Phalanx CIWS: The Last Defense, On Ship and Ashore

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.

LCS: The USA’s Littoral Combat Ships

Exploit simplicity, numbers, the pace of technology development in electronics and robotics, and fast reconfiguration. That was the US Navy’s idea for the low-end backbone of its future surface combatant fleet. Inspired by successful experiments like Denmark’s Standard Flex ships, the US Navy’s $35+ billion “Littoral Combat Ship” program was intended to create a new generation of affordable surface combatants that could operate in dangerous shallow and near-shore environments, while remaining affordable and capable throughout their lifetimes.

It hasn’t worked that way. In practice, the Navy hasn’t been able to reconcile what they wanted with the capabilities needed to perform primary naval missions, or with what could be delivered for the sums available. The LCS program has changed its fundamental acquisition plan 4 times since 2005, and canceled contracts with both competing teams during this period, without escaping any of its fundamental issues. Now, the program looks set to end early. This public-access FOCUS article offer a wealth of research material, alongside looks at the LCS program’s designs, industry teams procurement plans, military controversies, budgets and contracts.

Serious Dollars for AEGIS Ballistic Missile Defense (BMD)

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.

RIM-162 ESSM Missile: Naval Anti-Air in a Quad Pack

RIM-162: sections

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.

USN Ship Protection: From “Slick 32s” to SEWIP

“Slick 32”

The US Navy’s AN/SLQ-32 ECM (Electronic Countermeasures) system uses radar warning receivers, and in some cases active jamming, as the part of ships’ self-defense system. The “Slick 32s” provides warning of incoming attacks, and is integrated with the ships’ defenses to trigger Rapid Blooming Offboard Chaff (RBOC) and other decoys, which can fire either semi-automatically or on manual direction from a ship’s ECM operators.

The “Slick 32” variants are based on modular building blocks, and each variant is suited to a different type of ship. Most of these systems were designed in the 1970s, however, and are based on 1960s-era technology. Unfortunately, the SLQ-32 was notable for its failure when the USS Stark was hit by Iraqi Exocet missiles in 1987. The systems have been modernized somewhat, but in an era that features more and more supersonic ship-killing missiles, with better radars and advanced electronics, SLQ-32’s fundamental electronic hardware architecture is inadequate. Hence the Surface Electronic Warfare Improvement Program (SEWIP).

South Korea Beefs Up Anti-Air Defenses as North Blusters

SM-2 salvo

North Korea’s recent aggressive actions, including abrogation of the 1953 ceasefire, nuclear detonation, and testing of short and long-range missiles, has increased international tensions and directly threatened its southern neighbor. South Korea has been modernizing its defenses for some time now, and a recent request for Standard Missile 2 (SM-2) systems from the United States is a case in point.

The US Defense Security Cooperation Agency announced May 26/09 [PDF] South Korea’s official request to buy 46 SM-2 Block IIIA missiles, 35 SM-2 Block IIIB missiles, 3 SM-2 Block IIIB Telemetry Missiles for testing, 84 SM-2 missile containers, and associated test and support equipment, spare and repair parts, training, and other forms of support. The estimated cost is $170 million, and the prime contractor will be Raytheon in Tucson, AZ. The sale would require temporary travel for U.S. Government or contractor representatives to the Republic of Korea for in-country training, as a recurring requirement during the life of the missile systems.

How does this purchase fit into South Korea’s overall defense plans?

Britain Upgrading Her Dukes [Type 23 Frigates]

HMS Sutherland

Britain’s Type 23 Duke Class frigates were originally envisioned as pure anti-submarine vessels, to the extent of being planned with no other armament. The 1982 Falklands War quickly put paid to that idea, however, and the Type 23s would end up being commissioned from 1989-2001 and fitted with a main gun, Sea Wolf short range anti-air missiles, and Harpoon anti-ship missiles to accompany her torpedoes, decoys, et. al. These changes turned the frigates from specialized sub-hunters into versatile multi-role combatants that play a key role in the British fleet. The Royal Navy is set to continue shrinking in size (see esp. diagram) due to rising ship costs, and even though key platforms like aircraft carriers and amphibious ships may be more capable, the mid-tier combat role filled by frigates is not slated for new construction any time soon. As such, upgrading the Navy’s 13 remaining Type 23s to keep them in service is vitally important to Britain’s future force.

As part of those operational upgrade efforts, the Type 23 frigates will receive: Sonar 2087 towed sonars, the Royal Navy’s latest and most sophisticated submarine hunting system (Thales UK, GBP 166 million for machines that go ‘ping!’); Upgraded vertical-launch Sea Wolf Block 2 air defense missiles to help counter supersonic anti-ship missiles (BAE Systems Insyte with MBDA, GBP 300 million); an improved 114mm Vickers Mk 8 Mod 1 main gun, capable of firing long-range ammunition; and a reshaped stern to cut fuel use. Upgrades are also being performed during maintenance periods, some of which are significant to the ship’s overall capabilities. This article covers a number of upgrade efforts, from 2005-2015.

Lockheed to Upgrade Japanese AEGIS Destroyer for ABM Use

JS Kongou

Lockheed Martin Maritime Sensors and Systems won a $124 million cost-plus-award-fee contract modification to upgrade Japan’s Kongo-Class AEGIS destroyer JS Kongo [DDG-173] to give it AEGIS Ballistic Missile Defense Block 2004 capability. Japan’s Kongo-Class destroyers are based on the USA’s Flight II DDG 51 Arleigh Burke Class, but feature many modifications both internally and externally. The Kirishima itself was posted to the Indian Ocean as part of Japan’s contribution to the war on terror, acting as flagship for the Japanese Maritime Self Defense Force.

DID has covered related Japanese contracts, including cooperation with the USA on missile defense and a related $400 million order for naval ABM components and services. Work on this contract will take place in Moorestown, NJ (78%); Baltimore, MD (15%); Eagan, MN (4%); and Aberdeen, SD (3%); and should be complete by November 2007. The project was not bid out, but was rather awarded by the Naval Sea Systems Command in Washington, DC under contracting activity N00024-03-C-6110. See also Lockheed release.

June 11/15: South Korea has requested the sale of the Aegis Combat System through a Foreign Military Sale. The potential sale of three of the systems, as well as auxiliary equipment, could be worth $1.9 billion and comes weeks after the North tested a “submarine-launched” missile. The ACS comprises the SPY-1 radar, Display System and Underwater Countermeasure System, with the Aegis system also capable of operating in a Ballistic Missile Defense capacity.

May 27/15: Lockheed Martin was handed a $69.7 million contract to upgrade two Japanese Defense Force Atago-class Aegis-equipped ships through a Foreign Military Sale. The JDF is reportedly planning on building an additional pair of Atago-class ships, with Lockheed Martin having previously been awarded a contract in support of the class.

Aegis Program Adds SM-6 to Mix for More Ships

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.

Hobart Class Ships: Aussie Anti-Air Umbrella

F100 visits Sydney

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.
