DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. 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.” This DID’s FOCUS article offers in-depth research and coverage of the Hobart Class competition and program organization, along with the new “air warfare destroyer’s” capabilities, and associated contracts, and related developments.

Australia’s ANZAC Class (Meko 200 derivative) and Adelaide Class (FFG-7 Adelaide Class) frigates have limited air defense capabilities. They would be hard-pressed to survive against modern anti-ship missiles, and even planned ANZAC upgrades would not make them suitable for protecting an entire task force by themselves. Under the SEA 4000 Air Warfare Destroyer program, Australia plans to replace its retired air defense destroyers with a modern system 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 also includes advanced anti-submarine and surface warfare capabilities.

After a long campaign that supported the creation and detailed evaluation of 2 fleshed out designs, the A$ 8 billion program has a winner. To the surprise of some observers, Australia’s 3 new “air warfare destroyers” will be… ‘Australianized’ F100 AEGIS frigates. Spain’s Navantia made an A$ 11 billion clean sweep, winning both the Canberra Class LHD and the 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 2014-2015.

Recent events include 3 sets of contracts for IRST, decoy, and navigation systems…

RIM-162: sections
(click to view full)

The RIM-162 Evolved Sea Sparrow Missile (ESSM) is used to protect ships from attacking missiles and aircraft, and is 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.

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 customers outside this consortium include Japan, Korea, and the United Arab Emirates.

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 latest addition is a support contract…

HMAS Adelaide

The FFG-7 Oliver Hazard Perry Class frigates make for a fascinating defense procurement case study. To this day, the ships are widely touted as a successful example of cost containment and avoidance of requirements creep – both of which have been major weaknesses in US Navy acquisition. The result was a capable 3,600t-4,100t anti-submarine platform, with some secondary air defense and anti-ship capabilities via its SM-1 Standard and RGM-84 Harpoon missiles, that could be bought in large enough numbers to fill the Navy’s needs. The ships’ hull twisting and cracking problems were solved early on, and they proved they could take a hit and stay afloat when the USS Stark was struck by 2 Iraqi Exocet missiles during the Iran/ Iraq war. By FFG-36, the “FFG-7 Flight III (Long)” variant was the sole US production version, with an extra 8 feet of length that let it accommodate larger and more capable SH-60 Seahawk helicopters instead of the SH-2 Sea Sprites.

The bad news was the flip side of the good news. Very little reserved space for growth (39 tons in the original design), and the standard inflexible, proprietary electronics of the time, made updates problematic. So problematic, in fact, that the US Navy gave up on the idea of upgrading their electronics, radars et. al. for new communications realities and advanced missile threats. Instead, they removed the 25 “FFG-7 Short” ships from inventory via bargain basement sales to allies or outright retirement, after an average of only 18 or so years of service. The remaining 30 ships received minor upgrades but had their no-longer standard SM-1 missiles removed – and with them, any air defense role. They do not operate in dangerous areas without cover from high-end AEGIS destroyers and cruisers.

Australia’s 6 ships of this class have served alongside the Navy’s more modern ANZAC Class frigates, which are undergoing upgrades of their own to help them handle the reality of modern anti-ship missiles. With the SEA 4000 Hobart Class air warfare frigates still just a gleam in an admiral’s eye, the government looked for a way to upgrade their FFG-7 “Adelaide Class” to keep them in service until 2020 or so. The A$ 1.46 billion SEA 1390 project has not gone very well… though the new Labor government is working to put a better face on it.

HMCS Montreal & sub:
HMCS Windsor

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 DID article explains the scope of the upgrades, notes the current systems, and covers the contracts and developments involved…

Right now, in many American ships beyond the top-tier AEGIS destroyers and cruisers, the detect-to-engage sequence against anti-ship missiles requires a lot of manual steps, involving different ship systems that use different displays. When a Mach 3 missile gives you 45 seconds from appearance on ship’s radar to impact, however, seconds of delay can be fatal. Seconds of unnecessary delay, are unacceptable.

Hence Raytheon’s Ship Self Defense System (SSDS), which uses software and commercial off-the-shelf (COTS) electronics to turn incoming data from several systems (radar, radar warning receivers, combat identification, electro-optics) into a single picture of prioritized threats. SSDS will then recommend an engagement sequence for the ship’s crew, or (in automatic mode) fire some combination of jamming transmissions, chaff or decoys, and/or weapons against the oncoming threat. The entire ship’s combat system concept, including the sensors and weapons, is known as Quick Reaction Combat Capability (QRCC) – and SSDS is the key element that ties it all together.

SSDS began Operational Evaluation (OPEVAL) in 1997 on USS Ashland [LSD 48], a Whidbey Island Class amphibious assault ship, and will soon begin equipping America’s new carriers…

General Dynamics Team
Trimaran LCS Design
(click to enlarge)

The Littoral Combat Ship (LCS) is the U.S. Navy’s newest surface combatant class. Optimized for shallow seas and operations within 100 miles of shore, but deployable across the ocean, LCS ships are a centerpiece of the USA’s new focus on littoral warfare. They will help to counter growing “asymmetric” threats like coastal mines, quiet diesel submarines, global piracy, and terrorists on small fast attack boats. They will also perform intelligence gathering and scouting using helicopters and UAVs, offer some ground combat support capabilities, and share tactical information with other Navy aircraft, ships, submarines, and joint units. Swappable “mission modules,” UAV robot aircraft, and robotic UUV and USV vehicles will give these small ships the specialized capabilities they require for each of these roles – and the quick-replace adaptability they need to keep up.

At present, 2 teams are competing for the final LCS design. The General Dynamics team is offering a futuristic but practical high-speed trimaran based on Austal designs and experience. The Lockheed Martin team offers a high-speed semi-planing monohull based on Fincantieri designs that have set trans-Atlantic speed records. Team Lockheed’s efforts have run into serious trouble, including cancellation of the contract for their second ship. The General Dynamics/Austal team hit the same rocks soon afterward, in part because of the US Navy’s unusual proposal for future business arrangements.

DID places recent developments in context by explaining a bit more about the US Navy’s new surface combatant; detailing the teams, key time line events, and contract awards under the program to date; and providing additional resources and links to complete our in-depth coverage. New material appears in green type. The latest updates involve a christening, a commissioning and post-shakedown contract, and mission module acceptance… and the US Navy declining its planned FY 2008 LCS purchase.

Phalanx, firing
(click to view full)

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 (see video: MPEG | AVI, with hat tips to the good folks at Digg.com).

These capabilities have made it a crtical bolt-on sub-system for naval vessels around the world. As of Feb 28/07, More than 895 Phalanx systems had been built and deployed in the navies of 22 nations. The latest development is C-RAM/Centurion, a land-based system designed to defend against incoming artillery and mortars.

This is DID’s Spotlight article offering updated, in-depth coverage of the Phalanx CIWS. It 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. Recent developments include a new platform for Phalanx: a large truck with a hybrid engine…

SM-2 Launch w. AEGIS
(click to view full)

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 replace 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.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This article covers each variant in the Standard missile family, several years worth of American and Foreign Military Sales requests and contracts, key events, and the budgetary and technical background that can help put all that in context. New material is indicated in green type.

The latest news involves a large international contract for SM-2s…

SSN-23 in MSF at Kitsap
(click to view full)

Aug 11/08: The Watts-Healy Tibbitts joint venture in Honolulu, HI receives an initial $42.4 million increment to build a drive-in magnetic silencing facility at Beckoning Point, Naval Station Pearl Harbor. The 2nd increment will be funded in FY 2009 at $35.9 million, and the 3rd increment will be funded in 2010 at $6.6 million to finish the $84.8 million contract. The contract also contains an unexercised option, which would increase the cumulative contract value to $86.1 million.

The reason behind these expensive facilities is simple. Any mass of iron stressed in the earth’s magnetic field becomes a magnet. Riveting and other construction activities magnetize a ship, as do some operational activities. That magnetization then changes gradually when the ship is underway, depending on its heading and location. A magnetized object can be detected, of course, and magnetic field changes can also be used as a trigger for weapons like mines and homing torpedos. Magnetic Silencing Facilities provide deperming/ degaussing, which reduces the ship’s electromagnetic signature to a point that’s much closer to the earth’s natural level. Cryptome has a partial list of American MSFs, including some photos and links.

Work will be performed in Pearl Harbor, Hawaii and is expected to be complete by October 2010. This contract was competitively procured, with 41 offers solicited and 4 proposals received by the Naval Facilities Engineering Command, Pacific in Pearl Harbor, HI (N62742-08-C-1311).

CEC Concept
(click to enlarge)

Cooperative Engagement Capability (CEC) is a sensor netting system that allows many ships to pool their radar and sensor information together, creating a very powerful and detailed picture that’s much finer, more wide-ranging, and more consistent than any one ship could generate on its own. The data is then shared among all ships via secure frequencies.

Yet CEC is far more than a mere data-sharing program, or even a sensor fusion effort. Indeed, it may well be the most revolutionary capability available to the modern US Navy. This DID FOCUS Article explains CEC’s mechanics and implications; it will also track ongoing research, updates, and contracts related to CEC capabilities from 2000 forward. The latest item is a an order from the US Navy…
