An early version of the Senate's annual defense bill would provide additional funding for space-based sensors capable of detecting and tracking hypersonic weapons, according to a summary released June 11. However, details on the proposal are scant.
Congress has become increasingly concerned over the threat posed by hypersonic weapons under development by China and Russia. Too dim to be reliably picked up by current space-based sensors and able to maneuver around terrestrial sensors, hypersonic weapons make much of the current missile warning system obsolete, as it was designed for ballistic missile threats.
To counter this threat, the Defense Department has proposed a solution: a proliferated constellation of satellites operating in low Earth orbit. Once a hypersonic threat is detected, the constellation tracks it while passing custody from satellite to satellite as the weapon moves around the globe.
This Hypersonic and Ballistic Tracking Space Sensor, or HBTSS, will be part of the new National Defense Space Architecture, a proliferated constellation that will eventually be made up of hundreds of small satellites operating primarily in low Earth orbit. The Space Development Agency is overseeing this effort and plans to begin placing its first satellites on orbit in fiscal 2022.
The Missile Defense Agency listed HBTSS as an unfunded priority during the prior budget cycle, and ultimately Congress did allocate $108 million to the agency for the program in FY20. Now the Senate Armed Services Committee says it will provide additional funding for the program for FY21, but it has yet to say by how much.
The summary also does not note where the funding for HBTSS will go. Determining which agency would be in charge of HBTSS was a source of friction between the Pentagon and Congress in 2019, with the latter pushing for MDA to take primary responsibility for the effort, while the White House claimed it was too early to put one agency in charge.
Ultimately, legislation passed by Congress in December directed MDA to be the lead agency for the development and deployment of HBTSS. However, the Missile Defense Agency's proposed FY21 budget transfers HBTSS funding responsibility to the Space Development Agency.
At the same time, MDA awarded four $20 million contracts to companies to develop HBTSS prototypes in October. The four companies selected were Northrop Grumman, Leidos, Harris Corporation and Raytheon. The SDA recently issued a request for proposals for wide field of view satellites that references medium field of view satellites which are expected to be launched in 2023. According to SDA Director Derek Tournear, those will be the first space components of MDA's HBTSS.
Still, it's unclear whether Congress will endorse moving HBTSS funding responsibility to SDA in FY21.
When faced with criticism over that move from legislators at a March hearing, MDA Director Vice Adm. Jon Hill assured them that his agency would remain in charge of sensor development for HBTSS, with SDA providing money to MDA for the effort. Hill said the decision to move the funding was made by Under Secretary of Defense for Research and Engineering Michael Griffin
SDA is asking for $137 million for space technology development in FY21, which includes funding for space sensor technology. The agency expects to begin placing payloads on orbit in FY22. The budget request does not specifically break out funding for HBTSS.
MDA has also asked for $207 million for hypersonic defense. That funding will help the agency develop a regional glide phase weapon system and maturing technologies for future hypersonic defense architectures. It does not include funding specifically for HBTSS, as that has transitioned to SDA.
CORRECTION: This story has been corrected to show that the medium field of view satellites are not part of the SDA's wide field of view solicitation.

By: Jen Judson WASHINGTON — The U.S. Army has picked an Oshkosh Defense and Flyer Defense LLC team, an SAIC and Polaris team, and GM Defense to competitively build Infantry Squad Vehicles intended to provide ground mobility for infantry brigade combat teams. Each industrial choice was awarded an OTA, or other transaction authority, task assignment under the National Advanced Mobility Consortium to deliver and test two prototypes each, said Steve Herrick, ground mobility vehicle product lead with the Army's Program Executive Office Combat Support & Combat Service Support, in a statement sent to Defense News. OTA is a congressionally authorized contracting mechanism meant to expedite prototyping efforts. The three received $1 million to build the vehicles and it's expected that the Army will take delivery of the prototypes on Nov. 13 at Aberdeen Test Center, Maryland. The prototypes will be evaluated in various performance, operational and characteristics tests through the end of the year and will then be transported to Fort Bragg, North Carolina, in January to be assessed by soldiers, Herrick said. Each industrial choice is expected to simultaneously deliver information to the Army on price, production and logistics. The Army will choose one vehicle for production in the second quarter of fiscal 2020 based on soldier feedback and response to a formal request for proposals leading to production. The Army Requirements Oversight Council approved an Army procurement object for 649 Infantry Squad Vehicles with an objective requirement of 2,065 ISVs in February. The ISV is intended to supplement and potentially replace vehicles the Army procured as version 1.1 of the Ground Mobility Vehicle. The ISV “is additive” to infantry brigade combat teams “and currently not planned as a replacement for current vehicles in the formation,” according to Herrick. Oshkosh and Flyer, in a way, represent the incumbent, as Flyer produced the GMV 1.1. vehicle currently fielded. Flyer Defense “is the design authority” and will lead the team in building the prototypes, according to a statement from the team. GM Defense's ISV is based on its Chevrolet Colorado midsize truck and its ZR2 and ZR2 Bison variants, according to a company statement, “supplemented with both custom and commercially available parts proven by Chevy performance engineering in more than 10,000 miles of punishing off-road development and desert racing in the Best of the Desert Racing series.” The SAIC-Polaris team is submitting the DAGOR vehicle, which “delivers off-road mobility while meeting the squad's payload demands, all within the weight and size restrictions that maximize tactical air transportability,” according to Jed Leonard, vice president of Polaris Government and Defense. The DAGOR ISV “will leverage and further enhance the already proven, production-ready solution that has been tested, certified and fielded to operational units in the U.S. Military and its Allies since 2015,” Leonard added. The prototype competition is a significant step toward a solution after years of uncertainty; the Army seemed geared toward holding a rapid competition to buy a GMV in 2016, but the plan was delayed without much explanation in favor of buying an interim vehicle already in use by special operations forces. Buying the GMV was a top priority following the fall 2015 release of the Army's Combat Vehicle Modernization Strategy, which called for such a vehicle in future and current operations. But when a competition never materialized, rumors swirled that the Army might buy more of U.S. Special Operations Command's GMVs — General Dynamics Ordnance and Tactical Systems' Flyer 72 — even after the service had spent several years testing a wide variety of commercial off-the-shelf options. The Army bought quantities of the command's vehicle for five airborne infantry brigade combat teams. Congress spurred the effort in its FY18 defense policy bill, mandating the Army hold a competition and move forward with a program. PEO CS&CSS' product lead for the GMV stated on its website that the Army planned to pursue a competition for the GMV — calling it an ISV — as a formal program of record late last year. The office also released a market survey asking for a vehicle that provides mobility for a nine-soldier infantry squad as well as associated equipment to “move around the close battle area.” The vehicle should be lightweight, highly mobile and transportable “by all means” to include CH-47 Chinook cargo helicopters, UH-60 Black Hawk utility helicopters, and via low-velocity airdrop. https://www.defensenews.com/land/2019/08/28/us-army-picks-3-teams-to-build-infantry-squad-vehicle-prototypes
