We can watch some soldiers fired to water or underwater to hit enemies in movie or video.\u00a0 But this is an illusion. Existing bullet cannot penetrate and enter water even.\r\n\r\nBut, this can become a reality if one technology is applied. <strong>&#8220;Super-cavitation&#8221;<\/strong> Super-cavitation is a phenomenon whereby a large vapor bubble surrounds much of a moving object, such as a high-speed submerged vehicle. And an cavitation tunnel must be formed in which the warhead can travel overcoming the density of the fluid in order to attack a target underwater. Two cavitation tech. which are ventilated super-cavitation and natural super-cavitation are being investigated in academia and industry. Ventilated super-cavitation is a technology that forcibly forms a tunnel through which the projectile passes by blowing air toward the front of the projectile. This way is already applied to large weapon system compared to bullet such as torpedo. However, the small caliber warhead has not space to store gas or air. Thus, <strong>Natural super-cavitation is only answer which can be applied to small caliber for hit a target underwater.<\/strong>\r\n\r\nDureTek has secured the core technologies for creating a natural super-cavitation tunnel so that it can attack a target in the water by simply replacing the warhead from the existing ammunition without changing barrel. It called DrMEP(DureTek Multi Environment Projectile). These technologies are convergence with HPP tech. Thus, it is not only underwater. DrMEP can use battle environments both ground and underwater.\r\n<ul>\r\n \t<li>Tip for natural super-cavitation<\/li>\r\n \t<li>Stiffness of core material<\/li>\r\n \t<li>Flight stability from HPP<\/li>\r\n<\/ul>\r\n<strong>Three cores combine, You can attack and defense enemy not only underwater but also ground.<\/strong>\r\n<h3>Experiment Results of DrMEP<\/h3>\r\nWe\u2019ve tried to test various situations to verify the ammunition works as advertised. Now with the help of testing facilities in South Korea, we\u2019ve seen it happen over and over again enough to say that the test data is trustworthy. We conducted some tests in facilities and for accuracy in the tests, the 5.56mm caliber fired using a certified 10.5&#8243; barrel and 7.62mm caliber fired using a certified 13&#8243; barrel.\r\n\r\nIn several tests, it proves that the DrMEP bullet can fly straight into the air and keep going straight into the water. Also, it proves that the DrMEP can not only fly straight into the air but also it could keep flying straight after it went through the water by penetrating two water tanks.\r\n\r\n<figure id=\"attachment_634\" aria-describedby=\"caption-attachment-634\" style=\"width: 523px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/duretek.com\/wordpress\/wp-content\/uploads\/2023\/01\/\ucd08\uacf5\ub3d9-\uc2e4\ud5d8-\uc7a5\uba74.png\" alt=\"\" width=\"523\" height=\"224\" \/><figcaption id=\"caption-attachment-634\" class=\"wp-caption-text\"><strong>Test DrMEP at two water tank air-water-air shot<\/strong><\/figcaption><\/figure>\r\n\r\nHere is table of comparison results between DrMEP and existing warhead.

Typically underwater bullets are used for operations like a soldier needs to shoot from a helicopter into the water. In order to neutralize naval mines, the bullet needs to be precious. However, the traditional water bullet couldn\u2019t hit naval mines with one shot. Maybe multiple shots might increase the chance to hit the target but even multiple shots didn\u2019t ensure hitting the target.\r\n\r\n<strong>Now with Duretek\u2019s DrMEP, any soldier can use an underwater bullet like a sniper bullet.<\/strong>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-ceb83fa elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"ceb83fa\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-a2260df\" data-id=\"a2260df\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-8ad45ce elementor-widget elementor-widget-text-editor\" data-id=\"8ad45ce\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<h4>Natural Super-cavitation projectile shot test<\/h4><p>DrMEP which was fired at 100m in front of pool generated <strong>5m cavitation tunnel<\/strong> in pool.
