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).

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 FOCUS Article with respect to the Phalanx CIWS. Recent developments include a US Army buy, for use on land…

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 pair of support contracts, plus international orders for associated equipment…

The Royal Australian Navy took a pair of giant steps toward its future force in June of 2007, when it selected winning designs for 2 new Canberra Class LHD amphibious operations vessels, and 3 new Hobart Class air warfare destroyers.

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 a task force. Under the SEA 4000 program, Australia plans to replace its retired air defense destroyers with a modern system that can provide significantly increased protection from air attack for troops being transported and deployed, 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 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.

This DID FOCUS Article explains the details of the SEA 4000 program, offers some details re: the winning design plus the losing “Evolved DDG-51” option, and covers the contracts and key events to date. Recent events include a request for AEGIS and cooperative Engagement equipment…

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 include the launch of Austal/GD’s LCS 2 Independence…

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 in service with 13 navies worldwide. The most common variant is the RIM-66K-L/ SM-2 Standard Block IIIB, which entered service in 1998. It includes a number of modifications over previous versions, including greater capability at even lower altitudes, a more powerful fragmentation warhead, and a side-mounted infrared seeker developed in the Missile Homing Improvement Program (MHIP) to supplement the missile’s semi-active radar guidance system. These missiles work best when paired with the AEGIS radar and combat system, but can be employed independently.

DID details Raytheon’s recent US contracts related to the Standard Missile family from April 2006 onward, and also adds some budgetary and technical background that can help put them in context. New material is indicated in green type. The latest news involves a billion dollar joint contract for SM-3 missiles by the USA and Japan, followed closely by a landmark event: the successful destruction of a failing US satellite by a modified SM-3 (incl. photos, video, etc.)...

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…

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 request from Australia…

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, 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, was the sole US production version.

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 deemed upgrading their electronics, radars et. al. for new communications realities and advanced missile threats to be prohibitively expensive. 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 Australia’s more modern ANZAC Class frigates, which are undergoing upgrades of their own in hopes that it will help them handle the reality of modern anti-ship missiles. With the SEA 4000 Hobart Class air warfare frigates just a gleam in their eye, the government looked for a way to upgrade their FFG-7 “Adelaide Class” to keep them in service until 2020 or so. Recent reports indicate, however, that this A$ 1.46 billion SEA 1390 project has not gone very well…

HMS Sutherland

Brtiain’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 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 defence 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…

MU90 Eurotorp

In December 2005, “Beyond Armaris: Thales “Buys” Minority Stake in DCN” covered the government-prodded merger of Thales naval business with state-owned DCN, to create DCNS. That agreement excluded some naval items like electronics, but it did include Thales’ 24% share in Eurotorp, the European lightweight torpedo consortium that was officially founded in 1993 as a joint venture between DCN International (26%), Thomson-CSF (now Thales, 24%) and Whitehead (now Finmeccanica, 50%).

The DCNS transaction was not concluded until March 2007, and now the Eurotorp consortium has taken the next step by creating a more wide-ranging set of joint ventures in underwater weapons systems. The longer-term goal remains European integration, and the 3 CEOs have said they would consider opening the alliance to other European players at some point….
