Subspace Reactor Cannon
The most powerful ship-mounted weapon in existence and probably the most destructive thing in the universe built by the hands of thinking creatures, a subspace reactor cannon uses the largest paccel rings available to create an ongoing subspace tear “parented to” a slow-moving (275 m/s, 902 fps) projectile. As the projectile travels through space, the ongoing subspace reaction grows more and more violent and begins unpredictably tearing holes to subspace all around the slug, eventually forming a constantly-replenishing parabolic envelope of subspace around the slug some 9m (29 ft) in diameter. In addition, random pockets of subspace flicker open and closed constantly with a spread of decreasing density in a cloud up to 3600m (2.2 miles) from the warhead. Anything in the path of the subspace envelope surrounding the slug is erased from realspace, and anything within the two-mile cloud of tears is shredded as parts of it get removed from realspace chaotically, leaving behind distinctive “Swiss cheese” debris.
A direct hit from a subspace reactor cannon should obliterate any ship in space except one of comparable size to the Ring Battleship that produced the blast in the first place, which would merely be instantly crippled. Five ring battleships firing their subspace reactor cannons continuously could destroy a Terra-sized planet in about twelve minutes.
