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

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.

NAVAIR has been slamming missiles
into the side of its KC-46 tankers as part of Naval Air Warfare Center Weapons Division survivability testing at the Weapons Survivability Laboratory
. The tests used - among other sensors - ten high-speed cameras to capture the impact of the test missiles, themselves specifically designed to inflict maximum possible damage to the aircraft. The Air Force intends to buy 179 of the tankers to replace approximately a third of the current tanker fleet, which consists principally of KC-135 Stratotankers.
KC-135: Old as the hills…
DID’s FOCUS articles cover major weapons acquisition programs – and no program is more important to the USAF than its aerial tanker fleet renewal. In January 2007, the big question was whether there would be a competition for the USA’s KC-X proposal, covering 175 production aircraft and 4 test platforms. The total cost is now estimated at $52 billion, but America’s aerial tanker fleet demands new planes to replace its KC-135s, whose most recent new delivery was in 1965. Otherwise, unpredictable age or fatigue issues, like the ones that grounded its F-15A-D fighters in 2008, could ground its aerial tankers – and with them, a substantial slice of the USA’s total airpower.
KC-Y and KC-Z buys are supposed to follow in subsequent decades, in order to replace 530 (195 active; ANG 251; Reserve 84) active tankers, as well as the USAF’s 59 heavy KC-10 tankers that were delivered from 1979-1987. Then again, fiscal and demographic realities may mean that the 179 plane KC-X buy is “it” for the USAF. Either way, the KC-X stakes were huge for all concerned.
In the end, it was Team Boeing’s KC-767 NexGen/ KC-46A (767 derivative) vs. EADS North America’s KC-45A (Airbus KC-30/A330-200 derivative), both within the Pentagon and in the halls of Congress. The financial and employment stakes guaranteed a huge political fight no matter which side won. After Airbus won in 2008, that fight ended up sinking and restarting the entire program. Three years later, Boeing won the recompete. Now, they have to deliver their KC-46A.

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 Navy's EA-18G Growlers could use their electronic warfare capabilities to locate insurgents
for targeting through the triangulation of intercepted signals, with three aircraft working as a team. However, before this can happen, the aircraft need new, faster data links in order to corroborate intercepts and locate the source of the tracked signals. A USN study
recently argued that the Navy needs more of the aircraft to meet future operational demand. A Pentagon Electronic Warfare Committee was also stood up in March
, highlighting the continued relevance of these non-stealthy workhorses despite uncertainty over the aircraft's future production line
EA-18G at Pax
The USA’s electronic attack fighters are a unique, overworked, and nearly obsolete capability. With the retirement of the US Air Force’s long-range EF-111 Raven “Spark ‘Vark,” the aging 4-seat EA-6B Prowlers became the USA’s only remaining fighter for radar jamming, communications jamming and information operations like signals interception . Despite their age and performance limits, they’ve been predictably busy on the front lines, used for everything from escorting strike aircraft against heavily defended targets, to disrupting enemy IED land mine attacks by jamming all radio signals in an area.
All airframes have lifespan limits, however, and the EA-6B is no exception. The USA’s new electronic warfare aircraft will be based on Boeing’s 2-seat F/A-18F Super Hornet multi-role fighter, and has 90% commonality with its counterpart. That will give it decent self-defense capabilities, as well as electronic attack potential. At present, however, the EA-18G is slated to be the only dedicated electronic warfare aircraft in the USA’s future force. Since the USA is currently the only western country with such aircraft, the US Navy’s EA-18G fleet would become the sole source of tactical jamming support for NATO and allied air forces as well.
DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This article describes the EA-18G aircraft and its key systems, outlining the program, and keeping track of ongoing developments, contracts, etc. that affect the program.

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.
