Airfields Afloat: The USA’s New Gerald Ford Class Super-Carriers

Some nations have aircraft carriers. The USA has super-carriers. The French Charles De Gaulle Class nuclear carriers displace about 43,000t. India’s new Vikramaditya/ Admiral Gorshkov Class will have a similar displacement. The future British CVF Queen Elizabeth Class and related French PA2 Project are expected to displace about 65,000t, while the British Invincible Class carriers that participated in the Falklands War weigh in at just 22,000t. Invincible actually compares well to Italy’s excellent new Cavour Class (27,000t), and Spain’s Principe de Asturias Class (17,000t). The USA’s Nimitz Class and CVN-21 Gerald R. Ford Class, in contrast, fall in the 90,000+ tonne range. Hence their unofficial designation: “super-carriers”. Just one of these ships packs a more potent air force than many nations.

As the successor to the 102,000 ton Nimitz Class super-carriers, the CVN-21 program aimed to increase aircraft sortie generation rates by 20%, increase survivability to better handle future threats, require fewer sailors, and have depot maintenance requirements that could support an increase of up to 25% in operational availability. The combination of a new design nuclear propulsion plant and an improved electric plant are expected to provide 2-3 times the electrical generation capacity of previous carriers, which in turn enables systems like an Electromagnetic Aircraft Launching System (EMALS, replacing steam-driven catapults), Advanced Arresting Gear, and integrated combat electronics that will leverage advances in open systems architecture. Other CVN-21 features include an enhanced flight deck, improved weapons handling and aircraft servicing efficiency, and a flexible island arrangement allowing for future technology insertion. This graphic points out many of the key improvements.

DID’s CVN-21 FOCUS Article offers a detailed look at a number of the program’s key innovations, as well as a list of relevant contract awards and events.

Adding Arleigh Burkes: H.I.I. Steps Forward for DDG-51 Restart

In April 2009 Bath and Ingalls agreed to the Navy’s surface combatant plans, thus heralding a significant restructuring within the American naval shipbuilding community. Under the agreements, the USA would end production at 3 Graf Spee sized DDG-1000 Zumwalt Class “destroyers,” but shift all production from the Congressionally-mandated joint arrangements to General Dynamics Bath Iron Works in Maine, which had already made program-related investments in advanced shipbuilding technologies.

Northrop Grumman (now Huntington Ingalls Industries) would retain its DDG-1000 deckhouse work, but their main exchange was additional orders for DDG-51 Arleigh Burke Class destroyers. Their Ingalls yard in Pascagoula, Mississippi would continue building the DDG-51 destroyers, beginning with 2 ordered in FY 2010-2011.

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

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.

Australia’s Canberra Class LHDs

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 USA’s DDG-1000 Zumwalt Class Program: Dead Aim, Or Dead End?

DID’s FOCUS Article for the DDG-1000 Zumwalt Class “destroyer” program covers the new ships’ capabilities and technologies, key controversies, associated contracts and costs, and related background resources.

The ship’s prime missions are to provide naval gunfire support, and next-generation air defense, in near-shore areas where other large ships hesitate to tread. There has even been talk of using it as an anchor for action groups of stealthy Littoral Combat Ships and submarines, owing to its design for very low radar, infrared, and acoustic signatures. The estimated 14,500t (battlecruiser size) Zumwalt Class will be fully multi-role, however, with undersea warfare, anti-ship, and long-range attack roles. That makes the DDG-1000 suitable for another role – as a “hidden ace card,” using its overall stealth to create uncertainty for enemy forces.

At over $3 billion per ship for construction alone, however, the program faced significant obstacles if it wanted to avoid fulfilling former Secretary of the Navy Donald Winter’s fears for the fleet. From the outset, DID has noted that the Zumwalt Class might face the same fate as the ultra-sophisticated, ultra-expensive SSN-21 Seawolf Class submarines. That appears to have come true, with news of the program’s truncation to just 3 ships. Meanwhile, production continues.

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.

The Dokdo Class: an LHD for the ROK

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…

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.

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.

INS Vikrant: India’s New Carrier

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.
