Supercavitating rounds for underwater targets

DSG Technology has 12.7 mm supercavitating ammunition which give them unique capabilities from standard weapons* air to water, water to water and water to air, with exceptional materiel penetration and AP and at low angles. Proven against torpedoes and effective from surface or submerged platforms for mine disposal or against airborne threats, from hidden (submerged) positions. Compatible with standard link or magazines.

Typical effective range: 2200m (air), 60 meter (water).

DSG Technology CEO Jon Andre Garberg likes to think the patented rounds of ammunition his firm has developed can “fly” underwater, rather than “swim.”

The bullets “fly within the bubble of air” created by their own swift movement through water, or “cavitation,” he said.

The trick after that is accuracy and effectiveness, which Garberg said come from the patented tips of the DSG rounds.

The advantage of the DSG rounds over standard ammunition is that they don’t ricochet off the water when firing at a target, potentially putting other ships at risk, Garberg said.

“Spotting a threat is not hard” with the advanced sonars on Navy ships, whether the threat is an enemy diver or an unmanned underwater vehicle (UUV), he said.

The solution to such a threat currently is potential fire from a weapon such as a .30mm cannon, he said.

The 30mm Mk 44 gun is capable of using the Mk 258 Mod 1 armor-piercing fin-stabilized discarding sabot tracer (APFSDS-T) round. The projectile supercavitates in the water. It seems to have a range of about 100 meters in the water.

Is sixty to hundred meter range enough against an explosive torpedo? Seems like the thin hull of current warships would have a very hard time surviving such a close event!

PS Why do I have to give my name & email on every post now? For that matter, why is every comment moderated? What happened to previous comments on various threads, both mine & other's?
