The Jet Fighter Laser Cannon
fahrbot-bot sends in a Register piece about DARPA issuing the penultimate contract for what is intended to be a jet-mounted laser cannon. The Reg outdoes itself in a BOTEC involving downsizing to shark scale. "The US military will shortly issue a brace of contracts for 'refrigerator sized' laser blaster cannons. One of the deals will see a full-power ground prototype built which will be the final stage prior to America's first raygun-equipped jet fighter. ... If it scales down far enough, this would seem to put handheld HELL-guns within an order of magnitude of the striking power offered by conventional small-arms. A 9mm pistol bullet has about 750 joules muzzle energy: a 5kg portable HELL-ray weapon would put out this much energy in a blast less than a second long. ... A dolphin can carry a human being weighing up to 100kg along for a ride. A thoroughbred shark in good training can surely match this. Thus, we seem to be looking at practicable head-[laser] output in the 20-kilowatt range."
I always considered the people who religiously adhere to .45 over 9mm, despite its negligible, if any, benefit, to really be compensating for a lack of genitalular fortitude.
Perhaps you should read HEbGb (6544)'s post. You know, the one you're replying to...
Ask your mom to explain the long words.
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
no stopping power.
He is misinformed, likely parroting the same misinformation he was told.
"Stopping power" is a proven myth. It doesn't exist. Period.
