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.”

Le portefeuille de participations financières de l'État dans l'aéronautique et la défense a été peu affecté par la crise sanitaire, selon la Cour des comptes
La Cour des comptes révèle, dans un rapport publié dimanche soir et consacré à la gestion des participations financières de l'État durant la crise sanitaire, que l''impact de celle-ci sur le patrimoine de l'État dans le secteur de l'aéronautique et de la défense a été très limité. Ce secteur « a bien résisté à la crise en se maintenant à une valeur globale de 8,4 Md€ », indique le rapport. L'évolution du portefeuille de participations financières de l'État dans l'aéronautique et la défense n'a baissé que de 46 M€, passant entre 2019 et 2020 de 8,466 Md€ à 8,420 Md€. Les sociétés du secteur aéronautique ont toutefois enregistré des baisses de leur chiffre d'affaires et de leur résultat opérationnel. La Cour des comptes observe la mobilisation de l'État pendant la crise pour préserver ses intérêts stratégiques dans certaines filières critiques : « Au-delà des entreprises à participation publique, l'État semble désormais élargir son action à la sauvegarde d'entreprise stratégiques dont il n'est pas actionnaire et à la garantie d'une autonomie plus grande dans certaines filières stratégiques, dans une logique de souveraineté économique », souligne le rapport.

US Air Force officially buying light-attack planes
By: Aaron Mehta WASHINGTON — The U.S. Air Force is officially putting down its money to buy two different models of light-attack aircraft. The service will purchase two to three aircraft each of the Textron Aviation AT-6 and Sierra Nevada Corporation/Embraer Defense & Security A-29 aircraft. The handful of planes will be used to support “allies and partner capacity, capability and interoperability via training and experimentation,” according to an Air Force announcement. The A-29 Super Tucano contract should be awarded before the end of the year, with the AT-6 Wolverine contract coming in early 2020. The plan to buy a handful of planes was previewed earlier this year by Air Force officials, but the companies will likely breathe a sigh of relief now that the deal is done. The purchase provides a much-needed show of confidence in the project. The two companies have invested internal funds on the Air Force's light-attack experiment over the past two years and remain hopeful the service moves forward with a bigger buy of light-attack aircraft in the future. The missions and basing for the planes will be different. The AT-6s will go to Air Combat Command at Nellis Air Force Base, Nev., for “continued testing and development of operational tactics and standards for exportable, tactical networks that improve interoperability with international partners,” according to the Air Force announcement. The A-29s will go to Air Force Special Operations Command at Hurlburt Field, Fla., and will be used to “develop an instructor pilot program for the Combat Aviation Advisory mission, to meet increased partner nation requests for light attack assistance,” per the release. “Our focus is on how a light attack aircraft can help our allies and partners as they confront violent extremism and conduct operations within their borders,” Air Force Chief of Staff Gen. David Goldfein said in the statement. “Continuing this experiment, using the authorities Congress has provided, gives us the opportunity to put a small number of aircraft through the paces and work with partner nations on ways in which smaller, affordable aircraft like these can support their air forces.” Experiments will continue with a focus on creating a joint architecture and information sharing. The Air Force has said that funding for the initial AT-6 and A-29 buys will come out of the estimated $160 million in unspent funds that Congress appropriated for the effort in previous budgets. Congress has appropriated $200 million in total for the effort since it was announced in late 2016. https://www.defensenews.com/air/2019/10/25/air-force-officially-buying-light-attack-planes/

Air Force awards $38M in contracts for upgrades to airfield in Iceland
Christen McCurdy Sept. 24 (UPI) -- The Air Force has awarded three contracts totaling $38 million to improve the airfield at Naval Air Station Keflavik in Iceland. The Air Force Installation and Mission Support Center's Detachment 4 will direct the construction project with support from Naval Facilities Engineering Command Europe Africa Central, the Air Force said Thursday. The work includes expansion of the airfield's parking aprons, beddown site preparation and an upgrade to the airfield's hazardous cargo pad for the safe unloading and unloading of explosives. "We are upgrading infrastructure at Naval Air Station Keflavik to provide a high level of readiness for U.S. Air Forces in Europe," said Col. David Norton, director of AFCEC's Facility Engineering Directorate. "We have incorporated innovative design and construction techniques to build resilient facilities to ensure the longest lifespan at the overall lowest life cycle cost." The construction projects support the European Deterrence Initiative implemented by U.S. European Command -- an initiative intended to increase the responsiveness of U.S. Air Forces and NATO members and allies in Europe. The EDI includes military exercises and training -- including the annual Dynamic Mongoose exercise, which this year was held off the coast of Iceland -- as well as a rotational presence of U.S. forces in Europe. An April Department of Defense memo said Defense Mark Esper planned to divert funding from overseas military construction projects -- including, critics said, some projects under the auspices of EDI -- to domestic military construction in order to compensate for funding lost to wall construction along the U.S.-Mexico border. https://www.upi.com/Defense-News/2020/09/24/Air-Force-awards-38M-in-contracts-for-upgrades-to-airfield-in-Iceland/6351600969330/
