A new hypersonic weapon concept has emerged inadvertently on a social media page managed by U.S. Army Secretary Ryan McCarthy that describes a Mach 5-plus projectile with the ability to penetrate into defended airspace and dispense a multi-role loitering air system over a target area.
The concept—labeled as the Vintage Racer Loitering Weapon System—reveals a solution to an operational problem for the Army: When high-speed munitions, such as the Long-Range Hypersonic Weapon (LRHW), enter service with the ability to strike targets thousands of kilometers away, how will the Army find the most elusive targets, such as road-mobile launchers for intercontinental ballistic missiles (ICBM) or radars for air defense batteries?
The Vintage Racer concept, as revealed so far, suggests it may be possible to launch a hypersonic projectile into a general area without knowing the specific location of the target. As it reaches the target area, the projectile may be able to dispense a loitering air system, which is then uses its own sensors to find and identify the target. If the loitering system also carries a warhead, it may be able to strike the target by itself or transmit the target coordinates to another weapon.
Once the existence of the Vintage Racer concept appeared, a Russian expert on military-political affairs noted such an idea has been discussed as a possibility within the hypersonic weapon community.
“The fear is that [this] hypersonic ‘something' might reach the patrol area of road-mobile ICBM launchers [after] penetrating any possible air and missile defense, and then dispense loitering submunitions that will find launchers in the forests,” said Dmitry Stefanovitch, an expert at the Moscow-based Russian International Affairs Council.
Only the broadest information about the Vintage Racer weapon is visible on the briefing paper describing the concept.
The image appears in an album of photos from the Association of the U.S. Army convention posted to McCarthy's Flickr account last October. Most of the pictures from the event show McCarthy meeting attendees, giving speeches and receiving informal, standing pitches from industry officials in the exhibit hall.
One picture shows McCarthy standing at a table across from an unidentified industry official in the exhibit hall. The table is covered with multiple objects, including a General Atomics press release, what appears to be a model of the LRHW and a rifled barrel of a 155mm artillery gun with a hole burned through the object.
The table also is covered with at least four sheets of briefing papers, of which three are not visible. The only visible paper, which is partly obscured by McCarthy's right hand, is headlined “Vintage Racer - Loitering Weapon System (LWS) Overview.” The paper includes six main bullet points, which read “Hypersonic Ingress,” “Survivable,” “Time Over Target,” “Multi-role,” “Modular payload,” and “Cost Imposition Strategy.” Ten sub-bullets are also visible on the page, but the letters are not readable.
At the bottom of the page, a tag line highlighted in yellow is partly obscured by McCarthy's hand, but the visible portion reads: “Long Range, Rapid Ingress.”
A vague reference to Vintage Racer previously appeared in Defense Department budget justification documents released in February, but went unnoticed. Under a line item owned by the Office of Secretary of Defense for a “quick reaction fund,” Vintage Racer is described as a “recent success story.”
“The project successfully validated aerodynamic design with wind tunnel testing and integrated a guidance subsystem for targeted kinetic effects before culminating in a fiscal 2019 flight test. Documentation and prototype technologies transitioned to the U.S. Army for additional development and follow-on acquisition activities,” according to budget documents.

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.” https://seapowermagazine.org/lockheed-martins-spy-7-radar-is-going-to-sea
