So you want loads of iATM9 launchers with good staying power.
the Osteon with its 4 launchers and plenty reinforced chassis clad in ferro lamellor is certainly the goto idea.
What if I told you could get an entire star of mechs with the same movement profile quad launchers on each giving you 5 times more missile output and instead of being limited to 13 tones of ammo you have 35. Prototype AES is used for accuracy instead of the expensive nova CEWS (equipping the star with those costs as much as another mech). And survivability wise, the redundancy clad in a combined 45 tonnes of ferro fibrous armor gives the enemy a bit to work through.
Then go for these stripped down, low tonnage standard engine equipped, chopped arm, non omni, Septicemias
