The Firearm Blog points out something that is just wickedly cool:
The DSG Technology ammunition type DR is going to focus on in this article is DSG Multi-Environment Ammunition (MEA) Series Supercavitating Rifle Ammunition (underwater rifle ammo) round, that’s going to be an absolute game-changer for naval and Special Operations waterborne ops of various types, including, but not necessarily limited to, diver protection (defensive) and enemy diver neutralization (offensive) applications, VBSS/MIO (Visit, Board, Search, and Seizure/Maritime Interception Operations) and GOPLATS (Gasoline and Oil Platforms) boarding operations, speedboat interdiction and neutralization, anti-submarine warfare, anti-torpedo operations, and anti-piracy ops.
With DSG Technology’s MEA Supercavitating Rifle Ammo, you can fire at an underwater enemy target from above the water, an above-the-water enemy target from below the surface, or at an underwater target while you are also underwater.
The that the bullet works properly underwater is amazing in of itself, but that it works equally well above and below water is a rather spectacular feat of engineering. Not only does the bullet work above and below water but it’s capable of being fired into the water at very low angles:
The kicker is that DSG MEA supercavitating ammo also has a unique low-angle capability, allowing an operator/shooter to fire the ammo from above the surface into the water at a very low angle of attack, as low as two degrees in choppy water and 7 degrees into glass-smooth water without ricochet. After entering the water, the bullet will continue its true line of flight. There’s no bullet deflection whatsoever, so the operator only need deal with the aforementioned optical refraction of the water.
I’m not going to lie, if this bullet works as advertised it’s going to be freaking amazing. The limited factor of this technology would certainly be the launching platform as few firearms are built to operate reliably underwater (although some are). But as with any advancement in technology other devices will need to play catch up for a while.
With Maritime spring cups your glock should operate underwater.
