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 Indian-manufactured INS Arihant nuclear SSBN
is progressing well with sea trials, according
to the Chief of the Indian Navy. Launched in 2009, the sub's reactor went critical
in August 2013 and is thought to have begun shakedown voyages from March last year. Based on the Russian Akula-1 design, the INS Arihant is India's first indigenously-manufactured nuclear sub and a critical component of the country's pursuit of a nuclear triad
capability. In related news
, the Indian MoD has restricted all future shipbuilding to domestic yards, with private shipyards having a potential workload of $3.2 billion
over the next fifteen years.
India’s submarine fleet currently consists of 16 boats: 10 Russian SSK Kilo (Sindhugosh) Class, 4 locally built SSK U209 (Shishumar) Class, a leased nuclear-powered Improved Akula Class SSN from Russia (INS Chakra), and its own INS Arihant SSBN. Most of the Kilos have been modernized, but readiness rates for India’s existing submarine fleet sits below 40%, and the U209s will have trouble lasting much beyond 2015. With Pakistan acquiring modern submarines, and Chinese submarine building exploding, expanding India’s submarine fleet became an obvious national priority.
In 2005, India confirmed that it would buy 6 Franco-Spanish Scorpene diesel submarines, with an option for 6 more and extensive technology transfer agreements. Unfortunately, 7 years after that deal was signed, “Project 75″ has yet to field a single submarine. A poor Indian procurement approach, and state-run inefficiency, are pushing the country’s entire submarine force toward an aging crisis. This DID FOCUS article covers the Scorpene deal and its structure, adds key contracts and new developments, and offers insights into the larger naval picture within and beyond India.

Japan is expected to be disappointed
that Australia will have a competitive process for choosing submarine vendors. But it won't be too competitive. Russia and North Korea have been excluded
Bridge to the future?
In its 2009 White Paper, Australia’s Department of Defence and Labor Party government looked at the progress being made in ship killing surveillance-strike complexes, and at their need to defend large sea lanes, as key drivers shaping future navies. These premises are well accepted, but the White Paper’s conclusion was a surprise. It recommended a doubling of Australia’s submarine fleet to 12 boats by 2030-2040, all of which would be a new successor design that would replace the RAN’s Collins Class submarines.
The surprise, and controversy, stem from Australia’s recent experiences. The Collins Class was designed with the strong cooperation of ThyssenKrupp’s Swedish Kockums subsidiary, and built in Australia by state-owned ASC. The class has had a checkered career, including significant difficulties with its combat systems, issues with acoustic signature and propulsion, major cost growth to A$ 5+ billion, and schedule slippage. Worse still, reports indicated that the RAN can only staff 2 of its 6 submarines. High-level attention led to a report and recommendations to improve the force, but whether they will work remains to be seen. Meanwhile, the nature of Australia’s SEA 1000 future submarine project – and its eventual cost – remain unclear, with estimated costs in the A$ 36-44 billion range. This FOCUS article covers Australia’s options, decisions, and plans, as their future submarine program slowly gets underway.
