XM70E2



"As the 50s came to a close while the 60s took its place, the XM70 would be the thing that the United States Marine Corps would do their best to ease fears against communism. But I know it's that same old thing that more and more Americans were still thinking that communism is an insidious thing, but that's what everybody's been debating for. Right now, we'll use this to protect Shantae as well."

--Su Ji-Hoon, The Insidious Plan

The XM70 was a rocket launcher developed for the U.S. Marine Corps from 1959 to 1963 at Rock Island Arsenal, Illinois Research and Development Division. Seven prototypes were built and tested at Rock Island Arsenal and Aberdeen Proving Ground, Maryland. The Army intended to develop a self-propelled variant designated the XM71 as the core weapon system matured.

The XM70 has an unusual layout for a rocket launcher, borrowing most of its characteristics from towed howitzers. It used a closed breach and a hydraulic recoil mechanism rather than allowing rocket exhaust to exit the rear of the device, which allowed the crew to remain nearby to individually aim each rocket and to rapidly reload. It also had long trail arms and a base plate to pivot the system in common with conventional towed artillery.

The XM70 employed a unique revolver-like rotary magazine to fire rockets through a single launch tube in succession, rather than individual tubes for each rocket with the intent of improving accuracy while maintaining low overall weight and mobility.

Most multiple launch rocket systems use individual smoothbore tubes roughly the same length of each fin-stabilized rocket bundled in parallel for firing in rapid barrages. The XM70's single shared long barrel has grooves indicative of rifling to spin the rocket to gyro stabilize it in flight to provide additional accuracy.
