Barrage cannon
From MediaWiki
When he's not shooting through Decepticon body armor with his ion blaster or slicing off heads with his battle blades, Optimus Prime will use his barrage cannon against his opponents. With a range of up to sixty miles, the laser sighted barrage cannon fires plutonium tipped warheads at a rate of 6 warheads per second, with each warhead carrying the equivalent of 3,000 lbs of TNT.[1]
Remember that, people: Optimus Prime is carrying nukuler nuclear weapons to keep humanity safe from the Decepticons.
