Evolved Seasparrow Missile (ESSM) (RIM 162D)

ESSM is part of a 10-nation international cooperative development program between the U.S., NATO partner nations and Australia and is a kinematic upgrade to the RIM-7P SEASPARROW Missile that leverages U.S. guidance technology. ESSM is a medium-range, semi-active homing missile that makes flight corrections via radar and midcourse data uplinks. The missile provides reliable ship self-defense capability against agile, high-speed, low-altitude anti-ship cruise missiles (ASCMs), low velocity air threats (LVATs), such as helicopters and high-speed, maneuverable surface threats. ESSM is integrated with a variety of U.S. and international launchers and combat systems across the Consortium navies and several Foreign Military Sales customer nations.

ESSM has 10-inch diameter control and rocket motor sections that tapper to an 8-inch diameter guidance section that utilizes a radome-protected antenna for semi-active homing and an IM compliant warhead section. The high-thrust, solid-propellant rocket motor provides high thrust for maneuverability with tail control via a Thrust Vector Controller (TVC).

ESSMs effective tracking performance and agile kinematics result from S- and X-band midcourse uplinks, high average velocity and tail control, increased firepower with the MK 25 quad pack canister used for MK 41 Vertical Launch System (VLS)-equipped ships and greater lethality with an improved warhead designed for defeating hardened ASCMs.
ESSM is a cooperative effort among 10 of 12 NATO SEASPARROW Consortium nations governed by a Production Memorandum of Understanding (MOU) and multinational work-share arrangement. In addition to the United States, ESSM member nations include Australia, Canada, Denmark, Germany, Greece, The Netherlands, Norway, Spain and Turkey.

The first production ESSM was delivered in late 2002 to the U.S. Navy by Raytheon Missile Systems (RMS) and has been in full operational use in the U.S. since 2004. ESSM is fired from the following U.S., NATO and other launcher systems: MK 29 trainable launcher, MK 41 VLS, MK 57 VLS, MK 48 Guided Missile VLS and the MK 56 Dual Pack ESSM Launching System. ESSM also interfaces with a variety of combat systems, including the Aegis Weapon System, MK 57 NATO SEASPARROW Missile System (NSSMS) / Ship Self-Defense, Ship Self-Defense System (SSDS), Total Ship Computing Environment, ANZAC, Dutch Configuration, FLEXFIRE and APAR combat systems.
