Background
Problems 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 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 AdvantagesUp to
20% extended
effective range in air
compared 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 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 effectCommercial in Confidence © DSG Technology ASSlide5
MEA BenefitsSupercavitating
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 involvedi.e. passing through wavesMEA rounds are
Stable in air and waterSpin-stabilized in air and cavity-stabilized in water
Capable of penetrating steel targets underwater up to 60m for 12.7mmMEA 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 & effectiveFiring rounds from existing shipboard guns offers a highly effective and cost-efficient hard-kill defense
MEA can effectively engage close-in targets

- destructive effect of collapsing cavity even with 200mm near

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.
