Hydrolith posted:Phalanx has been in operation for 30 years. Sort of. Later blocks of Phalanx have a surface-enagement mode so they can target things like speedboats. Phalanx is virtually useless against threats like the supersonic ASMs in the above gif because the range is so short that it's only going to get one shot off while the missile passes through the engagement range, and even if it does hit now you have a broken and burning missile body still flying at your ship at supersonic speeds and you're pretty hosed anyway. Goalkeeper is marginally more useful because of its longer range but it's more accurate to say that those missiles were designed to deal with the defense those guns are capable of. They don't even put Phalanx on new ships, the last-ditch close-range anti-missile defense now is RAM, a navalized Sidewinder missile.

ArcMage posted:RAM isn't actually related to the Sidewinder. It's heavily based on it, I was simplifying a bit for a one-paragraph post in the gif thread. From that wiki link: quote:Also known as RIM-116A in US service, the original version called Block 0 whose design is based on that of the AIM-9 Sidewinder air-to-air missile, from which it took its rocket motor, fuze, and warhead.

Thump! posted:They cost just shy of a million each, around $800,000 a pop or so. In the expanse of government military spending, they're a drop in the pool. That's India's Brahmos missile, that's a unique launch profile and it travels at Mach 3. That is an expensive missile, multiply that cost by 3 and you'll be in the ballpark.

FredMSloniker posted:It's a rig NASA used to test space armor plating. The yellow wedge pushes air down the tube, which then constricts, causing the air to push even faster, which sends the pellet out of the tube faster than they could manage with a one-stage air cannon. It's a light-gas gun. A conventional gunpowder charge drives a piston which compresses hydrogen gas into a small chamber that's obstructed by a burst disc. The burst disc is there to prevent expansion of the now-compressed hydrogen until it reaches a given pressure level, at which point the burst disc ruptures and and hydrogen then expands explosively to propel the projectile. It's not air, because the pressure wave traveling down the barrel can't move any faster than the speed of sound in the working fluid. You use hydrogen or helium because the speed of sound in those gases is much higher than in air, so you can achieve much higher muzzle velocities.

C.M. Kruger posted:http://i.imgur.com/4UIUEc7.gifv Actually turning off. That's a TRIGA, if you pull the control rod it heats up, the core expands, and rapidly reaches a configuration where fission can't occur. But while it does that you get a little power spike that you see there in the form of Cerenkov radiation.

Always, at every moment, there will be the thrill of victory, the sensation of trampling on an enemy who is helpless. If you want a picture of the future, imagine this:

Let me know when private space industry has killed as many people as the government programs. NASA alone has a death toll of over 20, counting only active tests and not astronauts in training. China and Russia are both up in the hundreds.

El Mero Mero posted:If you want to see the results of a flight market that's close to an unregulated private market you should just look at Alaska. Whole lot of puddle jumpers and very little oversight means that the state's air safety record is garbage. Saying GA is "close to unregulated" is asinine. It's just as regulated (heavily) as it in in the other 49 states, the difference is that a big chunk of the GA market in the other states isn't flying into and out of extremely remote areas where there aren't even any airstrips, let alone controllers or ASOS broadcasts.
