India’s Multi-billion Dollar Scorpene Sub Contract

Scorpene cutaway

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 overall 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 beyond India.

Brazil & France in Deal for SSKs, SSN

Brazil’s submarines are seen as a key part of the country’s new national armaments and defense strategy, which was released on Dec 18/08. It places a higher priority on protection of Brazil’s offshore energy reserves, and sees submarines as key players in that effort. The experience of the 1982 Falklands War, in which Argentina’s entire fleet was kept in port by Britain’s nuclear fast attack boat HMS Conqueror, is often cited as instructive.

In 2008, Brazil and France signed an agreement to build 4 diesel-electric submarines (SSK), and provide assistance in developing and fielding the non-nuclear parts of 1 nuclear fast attack submarine (SSN). Key specifics, such as the presence or absence of SSK Air Independent Propulsion technologies, have yet to be made public, but the terms of the agreement leave the possibility open. Reports regarding the submarine deal’s value have varied, but the budget is now set at almost EUR 7 billion. Financing now appears to be in place, and recent releases explain the budgets, the timing, and some of the key players in Brazil’s Prosub program.

Airfields Afloat: The USA’s New Gerald Ford Class Super-Carriers

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.

LCAC Hovercraft: US Navy’s Champion Schleppers Get SLEPped

LCAC versatility

The US military calls them Landing Craft, Air Cushion (LCAC). They’re high-speed, fully amphibious hovercraft capable of carrying a 60-ton payload (75 tons in overload) over water and land at speeds in excess of 40 knots and a nominal range of up to 200 nautical miles. Carrying equipment, troops, and/or supplies, the LCAC launches from inside the well deck of an amphibious warship, then travels the waves at high speed, runs right through the surf zone near the beach, and stops at a suitable place on land. Its cargo walks or rolls off. The LCAC returns to the surf to pick up more. Rinse. Agitate. Repeat.

LCAC, ashore

A total of 91 LCACs were built between 1984-2001, and their design itself dates back to the 1970s. They require regular maintenance, refurbishment, upgrades, and even life extension programs to keep them operational into the future. This free-to-view Spotlight article will covers the program from 2005 forward, tracking contracts and key events.

CVN-72 Carrier RCOH: Shall not Perish

Somewhere, over
the rainbow…

Nuclear reactors save a lot of diesel fuel on huge ships like aircraft carriers, but there’s a catch. Mid-way through the ship’s 50-year life, the nuclear reactor needs to be refueled. The resulting “Refueling and Complex OverHaul” (RCOH) is a long, complex, potentially hazardous, and very expensive process, which also includes widespread upgrades throughout the ship. Anyone who has ever done home renovations knows that the opportunity to make upgrades can be nearly irresistible in these situations. In truth, this stage in the carrier’s life is an excellent time for that kind of work.

The USS Abraham Lincoln [CVN 72] was built by Northrop Grumman’s Newport News sector. Commissioned on Nov 11/1989 and homeported in Everett, WA, CVN 72 is expected to remain in service until 2039. As it approaches its mid-life stage, however, its mid-life upgrade and reactor refueling likewise approaches. Its counterpart USS Carl Vinson [CVN 70] completed its RCOH at the end of 2009, and USS Theodore Roosevelt’s [CVN 71] is underway. CVN 72 will become the 6th American carrier to undergo this procedure.

Boldly Gone: The End for the USS Enterprise

The all-nuclear
Task Force One, 1964

There was a time when USS Enterprise was the most famous ship in the world. It still is, but these days, most people think of the fictional starship rather than the world’s first nuclear-powered carrier. The real USS Enterprise was commissioned in 1961, which means that its long career of service must soon draw to a close. In April 2008, a $453.3 million contract covered the ship’s Extended Drydocking Selected Restricted Availability for maintenance and upgrades – but reached over $660 million before all was said and done, and took 2 years.

That kept “the Big E” going for a couple more years, but it could only delay the inevitable. 2012 saw the ship’s last mission come to an end, and by 2014, USS Enterprise is scheduled to fade into history, to be replaced by the first ship [CVN 78] of the Gerald R. Ford Class. This time, there will be no reruns or syndication deals. When the end comes, plans and facilities for permanently decommissioning the ship and dealing with its A2W nuclear reactors will need to be ready.

Australia’s Next-Generation Submarines

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. This FOCUS article covers Australia’s options, decisions, and plans, as their future submarine program slowly gets underway.

India’s Nuclear Submarine Projects

SSN Akula Class

According to GlobalSecurity.org, India’s ATV (advanced technology vessel) program to build a nuclear-powered submarine began in 1974, and became a serious effort in 1985. The Federation of American Scientists’ December 1996 document “The Indian Strategic Nuclear Submarine Project: An Open Literature Analysis” remains one of the best single open sources on India’s program. Unfortunately, it was compiled over a decade ago and has become rather dated. That project has continued, and this DID Spotlight article continues to collect open source information on the ATV program.

More and more sources were claiming that a rented Russian Akula class boat would be operational as a training vessel by 2009. The concept was correct, but the date was not. A deadly accident during K-152 Nerpa’s sea trials delayed that project, and further complications pushed its hand-over date to 2012. As efforts to move the Nerpa into service continue, India has finally launched its indigenous nuclear sub Arihant, to begin sea trials and testing.

The US Navy’s Nuclear Propulsion Contracts

Basic Nuclear Propulsion
(click to expand)

This DII Spotlight article covers American nuclear propulsion industrial base contracts since the beginning of FY 2006. The USA has had an all-nuclear submarine fleet for over 50 years, a policy that dates back to the visionary Admiral Hyman Rickover. On the surface, America’s aircraft carriers became an all-nuclear fleet with the retirement of the USS Kitty Hawk [CV 63], and FY 2008-09 spending legislation pushed the US Navy to use nuclear power in its future CG (X) cruisers and new amphibious ship classes. At present, however, carriers are the only nuclear-powered American surface ships on the drawing board.

The civilian nuclear sector has seen major advances over the last 2 decades, and so has the military sector. The commitment to a nuclear fleet includes funding for those technical advances, as well as work to maintain both the reactors on board American ships, and the industrial base that supports them.

USS Theodore Roosevelt Headed Into Mid-Life Overhaul

CVN-71, Indian Ocean

The USS Theodore Roosevelt [CVN 71] was built by Northrop Grumman’s Newport News sector. Commissioned on Oct 25/86, CVN 71 is expected to remain in service until 2036. As it approaches its mid-life stage, however, the wear begins to show. Instead of putting a ramp on its flight deck, buying it a nice red car, and pairing it with much younger ships, the US government has begun preparing for the refueling and complex overhaul (RCOH) of the carrier and its reactor plants.

The USS Theodore Roosevelt arrived at the Newport News shipyard in August 2009 to begin its RCOH, and Northrop Grumman has valued the planning phase alone at $558 million. So what exactly is a RCOH, and how expensive is it likely to get before all is said and done?
