Ship-based Anti-Missile Defense System Sea Sparrow and RAM http://www.youtube.com/watch?v=j-qtoSlBp5w RIM-116 Rolling Airframe Missile The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the American, German, South Korean, Greek, Turkish, Saudi and Egyptian navies. It was intended originally and used primarily as a point-defense weapon against anti-ship cruise missiles. The missile is so-named because it rolls around its longitudinal axis to stabilize its flight path, much like a bullet fired from a rifled barrel. It is the only US Navy Missile to operate in this manner. The Rolling Airframe Missiles, together with the Mk 49 Guided Missile Launching System (GMLS) and support equipment, comprise the RAM Mk 31 Guided Missile Weapon System (GMWS). The Mk-144 Guided Missile Launcher (GML) unit weighs 5,777 kilograms (12,736 lb) and stores 21 missiles. The original weapon cannot employ its own sensors prior to firing so it must be integrated with a ship's combat system, which directs the launcher at targets. On American ships it is integrated with the AN/SWY-2 Ship Defense Surface Missile System (SDSMS) and Ship Self Defense System (SSDS) Mk 1 or Mk 2 based combat systems. SeaRAM, a weapon system model equipped with independent sensors, is undergoing testing. Specifications: Weight 5,777 kg (12,736 lb) (launcher) 73.5 kilograms (162 lb 1 oz) (missile) Length 2.79 m (9 ft 2 in) (missile) Warhead blast fragmentation warhead Warhead weight 11.3 kg (24 lb 15 oz) Wingspan 434 mm (17.1 in) Propellant solid Speed In excess of Mach 2 Guidance system three modes—passive radio frequency/infrared homing, infrared only, or infrared dual mode enabled (radio frequency and infrared homing) Launch platform Mk 144 Guided Missile Launcher (GML) of the Mk 49 Guided Missile Launching System (GMLS) Full Detail http://en.wikipedia.org/wiki/Rolling_Airframe_Missile RIM-162 Evolved SeaSparrow Missile (ESSM) The RIM-162 Evolved SeaSparrow Missile (ESSM) is a development of the RIM-7 Sea Sparrow missile used to protect ships from attacking missiles and aircraft.[6] ESSM is designed to counter supersonic maneuvering anti-ship missiles. ESSM also has the ability to be "quad-packed" in the Mk 41 VLS system, allowing up to four ESSMs to be carried in a single cell. Many countries are using or plan to use the ESSM. The first countries to achieve operational status for ESSM were the United States and Australia. Canada, Germany, Turkey, Greece, Japan, Denmark, the Netherlands, Norway, Spain, and the United Arab Emirates have also integrated or are in the process of integrating the ESSM. Specifications: Weight 620 lb (280 kg) Length 12 ft (3.66 m) Diameter 10 in (254 mm) Warhead 86 lb (39 kg) blast-fragmentation Detonation mechanism Proximity fuze Engine Mk 143 Mod 0 solid fuel rocket Operational range 27nm (50 km) Speed Mach 4+ [4] Guidance system Midcourse datalink Terminal semi-active radar homing Launch platform Mk 41 VLS (RIM-162A/B) Mk 48 VLS (RIM-162C) Mk 29 box launcher (RIM-162D)[5] Full Detail: http://en.wikipedia.org/wiki/Evolved_Sea_Sparrow_Missile Other reads: Anti-Ballistic Missile http://en.wikipedia.org/wiki/Anti-ballistic_missile Aegis Ballistic Missile Defense System http://en.wikipedia.org/wiki/Aegis_Ballistic_Missile_Defense_System Edited by Flipzi, Thu Oct 17, 2013 9:09 am.

Wikipedia photo RIM-174 Standard ERAM The RIM-174 Standard Extended Range Active Missile (ERAM), or Standard Missile 6 (SM-6) is a missile in current production for the United States Navy. It was designed for extended range anti-air warfare (ER-AAW) purposes providing capability against fixed and rotary-wing aircraft, unmanned aerial vehicles, and anti-ship cruise missiles in flight, both over sea and land. The missile uses the airframe of the earlier SM-2ER Block IV (RIM-156A) missile, adding the active radar homing seeker from the AIM-120C AMRAAM in place of the semi-active seeker of the previous design. This will improve the capability of the Standard missile against highly agile targets, and targets beyond the effective range of the launching vessels' target illumination radars. Initial operating capability is planned for 2013. Contents Description The Standard ERAM is a two stage missile with a booster stage and a second stage. It is similar in appearance to the RIM-156A Standard missile. The radar seeker is an enlarged version adapted from the AIM-120C AMRAAM seeker (13.5 inches versus 7 inches). The missile may be employed in a number of modes: inertial guided to target with terminal acquisition using active radar seeker, semi-active radar homing all the way, or an over the horizon shot with cooperative engagement capability. The missile is also capable of terminal ballistic missile defense as a supplement to the SM-3 missile. Unlike other missiles of the Standard family, the ERAM can be periodically tested and certified without removal from the VLS cell. History Raytheon entered a contract in 2004 to develop this missile for the United States Navy, after the cancellation of the SM-2ER Block IVA (RIM-156B) missile. Development started in 2005, followed by testing in 2007. The missile was officially designated RIM-174A in February 2008. Initial low rate production was authorized in 2009. Raytheon received a $93 million contract to begin production of the RIM-174A in September 2009. The first low-rate production missile was delivered in March 2011. SM-6 was approved for full-rate production in May 2013 and the first full-production missile will be delivered in April 2015. As of 2013 the program is scheduled to build 1200 missiles at a total cost of $6,167.8m, at a flyaway cost of $4.3m. On October 03, 2013 Raytheon was awarded a contract for "89 Standard Missile-6 Block I all up rounds, spares, containers and services" by the U.S. Navy. Specifications: Weight 3,300 lbs (1500 kg) Length 21 ft 6 in (6.55 m) Diameter 21 in (0.53 m) max. Warhead blast fragmentation warhead Detonation mechanism radar and contact fuze Engine Two Stage: Solid rocket booster, Solid rocket booster/sustainer Wingspan 61.8 in (1.57 m) Operational range 130 nm (240 km) Flight ceiling > 110,000 ft (33,000 m) Speed Mach 3.5 Guidance system Inertial guidance, active radar homing and semi active radar homing Launch platform surface ship http://en.wikipedia.org/wiki/RIM-174_Standard_ERAM Recommended read: RM-66 Standard Missile http://en.wikipedia.org/wiki/RIM-66_Standard Edited by Flipzi, Thu Oct 17, 2013 8:57 am.

RIM-161 Standard Missile 3 The RIM-161 Standard Missile 3 (SM-3) is a ship-based missile system used by the US Navy to intercept short- to intermediate-range ballistic missiles as a part of Aegis Ballistic Missile Defense System. Although primarily designed as an anti-ballistic missile missile, the SM-3 has also been employed in an anti-satellite capacity against a satellite at the lower end of low Earth orbit. The SM-3 is primarily used and tested by the United States Navy and also operated by the Japan Maritime Self-Defense Force. Motivation and development The SM-3 evolved from the proven SM-2 Block IV design. The SM-3 uses the same booster and dual thrust rocket motor as the Block IV missile for the first and second stages and the same steering control section and midcourse missile guidance for maneuvering in the atmosphere. To support the extended range of an exo-atmospheric intercept, additional missile thrust is provided in a new third stage for the SM-3 missile, containing a dual pulse rocket motor for the early exo-atmospheric phase of flight.[5] The SM-3 was considered for land deployment ("Aegis ashore") initially because of requests from Israel, but Israel then chose to pursue its own system, the Arrow 3. The administration of President Barack Obama however envisaged a European Phased Adaptive Approach (EPAA) and SM-3 was chosen as the main vector of this effort because the competing U.S. THAAD did not have enough range and would have required too many sites in Europe to provide adequate coverage. Compared to the GMD's Ground Based Interceptor however, the SM-3 Block I has about 1/5 to 1/6 of the range. A significant improvement in this respect, the SM-3 Block II variant widens the missile’s diameter from 13.5″ to 21″ making it more suitable against intermediate-range ballistic missiles. The Block IIA missile is largely new sharing only the first-stage motor with the Block I. The Block IIA was "designed to allow for Japan to protect against a North Korean attack with fewer deployed ships" but it also the key element of the EPAA phase 3 deployment in Europe. The Block IIA is being jointly developed by Raytheon and Mitsubishi Heavy Industries; the latter manages "the third-stage rocket motor and nose cone". The U.S. budgeted cost to date is $1.51B for the Block IIA.
