A Look at Britain's and France's Nuclear Arsenals

 The British nuclear submarine HMS Astute can carry up to 48 nuclear warheads.

For Great Britain and France, the possession of nuclear weapons is a question of national pride, but neither country wants to eliminate its deterrent in the future. For cost reasons alone, though, the countries' arsenals are expected to shrink in the coming years.

France and Great Britain are part of a small club of the five official nuclear powers. The French force de frappe, or deterrent, is made up of approximately 300 nuclear warheads, while the British Royal Navy has just over 160. Both have fleets of four nuclear-powered and nuclear-armed submarines, of which one is always at sea. Paris maintains four more squadrons of planes with nuclear weapons, three on the ground and one at the Charles de Gaulle aircraft carrier.

Since the end of the Cold War, both countries have considerably shrunken their arsenals. The production of weapons-grade plutonium has been stopped entirely. And Great Britain eliminated all the nuclear weaspons possessed by its army and air force.

Neither London nor Paris is playing a central role in the current debate over disarmament. France and Britain make the point that the United States and Russia must disarm themselves to the level of the two European countries before any need will arise for further negotiations.

Both Countries Look to Successor Generation, But Cuts Still Likely

Neither France nor Great Britain wants to fully give up their nuclear weapons, and both consider the round-the-clock nuclear deterrent to be indispensible. And both countries are working on the successor generation to weapons systems currently in their possession.

With fiscal budgets constrained, however, both countries are considering further limiting the scope of their nuclear arsenals. While speaking before the United Nations last September, British Prime Minister Gordon Brown said his country wanted to make due with three nuclear submarines in the future instead of four. The French government recently offered to create a joint sea-based nuclear deterrent by sharing submarine patrols. Experts see the proposal as a model for the future, but the idea has so far been rejected by London.

Cooperation in Europe is also complicated by the fact that the British nuclear program has long been deeply interwoven with that of the United States. The Trident II missiles that are deployed with British submarines are stored in a common pool of missiles of the same type at Kings Bay, Georgia.

Britain and France are the only countries in the European Union to possess their own nuclear weapons. As part of NATO, however, around 200 American short-range nuclear warheads are stored in Europe, including an estimated 20 weapons in Germany.

A look at the two European nuclear powers in facts:

France :

300 nuclear warheads

4 Le Triomphant class submarines, stationed at Ile Longue in Bretagne. Each submarine can carry up to 16 M45 missiles, which can in turn be armed with six war heads each.

The newest submarine, which goes into service in 2010, is armed with M51 long-range missiles with a range of 9,000 kilometers (5,592 miles).

3 squadrons of planes, each with 20 Mirage 2000N, stationed in Istres, Luxeil-Les-Bains and Saint Dizier. They are armed with air-to-surface missiles (ASMP) with a range of up to 300 kilometers.

20 Super Étendard fighter-bombers are stationed on the aircraft carrier Charles de Gaulle.

Great Britain :

160 nuclear warheads

4 Vanguard-class submarines, stationed at a base in Faslane, Scotland. Each can carry up to 16 Trident missiles (with a range of 10,000 kilometers) with a maximum of 48 war heads on board.

16 underground bunkers for storing nuclear weapons in Coulport near Faslane -- development and construction of the warheads through the Atomic Weapons Establishment (AWE) in Aldermaston, England.

After long delay, India moves to expand strategic Karwar naval base

NEW DELHI: India is finally going in for a major expansion of its newest naval base at Karwar in coastal Karnataka, which provides it "strategic depth" on the western seaboard and will house aircraft carriers and nuclear submarines in the future.

This comes after a long delay since the ambitious `Project Seabird' to build the futuristic Karwar naval base was first approved by the government way back in 1985 at an initial cost of Rs 350 crore.

Budgetary constraints derailed the project for a decade before a truncated Phase-I was approved in 1995, with the work finally commencing in 1999 with a Rs 2,500 crore fund allocation.

"Phase-I is now fully complete. We have 10 warships based there. Now, the detailed project report for Phase-II is in the final stages. After approval by the Cabinet Committee on Security, construction will begin next year,'' Navy chief Admiral Nirmal Verma told TOI.

Navy will be able to berth 25 to 30 big warships at Karwar after Phase-II gets over by 2017, he added. The base will also house a wide variety of smaller ships, including 10 of the 80 fast-interceptor craft of Sagar Prahari Bal, the specialised force being raised for coastal security after the 26/11 terror attacks on Mumbai.

Pakistan has already built its new Gwadar deep-sea port with China's help in Baluchistan, which will help the two countries gain a crucial foothold in the Gulf region.

Admiral Verma, on his part, said, "Our maritime perspective plan takes into account the threats we may face in the future.''

With Navy keen to operate two carrier battle groups around 44,570-tonne Admiral Gorshkov and 40,000-tonne indigenous aircraft carrier by 2014-2015, the Karwar base is critical for its blue-water operations in Indian Ocean and beyond. The eventual aim is to make it capable of handling as many as 50 frontline warships.

The 130-warship Navy also currently has three destroyers, six guided-missile frigates, six submarines, two fleet tankers, four anti-submarine corvettes, six survey vessels, six fast-attack craft and a sail training ship under construction. Moreover, it's on course to order another four destroyers and seven frigates, among other warships.

Karwar, spread over 4,480 hectares on a 26-km stretch along the coastline at present, is being developed into a major naval base after Mumbai and Visakhapatnam for three main reasons.

Defence to overhaul Collins class submarine comms

Defence will overhaul the communications on its fleet of its Collins class submarines, replacing the existing Communications Centre (COMMCEN) and implementing a new External Communications System (ECS).

The ECS will also incorporate a High Data Rate Satellite Communications link, allowing connectivity to the Defence information environment and the Maritime Tactical Wide Area Network.

The satellite communications system will operate in the Super High Frequency band and allow the submarines to exchange data at rates more than 25 times faster.

The replacement of the Collins Class ECS will provide Australia’s submarine fleet with a modern communications architecture that will meet the future operational needs of the submarines.

According to Defence spokesperson, the project is part of the Communication and Electronic Warfare Improvement Program aimed at improving the electronic warfare and external communications systems fitted to the Collins class through the acquisition of a high data rate satellite communications capability, replacement of the existing communications centre and enhancements to the fitted electronic warfare capability.

The project should deliver a capability for the submarines to use Internet Protocol-based communications and contribute to the Defence’s vision of a network-enabled force, the spokesperson said.

“The current Communications Centre was designed and built in the 1980s and it is becoming increasingly difficult to sustain the capability,” the spokesperson said. “Not only are the electronic components obsolete with replacement components long out of production, the architecture of the COMCEN does not allow the processing of contemporary IP-based communications.”

As part of the project, an IP-based LAN environment will be installed through the whole submarine, the spokesperson said.

“In order to make the transition from what is essentially a TELEX [telephone exchange] room into what will become the hub of a network where operators can interact directly with their colleagues requires that the communications capability extend beyond the COMCEN and into the submarine itself,” the spokesperson said.

Russia to build submarine-detecting satellite

Russia could build a satellite for the detection and tracking of submarines from space, a defense industry spokesman said on Thursday, according to RIA Novosti.

Vladimir Boldyrev, of the Kosmonit science and technology center, said the group had developed a space satellite module that could carry out remote sensing of the sea and "detect submerged submarines."

"Hopefully, it will be tested in space as early as 2011," he said, adding that work on the module started over a decade ago.

He offered no indication as to when the new satellite would enter service with the Russian Armed Forces.


Boldyrev added that the dual-use module would be used for both defense and civilian purposes, in particular, providing meteorological data. (RIA Novosti)

Melbourne defense firm reels in Navy submarine software deal

Melbourne-based Modus Operandi Inc. said Monday it has received a $600,000 deal to provide submarine intelligence analysis software for the U.S. Navy.

The small defense contractor has now won nearly a half dozen contracts since late 2009, cumulatively worth more than $3.3 million.

Its latest was a Small Business Innovation Research contract from the Naval Sea Systems Command at Washington Navy Yard. The deal is sponsored by the Program Executive Office for Submarines.

Terms of the project call for Modus Operandi to design software technology that will process and feed intelligence information from various sources into an integrated database for submarine commanders, the company said.

The new system "will provide submarine control room personnel, and ultimately commanders, with a vastly improved common operating picture allowing them to perform more mission types with greater confidence," Modus Operandi chief scientist Richard Hull said in a written statement.
