dronesUS targets a megawatt laser by 2023 and then deployment in drones and satellites for hypersonic and ICBM defense

The US Congress wants the Missile Defense Agency (MDA) to rapidly develop and demonstrate a boost-phase ICBM (and hypersonic weapon) intercept capability as soon as practicable. Space-based laser weapons technology is one of the options. The DARPA High Energy Liquid …

futureUK performing 50 kilowatt Dragonfire combat laser testing

Components arrived in early 2018 for the UK Dragonfire combat laser. QinetiQ will start building the weapon’s laser source in the purpose-built clean room. Over the following months, the laser source will undergo a process of evaluation and adjustment before …

darpaDARPA will use laser power beaming to power solar drones

DARPA will use the Silent Falcon UAS Technologies solar electric, fixed wing, long endurance, long range Unmanned Aircraft System (UAS) for the Stand-off Ubiquitous Power/Energy Replenishment – Power Beaming Demo (SUPER PBD). DARPA will demonstrate the feasibility of recharging the …

futureGeoffrey Landis reviewed interstellar propulsion concepts

Geoffrey Landis works at NASA and has made many contributions to advanced space concepts. In particular to laser pushed sails. The interstellar distance issue was summarized Moon 0.5 million kilometers Mars 50 million kilometers (100X Moon distance) Jupiter 600 million …

energyColliding powerful electron beams and laser pulses to spark the quantum vacuum and create a lot of antimatter

At intensities around 1024 Watts per square centimeter the field should be strong enough to start to break the mutual attraction between some of the electron-positron pairs. This is basically breaking the quantum vacuum of space. New research proposes the …

air forceEngine and electrical improvements will allow the F35 to add combat lasers in the mid-2020s

Pratt and Whitney is proposing improved power, electricity and efficiency for the F35 engine. Increased electrical power and better heat management would allow for combat laser pods to be added to the F35. Electrical and thermal upgrades would be available …

armyUS Army making 100 kilowatt lasers to defend against drones, rockets and mortars

Raytheon Company is developing a 100 kW class laser weapon system preliminary design for integration onboard the Family of Medium Tactical Vehicles. This is a $10 million U.S. Army’s High Energy Laser Tactical Vehicle Demonstration program contract. It is expected …

lasersDo not hold powerful laser weapons next to your face

China has claimed to have developed a combat laser rifle. It would have to have a lot of waste heat. 30-40% efficiency is about the maximum. China claims a mass produced cost of $15,000. If you had a 300-watt laser …

chinaHow does China’s claimed handheld laser rifle compare to the US and to reality?

China has created the ZKZM-500 laser assault rifle is classified as being “non-lethal” but produces an energy beam that cannot be seen by the naked eye but can pass through windows and cause the “instant carbonization” of human skin and …
