Missile Defense Agency picks 2 vendors for hypersonic weapon tracking sensor prototypes
WASHINGTON — The Missile Defense Agency selected two companies to build prototype sensors capable of tracking hypersonic weapons from space.
L3Harris and Northrop Grumman will create the prototypes for the agency's Hypersonic and Ballistic Tracking Space Sensor. L3Harris won a $122 million award Jan. 14, while Northrop Grumman received a $155 million award Jan. 22.
In tandem with the Space Development Agency's tracking layer, the HBTSS constellation is the Pentagon's answer to hypersonic weapons, which are too dim to effectively track with current sensors in geostationary orbit and can potentially avoid terrestrial sensors. The constellation will be closer to the planet's surface in low Earth orbit, allowing sensors to more easily see the dimmer threat.
However, being closer to the Earth's surface results in a far narrower field of view for each satellite. In order to get worldwide coverage, the Pentagon is pursuing a proliferated constellation made up of dozens of satellites. SDA's tracking layer satellites will initially pick up a threat, with each satellite tracking the weapon and then passing off custody to the next satellite as the weapon leaves its field of view. Ultimately, the threat will be passed on to the more sensitive HBTSS, which can provide targeting data.
“The combination of high speed, maneuverability and relatively low altitude of some of the emerging advanced missile threats makes them challenging targets for our current missile defense systems,” the agency said in a statement. “HBTSS is needed, since we cannot populate the Earth and the oceans with terrestrial radars to meet this need. The ‘birth-to-death' tracking that HBTSS can provide when integrated with terrestrial sensors will make it possible to maintain custody of missile threats from launch through intercept regardless of location.”
Four companies were in the running to build the new HBTSS prototypes, but MDA stated on Jan. 22 that L3Harris and Northrop Grumman will be the two moving forward into the on-orbit prototype demonstration.
The other transaction authority contracts covers the prototypes through launch and early on-orbit testing. According to MDA, the prototypes should “demonstrate the sensitivity and fire-control quality of service necessary to support both the emerging hypersonic threat kill chain and dim upper-stage ballistic missiles.”

Space Force walks back stimulus contracts for small launch providers
Nathan Strout Less than two weeks after the U.S. Space Force invoked the Defense Production Act to prop up six small launch providers, those awards have been withdrawn. On June 16, the Space and Missile Systems Center announced in a beta.SAM.gov post that it was awarding rideshare contracts to six companies approved by the Industrial Base Council: Aevum, Astra, X-BOW, Rocket Lab USA, Space Vector and VOX Space. Each company was to be awarded two rideshare missions to be conducted over the next 24 months. The value of those contracts was not revealed. But as first reported by SpaceNews, SMC has withdrawn those awards. A new statement on beta.SAM.gov notes that the government “is re-evaluating its strategy on how best to proceed with this action” after receiving several responses to its decision. As a result, the contracts will not be awarded at this time. A Justification and Approval document was supposed to be made public within 14 days of contract award, but the withdrawal of the awards occurred before that deadline. While Space Force officials haven't spoken publicly about the Defense Production Act awards since they were announced online, the Pentagon was vocal in expressing concern about COVID-19 impacts on the small launch market in the months leading up to the announcement. On April 20, Undersecretary of Defense for Acquisition and Sustainment Ellen Lord stated that the small launch market was one of three sectors she was most worried about. The Space and Missile Systems Center elaborated on her remarks in a statement to C4ISRNET. “There is concern that the current financial and market constraints resulting from the COVID-19 have reduced funding sources necessary to continue development and operations for the nascent small launch industry,” said Col. Rob Bongiovi, director of SMC's launch enterprise directorate. “Much of the industry have limited flight capability or are in the critical transition from development to flight and this funding restriction may prevent or delay these systems. The Space and Missile Systems Center is evaluating the impacts to the small launch industrial base to consider actions to enable a robust U.S. launch industrial base.” Shortly thereafter, the Space Force Acquisition Council held an emergency meeting to discuss how they could support industry partners negatively impacted by COVID-19. The council ultimately sent out a survey to members of the Space Enterprise Consortium to see what industry needed from the Department of Defense. Finally on June 16, the same day the announcement went live, SMC Commander Lt. Gen. John “JT” Thompson suggested that the Space Force would use Defense Production Act awards to support the small launch market. “In the small launch environment, Secretary Lord and [U.S. Space Force Service Acquisition Executive Will] Roper have both commented about how important small launch is to our enterprise, and I can't give you the details right now but I would anticipate here very shortly some very critical Defense Production Act awards to our small launch providers to keep that industry going,” Thompson said https://www.c4isrnet.com/battlefield-tech/space/2020/07/02/space-force-walks-back-stimulus-contracts-for-small-launch-providers/
