The main thrust of the U.S. Missile Defense Agency's counter-hypersonic strategy has just been revealed.
The Regional Glide Phase Weapon System (RGPWS) prototype project demonstrates an interception capability against a medium- or intermediate-range threat.
The MDA revealed the existence of the program in a request for prototype proposals released to industry on Dec. 5. An industry day for the RGPWS prototype project is scheduled on Dec. 18 at an MDA facility on Redstone Arsenal, Alabama.
The RGPWS shows the MDA is moving faster to field at least a prototype counter-hypersonic capability than previous efforts suggested.
The MDA had previously defined a concept for a Hypersonic Defense Weapon System (HDWS). The agency selected 21 proposals from industry in September 2018 for concept definition studies. MDA then down selected to five concepts in late August and early September 2019 for a nine-month-long concept refinement phase. The selected proposals included four kinetic concepts based on existing boosters and one Raytheon-directed energy system.
The RGPWS is a parallel effort by MDA to the HDWS. The companies selected for the HDWS concept refinement phase could submit separate proposals for RGPWS. But other companies that were rejected after the concept definition phase or did not participate in HDWS can participate in the RGPWS, says Tom Karako, director of the Missile Defense Project at the Center for Strategic and International Studies (CSIS), who was briefed on the program on Dec. 9.
For example, Northrop Grumman's proposal was not down selected for the HDWS concept refinement phase, but it intends to compete for the RGPWS prototype project.
“Northrop Grumman is engaged with MDA on Hypersonic Defense Regional Glide Phase Weapon System and will attend the upcoming industry day,” a spokesman says.
Northrop has been developing kinetic and non-kinetic options for missile defense, including one concept in the latter category called the Terminal and Regional Electronic Attack Defense System.
The acknowledgment of the RGPWS offers a limited glimpse into MDA's development strategy for the burgeoning counter-hypersonic capability. In July 2017, the agency first disclosed plans for funding a hypersonic defense demonstration. An item in the Selected Acquisition Reports for the Ballistic Missile Defense System added $508 million to the program's overall budget to pay for such a demonstration. In March 2019, the agency disclosed it would spend more than $600 million on hypersonic defense capabilities by the end of fiscal 2024.
By emphasizing a “glide phase” weapon with a “regional” targeting area, the MDA also provided clues about the intent of the demonstration. It does not appear to be targeting an intercontinental ballistic missile with a nuclear hypersonic glide vehicle as the warhead, such as Russia's Avangard. It is more likely designed to target a hypersonic glide vehicle with regional range, Karako says. Options may include hypersonic glide vehicles on China's DF-17 and DF-21 missiles.
“That's a good thing,” Karako says. “It's a smart move for MDA to start there.”
Separately, the Defense Advanced Research Projects Agency continues to pursue the Glide Breaker program. It was revealed in July 2018 as a program with a particular interest in “component technologies that radically reduce risk for development and integration of an operational hard-kill system,” according to a DARPA solicitation document. But no further details about Glide Breaker have been released.

Andrew Chuter LONDON ― The British Ministry of Defence's Modernising Defence Programme, essentially a review of spending and capabilities, should start to see the light of day around the time of the July 11-12 NATO summit in Brussels. British Prime Minister Theresa May could unveil the headline conclusions of the program at the summit, with the details to follow sometime in the future. The fear is that without the government handing the military more money over the next decade, capabilities will be lost and procurement programs abandoned or delayed ― and in some instances, that is already happening. The MoD has been battling for additional cash from the Treasury for months, but with the British government announcing June 18 plans to spend billions of pounds more on health over the next few years, the chances of defense getting any significant boost appears increasingly remote. Instead the MoD will likely have to persevere with efficiency and other cuts to reduce a black hole in the 10-year equipment plan that the National Audit Office, the government's financial watchdog, said earlier this year could be unaffordable to the tune of between £4.9 billion and £20.8 billion (U.S. $5.7 billion and U.S. $24.1 billion). The parliamentary Defence and Public Accounts committees are so worried about “severe“ budgetary pressures that they took the unusual step of jointly writing to the prime minister in early June to voice their concerns. A June 18 report by the Defence Committee said that if the government wants to have the resources to keep the country safe, it “must begin moving the level of defence expenditure back towards 3% [from the current level of 2 percent] of GDP, as it was in the mid-1990s.” https://www.defensenews.com/smr/nato-priorities/2018/06/25/big-reveal-of-uk-modernization-plan-expected-in-brussels/

Analysts have criticized the program, citing the frigate design’s weight growth, scheduling delays and what they view as an inadequate number of VLS cells.
