Longbow or grauwolf advanced ammunition

[Estutes]

Coming from the idea of the real life m551 that could fire both conventional (primer+cartridge+warhead) and ATGM missiles (rocket propelled warheads) in conjunction with the idea that having the Horizon a dedicated torpedo launching bay being too OP... I've come up with the idea of a special kind of modified cartridge for the longbow that instead of being purely explosive, is an advanced cartridge manufactured or bought by operations that contains a nozzle+engine+fuel+computer that would allow for the horizon shooting its longbow without lining up shots. This would allow for the SCCV Horizon to fire while fleeing a what would be a rocket propelled warhead that seeks its target.

This idea could also be applied to the grauwolf as a "guided" cheaper to produce alternative although that might break balance, or perhaps It's a better choice. You decide!
