Supercavitating Ammunition

Commercial in Confidence DSG Technology AS1Most Effective Solution for Self DefenseMulti Environment Ammunition (M.E.A.)

Enhancing capabilities of 7.62mm, 12.7mm, 20mm, 25mm, and 30mm applications with standard weapons

Delivers greatly increased range, improved stopping power, penetration and multi-environment capabilities without modification to existing weaponryUnderwater, Water-to-Air, Air-to-Underwater, Air-to-AirCommercial in Confidence DSG Technology AS

BackgroundProblems with the current ammoConventional rounds lose significant velocity when fired from the air through or into water. Trying to defend against water-borne attacks , such as swarming boats, where rounds have to penetrate a water barrier, such as a wave, to hit the target is, therefore, futile. Conventional rounds in route to a target, instead of entering the water, may ricochet off the waters surface and lose velocity, proving futile against a swarm attack.Swarming surface boat hard-kill is one of the applications of supercavitating rounds. While various forms of supercavitating ammunition have existed for many years, they typically require very steep angles of incidence (>60 degrees) in order to enter the water from air, making such ammunition ineffective for shipboard use to defend against a swarm attack.CavityProjectileWaterCommercial in Confidence DSG Technology AS

MEA AdvantagesUp to 20% extended effective range in aircompared to other AP ammunitions of similar caliber from same weaponUp to 20% increased effectiveness in armor penetration at range*Extreme penetrating ammunition water, armor, materiel, sand, mudVery low angle target penetration > 2 degrees into water from air> 15 degrees into armor or curved hard surfacesVery low ricochet risk from water surfaceHit targets above or below water lineProjectiles effective through multiple air / water /air (waves)Projectiles can carry tracer, fuze or HE for secondary destructive effect

MEA BenefitsSupercavitating MEA rounds are able to enter from the air into the water while maintaining their destructive powerMEA rounds enter or leave water at very low angles (> 2 degrees)MEA rounds enter the water without danger of ricocheting, even when multiple air/water/ entries are involvedi.e. passing through wavesMEA rounds areStable in air and waterSpin-stabilized in air and cavity-stabilized in waterCapable of penetrating steel targets underwater up to 60m for 12.7mm

MEA bullets can penetrate water, sand, and mud (wet or dry)Bullet profile enables highly effective penetration of difficult materials including dry or wet sand and mud. Bullet remains intact & effective

Firing rounds from existing shipboard guns offers a highly effective and cost-efficient hard-kill defense

MEA can effectively engage close-in targets

- near misses are still effective- destructive effect of collapsing cavity even with 200mm near misses

- cavity persists in water (more than 30meters for 30mm)- increases chances of affecting target

- hydro-static shock extends damage-radius - more than 1 meter radius in surrounding water volume

NATO NIAG Study 159 Hardkill Torpedo Countermeasures, recommended MEA supercavitating gunfire as the best complementary hardkill solution to Anti-Torpedo Torpedo for ship defense. (Reported June 2012)

A European navy has successfully trialled MEA 12.7 APSX against torpedo with fatal damage to real (static) torpedo, fired from air to water with single shots, through 25 metres water at 15 degrees angle of incidence. (Scaled trial: actual application will use Medium Calibre).

DSGT has proven MEA effectiveness against real torpedo at 125 metres underwater range, using 30mm MEA, penetrating at very low angles.Reference Points
