Supercavitation Explained

Supercavitation is the use of cavitation effects to create a bubble of gas or vapor large enough to encompass an object travelling through a liquid, greatly reducing the skin friction drag on the object and enabling high speeds. Current applications are mainly limited to projectiles or fast supercavitating torpedoes.

In water, cavitation occurs when water pressure is lowered below the water’s vapour pressure, forming bubbles of vapour.

A supercavitating object is a high speed submerged object that is designed to initiate a cavitation bubble at the nose which (either naturally or augmented with internally generated gas) extends past the aft end of the object, substantially reducing the skin friction drag that would be present if the sides of the object were in contact with the liquid in which the object is submerged.

Ports and critical infrastructure at sea (oil platforms, windmills, etc.) are vulnerable to attack by divers and unmanned underwater drones. Regular bullets do not travel under water, so to counter the treat, there has typically been a need for dedicated underwater weapon systems.

DSG Technology has developed patented supercavitating ammunition in 5.56, 7.62, and .50 cal. This can be fired from rifles or machine guns. The CAV-X™ round is made in tungsten and the .50 cal round will travel up to 60 meters after it hits the water and will penetrate steel after 100 meters of travel in air and then 30 meters of travel in water. The design allows the round to penetrate the water surface at angles as low as 2 degrees. This effectively eliminates the risk of ricochets and potential collateral damage firing at any targets both over and under the surface in congested environments. An added feature is the ability to engage a target firing through a wave from the bottom of a through.

Being able to stop intruders without harming personnel by shooting through water to destroy the propeller or motorblock of the intruding vessel.
The CAV-X™ .50 cal rounds have the capacity to penetrate an extensive amount of steel after 5-10 meters of travel in water. With CAV-X™ in lower calibers, such as 7.62×51 and 5.56×45 you will also get significant penetration capabilities after several meters of travel through water. 

Bullet flight in water will be visible on a sonar due to the cavity that forms behind the projectile. That will be exceptionally useful in murky waters against any hidden threats.

Applying an effective countermeasure against mines in shallow water is complicated, expensive, and dangerous. Being able to take out mines and other threats in shallow water from a helicopter utilizing already existing weapon platforms will be a safer and more cost-effective solution. These threats are often visible by the naked eye, and if not, using a dipping sonar can help localize the threat and assist with aiming. The successful destruction of the target depends on the thickness of the steel and the depth of the target. CAV-X™ .50 cal rounds will travel over 60 meters after hitting the water.

XMP™ has exceptional accuracy and penetration capabilities at long range, against inclined targets (to 30 degrees), against windscreen barriers, without ricochet and without post-barrier deviation. It offers great performance against several types of intermediate barriers, as well as penetration of multiple layers of steel and near peer L4 body armor. 

Same projectile loaded with a subsonic load becomes SUB-P™. It will also penetrate near peer L4 body armor and AR500 steel.  

Our 7.62×51 XMP™ rounds provide higher force of impact for penetration and destruction of a target than all known existing standard 7.62×51 rounds, namely “twice more” at 500m range and “four times more” at 800m range, also our rounds stay supersonic 50% longer range and has 60-70% reduced wind drift than standard 7.62×51 rounds.
