2 MK-44 Mod 4 Rolling Airframe Missile (RAM) Guided Missile Round Pack (GMRP)
All-Up-Rounds. Its a Navy Anti Ship Missle Pack. there was a story on Defense Tech about the Navy building a bunch for Germany. Read more: http://defensetech.org/#ixzz2PEMnifyd
This is a real thing. A reloadable missle pack system with (21) Anti-Target missles. Ships, planes, helicopters, etc.
Turn that thing on its side and mount it on a big stompy robot, and I'm looking at a REAL Robotech Macross Phalanx arm.
Now all we have to do is develop full anthropomorphic mobile robots weighing 200 tons. Piece of cake.
That and make all of the missle heads flat for optimum performance and range.
