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.

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.

The US Navy’s Dual Band Radars

The US Navy’s newest light cruiser and aircraft carrier designs offer a wide array of new technologies. One is the Dual-Band Radar (DBR) system, which can be scaled up or down for installation in the new DDG-1000 Zumwalt Class “destroyers”, and the CVN-21 Gerald R. Ford Class aircraft carriers.

The DBR concept involves a significant change from current naval design approaches, and that change is not without risk. The USA’s GAO audit office remains concerned that key tests may not happen before the radar is installed on new ships, and any more development or testing snags could put much larger programs at risk. In April 2009, a successful full-power “lightoff” of both DBR radars was encouraging, but 2010 saw a major program shift. Sharp drops in the planned number of DDG-1000 destroyer created a per-ship cost crisis. Part of the response involved a shift to a single X-band SPY-3 radar for the Zumwalt Class, leaving DBR as a dual-band SPY-3/ SPY-4 solution only on America’s new carriers.

MQ-8 Fire Scout VTUAV Program: By Land or By Sea

A helicopter UAV is very handy for naval ships, and for armies who can’t always depend on runways. The USA’s RQ/MQ-8 Fire Scout Unmanned Aerial Vehicle has blazed a trail of firsts in this area, but its history is best described as “colorful.” The program was begun by the US Navy, canceled, adopted by the US Army, revived by the Navy, then canceled by the Army. Leaving it back in the hands of the US Navy. Though the Army is thinking about joining again, and the base platform is changing.

The question is, can the MQ-8 leverage its size, first-mover contract opportunity, and “good enough” performance into a secure future with the US Navy – and beyond? DID describes these new VTUAV platforms, clarifies the program’s structure and colorful history, lists all related contracts and events, and offers related research materials.

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.

Australia’s Future ASW Frigates: Warfare Down Under

As Asia-Pacific nations invest in submarines, serious regional players also need to invest in anti-submarine capabilities. Aircraft like the P-8A Poseidon are great, but nothing really replaces dedicated and capable ASW ships. Their opponents’ anti-ship missiles are also experiencing a jump in capability, so a secondary air defense role isn’t optional. Australia’s 2 remaining FFG-7 Adelaide-class frigates have finished an expensive and somewhat rickety systems upgrade, but they fall short of what’s needed, and won’t last all that much longer. The Adelaide-class will soon be succeeded by 3 new Hobart-class AWD. The RAN’s 8 ANZAC-class frigates are receiving much smoother ASMD air defense upgrades that will make them quite useful, but their service life will begin ebbing around 2024. Hence Australia’s SEA 5000 Future Frigate program, which may receive an early push from issues with Australia’s naval industrial base…

Naval Swiss Army Knife: MK 41 Vertical Missile Launch Systems (VLS)

The naval MK 41 Vertical Launching System (VLS) hides missiles below decks in vertical slots, with key electronics and venting systems built in. A deck and hatch assembly at the top of the module protects the missile canisters from the elements, and from other hazards during storage. Once the firing sequence begins, the hatches open to permit missile launches of various types. It is also being adapted for land use, as part of the USA’s plan to forward-deploy ballistic missile defense in allied countries.

The Mk.41 is the most widely-used naval VLS in the world, in service with the US Navy and with many countries outside the United States. Lockheed Martin is the system’s prime contractor, with components and canisters provided by BAE Systems Land & Armaments. In September 2011, however, the US Navy assumed the final integrator role.

Korea’s New Coastal Frigates: the FFX Incheon Class

South Korea currently owns some of the world’s best and most advanced shipyards. That civilian strength is beginning to create military leverage, and recent years have seen the ROK take several steps toward fielding a true open-ocean, blue water navy. Their new KDX-II destroyers, KDX-III AEGIS destroyers, LPX amphibious assault ships, and KSS-I/KSS-II (U209/U214) submarines will give the nation more clout on the international stage, but what about the home front? North Korea’s gunboats have launched surprise attacks on the ROK Navy twice in the last decade, while its submarines continue to insert commandos in South Korean territory, and committed acts of war by sinking ROKN ships. To the west, Chinese fishing rights are a contentious issue that has led to the murder of a Korean Coast Guard official on the high seas.

Hence the Future Frigate Experimental (FFX) program. It aims to build upon lessons learned from ROK naval shipbuilding programs in the 1980s and 1990s, and replace 37 existing ships with a modern class of upgunned inshore patrol frigates. A contract to build the lead FFX frigate Incheon was issued in December 2008, and South Korea continues to work to define the program, including the forthcoming Batch II design.

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.

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

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.
