It's actually an ammo type, but it could be a weapon hmm...
Also, I'd rename the merc into the Howitzer.
No actual swords, as in "Drive me closer, I want to hit them with my sword!"
I'd make a combat cloak for the squid,
make the lower sideguns of the mobula automatically shoot where the upper sideguns shoot,
give the galleon the ability to kill its main engine in order speed up it's guns and their reloads,
give the junker the ability to soak up all projectiles flying around it for 1/4 of the damage to the armor,
give the pyramidion a 5s -90% horizontal drag +300% engine thrust and -80% impactdamage but kills engines afterwards rocketspeedbutton,
increase the hullhitbox at the spire's bloon whilst reducing all damage the spire takes there and on the lower third of it's hullhitbox by 33%, also give it kind of an autopilot to always face the captain's target,
give the goldfish the ability to strip it's hullarmor to regain 20% permahull and recieve a 5s -70% all drag but can't rebuild hullarmor buff/debuff.
