The Royal Navy's future carrier, HMS Queen Elizabeth
, saw its propulsion system powered up
for the first time at the back-end of last week. Powered by two Rolls-Royce Marine 36MW MT30 gas turbine alternators and four diesel engines, the total power reaches approximately 110 megawatts. The carrier will be equipped with F-35B fighters
, with a joint US-UK team testing the jet on a replica of the Elizabeth-class carrier's ski-jump last week
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.

Belgium's fleet of NH90
tactical transport helicopters has achieved Initial Operating Capability, following a procurement contract in 2007. The fourth and final NH90 helicopter was handed to the Belgian military last November
. The country has also ordered four naval variants of the helicopter. France announced last week that it intends to modify
some of its NH90s for Special Forces use, including installing electro-optic/infrared (EO/IR) systems and data links.
NH90: TTH & NFH
The NH90 emerged from a requirement that created a NATO helicopter development and procurement agency in 1992 and, at almost the same time, established NH Industries (62.5% EADS Eurocopter, 32.5% AgustaWestland, and 5% Stork Fokker) to build the hardware. The NATO Frigate Helicopter was originally developed to fit between light naval helicopters like AW’s Lynx or Eurocopter’s Panther, and medium-heavy naval helicopters like the European EH101. A quick look at the NFH design showed definite possibilities as a troop transport helicopter, however, and soon the NH90 project had branched into 2 versions, with more to follow.
The nearest equivalent would be Sikorsky’s popular H-60 Seahawk/ Black Hawk family, but the NH90 includes a set of innovative features that give it some distinguishing selling points. Its combination of corrosion-proofing, lower maintenance, greater troop or load capacity, and the flexibility offered by that rear ramp have made the NH90 a popular global competitor.
As many business people discover the hard way, however, success can be almost as dangerous as failure. NH Industries has had great difficulty ramping up production fast enough to meet promised deliveries, which has left several buyers upset. Certification and acceptance have also been slow, with very few NH90s in service over a decade after the first contracts were signed. Booked orders have actually been sliding backward over the last year, and currently stand at around 500 machines, on behalf of 14 nations.

Huntington Ingalls was awarded $4.3 billion
through two contracts on Friday, with the shipyard handed a $3.35 billion detail design and construction contract for CVN-79, a member of the Navy's new class of super-carriers
. The subsidiary of Newport News Shipyard also received a $941.2 million modification to a previously awarded contract in support of CVN-79, also known as the USS John F. Kennedy. The new class of carriers was recently criticized
for being too expensive, with Huntington Ingalls the sole manufacturer of nuclear-powered aircraft carriers. The John F. Kennedy is the second ship in the class, under construction with a cost-cap of $11.5 billion
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 Air Force is adding one HC-130J to its original 2012 contract
, at a cost of $72.7 million
RAAF C-130J-30, flares
The C-130 Hercules remains one of the longest-running aerospace manufacturing programs of all time. Since 1956, over 40 models and variants have served as the tactical airlift backbone for over 50 nations. The C-130J looks similar, but the number of changes almost makes it a new aircraft. Those changes also created issues; the program has been the focus of a great deal of controversy in America – and even of a full program restructuring in 2006. Some early concerns from critics were put to rest when the C-130J demonstrated in-theater performance on the front lines that was a major improvement over its C-130E/H predecessors. A valid follow-on question might be: does it break the bottleneck limitations that have hobbled a number of multi-billion dollar US Army vehicle development programs?
C-130J customers now include Australia, Britain, Canada, Denmark, India, Israel, Iraq, Italy, Kuwait, Norway, Oman, Qatar, Saudi Arabia, South Korea, Tunisia, and the United States. American C-130J purchases are taking place under both annual budgets and supplemental wartime funding, in order to replace tactical transport and special forces fleets that are flying old aircraft and in dire need of major repairs. This DID FOCUS Article describes the C-130J, examines the bottleneck issue, covers global developments for the C-130J program, and looks at present and emerging competitors.

Latest updates[?]: BMD capability as a future upgrade?
The US military’s long run of unquestioned air superiority has led to shortcuts in mobile land-based air defenses, and the US Marines are no exception. A December 2005 release from Sen. Schumer’s office [D-NY] said that:
“Current radar performance does not meet operational forces requirements… consequences could potentially allow opposing forces to gain air and ground superiority in future operational areas.”
One of the programs in the works to address this gap is the AN/TPS-80 G/ATOR mobile radar system. It’s actually the result of fusing 2 programs: the Multi-Role Radar System (MRRS), and Ground Weapons Locator Radar (GWLR) requirements. When the last G/ATOR software upgrade becomes operational, it will replace and consolidate numerous legacy radars, including the AN/TPS-63 air surveillance, AN/MPQ-62 force control, AN/TPS-73 air traffic control, AN/UPS-3 air defense, and AN/TPQ-36/37 artillery tracking & locating radar systems.
