Description


The RIM-162 Evolved Sea Sparrow Missile (ESSM) is a naval surface to air missile of US origin. The ESSM is intended for point defense against both aircraft and incomming missiles. The ESSM is based on the RIM-7P, but only the guidance section remains unaltered. It features slat fins and tail control similar to the Standard missile. This allows for a much larger and wider rocket engine within the same wingspan. Due to the changes the ESSM is very different from the Sea Sparrow and has been given its own RIM-162 designation. Several versions exist, but they show a similar performance.

Variants of the ESSM

RIM-162D
