Lockheed Martin’s SPY-7 Radar Is Going to Sea

Posted on February 5, 2021 by Richard R. Burgess, Senior Editor

ARLINGTON, Va. — Lockheed Martin's new SPY-7 radar will be sailing to sea on the ships of three navies as the company highlights the radar's capabilities for application to other navies, including the U.S. Navy.

The SPY-7, which uses gallium nitride modules, initially was developed for the Navy's Air and Missile Defense Radar competition. It was adapted into the Long-Range Discrimination Radar (LRDR) procured by the U.S. Missile Defense Agency (MDA) as a sensor of the Ground-Based Midcourse Defense system. Being installed at Clear Air Force Station in Alaska, the LRDR is designed to discriminate between incoming warheads and decoys.

The core building blocks [of the LRDR] are the same core building blocks in SPY-7,” said Jon P. Rambeau, vice president and general manager, Integrated Systems & Sensors, Lockheed Rotary and Mission Systems, during a Feb. 2 interview with Seapower. “[SPY-7] is a modular radar that allows us to build different configurations for both land-based and sea-based applications.”

The SPY-7 has been selected by the Spanish navy to integrate it with the Aegis Combat System on its F110 frigates. The Canadian navy is procuring the radar to install it on its new Halifax-class surface combatant.

Japan had selected the SPY-7 for its two planned Aegis Ashore ballistic-missile defense sites, but when the plans were cancelled in part out of concern for missile debris falling on populated areas, Japan shifted to a plan to deploy the SPY-7 on some future, unspecified sea-based BMD platform. Japan already has BMD capabilities in its Kongo-class guided-missile destroyers with Aegis systems using the SPY-1 radar.

Japan, which already has placed an order for the SPY-7, “is going through a process now to determine exactly what that platform is going to look like,” Rambeau said. “We are pleased with the progress that the technology has made, and we're starting to see some uptake both here in the U.S. as well as abroad.”

“SPY-7 is part of the Aegis common source library (CSL) and the interfaces are understood,” said Patrick W. McNally, director of communications for Integrated Warfare Systems & Sensors, in a statement to Seapower. “For Japan, we have completed the first of three releases which were recently demonstrated to MDA. Starting from the CSL, with over one million lines of code, Japan will be receiving the best of both Baseline 9 and 10 [Aegis software].”

The U.S. Navy is considering backfitting some Flight IIA Arleigh Burke-class guided-missile destroyers with a radar more modern than the SPY-1, and Lockheed is keeping a watch on developments in the event the SPY-7 could complete in the program if it comes to pass.

Rambeau said his company also “has some more affordable options available to upgrade some of the SPY-1 arrays to provide improved sensitivity and improved resistance to electronic attack and we think we can do that at a fraction of the cost of a wholesale replacement, so we've put forth a couple of options for upgrades to SPY-1 to both MDA and the Navy.”

    The next GPS payload will be fully digital

    By: Nathan Strout The navigation payload for the next iteration of GPS satellites has passed its critical design review, contractor L3Harris announced Feb. 11. According to the company, which is designing and building the system, the new payload will provide a more powerful, reliable and flexible GPS signal than previous satellites.The GPS IIIF satellites will follow the first 10 GPS III satellites—the first of which is already on orbit and operational. The Air Force plans to eventually build 22 GPS IIIF satellites. While the GPS III satellites use a 70 percent digital Mission Data Unit, the one in the new GPS IIIF payload will be fully digital. According to L3Harris, the new system will “provide more powerful signals and ensure flawless atomic clock operations.” “The digital payload is flexible enough to adapt to advances in GPS technology and future warfighter mission needs,” said Ed Zoiss, president of L3Harris' space and airborne systems. “Proceeding to the next stage in the GPS IIIF navigation payload development process moves the program closer to supporting evolving Air Force mission requirements.” With the critical design review complete, L3Harris can move forward with final development, test and delivery. The company has contributed navigation technology to every GPS satellite in orbit. While L3Harris is designing the navigation payload, Lockheed Martin is the prime contractor for GPS IIIF. The Air Force awarded Lockheed Martin more than $1.3 billion to build the first two GPS IIIF satellites in 2018. Critical design review for the platform is expected in March 2020, according to Space Force budget documents released Feb. 10. Once that is complete and the program passes Milestone C in the third quarter of FY2020, the Space Force will begin procuring additional GPS IIIF satellites with annual contract options. Delivery of the first GPS IIIF satellite is expected in 2026. Among their advanced features, GPS IIIF satellites will boast regional military protection capabilities, which allow them to deliver regionally-limited high-power M-Code signals. It will also include new laser retro-reflector arrays that can provide on orbit position determination. Furthermore, the GPS IIIF satellites are being designed to potentially incorporate technology from Navigation Technology Satellite 3, an Air Force Research Laboratory space vehicle that will be used to test a variety of position, navigation and timing technologies. L3 Harris is the prime contractor on that program, which recently passed its preliminary design review. https://www.c4isrnet.com/battlefield-tech/space/2020/02/12/the-next-gps-payload-will-be-fully-digital/

    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
