USA’s Nimitz Class &
UK’s Invincible Class
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.
Nimitz Class cutaway
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.

The Royal Navy's future Queen Elizabeth-class carrier
looks set to feature unmanned boats, with BAE Systems and ASV demonstrating
an Unmanned Surface Vehicle (USV) boat near Portsmouth Naval Base. The system is purportedly capable of allowing the boats to operate for up to twelve hours at a time in a reconnaissance and surveillance capacity. The technology - designed to be retrofitted onto Pacific 24 Rigid Inflatable Boats - could also equip manned RIBs deployed on Type 23 Frigates
and Type 45 destroyers
RN CVF Concept
Britain’s 1998 Strategic Defence Review (SDR) announced a big leap forward for the Royal Navy: plans to replace the current set of 3 Invincible Class 22,000t escort carriers with 2 larger, more capable Future Aircraft Carrier (CVF) ships that could operate a more powerful force. These new carriers would be joint-service platforms, operating F-35B aircraft, plus helicopters and UAVs from all 3 services. Roles could include ISR (Intelligence, Surveillance & Reconnaissance), force projection and logistics support, close air support, anti-submarine/ anti-surface naval warfare, and land attack.
The scale of the CVF effort relative to Britain’s past experiences means that the program structure is rather complex. It has passed through several stages already, and is being run and conducted within an industrial alliance framework. There is also a parallel international framework, involving cooperation with France on its PA2 carrier as a derivative of the CVF design. This DID FOCUS article covers that structure and framework, ongoing developments, and the ships themselves as they move slowly through construction, and eventual fielding.

The final Zumwalt-class
destroyer undergoing construction by General Dynamics Bath Ironworks - the future USS Lyndon B. Johnson (DDG 1002) - is facing the chop
by an independent team of Pentagon cost assessors, with the third-in-class vessel already under construction. Estimated to cost $3.5 billion, the destroyer was originally supposed to be the third of 32 destroyers, with numbers revised down to first eight then three ships. Cancelling the third ship would effectively cancel the most cost-efficient of the three, as the line becomes more streamlined through each iteration of construction.
67% of the fleet
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.
True, or False?
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.

Algeria is ordering an additional fourteen Su-30MKI multirole fighters from Russia to supplement the 44 already in service with the Algerian Air Force. Algeria is an important export customer
for the Russian defense industry, with the North African country ordering a significant number of attack and transport helicopters last June
. The Indian Air Force
also operates the Su-30MKI, with the IAF suffering a high crash rate among its fleet in recent months
. This latest deal is thought to value approximately $420 million, with deliveries expected between 2016 and 2017.
A February 2006 report noted that a $4 billion arms sale was brewing between Algeria and Russia involving fighter aircraft, tanks, and air defense systems, with the possibility of additional equipment. Those options came through the following month, as a high-level Russian delegation in Algeria closed up to $7.5 billion worth of arms contracts. The Algerian package remains post-Soviet Russia’s largest single arms deal. As an instructive comparison, annual Russian weapons export orders from all customers were just $5-6 billion per year in 2004 and 2005.
Reuters South Africa quoted Rosoboronexport chief Sergei Chemezov as saying that “Practically all types of arms which we have are included, anti-missile systems, aviation, sea and land technology.” The actual contents of that deal were murky, though DID offers triangulation among several sources to help sort out the confusion. A number of these deals have evolved over time, and other public-source information has helped to sharpen the picture a bit. The subsequent crash of Algeria’s MiG-29 deal, and its ripple effects, are also discussed.

The Royal Australian Navy's second Canberra-class
Landing Helicopter Dock (LHD), the Adelaide, has completed
sea trials off the country's south east coast. The trials began in August
and are the final series of tests ahead of an anticipated entry into service in 2016. The first ship in class, the Canberra, was commissioned last November, with the two ships jointly constructed by BAE Systems and Navantia following a $2.8 billion contract awarded in October 2007.
In May of 2006 the Royal Australian Navy announced its decision to expand its naval expeditionary capabilities. HMAS Manoora and Kanimbla would be replaced with substantially larger and more capable modern designs, featuring strong air support. Navantia and Tenix offered a 27,000t Landing Helicopter Dock (LHD) design that resembled the Strategic Projection Ship (Buque de Proyeccion Estrategica) under construction for the Spanish Navy. The DCNS-Thales Australia team, meanwhile, proposed a variation of the 21,300t Mistral Class that is serving successfully with the French Navy.
Navantia’s larger design eventually won, giving the Spanish firm an A$ 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.

Northrop Grumman's naval UAV the Fire Scout
is completing endurance demonstrations, flitting about for 10 hours at a time.
MQ-8B Fire Scout
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.
