Britain Upgrading Her Dukes [Type 23 Frigates]

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.

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.

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.

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.

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.

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).

Indian Naval Air Defenses: Another Avoidable Crisis

India’s dysfunctional political and procurement systems have created another security crisis for its military, by creating a growing risk that a number of its ships will have weakened defenses against aerial attack.

The problem stems from the government’s inability to issue a follow-on contract for Barak-1 missiles, last ordered in October 2000 when India bought 9 systems and 200 missiles in a pair of deals with IAI and RAFAEL worth INR 15.1 billion (then around $326 million). The blockage is delaying key upgrades, and missile stocks for existing ships are critically low and shrinking. As usual, the culprit is a combination of a bureaucratic culture divorced from operational needs, inability to make decisions, and overly rigid rules.

SSDS: Quicker Naval Response to Cruise Missiles

Right now, in many American ships beyond its Navy’s 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, seconds of delay can be fatal. Seconds of unnecessary delay are unacceptable.

Hence Raytheon’s Ship Self Defense System (SSDS), which is currently funded under the US Navy’s Quick Reaction Combat Capability program. It’s widely used as a combat system in America’s carrier and amphibious fleets. That can be challenging for its developers, given the wide array of hardware and systems it needs to work with. Consistent testing reports indicate that this is indeed the case, and SSDS has its share of gaps and issues. It also has a series of upgrade programs underway, in order to add new capabilities. Managing these demands effectively will have a big impact on the survivability of the US Navy’s most important power projection assets.

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.

CEC: Cooperative Engagement for Fleet Defense

Cooperative Engagement Capability (CEC) is the US Navy’s secret weapon. Actually, it’s not so secret. It’s just that its relatively low price means often leads people to overlook the revolutionary change it creates for wide-area fleet air and ballistic missile defense.

CEC is far more than a mere data-sharing program, or even a sensor fusion effort. The concept behind CEC is a sensor netting system that allows ships, aircraft, and even land radars 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 of them could generate on its own. The data is then shared among all ships and participating systems, using secure frequencies. It’s a simple premise, but a difficult technical feat. With huge implications.

This DID FOCUS Article explains those mechanics and implications. It will also track ongoing research, updates, and contracts related to CEC capabilities from 2000 forward.
