Cool Underwater Robots With Guns? It's Coming—Sooner Than You Think

Underwater Robots With Guns? It's Coming—Sooner Than You Think | The National Interest 1-1-2020

FROM THE ARTICLE
Effective range of this ammo is around fifteen meters underwater, and over 500 meters in air for the 5.56 round. The larger calibers also have extended effective ranges. Another advantage of supercavitation is the retention of accuracy when shooting in and out of water. While normally significant accuracy and velocity reductions are present when shooting into water, with supercavitating ammo velocity and accuracy are retained. This allows for frogmen to shoot sentries from underwater if their rifles are loaded with MEA ammunition.
