Raytheon has received a $10.4 million contract modification
for Navy Close-In Weapon System
(CIWS) SeaRAM upgrades. The company received a $159 million production contract
for CIWS systems, with the contract also covering support equipment for the Rolling Airframe Missile
system. The SeaRAM improves the CIWS's Phalanx Block 1B radar system with an eleven-missile RAM launcher to expand the system's defensive capabilities.
The radar-guided, rapid-firing MK 15 Phalanx Close-In Weapons System (CIWS, pron. “see-whiz”) can fire between 3,000-4,500 20mm cannon rounds per minute, either autonomously or under manual command, as a last-ditch defense against incoming missiles and other targets. Phalanx uses closed-loop spotting with advanced radar and computer technology to locate, identify and direct a stream of armor piercing projectiles toward the target. These capabilities have made the Phalanx CIWS a critical bolt-on sub-system for naval vessels around the world, and led to the C-RAM/Centurion, a land-based system designed to defend against incoming artillery and mortars.
This DID Spotlight article offers updated, in-depth coverage that describes ongoing deployment and research projects within the Phalanx family of weapons, the new land-based system’s new technologies and roles, and international contracts from FY 2005 onward. As of Feb 28/07, more than 895 Phalanx systems had been built and deployed in the navies of 22 nations.

Thailand has been cleared
by the State Department to buy RIM-162 Evolved Sea Sparrow Missiles
. The potential deal is estimated to value $26.9 million, including canisters and other auxiliary equipment. The Royal Thai Navy became the thirteenth ESSM customer in January 2013
, with the country signing a letter of acceptance with prime contractor Raytheon following a DSCA request in August 2012.
The RIM-162 Evolved Sea Sparrow Missile (ESSM) is used to protect ships from attacking missiles and aircraft, and is designed to counter supersonic maneuvering anti-ship missiles. Compared to the RIM-7 Sea Sparrow, ESSM is effectively a new missile with a larger, more powerful rocket motor for increased range, a different aerodynamic layout for improved agility, and the latest missile guidance technology. Testing has even shown the ESSM to be effective against fast surface craft, an option that greatly expands the missile’s utility. As a further bonus, the RIM-162 ESSM has the ability to be “quad-packed” in the Mk 41 vertical launching system, allowing 4 missiles to be carried per launch cell instead of loading one larger SM-2 Standard missile or similar equipment.
This is DID’s FOCUS article for the program, containing details about the RIM-162 Evolved Sea Sparrow missile family, and contracts placed under this program since 1999. The Sea Sparrow was widely used aboard NATO warships, so it isn’t surprising that the ESSM is an international program. The NATO Sea Sparrow Consortium includes Belgium, Canada, Denmark, Germany, Greece, The Netherlands, Norway, Portugal, Spain, Turkey, and the USA – as well as non-NATO Australia. Foreign Military Sales ESSM customers outside this consortium include Japan, Thailand, and the United Arab Emirates.

A Standard Missile-3 Block IA interceptor, fired from an Arleigh Burke-class
destroyer, has successfully intercepted
a short-range ballistic missile. The target missile was launched from the UK's Hebrides Range, off the northwest coast of Scotland, with the test also seeing two anti-ship missiles fired simultaneously. The ballistic missile was intercepted in space by the SM-3 fired from USS Ross (DDG-71), with USS The Sullivans (DDG-68) downing the anti-ship missile using SM-2 missiles
. The Sullivans saw a SM-2 Block IIIA explode soon after launch in July
, with this test the first time a ballistic missile has been intercepted in the European theater.

Variants of the SM-2 Standard missile are the USA’s primary fleet defense anti-air weapon, and serve with 13 navies worldwide. The most common variant is the RIM-66K-L/ SM-2 Standard Block IIIB, which entered service in 1998. The Standard family extends far beyond the SM-2 missile, however; several nations still use the SM-1, the SM-3 is rising to international prominence as a missile defense weapon, and the SM-6 program is on track to supplement the SM-2. These missiles are designed to be paired with the AEGIS radar and combat system, but can be employed independently by ships with older or newer radar systems.
This article covers each variant in the Standard missile family, plus several years worth of American and Foreign Military Sales requests and contracts and key events; and offers the budgetary, technical, and geopolitical background that can help put all that in context.

Back in 2008, the Navy signaled its desire to its desire to incorporate the “far term sea-based terminal defense” capacity of the SM-6 into its Aegis system, with one hurdle being some ships’ radars being capable of handling the sensor data requirements. They then hoped for operational capability in 2015. Yesterday, Raytheon announced in a widely-parroted release that the Navy had indeed approved the SM-6 for additional Aegis systems, to include those Arleigh Burke-class guided missile destroyers from the 1994-keel-laid The Sullivans (DDG-68) onward.
This appears to put to rest concerns that the Zumwalt-class (DDG-1000) program wouldn’t be able to employ (see “Weapons” section) the standard family of missiles, although confirmation is being from both Raytheon and the Navy.

Latest updates[?]: Raytheon announced that the Navy has approved the SM-6 for additional Aegis systems, to include those Arleigh Burke-class guided missile destroyers from the 1994-keel-laid The Sullivans (DDG-68) onward.
The AEGIS Ballistic Missile Defense System seamlessly integrates the SPY-1 radar, the MK 41 Vertical Launching System for missiles, the SM-3 Standard missile, and the ship’s command and control system, in order to give ships the ability to defend against enemy ballistic missiles. Like its less-capable AEGIS counterpart, AEGIS BMD can also work with other radars on land and sea via Cooperative Engagement Capability (CEC). That lets it receive cues from other platforms and provide information to them, in order to create a more detailed battle picture than any one radar could produce alone.
AEGIS has become a widely-deployed top-tier air defense system, with customers in the USA, Australia, Japan, South Korea, Norway, and Spain. In a dawning age of rogue states and proliferation of mass-destruction weapons, the US Navy is being pushed toward a “shield of the nation” role as the USA’s most flexible and most numerous option for missile defense. AEGIS BMD modifications are the keystone of that effort – in the USA, and beyond.

Latest updates[?]: Another reform announcement: more delays, cost overruns TBD.

Under the SEA 4000 Air Warfare Destroyer program, Australia plans to replace its retired air defense destroyers with modern ships that can provide significantly better protection from air attack, integrate with the US Navy and other coalition partners, offer long-range air warfare defense for Royal Australian Navy task groups, and help provide a coordinated air picture for fighter and surveillance aircraft. Despite their name and focus, the ships are multi-role designs, with a “sea control” mission that includes area air defense, advanced anti-submarine operations, and the ability to fight other ships.
The Royal Australian Navy took a pair of giant steps in June 2007, when it selected winning designs for its keystone naval programs: Canberra Class LHD amphibious operations vessels, and Hobart Class “air warfare destroyers.” Spain’s Navantia made an A$ 11 billion clean sweep, winning both the A$ 3 billion Canberra Class LHD and the A$ 8 billion Hobart Class Air Warfare Destroyer contracts. The new AWD ships were scheduled to begin entering service with the Royal Australian Navy in 2013, but that date has now slipped to 2016 or so. A 2014 ANAO report examines why – and the answers aren’t pretty.
