Rolling Airframe Missile (RAM) Block 2

The RAM Block 2 is an upgraded version of the RAM missile aimed at more effectively countering more maneuverable antiship missiles through a four-axis independent control actuator system, increased rocket motor capability, an improved passive radio frequency seeker and upgraded components of the infrared seeker, and advanced kinematics. The Block 2 RAM was delivered to the U.S. Navy in August 2014, with 502 missiles to be acquired from 2015 to 2020.

The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile. It was intended originally and used primarily as a point-defense weapon against anti-ship cruise missiles. As its name indicates, RAM rolls as it flies. The missile must roll during flight because the RF tracking system uses a two-antenna interferometer that can measure phase interference of the electromagnetic wave in one plane only.
