Description:

The RIM-7 Sparrow is a highly maneuverable air-to-air missile with surface-to-air capability. The missile has a cylindrical body with four wings at mid-body and four tail fins.
The missile is used by the U.S. Navy, the U.S. Army, the U.S.M.C., and NATO members. It can be launched by ships and planes. The U.S. Navy has two launchers to fire the missile: the MK 29 Mod 1 Sea Sparrow launcher (used by foreign navies, too) and the MK 41 VLS.

Aboard AEGIS ships the Navy uses the MK 41 VLS to launch the Sea Sparrow missiles. Because of the vertical launch of the missile a Jet Vane Control unit (JVC) is necessary to cancle the missile's initial upward velocity and control transition to the initial intercept path. After the seeker is pointing toward a target, the JVC is jettisoned. A quick-reaction, 360-degree defense and eliminating trainable firing restriction and time consuming slew requirement is provided by vertical launch.
To steer the missile uses its wings while the Evolved Sea Sparrow Missile (ESSM) uses skid-to-turn steering (tail control).

The Launchers:

The NATO MK 29 Mod 1 launcher (left and right image below) can be found aboard many US NAVY ships such as Aircraft Carriers and Amphibious Assault Ships and many foreign NATO ships. The MK 41 VLS (center image below) can be found aboard TICONDEROGA-class cruisers, the ARLEIGH BURKE-class and the SPRUANCE-class destroyers. Only AEGIS ships (the TICONDEROGA-class and the ARLEIGH BURKE-class) use the VLS to launch Sea Sparrow missiles.


The MK-25 and Mk-29 Launchers:


Mk 29 NATO Sea Sparrow launcher aboard the German frigate BREMEN F-207In the 1960th the Navy created a new anti-air system. This system was named BPDMS (Basic Point Defense Missile System). It consisted of the Mk 25 launcher and of adapted Sea Sparrow missiles. The design of this launcher was similar to the ASROC missile launcher.

Shortly after introduction of the BPDMS many ships without Standard-Systems got the new system because the whole installation was not very expensive. A disadvantage was the short range of just 18 kilometers.

In 1974 a new launcher was introduced: The Mk 29 Sea Sparrow launcher. It had a lower weight and did not use the RIM-7G but the improved RIM-7H missiles. Today, this launcher is also used by many NATO navies. This system is also known as IPDMS (Improved Point Defense Missile System).

Today, there is no US Navy ship left equipped with the MK-25 launcher.
