Video of the Test Firing the Sukhoi PAK-FA/T-50 Cannon

Don't make too much of this.

Mainly, yes, its a test. It does look impressive.

However, the test stand/faux nose shouldn't be mocked. it's doing as it should and who cares if its rusty.

The one thing we might be able to infer is how many rounds the Pak-fa can carry based on the box shown (underfilled for the test).

That might be a stretch though.

Note: its not a railgun or any other type of em gun.
