Office of the Under Secretary of Defense for Research and Engineering. Speaking to Aerospace DAILY on the sidelines of the inaugural National Defense Industrial Association (NDIA) hypersonics capability conference at Purdue University here, White says test results from both boosted glide vehicle flights and powered missiles will form the basis for the integrated development plan.

The overarching road map also will include the integration of a counter hypersonic development strategy, the preliminary steps toward which have been proposed by both the recently formed Space Development Agency (SDA) and the Missile Defense Agency. The SDA is studying a space-based distributed satellite architecture, while the latter has proposed a Hypersonic and Ballistic Tracking and Surveillance System (HBTSS). “Offensive and defensive coordination is my job,” White says.

The bulk of the prototype tests will be conducted using the common hypersonic glide body (C-HGB). Developed by Sandia National Laboratories, the bi-conic re-entry vehicle has been adopted as the basis for near-term boosted glide weapons by the U.S. Air Force, Army and Navy, with only minor differences in each version planned to reflect the varying operational characteristics of each role.

The Army, which plans to ground launch the Long-Range Hypersonic Weapon (LRHW) from transporter erector vehicles, is meanwhile making the first moves toward industrializing production of what up to now has been small batch manufacturing runs of experimental vehicles. The service has issued a solicitation for transition of the design and production capability of the initial prototype LRHW C-HGB variant out of Sandia into industry. A contract award is expected to be issued this month.

Other versions of the C-HGB are in development for the Navy's vertically launched Intermediate Range Conventional Strike Weapon (IR-CPS), and the Air Force's Hypersonic Conventional Strike Weapon (HCSW). Underwater launch tests of the IR-CPS, which follows the successful Flight Experiment-1 test in October 2017, from the Pacific Missile Range Facility in Kauai, Hawaii, are due to run through 2024. The Air Force is scheduled to complete critical design review of the HCSW in 2020 prior to launch tests from a B-52.

At least five other flight-test campaigns make up the remainder of the hectic four-year plan, three of which will be focused on the DARPA-led Tactical Boost Glide (TBG) vehicle and two proposed follow-on air-launched rapid response weapon (ARRW) vehicles in competitive development by Lockheed Martin and Raytheon. The balance are two air breathing vehicles, also in development by Lockheed/Aerojet Rocketdyne and Raytheon/Northrop Grumman, which will be evaluated under the Air Force's Hypersonic Air-Breathing Weapon Concept (HAWC) program.

Despite the ongoing efforts to refine the hypersonic road map, the proliferation of prototype vehicle programs continues to cause concern in Congress. Warning that not all programs will receive the funding requested in the fiscal 2020 budget, Peter Visclosky, chairman of the House Appropriations Subcommittee on Defense, says some reductions are planned. Commenting at the NDIA event, he says, “Justifications in the budget for this effort receive the same scrutiny as every other program in the department and unfortunately certain aspects of that 2020 budget request were lacking.”

Without identifying particular initiatives, Visclosky adds, “There were cuts to those specific programs where the justifications did not lead to a review. Each of the services impacted have been made aware of the issues that the committee has raised and the need to better define the strategy for the investment in these systems.”

Visclosky also cautions that hypersonics, which is provisionally funded with a budget of $2.3 billion for fiscal 2020 and $10.5 billion over the period to 2024, also faces broader threats at a time of increased spending on other high-profile defense programs. “I am concerned about affordability in the future because this is a competitive process,” he said. “We have a nuclear modernization process that is underway and there is going to be a bulge in the federal budget. There is a new submarine and there is going to be a bulge in the budget. It is the same for the new [B-21] bomber under development and, while the Army doesn't have that ‘one' new program, collectively for the modernization program there is going to be one.

“We need to make sure there is a concerted effort for commonality and collaboration to a common technical standard and system architecture. I think this will drive better affordability into the sustainment of the system,” he adds.

The Army’s SAW and M4 replacement is headed to troops by 2022
Todd South The gun that will replace both the M249 Squad Automatic Weapon and the M16/M4 rifle/carbine weapons — and add a new, widely distributed caliber to the U.S. military inventory for the first time in decades — is less than two years away. The Next Generation Squad Weapon finished its first prototype test event in September. The three previously selected offerings came from Sig Sauer, Textron Systems and General Dynamics Ordnance. Brig. Gen. David Hodne, Infantry School commandant and Soldier Lethality Cross Functional Team director, along with Brig. Gen. Anthony Potts, head of Program Executive Office Soldier, gave updates to Army Times ahead of the Association of the U.S. Army Annual Meeting and Exposition. Concurrently, the Army in April has also selected two companies, L3 Technologies and Vortex Optics, to compete for the fire control for the weapons system. Sig Sauer's design looks much like a conventional assault rifle while GD is using a bullpup design, which shortens the length by building the magazine feed into the weapon stock. Textron has built its weapon around the cartridge, which is unique to them, a cased telescope item that has the projectile inside of the casing to reduce weight. Back in April, each of the companies provided 15 rifles, 15 automatic rifles and 180,000 cartridges using the government-developed 6.8mm projectile. The 6.8mm projectile was chosen after decades of testing and evaluation showed that 5.56mm lethality at mid-ranges on the battlefield was inadequate and existing 7.62mm could be outperformed by the 6.8mm round and save weight for the soldier. The new caliber also gives the soldier both a rifle and automatic rifle firing the same round, both effective past the 600m mark of existing light calibers. Following the September testing, the companies will have six months until their next prototype test, scheduled to begin in February. During the annual Maneuver Warfighter Conference at Fort Benning in Georgia, Maj. Wyatt Ottmar, project officer over NGSW for the Soldier Lethality CFT, laid out some of the recent developments and next steps for the weapons system. Ottmar noted that Sig Sauer provided a combined steel lower and brass upper ammunition cartridge to reduce weight. A contract is expected to be awarded to one of the three companies this coming fiscal year with fielding to start in the fourth quarter of fiscal year 2022, or sometime between August and October 2022, to Infantry, Stryker and Armor Brigade Combat Teams. Ultimately, the weapon will be fielded to all close combat forces, including special operations forces, infantry, combat engineers and scouts. The fire control is expected to field six months ahead of the weapon, Potts said. That will allow the NGSW producer to better integrate the optic with the weapon. https://www.defensenews.com/news/your-army/2020/10/14/the-armys-saw-and-m4-replacement-is-headed-to-troops-by-2022/
