DARPA recently awarded contracts to five companies to develop algorithms enabling mixed teams of manned and unmanned combat aircraft to conduct aerial dogfighting autonomously.

Boeing, EpiSci, Georgia Tech Research Institute, Heron Systems, and physicsAI were chosen to develop air combat maneuvering algorithms for individual and team tactical behaviors under Technical Area (TA) 1 of DARPA’s Air Combat Evolution (ACE) program. Each team is tasked with developing artificial intelligence agents that expand one-on-one engagements to two-on-one and two-on-two within-visual-range aerial battles. The companies’ algorithms will be tested in each of three program phases: modeling and simulation, sub-scale unmanned aircraft, and full-scale combat representative aircraft scheduled in 2023.

“The TA1 performers include a large defense contractor, a university research institute, and boutique AI firms, who will build upon the first-gen autonomous dogfighting algorithms demonstrated in the AlphaDogfight Trials this past August,” said Air Force Col. Dan “Animal” Javorsek, program manager in DARPA’s Strategic Technology Office. “We will be evaluating how well each performer is able to advance their algorithms to handle individual and team tactical aircraft behaviors, in addition to how well they are able to scale the capability from a local within-visual-range environment to the broader, more complex battlespace.”

The U.S. Air Force envisions placing laser weapon systems on fighter jets by the mid-2020s. The service is banking on a defense contractor’s SHiELD laser system, a pod-mounted laser that will protect fighters from incoming missiles.

In arguing against nuclear war, Dr. Tsipis said he came « to believe that reason must prevail. »

A curious boy who gazed at the stars from his mountainside Greek village and wondered how the universe came to be, Kosta Tsipis was only 11 when news arrived that the first atomic weapon had been dropped on Hiroshima, Japan.

“After the bomb went off, I sent away for a book because I wanted to understand it,” he told the Globe in 1987.

WASHINGTON — SpaceX was awarded a $29.6 million contract under the National Security Space Launch Phase 2 contract that allows the U.S. Space Force to monitor and study data from the company’s commercial and civil space missions.

The one-year contract “provides early integration studies and fleet surveillance for non-national security space missions,” said the Space Force contract announcement Nov. 9.

Fleet surveillance includes access to proprietary “tools, systems, processes and launch site activities developed by the launch service provider for non-national security space missions,” said the Space Force.

SAN FRANCISCO – L3Harris Technologies will help the U.S. Defense Department extract information and insight from satellite and airborne imagery under a three-year U.S. Army Research Laboratory contract.

L3Harris will develop and demonstrate an artificial intelligence-machine learning interface for Defense Department applications under the multimillion-dollar contract announced Oct. 26.

“L3Harris will assist the Department of Defense with the integration of artificial intelligence and machine learning capabilities and technologies,” Stacey Casella, general manager for L3Harris’ Geospatial Processing and Analytics business, told SpaceNews. L3Harris will help the Defense Department embed artificial intelligence and machine learning in its workflows “to ultimately accelerate our ability to extract usable intelligence from the pretty expansive set of remotely sensed data that we have available today from spaceborne and airborne assets,” she added.

Four decades of supersonic-combustion ramjet propulsion research culminated in a successful flight of the X-43A hypersonic technology demonstrator in March 2004, the first time a scramjet-powered aircraft had flown freely. After being launched by Dryden’s venerable B-52B mothership off the coast of Southern California, a modified first-stage Pegasus booster rocketed the X-43A to 95,000 feet before the X-43A separated and flew under its own scramjet power at an airspeed of Mach 6.8, or about 5,000 mph, for about 11 seconds. On Nov. 16, another identical scramjet-powered X-43A did it again, this time reaching hypersonic speeds above Mach 9.6, or about 6,800 mph, in the final flight of the X-43A project. Both flights set world airspeed records for an aircraft powered by an air-breathing engine, and proved that scramjet propulsion is a viable technology for powering future space-access vehicles and hypersonic aircraft.

The head of the UK military, General Sir Nick Carter, believes robots could make up a quarter of the army by the 2030s.

Imagine this scenario: You’re deployed to some godforsaken hellhole downrange, in desperate need of additional ammo and chow. You call your superior officer for a very special airdrop: with approval from the U.S. Transportation Command, your cargo is launched into low earth orbit in a rocket-assisted payload. Within an hour, voila — fresh 5.56mm rounds and some delicious pizza MRE, ready to refresh your arsenal and renew your spirit.

The idea of space-borne resupply pods may seem like something out of science-fiction but it could someday be a reality for troops downrange, according to Army officials.
