High-energy #lasers are moving quickly from prototype to deployment for the #USArmy and #USNavy. We’ve helped make that happen.

A brief history of high-energy lasers.

The U.S. military has had electromagnetic spectrum weapons in mind since the 1960s. Throughout the 1980s, industry and military laid the groundwork for figuring out how to reach practical power levels, beam control and adaptive optics. The Department of Defense officially recognized lasers as a plausible future weapon in 1999, marking the beginning of formal research and development.

The company claims its High-Speed Vertical Take-Off and Landing aircraft could blend “the hover capability of a helicopter with the speed, range and survivability features of a fighter aircraft”. Such a system would be capable of “low-downwash hover” and “jet-like cruise speeds over 400kt [740km/h]”, the manufacturer says.

Bell’s conceptual renderings appear to use foldable proprotor technology that the company has disclosed in patent applications. The firm has explored aircraft that can take off vertically using tiltrotors, but then fly forward in cruise mode using wing-borne lift and thrust from jet engines, according to patent applications. Rotor blades would fold back to reduce drag during forward jet-powered flight.

One way such an aircraft might switch between high-speed cruise and VTOL mode is by relying on a “convertible engine”, a jet engine that switches between turboshaft and turbofan modes, according to patent filings. The Lockheed Martin F-35B uses a similar system, called the Rolls-Royce LiftSystem, to facilitate short take offs and vertical landings.

The Pentagon aims to use cutting-edge cloud networks and artificial intelligence systems to anticipate adversaries’ moves before they make them.

The US military’s AI experiments are growing particularly ambitious. The Drive reports that US Northern Command recently completed a string of tests for Global Information Dominance Experiments (GIDE), a combination of AI, cloud computing and sensors that could give the Pentagon the ability to predict events “days in advance,” according to Command leader General Glen VanHerck. It’s not as mystical as it sounds, but it could lead to a major change in military and government operations.

The machine learning-based system observes changes in raw, real-time data that hint at possible trouble. If satellite imagery shows signs that a rival nation’s submarine is preparing to leave port, for instance, the AI could flag that mobilization knowing the vessel will likely leave soon. Military analysts can take hours or even days to comb through this information — GIDE technology could send an alert within “seconds,” VanHerck said.

The most recent dry run, GIDE 3, was the most expansive yet. It saw all 11 US commands and the broader Defense Department use a mix of military and civilian sensors to address scenarios where “contested logistics” (such as communications in the Panama Canal) might pose a problem. The technology involved wasn’t strictly new, the General said, but the military “stitched everything together.”

What do you think?

The idea of using spaceships to travel from one point on the Earth’s surface to another has been around since at least the 1960s, but the cost and complexity of the idea have meant it’s been little more than a pipe dream.

In principle, the approach isn’t that different from the one used by intercontinental ballistic missiles. A rocket is used to blast the payload, be it a nuclear weapon or a passenger spaceship, on a big looping trajectory into space before re-entering the atmosphere on the other side of the planet.

Interesting.

Like other militaries, the Israel Defense Forces for years looked like one organization from the outside, but its services were balkanized in using different networks and data services, an IDF digital leader said in an interview.

“Killer Robots” may seem far fetched, but as @AlexGatopoulos explains, the use of autonomous machines and other military applications of artificial intelligence are a growing reality of modern warfare.

But while science fiction provides military planners with a tantalizing glimpse of future weaponry, from exoskeletons to mind-machine interfaces, the genre is always about more than flashy new gadgets. It’s about anticipating the unforeseen ways in which these technologies could affect humans and society – and this extra context is often overlooked by the officials deciding which technologies to invest in for future conflicts.

Russia has unveiled the Sukhoi Checkmate, a new fifth-generation fighter jet intended to supplement the Su-57 and conquer the international market.

A mockup of the aircraft was presented in a grand ceremony on the opening day of the MAKS airshow in Moscow on July 20, 2021.

“We have been working on the project for just slightly longer than one year. Such a fast development cycle was possible only with the help of advanced computer technologies and virtual testing,” Yuri Slyusar, CEO of United Aircraft Corporation (UAC), said at the event.
