In Yamato 2199, the output of the wave motion engine can be diverted to form a short-lived spacetime bubble around the exterior of the Yamato. This form of energy shielding is able to effectively dissipate beam weapons and explosive force with high efficacy, but it will drain the output of the wave motion engine rapidly and will typically withstand only half a minute of sustained attacks.

In numerous situations, however, it was shown that the wave motion shields will not fully protect the hull of the Yamato against physical impact such as a ship-to-ship collision, although the damage would be less than it would be without the wave motion shields.
