Gunbuster 1 could take solar systems.
Gunbuster 3 could literally destroy space time.
That is buster machine 3 flying past planet earth.
"The plan was to launch a massive fleet of warships into the center of the galaxy to lure the space monsters (which were biologically capable of warp travel) away from Earth. BMIII, slowly completing its detonation process, would then warp into the galactic center where the fleet would protect it until it detonated. The fleet would only warp out of the area once the core reached its
explosive compression stage. If everything went as planned, the simultaneous detonation of BMIII and 3000 internally mounted slave units would create a giant black hole that would consume all of the space monsters and their nesting areas within a radius of 10,000 light-years--including a large portion of the galactic core."
