U.S. Army Flickr Page Inadvertently Reveals New Hypersonic Weapon Concept
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.

Next F-35 Contracts Under Negotiation, Deal Expected by Late September
Jan. 22, 2021 | By John A. Tirpak The F-35 Joint Program Office, Lockheed Martin, and Pratt & Whitney are negotiating prices for the 15th through 17th lots of Lightning II fighters and engines, aiming for a deal by the end of September. The contracting strategy is to negotiate a “base year” contract for Lot 15, with “two single-year options (Lots 16 and 17),” a JPO spokeswoman said. While the air vehicles are under negotiation, the “propulsion Lot 15-17 proposal is currently in technical evaluation,” the spokeswoman said. Although Lockheed quotes prices publicly for F-35s with engines included, the government negotiates with the engine maker separately. The Lightning II is powered by Pratt's F135 turbofan. The strategy likely buys time for the F-35 to finally exit engineering and manufacturing development and be declared ready for full-rate production, a milestone postponed last month for the third time by former Pentagon acquisition and sustainment chief Ellen Lord. The Lot 15-17 contracts will also mark the first major deals for the F135 engine conducted with Pratt under the ownership of Raytheon Technologies, which formally took over the engine maker in April 2020. Pratt was previously owned by United Technologies. The program office expects to conclude both the air vehicle and propulsion talks within fiscal 2021, the spokeswoman said. Lot 15 air vehicles “are planned to be fully funded and awarded in FY'21,” but the Lot 16 and 17 options would be exercised in fiscal year 2022 and 2023, respectively, “when funding becomes available.” The Lots 15-17 contracts were originally expected to include a multi-year “block buy” agreement including the U.S. However, by law, the U.S. cannot enter into a multiyear procurement arrangement for a weapon system until it has passed Milestone C, or full-rate production. The F-35 most recently was supposed to clear Milestone C in March, but Lord postponed that declaration until further notice, due to ongoing challenges integrating the F-35 with the Pentagon's Joint Simulation Environment—a wargaming system that helps Pentagon leaders decide on optimum force sizes for various weapon platforms. Lord's move leaves it up to the Biden administration to declare whether and when the F-35 is ready for full-rate production. When the Lot 12-14 contract was announced in October 2019, Lord said the F-35 had completed 90 percent of the tasks necessary to pass Milestone C. U.S. partners in the F-35 program are already participating in a “block buy” arrangement with Lockheed Martin. The $34 billion October 2019 contract, which covered Lots 12-14, achieved Lockheed and the JPO's longstanding goal of getting the unit cost of the F-35A below $80 million a copy. That contract, the largest yet for the fighter, included 478 aircraft; 291 for U.S. military services and 127 for foreign users. It also marked a 12.8 percent drop in the price of the Air Force version of the Lightning II over Lot 11. Engine costs had only declined 3.5 percent versus the previous lot. Lots 15-17 will likely involve a slightly larger number of aircraft. Industry officials said they expect smaller cost reductions in the F-35 from now on, as the production line is nearly at capacity and peak efficiency. The 2019 contract was the “big bang” deal, said one, in which Lockheed “pushed it” to get the unit cost below $80 million. At that price, the fifth-generation F-35 costs less than fourth-generation types like the F-15EX, but its operating cost remains significantly higher. Lockheed missed its delivery quota of F-35s in 2020 by about 20 airplanes, due to delays incurred by the COVID-19 pandemic. Michele Evans, former Lockheed aeronautics vice president, said in the fall the company expects to gradually make up those missed deliveries by around 2023, noting it did not want to disrupt the production enterprise for a brief surge to get back to par. https://www.airforcemag.com/next-f-35-contracts-under-negotiation-deal-expected-by-late-september
