Supercavitating Ammunition
Commercial in Confidence © DSG Technology AS
Most Effective Solution for Self Defense
Multi 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 weaponry
Underwater, Water-to-Air, Air-to-Underwater, Air-to-Air

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 costefficient hard-kill defense
•
MEA can effectively engage close-in targets

Reference Points
•
NATO NIAG Study 159 ‘Hardkill Torpedo Countermeasures’, recommended MEA
supercavitating gunfire as the best complementary hardkill solution to AntiTorpedo 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.
