I want meson torpedos, or a high tech long range missile like weapon.
For example, something launched at 10 or 15k from the target, at a 300 or 400 mph speed, which spits in 4 real warheads and 12 decoy ones... Ships would need special tubes to launch that. These tube could be used to launch meson torpedos too (that's self explanatory, high speed, long range, homing, extra powerful missiles, but no decoy warheads in these) !
I want subspace interdictors too, ships that can seal off a node while it's in position, with their modified jump engine (so if there's a danger, it could take some time to reconfigure the engine before it jumps)...
