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 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.

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.

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.

AMDR: Raytheon Wins Dual-Band Radar, Pending Protest

The US Navy’s Dual-Band Radar that equips its forthcoming Gerald R. Ford class super-carriers replaces several different radars with a single back-end. Merging Raytheon’s X-band SPY-3 with Lockheed Martin’s S-band VSR allows fewer radar antennas, faster response time, faster adaptation to new situations, one-step upgrades to the radar suite as a whole, and better utilization of the ship’s power, electronics, and bandwidth.

Rather than using that existing Dual-Band Radar design in new surface combatant ships, however, the “Air and Missile Defense Radar” (AMDR) aims to fulfill DG-51 Flight III destroyer needs through a new competition for a similar dual-band radar. It could end up being a big deal for the winning radar manufacturer, and for the fleet. If, and only if, the technical, power, and weight challenges can be mastered at an affordable price.

Sons of Sa’ar? Israel’s Next Generation Frigates

The 1,227t/ 1,350 ton Sa’ar 5 Eilat Class corvettes were built by Northrop Grumman in the 1990s for about $260 million each. It’s a decent performer in a number of roles, from air defense to anti-submarine work, to coastal patrol and special forces support. In 2006, the Israelis went looking for a next-generation vessel with better high-end capabilities. Six years later, Israel had nothing to show for its search. In the meantime, massive natural gas deposits have been discovered within Israel’s coastal waters, adding considerable urgency to their search.

The USA is Israel’s logical supplier, but given Israel’s size and cost requirements, the only American option was the Littoral Combat Ship. Israel pursued that option for several years, conducting studies and trying to get a better sense of feasibility and costs. Their approach would have been very different from the American Freedom Class LCS, removing the swappable “mission modules” and replacing them with a fixed and fully capable set of air defense, anti-ship, and anti-submarine weapons. In the end, however, the project was deemed to be unaffordable. Instead, Israel began negotiating with Germany, and reports now include discussions involving both South Korea, and a local shipyard.

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.

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.

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.

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.
