1 Equipping Helicopters/Boats with the Supercavitating Multi Environment Ammo (MEA)™
2 The MH-60JThe MH-60JAll weather, medium-range helicopter (specialized for search and recovery) similar to the Navy MH-60R and MH-60S SeahawkThere are 42 total MH-60Js in the Coast Guard air fleet, with 35 in operational use.ArmamentSingle 7.62mm M240J machine gun7.62mm shoulder-fired precision weapon
3 The H-65 Helicopter The H-65 helicopter All-weather and night-time operationsFLIR, a heads-up display and other avionics upgrades are being installed aboard the H-65 for law-enforcement operations.ArmamentSingle 7.62mm M240B/H machine gun7.62mm shoulder-fired precision weapon.50-caliber shoulder-fired precision weapon

6 Drug-Running Mini-Subs and Semi Submersibles Latin American drug smugglers are stepping up their use of small, hand-made mini-subs in order to avoid U.S. military patrols in the eastern Pacific.Between alone, the US Coast Guard detected 23 mini-subs. This number has "ballooned."A drug smuggling semi-submersible captured in Colombia last summer.
7 The Most Effective Solution for Self Defence M.E.A. - Multi Environment Ammunition™Enhancing capabilities of 7.62mm, 12.7mm, 20mm, 25mm and 30mm applications, with standard weaponsDelivers greatly increased range, improved stopping power, penetration and multi-environment capabilities without modification to existing weaponry
8 SupercavitationIn water at speed >100m/s (328ft/s; 109yd/s) the core forms a cavity that is optimally designed to exceed the size of the projectileWater resistance in the cavity acts solely on the leading edgeStabilization is achieved through contact with the cavity by rear of the projectileThe cavity collapses when speed of the projectile reduces to approx 100m/s (≈328ft/s; 109yd/s)DSGT’s patented supercavitating projectile design enables air/water capabilities, but also gives reduced drag in air, with extended range, increased stopping power, and material penetrationCoreCavity outline
9 Benefits OF MEASupercavitating 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/air entries are involved (i.e. passing through waves)MEA rounds:Are stable in air and waterAre spin-stabilized in air, and cavity-stabilized in waterAre 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 materialsincluding dry or wet sand or mud. Bullet remains intact & effective.Firing such rounds from existing shipboard guns offers a highly effective and cost-efficient hard-kill defense.MEA can effectively engage close-in targets

22 Additional Supercavitation Benefits Enhanced Effect of the ‘super’ Cavity:Near misses are still effective- destructive effect of collapsing cavity even with 300mm near missesCavity persists in water (more than 30metres for 30mm)- increases chances of affecting target
