Hobart Class Ships: Aussie Anti-Air Umbrella

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.

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

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.

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.

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.

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.

Raytheon’s Standard Missile Naval Defense Family (SM-1 to SM-6)

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.

DDG Type 45: Britain’s Shrinking Air Defense Fleet

The 5,200t Type 42 Sheffield Class destroyers were designed in the late 1960s to provide fleet area air-defense for Britain’s Royal Navy, after the proposed Type 82 air defense cruisers were canceled by the Labour Government in 1966. Britain built 14 of the Type 42s, but these old ships are reaching the limits of their operational lives and effectiveness.

To replace them, the Royal Navy planned to induct 12 Type 45 Daring Class destroyers. The Daring class would be built to deal with a new age of threats. Saturation attacks with supersonic ship-killing missiles, that fly from the ship’s radar horizon to ship impact in under 45 seconds. The reality of future threats from ballistic missiles, and WMD proliferation. Plus a proliferation of possible threats involving smaller, hard to detect enemies like UAVs. Overall, the Type 45s promise to be one of the world’s most capable air defense ships – but design choices have left the cost-to-value ratio uncertain, and limited the Type 45s in other key roles. A reduced 6-ship program moved forward.

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

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).

Modernizing Canada’s Halifax Class Frigates

Launched between 1988-1995, and commissioned between 1992-1996, Canada’s 12 City Class (now Halifax Class) frigates currently form the high end of its naval capabilities. The Canadian Navy has declined drastically from its post-WWII status as the world’s 4th largest navy, and the Halifax Class itself is finding that its open-ocean design is not suited to cope with modern littoral threats and improving anti-ship missiles. Replacement vessels are still many years away, which means that the 4,750t frigates will need to be modernized within the limits of their design if they are to remain effective.

Canada’s government has decided to fund that modernization, much as Australia and New Zealand are modernizing the Halifax Class’ ANZAC Frigate contemporaries. Refits are scheduled to begin with HMCS Halifax in 2010, and that ship is scheduled to re-enter service about 18 months later in 2012. By 2017, all 12 frigates are scheduled to be upgraded as part of a C$ 3.1 billion (about $2.9 billion) program. This DII Spotlight article explains the scope of the upgrades, notes the current systems, and covers the contracts and developments involved.

LCS & MH-60S Mine Counter-Measures Continue Development

The US Navy currently uses large CH-53/MH-53 helicopters and towed sleds to help with mine clearance work, but they hope to replace those old systems with something smaller and newer. The MH-60S helicopter’s Airborne Mine Counter-Measures (AMCM) system adds an operator’s station to the helicopter cabin, additional internal fuel stores, and towing capability, accompanied by a suite of carried systems that can be mixed and matched. AMCM is actually 5 different air, surface and sub-surface mine countermeasures systems, all deployed and integrated together in the helicopter.

While the US Navy develops AMCM, and complementary ship-launched systems for use on the new Littoral Combat Ships, new minehunter ship classes like the Ospreys are being retired by the US Navy and sold. All in an era where the threat of mines is arguably rising, along with tensions around key chokepoints like the Suez Canal and Strait of Hormuz.

This article explains the components involved (AQS-20, ALMDS, AMNS, OASIS, RAMICS; COBRA, RMS, SMCM), chronicles their progress through reports and contracts, and provides additional links for research.
