Background

• Problems with the current ammo– Conventional 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 water’s 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.

MEA Advantages

• Up to 20% extended effective range in air– compared to other AP ammunitions of similar caliber from same weapon

• Up to 20% increased effectiveness in armor penetration at range*• Extreme penetrating ammunition – water, armor, materiel, sand, mud• Very low angle target penetration –

• > 2 degrees into water from air• > 15 degrees into armor or curved hard surfaces

• Very low ricochet risk from water surface• Hit targets above or below water line• Projectiles effective through multiple air / water /air (waves)• Projectiles can carry tracer, fuze or HE for secondary destructive effect


MEA Benefits

• Supercavitating MEA rounds are able to enter from the air into the water while maintaining their destructive power

– MEA 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

involved• i.e. passing through waves

– MEA rounds are• Stable in air and water• Spin-stabilized in air and cavity-stabilized in water• Capable 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

Enhanced Effects of the ‘Super’ Cavity:

- 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

projectiles)

• Shooting of inert 324mm MK-46

Other Applications


• 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



• Supercavitating ammunition scalable to all calibers• MEA works in water, from air to water, water to air• Proven, patented technology• Standard weapons• ASW, TCM, UUV & MCM unique solutions• New and enhanced capabilities, new

applications• Small caliber enhanced performance for SOF• Improved stopping power, greater range –
