RIM-7 Sea Sparrow is a U.S. ship-borne short-range anti-aircraft and anti-missile weapon system, primarily intended for defense against anti-ship missiles. The system was developed in the early 1960s from the AIM-7 Sparrow air-to-air missile as a ...

offered higher performance from a missile that was smaller and lighter, and development of the Sparrow ended in the 1990s.
This left only the Sea Sparrow using the basic platform, and it no longer had to fit on aircraft. So instead of simply using the P and R models as they were, it was decided to dramatically upgrade the weapon as the Evolved SeaSparrow. The ESSM emerged as a completely new weapon, common only in name with the original, although using all of the same support equipment allowing it to be fit to ships already mounting the older models. Compared to the Sea Sparrow, ESSM has a larger, more powerful

Launchers
Mk 29
The original launcher is Mark 29 Guided Missile Launching System Mod. 4 & 5 (Mk 29 GMLS Mod 4 & 5), which is developed from earlier models Mk 29 Mod 1/2/3 for Sea Sparrow. Mk 29 launchers provide on-mount stowage and launching capability for firing up to eight missiles in a self-contained environmentally controlled trainable launcher design.

is the primary launch system for the Evolved SeaSparrow Missile. The Mk 41 is deployed aboard destroyers and frigates, primarily of the United States and allied nations. The ESSM is quadpacked within a Mk 41 cell allowing a significantly increased missile load over
SM-2.
Mk 48
In addition to the Mk 29 GMLS and Mk 41 VLS, the other primary launcher is Mk 48
VLS. The 2-cell module of Mk 48 makes the system very versatile and enables it to be installed on board in spaces that otherwise cannot be utilized. The weight of a 2-cell module of Mk 48 is 660 kg (1,450 lb; including empty canisters), 330 kg (725 lb) for exhaust system, and 360 kg (800 lb) for ship installation interfaces. Each canister of the Mk 48 VLS houses a single RIM-7VL (Vertically Launched) Sea Sparrow cell or two RIM-162 ESSM cells, though, with modification, other missiles can also be launched. There are a total of four models in the Mk 48 family, with Mod 0 & 1 housing either 2 RIM-7VL or 4 RIM-162 cells, Mod 2 housing either 16 RIM-7VL or 32 RIM-162 cells. Mod 0/1/2 are usually grouped into either a 16-cell module for RIM-7VL or a 32-cell module for RIM-162. Mod 3 fits into the

completed a series of live missile firings at the Point Mugu missile launch range off the coast of California that included a total of 11 ESSM missile firings.
The tests included firings against target drones such as the
Northrop BQM-74E Chukkar III and Teledyne Ryan BQM-34S Firebee I, as well as against missile targets such as the Beech AQM-37C and air-launched
Kormoran 1 anti-ship missiles.
Further live firings were performed by the RNLN frigate HNLMS ''De Zeven Provinciën'' in March 2005, again in the Atlantic Ocean approximately west of the Azores.
The tests involved three live-firing events (two of which involved the ESSM) including firing a single
SM-2 Block IIIA at an Iris target drone at long range, a single ESSM at an Iris target drone, and a two-salvo launch (with one salvo comprising two
SM-2 Block IIIAs and the other comprising two ESSMs) against two incoming Iris target drones.

The first "kill" by the RIM-162D from a United States Navy carrier's Mk 29 launcher was achieved during a training exercise by on 7 October 2008.
On 14 May 2013, the ESSM intercepted a high-diving supersonic test target, demonstrating the ability to hit high-G maneuvering, low-velocity air threats, as well as surface targets. No software changes were needed to prove the ESSM's enhanced capability.
On 30 August 2015, during the annual
'Co-operation Afloat Readiness and Training' ('CARAT') exercise, the ESSM was fired from the Royal Thai Navy
