1 Equipping Helicopters/Boats with the Supercavitating Multi Environment Ammo (MEA)™

2 The MH-60J – All weather, medium-range helicopter (specialized for search and recovery) similar to the Navy MH-60R and MH-60S Seahawk – There are 42 total MH-60Js in the Coast Guard air fleet, with 35 in operational use. Armament – Single 7.62mm M240J machine gun – 7.62mm shoulder-fired precision weapon The MH-60J

3 The H-65 Helicopter The H-65 helicopter – All-weather and night-time operations – FLIR, a heads-up display and other avionics upgrades are being installed aboard the H-65 for law- enforcement operations. Armament – Single 7.62mm M240B/H machine gun – 7.62mm shoulder-fired precision weapon –.50-caliber shoulder-fired precision weapon

4 Boats 33-foot Law Enforcement Special Purpose Craft (SPC-LE) 25-Foot Defender Class Boat (RB- HS/RB-S) 41' UTB Armament: 7.62mm M240 machine gun

5 Current Threats

6 Drug-Running Mini-Subs and Semi Submersibles A drug smuggling semi- submersible captured in Colombia last summer. 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."

7 M.E.A. - Multi Environment Ammunition ™ 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 The Most Effective Solution for Self Defence

8 In water at speed >100m/s (328ft/s; 109yd/s) the core forms a cavity that is optimally designed to exceed the size of the projectile Water resistance in the cavity acts solely on the leading edge Stabilization is achieved through contact with the cavity by rear of the projectile The 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 penetration Supercavitation Core Cavity outline

9 Benefits OF MEA 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/air entries are involved (i.e. passing through waves) – MEA rounds: - Are stable in air and water - Are spin-stabilized in air, and cavity-stabilized in water - Are 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 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

10 MEA Performance (Effective Range) Underwater Range 12.7mm 60metres 7.62mm 30metres 5.56mm 15metres Caliber Air Range (supersonic) >2,000m >1000m 800m Note: Just requires changing to MEA ammunition!!

11 Target Effectiveness-Underwater 5.56mm DCS 5 shots in target plate Water to water shots Std HK 416 weapon 38 feet underwater range 3mm aluminium target

18 Possible Targets Semi-submersibles

19 7.62 = 20m under water Cal.50 = 60m underwater MEA can destroy Speed Boats using.50 cal or M240 - above and below water line Passing through waves 5.56 = 10m under water Will enter water without ricocheting at low angles through multiple air/water/air interfaces (i.e. passing through waves)

20 7.62 = 20m unserwater Cal.50 = 60m 20mm = 150m MEA can destroy Mini Subs Using the 12.7mm APSX or 7.62 mm DCS Rounds.50 cal When underwater targets are identified, pilots can engage threats JUST BY CHANGING THE AMMO to MEA LOW ANGLE OF ENTRY M240

21 Anti-Mine Application 7.62 = 20m Cal.50 = 60m20mm = 150m under water MEA can destroy mines using the 12.7mm APSX 20mm or 30mm guns NOT required with the MEA Detecting Mines at Sea Using Blue/Green Lasers

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

23 5.56mm, 300BLK and 7.62mm DCS MEA in production 12.7mm APSX MEA available now. In production. MEA independently evaluated by NIAG study as most effective hardkill solution for ship defence Air/Water and Material Penetration performance fill current naval capability gaps Enhances capabilities of standard weapons on helicopters, surface vessels, patrol boats Effective ammo for Surface swarming threats Effective ammo for Semi-submersible and submerged threats –defensible from helicopters and boats. Mine counter measures, using 12.7mm to depths of 40-60metres Exceptional material penetration: including, ground, soil, mud, sand, armour – and water Extended capabilities for any weapon used or carried over water, on any platform Just change the ammo!!!!
