The Sticky Grenade
The British built 2.5 million “Grenade, Hand, Anti-Tank No. 74“, commonly known as the S.T. grenade or sticky bomb.
The concept is simple, the grenade itself was encased in a very sticky substance, which was then encased in a metal shell. when the pin was pulled, the shell would fall apart. the idea was for a soldier to sneak upon a tank (think WW2) pull the pin, slap it on the tank, then you have 5 seconds to get away from a grenade.
The concept is — interesting. In testing, the British never used them on test tanks or armored vehicles that were dusty or muddy. If they were, the grenade didn’t stick.
Think of tape, it will stick and hold to a nice, clean table, but once you sprinkle sand on it, it will just grab the sand, and become useless. Same thing here.
The grenades, did stick to soldiers uniforms. A story is told of someone using one of these things, and the adhesive got stuck to his leg, and he couldn’t get it off, so a quick thinking friend whipped off the trousers, throwing both the trousers and the grenade away. I doubt that happened. In combat, you keep your trousers cinched tight – with good reason. Ripping them off and tossing them with the grenade ticking, and disposing of them before it detonated — quite a trick — while under fire.
The Soviet Union modified a machine gun (technically, a cannon) originally designed for its TU-22 bomber and installed it in its Almaz spy station. The Almaz was a reconnaissance station launched under the paper-thin guise of a peaceful space station project. Almaz continued to fly throughout the Salyut era, and on Jan 24, 1974, the R-23M Kartech space gun was successfully test fired.
The gun was presumably intended for defense. The 23mm cannon could have obliterated anything ever launched into space, (including the US shuttles) with ease.
They didn’t kill themselves, breach the station, or cause it to unexpectedly de-orbit. Thus the weapon successfully test fired.
They had to rotate the entire 20-ton station to take aim.
Girl’s Best Friend
I had an interesting conversation with an idiot during the Easter holiday, who discussed the capture of diamond smugglers through the use of X-rays. He talked of how Homeland Security demonstrated their techniques in training. Diamonds are radiolucent; their silhouettes will not be detected on an X-ray. But since they didn’t use actual diamonds in testing, SUCCESS! You can’t fix stupid. I don’t know why such people are invited to my son-in-law’s BBQ’s.
