EMALS/ AAG: Electro-Magnetic Launch & Recovery for Carriers

Feb 20, 2020 04:56 UTC

Latest updates[?]: General Atomics won a $25.2 million delivery order, which procures Electromagnetic Aircraft Launch System (EMALS) Depot Planning Phase II efforts, including depot level logistics support analysis, engineering support for logistics, supportability analysis, maintenance planning, reliability maintenance, technical manual development and engineering support as it directly correlates to depot planning for the USS Gerald Ford (CVN 78) and USS John F. Kennedy (CVN 79). More than 99 percent of the work on this contract will be performed in San Diego, with one-tenth of one percent of work on the contract taking place in Tupelo, Mississippi. Expected completion date is February 2022.

EMALS Components

As the US Navy continues to build its new CVN-21 Gerald R. Ford Class carriers, few technologies are as important to their success as the next-generation EMALS (Electro-MAgnetic Launch System) catapult. The question is whether that technology will be ready in time, in order to avoid either costly delays to the program – or an even more costly redesign of the first ship of class.

Current steam catapult technology is very entertaining when it launches cars more than 100 feet off of a ship, or gives naval fighters the extra boost they need to achieve flight speed within a launch footprint of a few hundred feet. It’s also stressful for the aircraft involved, very maintenance intensive, and not really compatible with modern gas turbine propulsion systems. At present, however, steam is the only option for launching supersonic jet fighters from carrier decks. EMALS aims to leap beyond steam’s limitations, delivering significant efficiency savings, a more survivable system, and improved effectiveness. This free-to-view spotlight article covers the technology, the program, and its progress to date.

Australia’s Hazard(ous) Frigate Upgrades: Done at Last

Feb 18, 2020 04:54 UTC

Latest updates[?]: Saab has signed an agreement with Australia to provide combat management systems for Navy's surface ships. According to the agreement, Saab will deliver its Next Generation’ Combat Management System (CMS) to Australia’s new Arafura Class offshore patrol vessels (OPVs) and the Supply class auxiliary oiler replenishment (AOR) ships. Saab will also modernize the 9LV CMS currently in use in the Anzac Class frigates and will provide the software for the future tactical interface for the Hobart class air warfare destroyer (AWDs) when their current CMS is modernized.

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. On the other hand, compromises made to meet short-term cost targets resulted in short service lives and decisions to retire, sell, or downgrade the ships instead of upgrading them.

Australia’s 6 ships of this class have served alongside the RAN’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 SEA 1390 project wasn’t what you’d call a success… but Australia accepted their last frigate in 2010, and the 4 remaining ships will serve until 2020.

INS Vikrant: India’s New Carrier

Jan 13, 2020 04:52 UTC

Latest updates[?]: The indigenously designed and developed Light Combat Aircraft (N) Mk1 has made a successful arrested landing on the India's biggest warship INS Vikramaditya on January 11. "With this feat, the indigenously developed niche technologies specific to deck based fighter operations have been proven," Indian Navy Spokesperson Vivek Madhwal told IANS. This will now pave the way to develop and manufacture the twin engine deck based fighter for the Indian Navy, he said. The Navy has created an aircraft carrier setting on the ground at its air base in Goa to operate these deck-based fighters, which use ski jump to take off and are recovered by arrestor wires on a carrier or STOBAR (short takeoff but arrested recovery) in Navy parlance.

Adm. Gorshkov: Before.

This free-to-view DID Spotlight article offers an in-depth look at India’s troubled attempt to convert and field a full-size aircraft carrier, before time and wear force it to retire its existing naval aviation and ships.

India faced 2 major challenges. One was slipping timelines, which risked leaving them with no aircraft carriers at all. The other challenge involved Vikramaditya’s 3-fold cost increase, as Russia demanded a re-negotiated contract once India was deeper into the commitment trap. The carrier purchase has now become the subject of high level diplomacy, involving a shipyard that can’t even execute on commercial contracts. A revised deal was finally signed in March 2010, even as deliveries of India’s new MiG-29K naval fighters got underway – but now Russia still has to make good. This article tracks the changes India is making to its new aircraft carrier, key characteristics, and a full history of contracts and events affecting this carrier and its planned aircraft contingent.

DDG Type 45: Britain’s Shrinking Air Defense Fleet

Oct 09, 2019 04:56 UTC

Latest updates[?]: Babcock International won a deal for for the Gun System Automation (GSA) 9 in-service support contract with the Ministry of Defense supporting the UK Royal Navy. The contract will provide support for all aspects of GSA9 support including Electro Optical Gunfire Control System (EOGCS), the Electro Optical Sensor Platforms (EOSPs), the Quick Pointing Devices (QPD) and below decks equipment of six Control Consoles, Gun Allocation Subsystem, Gunnery Check Fire System and two Maintenance and Analysis Facilities (MAF). The deal includes an option to be extended by two years and will be carried out from the company’s Devonport and Portsmouth facilities in the UK, delivering support for the Navy’s Type 45 Daring Class destroyers and management of the supply chain for the work.

Daring Class

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.

MFTA: The US Navy’s New Towed Array for Naval Detection

Sep 23, 2019 04:56 UTC

Latest updates[?]: The US Navy awarded Lockheed Martin a $24.7 million cost-plus-fixed-fee contract to develop the first production unit fabrication and qualification of the TB-37X Multi-Function Towed Array (MFTA) System. The legacy TB-37/U MFTA is an integral part of the AN/SQQ-89A(V)15 Undersea Warfare Combat System Improvement Program for the Arleigh Burke Class guided missile destroyers (DDG-51), Ticonderoga Class missile cruisers (CG-47) and Zumwalt Class destroyers. The TB-37X MFTA shall incorporate next-generation telemetry to mitigate reliability and obsolescence issues experienced with the legacy TB-37/U MFTA. The TB-37X will be deployed on additional platforms, including Littoral Combat Ship (LCS) and Next Generation Guided Missile Frigates (FFG(X)). Lockheed will perform work in Liverpool, New York; Millersville, Maryland; Marion, Massachusetts; Cleveland, Ohio; and Albuquerque, New Mexico, and is expected to be completed by October 2026.

Naval technologies have advanced on many fronts, but one of the most significant is the growing roster of diesel-electric submarines that boast exceptional quietness. Some of the newer AIP (Air-Independent Propulsion) models even have the ability to operate without surfacing for a week or two at a time. In exercises against the US Navy, diesel-electric submarines have successfully ‘killed’ their nuclear counterparts, and in 2006, a Chinese submarine reportedly surprised a US carrier battlegroup by surfacing within it.

The US Navy is slowly moving to beef up anti-submarine capabilities that had been neglected since the end of the Cold War, and other navies are also beginning to adjust. One of the first areas that requires attention is improved detection. That means wider coverage areas, longer baselines, better sonar and other detection systems, and greater use of small unmanned platforms on the surface and underwater. With UUV/USV platforms still maturing, and almost every advanced navy except the Chinese getting smaller due to the cost of new warships, towed systems are a natural place to start.

Mid-Life Extensions for USN LSDs

Sep 11, 2019 04:58 UTC

Latest updates[?]: BAE Systems Norfolk won a $11.9 million contract modification for additional growth requirements, including actions taken during Hurricane Florence, identified during the execution of the USS Tortuga Fiscal 2018 Modernization Period Chief of Naval Operations availability. USS Tortuga was originally commissioned in November 1990 and has been part of the US Navy’s LSD / CG-class modernization program since 2016. The keel on the vessel was initially laid on 23 March 1987. At the start of the Tortuga modernization process in May 2016, BAE Systems’ Norfolk shipyard was awarded a $17.7 million contract. The Tortuga or LSD 46 is a Whidbey Island Class dock landing ship. Work will take place in Norfolk, Virginia and estimated completion will be in November this year.

LSD 43 off Haiti

The LSD MSMO was developed to provide extended dry docking, modernization, upgrades, and repairs to the LSD-41 Whidbey Island and related LSD-49 Harpers Ferry Classes of amphibious landing ships, which were commissioned between 1985-1998. The classes are highly similar, but the slightly larger Harpers Ferry Class reduces the number of onboard LCAC hovercraft from 4 to 2, in exchange for more cargo capacity. Two ships of these classes are being upgraded each year through 2013, and the last ship will be modernized in 2014. LSD MSMO aims to keep all 12 remaining ships of these classes in service and mission-capable to 2038.

These 186-190m, 14,460-14,850 tonne US Navy LSD ships are designed to carry Marines and equipment close to shore, then land them by launching onboard craft from their well decks. They’re similar in size to the earlier Austin/Cleveland Class LPDs, but are much smaller than either the new LPD-17 San Antonio Class, or the carrier-size LHA-1 Tarawa and LHD-1 Wasp Classes. Despite these characteristics, or perhaps because of them, their flexibility and numbers have made them among the US Navy’s most-used ships for several years running.

SSDS: Quicker Naval Response to Cruise Missiles

Aug 19, 2019 04:56 UTC

Latest updates[?]: Lockheed Martin won a $56 million deal for combat system engineering support on the Ship Self-Defense System (SSDS). Under the contract, the SSDS combat system engineering agent and software design agent primary deliverables will be SSDS tactical computer programs, program updates and associated engineering, development and logistics products. The contract will manage the in-service SSDS configurations as well as adapt and integrate new or upgraded war-fighting capabilities. Lockheed will perform work in Moorestown, New Jersey and San Diego, California. Estimated completion date is in December.

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.

Carrier Signal: China’s Naval Aviation

Jul 16, 2019 04:52 UTC

Latest updates[?]: According to the South China Morning Post, China is hoping to develop a nuclear-powered aircraft carrier by first putting the reactors on icebreakers. This approach was carried out by the Soviet Union when they wanted to build their own nuclear-powered aircraft carrier. Russia has so far been invited by China to develop the latter’s first nuclear-powered icebreaker. “China really needs a more powerful, nuclear-powered aircraft carrier to catapult its superheavy carrier-based fighter jet, the J-15,” the SCMP quotes Naval expert Li Jie. Although China already has nuclear submarines, the systems they use are unsuitable for carriers as they are not powerful enough.

SU-33s: folded, landing

In 1998, the former Russian carrier Varyag was bought by a Chinese firm for use as a “tourist attraction.” Nobody believed that, and by 2005, she was in drydock for secret refits. Still, a carrier needs planes. Near the end of October 2006, Russia’s Kommersant newspaper revealed that Russian state-run weapon exporter Rosoboronexport was in negotiations with China to deliver SU-33s, a variant of Sukhoi’s SU-27 Flanker with forward canards, foldings wings, an arrester hook, a reinforced structure, and other modifications that help it deal with carrier operations and landings.

By 2009, Russian media were reporting a breakdown of negotiations, citing low order numbers and past pirating of Russian SU-27/30 designs. China built on that prior piracy to produce its SU-33 look-alike “J-15,” with the reported assistance of an SU-33 prototype bought from the Ukraine. It’s now 2012, and China’s myriad deceptions have served their purpose. They don’t have an active carrier force yet, but they’re very close.

Australia’s Canberra Class LHDs

May 30, 2019 04:52 UTC

Latest updates[?]: The Australian Navy was tailed by the Chinese Military as it travelled towards Vietnam on the South Chinese Sea. The HMAS Canberra was ending a three-month-long tour of seven Asian nations involving three other Australian warships, aircraft and more than 1,200 defense personnel. The ships journeyed near islands controversially claimed by Beijing. Defense officials confirmed, that the ships had a "professional" and "friendly" interaction with the People's Liberation Army during Indo-Pacific Endeavour 2019, an Australian Defense Forces regional engagement mission.

Canberra concept

In May of 2006 the Royal Australian Navy announced its decision to expand its naval expeditionary capabilities. HMAS Manoora and Kanimbla would be replaced with substantially larger and more capable modern designs, featuring strong air support. Navantia and Tenix offered a 27,000t Landing Helicopter Dock (LHD) design that resembled the Strategic Projection Ship (Buque de Proyeccion Estrategica) under construction for the Spanish Navy. The DCNS-Thales Australia team, meanwhile, proposed a variation of the 21,300t Mistral Class that is serving successfully with the French Navy.

Navantia’s larger design eventually won, giving the Spanish firm an A$ 11 billion clean sweep of Australia’s “Air Warfare Destroyer” and LHD programs. These 5 ships will be the core of Australia’s future surface navy. The future HMAS Canberra and HMAS Adelaide will be able to serve as amphibious landing ships, helicopter carriers, floating HQs and medical facilities for humanitarian assistance, and launching pads for UAVs or even short/vertical takeoff fighters.

The Dokdo Class: an LHD for the ROK

May 23, 2019 04:52 UTC

Latest updates[?]: South Korea’s second Dokdo Class helicopter carrier started Sea Trials, Jane’s reports. The Dokdo Class Landing Platform Helicopter (LPH) ships of the Korean Navy act as a command and control platform for the maritime mobile fleet and supports three-dimensional landing operations as well as maritime air operations. The Navy launched the lead ship, the ROKS Dokdo, in July 2005 and commissioned it two years later. Dokdo is the largest vessel in the South Korean Navy. The hull is divided into four decks to accommodate helicopters, assault amphibious vehicles, landing craft air cushion, tanks and trucks. The second ship will be named ROKS Marado once commissioned. Marado is a 199 meter long LPH ship that displaces 14,500 tonnes and features a through-deck flight operations area with five landing spots. It is able to carry up to 10 UH-60 helicopters, about 700 embarked troops, and 10 main battle tanks and associated support vehicles.

ROKS Dokdo

Australia isn’t the only Pacific Rim country looking to modernize its Navy these days. China’s rapid shipbuilding program and work on its aircraft carrier project gets a lot of attention – but just to the east, South Korea is fielding its own AEGIS-equipped “air warfare destroyer,” while picking up new capabilities via a new class of amphibious assault LHD ship. Sound familiar? Hobart and Canberra Class, meet the KDX-III King Sejong Class AEGIS destroyer (launched May 2007) and the new “LPH” Dokdo Class LHD (commissioned July 2007).

The 199-meter, 18,860-ton Dokdo Class officially has the less aggressive designation of LPH (landing platform, helicopter), but its well deck and amphibious assault capabilities place it within the LHD category…
