weighs 318 tons runs at 296 km/s ± planet pull I restricted myself in width and using only normal quality I thought the single iron casting foundry would restrict ammo production so I researched to physical projectile damage 16 and stronger explosives 14. With the belts fully stacked it can easily run continuously for over an hour. If it stops at planets at all or goes between the inner planets I don't have to worry about ammo.
