Reply #93: it cant be steered ? [View All]

The Shkval is considered to be somewhat unrefined because it can travel only along a straight trajectory, but future supercavitating vehicles are being designed to maneuver through the water. Steering is possible through the use of cavity-piercing control surfaces such as fins, and thrust-vectoring systems, which are directional nozzles for jet exhaust. Extreme care must be taken to keep the body inside the cavity during turns, however, because should it stray from the cavity, the force of slamming into the surrounding wall of water would abruptly turn it into "a crushed Coke can," according to Ivan Kirschner, an engineer at Anteon's Engineering Technology Center in Mystic, Conn.

ANTIMINE PROJECTILE. Supercavitating projectiles shot from above the ocean surface must fly stably in both air and water - a difficult engineering task. The RAMICS round (partially visible) was developed by C Tech Defense Corporation.

"Three-dimensional pitch and yaw maneuvers could also be accomplished by moving or rotating the nose cavitator in two planes simultaneously," Kirschner continues, "although such devices would be more complicated." Researchers have also considered using forward-actuated canards.

It can't be steered? OMG how silly is that.

As of 2001

As a result, experts say, the U.S. Navy currently has no supercavitating weapons[br />

Oh, Ok.
