| Description: The
RIM-116 Rolling Airframe Missile (RAM) is a lightweight,
quick-reaction, fire-and-forget missile designed to destroy anti-ship
missiles and asymmetric air and surface threats. The RIM-116 RAM was
developed as a joint program between the U.S. and German governments,
and continues to be cooperatively produced and supported. Currently
there are two RIM-116 configurations: Block 0 (RIM-116A) and Block 1
(RIM-116B). Block 1 is in full rate production. RAM Block 2 has been
approved for System Design and Development phase (April 2007).
Features: The RIM-116 RAM is
designed as an all-weather, high-firepower,
low-cost, self-defense system against anti-ship cruise missiles and
other asymmetric threats. Its original Block 0 design was based on the
infrared seeker of the Stinger missile, and the warhead, rocket motor,
and fuse from the Sidewinder missile. The Block 0 configuration uses
Radio Frequency (RF) for midcourse guidance and transitions to Infrared
(IR) guidance for terminal engagement. There is no shipboard support
required (i.e., no illuminators) after missile launch. The Block 1
incorporates the added capability of autonomous IR-all-the-way
guidance, thus countering advanced anti-ship missiles that do not
employ onboard radar seekers.
The Block 2 provides kinematic improvements to the missile for
countering maneuvering threats and regaining battlespace. It will
feature a Control Section upgrade (4 Canards vs. Current 2) and a
Propulsion Section Upgrade (a larger, composite case rocket motor). It
will also feature cost/producibility improvements. RAM Block 2 Initial
Operating Capability will occur in 2013.
Background: The RIM-116 RAM is
a joint venture between the U.S. and German
governments. It is currently installed, or planned for installation on
100 U.S. Navy and 34 German Navy ships.
