  Raytheon Unveils Medium-Range Air-to-Air Missile Project

  Steve Trimble Raytheon has unveiled an internally funded program to develop a new air-to-air missile called Peregrine that combines the reach of the medium-range AIM-120 and the maneuverability of the short-range AIM-9X, but in a smaller form factor to increase the magazine depth of tactical aircraft. The unveiling of a Peregrine mockup on Sept. 16 at the Air Force Association's annual National Convention in Washington comes just three months after U.S. Air Force officials confirmed the ongoing development of the Lockheed Martin AIM-260, which is intended to replace the AIM-120 with a longer-range missile of the same length. The Peregrine missile is being pitched to U.S. and international customers that want AIM-120 performance in a smaller package to double missile loads in the internal weapon bays of stealth fighters or triple the magazine depth on the external weapon stations of nonstealth aircraft, says Mark Noyes, vice president of business development and strategy for Raytheon Missile Systems. “What we see it as is a complement to our [AIM-120] Amraam and AIM-9X,” Noyes says Raytheon's internal development project follows the introduction of multiple weapons boasting longer range than the nearly three-decade-old AIM-120 design. In addition to the MBDA Meteor, the PL-15 is being developed by China and the Vympel K-77M has been ordered by the Russian government. The Peregrine also fits into a new category typified by the 2013 unveiling of Lockheed Martin's Cuda concept, which offered the Air Force a missile with AIM-120-like range—or slightly better—in a package half the size and weight. The Cuda received support from an Air Force Research Laboratory project called Small Advanced Capabilities Missile. Raytheon lists the Peregrine with a length of 6 ft. (1.8 m) and a total weight of about 150 lb. (68 kg), or roughly half the length and mass of the 12-ft., 335-lb. AIM-120. Although Peregrine shares a common stature with Lockheed's Cuda concept, there are distinct differences. Lockheed designed the Cuda as a hit-to-kill weapon, but the Peregrine destroys the target with a blast-fragmentation warhead. The missile is guided to the target with a “multimode autonomous seeker,” says Noyes, but he declined to elaborate. A multimode guidance system places the Peregrine in a different category than the radar-guided AIM-120 and infrared homing AIM-9X. It could more closely reflect the multimode guidance system installed in the Raytheon/Rafael Stunner surface-to-air missile, which combines radar and infrared sensors into a dolphin nose-shaped radome. A “new, high-performance propulsion section” will accelerate the Peregrine to supersonic speed to achieve potentially slightly better range than the AIM-120, but Noyes declined to describe the specific type of propulsion technology selected for the new missile. Several options are available to modern missile designers. The Stunner uses a multipulse rocket motor, while the MBDA powers the Meteor missile with a ramjet-augmented rocket. Missile developers also have been experimenting with new propellant technologies, including exotic gels. Even at a range equivalent to that of the AIM-120, the Peregrine should provide similar endgame maneuverability as the super agile AIM-9X, Noyes says. “It will go supersonic and that's attributable to that new lightweight airframe and high-performance modular control system,” he says. “That permits it [to] go and do incredible maneuvers, especially at the endgame where it's needed most.” How long Raytheon has been developing the Peregrine is not clear. In a blow to Raytheon's hopes to deliver the successor of the AIM-120, the Air Force awarded the AIM-160 development contract to Lockheed in 2017. Raytheon filed a trademark application for a new guided missile called Peregrine on Aug. 14, 2018. The company is testing components and is “seeing tremendous progress,” Noyes adds. “We are making a commitment to mature this so our service customers will resonate with its capabilities and demonstrated performance,” he says. https://aviationweek.com/defense/raytheon-unveils-medium-range-air-air-missile-project

  Army to Receive 7.62mm Squad Marksman Rifles as Early as Next Year

  By Matthew Cox Heckler & Koch Defense Inc. will soon begin delivering thousands of 7.62mm squad-designated marksman rifles to the Army to give infantry and other close-combat units a better chance of penetrating enemy body armor. H&K will deliver "between 5,000 and 6,000" variants of the G28 rifle, which the Army plans to issue as its new squad designated marksman rifle (SDMR), according to a July 12 H&K news release. Under the agreement, the rifles will be manufactured by H&K in Oberndorf, Germany, and will begin to arrive in the H&K-USA facility in Columbus, Georgia, early next year, according to the release. Once there, H&K-USA workers will install scopes and mounts purchased by the Army under a separate agreement. "This is a significant achievement for Heckler & Koch," H&K-USA's chief operating officer, Michael Holley, said in the release. "The HK SDMR system will add much-needed capabilities to virtually every squad in the Army. We are honored by this opportunity." The new SDMRs are part of an interim effort to make squads more lethal ahead of the Army's fielding of the Next-Generation Squad Weapon system sometime in 2022, service officials have said. In May 2017, Army Chief of Staff Gen. Mark Milley told Senate Armed Services Committee members that the service's current M855A1 Enhanced Performance Round will not defeat enemy body armor plates similar to the U.S. military-issue rifle plates such as the Enhanced Small Arms Protective Insert, or ESAPI. As a short-term fix, the Army selected the G28 as its M110A1 Compact Semi-Automatic Sniper System in 2016, to be used with the service's new 7.62mm enhanced performance round to give squads more penetrating power. In the past, the Army relied on the Enhanced Battle Rifle, or EBR, 14 -- a modernized M14 equipped with an adjustable aluminum stock with pistol grip, scope and bipod legs -- to fill the growing need by infantry squads operating in Afghanistan to engage enemy fighters at longer ranges. But the EBR is heavy, weighing just under 15 pounds unloaded. The M110A1 weighs about 11 pounds. In the long term, the Army is working with gunmakers to develop the new Next Generation Squad Weapon (NGSW) that is slated to fire a special, government-produced 6.8mm projectile that promises higher velocities at greater ranges, service officials say. The program is being designed to produce an automatic rifle version to replace the M249 squad automatic weapon and a carbine version to replace the M4 carbine. Army officials said recently that they expect to begin receiving prototypes of the NGSW in July and August and that the weapon could be fielded to units beginning in late fiscal 2020. https://www.military.com/daily-news/2019/07/12/army-receive-762mm-squad-marksman-rifles-early-next-year.html
