5. Current Threats

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 2001-2007 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 weapons Delivers greatly increased range, improved stopping power, penetration and multi-environment capabilities without modification to existing weaponry

8. Supercavitation • 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 Cavityoutline Core

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) Air Range (supersonic) Caliber Underwater Range 60metres 12.7mm >2,000m >1000m 30metres 7.62mm 5.56mm 800m 15metres 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

12. Target Effectiveness 7.62 DCS (7.62x51)

13. Target Effectiveness 2 shot holes through target plate 7.62mm DCS • Air to Water shot • Std AR-10 weapon fired air to water • 15 degree water entry • 22 feet underwater range • 6mm steel target

14. Target Effectiveness – 7.62mm DCS Shooter Shooter • Sea trials with air to water at low angles. • Target is submerged 6mm steel plate. • Approx. 6-7m water depth. • 7.62x51 DCS ammunitionStd G3 rifle

15. MEA7.62x51 – 7.62mm DCS Specifications • Samples available • In production now • No sabot

16. Target Effectiveness-12.7mm APSX Penetrates >12mm steel at 100 feet underwater 12.7 APSX

17. MEA12.7x99 - 12.7 APSX Specifications • Samples available • In production now • Discarding sabot

18. Possible Targets Semi-submersibles

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

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

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

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

23. Summary • 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!!!!
