TAURUS 2009 BEATS ROYAL NAVY OVERSTRETCH
Taliban in sectors of southern Afghanistan, the British fleet has still, somehow, launched a milestone deployment. Amphibious
warfare ships and frigates departed Plymouth last month (Feb), the culmination of 18 months planning, on the two-phase,
Taurus 09, which will not conclude until August, after more than 20,000 miles of steaming. Including key training in amphibious warfare, Anti-Submarine Warfare (ASW) and even jungle warfare, the Taurus agenda will also aim to support active Maritime
Security Operations - including anti-piracy and counter-terrorism beyond Suez - as well as Defence Diplomacy and reinforcing
long-standing strategic partnerships. Spearheaded by the UK amphibious warfare flagship, and LPD, HMS Bulwark, plus assault carrier HMS Ocean, the task group numbers ten major surface vessels, including the French frigate FS Dupleix and American destroyer USS Mitscher, plus a pair of unnamed RN Trafalgar Class hunter-killer submarines. In an interview aboard Bulwark
the day before ships deployed, the RN’s Commander-in-Chief Fleet, Admiral Sir Mark Stanhope, reflected that it was a large commitment “bearing in mind the current stretch around the Navy.” Admiral Stanhope, who is to be First Sea Lord from summer
2009, explained why Taurus was worth the effort: “The reason for doing this is that, while Afghanistan is today’s focus, we have
to be prepared for the future and the uncertainties that entails.” Admiral Stanhope added: “I have to ensure there is enough fundamental capability in the Navy to deliver, if required, an amphibious force.” He also gave the opinion that for a navy to be considered premiere league it must fulfil certain requirements and one of them is the ability to deploy, as well as command and control, such a task group at a long distance for some months. Clearly, despite declining ship numbers, and the heavy commitment
to Afghanistan of marines, sailors and aviators, the British fleet is determined to demonstrate it is still in the top rank. Admiral
Stanhope observed: “The only way we can be sure that we can deliver that within a particular time-scale is to do it.” He admitted
that putting together the task group had by no means been easy. “It has been a challenge,” said the admiral. “The focus of our business is quite rightly Afghanistan and Iraq and, in a purely naval sense, operations in the Gulf and also against piracy, not forgetting other draws on maritime forces elsewhere in the world.” As set out by the current First Sea Lord, Admiral Sir Jonathon
Band, in his ‘Flag Hoist’ to the fleet, a high priority in 2009 is the preservation and development of “the minimum ‘seed corn’ warfighting capability” in ASW and littoral manoeuvre operations. Taurus 09 will tick the box for both. Admiral Stanhope observed:
“It is a question of time fade - if you don’t do these things regularly enough then seed corn capability can be reduced.” To that end,
in addition to 40 Commando Royal Marines embarking in task group ships for exercises, there are Merlin ASW helicopters
deployed with Ocean. Taurus 09 frigate HMS Somerset is one of the most modern sub hunters in the RN. There is no UK destroyer assigned to the task group. British destroyer numbers are currently at an all-time low, with three Type 42s taken out of front line
service at the end of last year, leaving just five and with only one replacement ship (Daring) close to entering service. However, Admiral Stanhope made it clear assignment of a French frigate and an American destroyer to Taurus was not a case of “back-filling”
for lack of a British destroyer. CINC Fleet stressed that the deployment was very much about multinational command and control.
He considered that, ideally, he would have liked to see a UK destroyer in the force, but it was not possible. Admiral Stanhope conceded: “We are stretched in terms of my ability to cover all of current tasks.” Commander UK Amphibious Task Group,
Commodore Peter Hudson, is the at-sea commander of Taurus 09. Last year he commanded the key coalition Combined Task
Group 152 (CTF-152) in the central Gulf. He said his time in Bahrain had given him insight into the level of connectivity needed
to run a task group. With his embarked staff officers - particularly a new intelligence cell - Cdre Hudson will keep an eye on the emerging situation as the deployment develops. This will particularly apply East of Suez when operating close to the anti-piracy
CTF-151, when it is intended support will be provided for its ongoing operations. Deputy Brigade Commander, 3 Commando
Brigade Royal Marines, Colonel Martin L. Smith who has been on deployment to Afghanistan, is in charge of the Royal Marines element of Taurus. He welcomed the opportunity for Britain’s sea soldiers to get back to their traditional skills after several years mainly occupied in fighting the Taliban in a landlocked country. Colonel Smith said: “Clearly, Afghanistan is very challenging
but there are levels of complexity that you obviously cannot access on land. We don’t know what is going to hit us next, so it is essential to maintain amphibious capability. It is a very perishable skill.” The Ministry of Defence has stated that, at its height
more than 3,000 UK military personnel will be involved. A UK MoD briefing document outlined how Taurus breaks down:
‘Phase One will involve amphibious training with nations in the Mediterranean, culminating in a series of amphibious
landings in Turkey as part of a joint and combined exercise. Phase Two will see part of the Task Group deploy through the
Suez Canal, culminating in a multinational training package in the primary jungles of Brunei. Riverine training will also be
conducted with the Bangladeshi Navy, the first such interaction in more than a decade.’ As ever the British fleet is seeking
to squeeze as much as possible out of scarce resources as it can, to maximise the presence of the White Ensign on the high seas.

THE INTERVIEW
You have only fairly recently taken over as Chief of Naval Staff, at a time when the Pakistan Navy is very much in transition. What are your over-riding objectives during your time in office?
"I hope that I will be able to complete everything that I have started, but I realise that is not always possible. I hope to make up the shortages in surface ships, to induct a new batch of P-3C Orion maritime patrol aircraft, and to induct the weapons and sensors that we are looking for. Some of them have been ordered, while the others are in the process of being ordered. I would also like to see before I leave the helm as CNS, a new submarine type agreed and to hopefully start construction of the first one of those. It is a big canvas, and I hope that I will be able to have fairly substantial input in all these areas before I leave."
With the present government more receptive to the Navy's needs, does the future now look brighter for the PN?
"As I see it, the future is bright. I know this to be true because of our future plans. We are getting full support from the government in fulfiling our core requirements."
Earlier this year the PN decommissioned its four Daphne/Hangor Class submarines. Do you not think this leaves a capability gap?
"Yes, it has left a capabilities and a numbers gap, but, as I indicated earlier, we are very actively pursuing the selection of the next generation of submarine which will hopefully be constructed within the country."
Can you reveal anything about types that you are looking at?
"It would be premature to say at this moment in time, but our position will clear up in a few months' time when we should have arrived at a decision."
There is speculation about new corvettes for the PN; can you expand on this?
"Corvettes are a requirement of the PN, in the sense that we believe larger platforms can be deployed, and should be deployed, for the more complex tasks. The lesser tasks can be carried out by the corvettes because they are smaller, plus they are relatively easier, and cheaper, to operate. So this is the philosophy that we are going by, and hopefully, in due course, although it may not happen quickly, we will select a new type of corvette that is suitable to our requirements. We will also construct it indigenously, through a transfer of technology."
Currently, the F-22P and the ex-Greek Elli Class frigates are eagerly awaited by your Navy. What new capabilities, do you expect them to bring to your force?
"More important than new capabilities is the numbers crunch that we are facing at the present. The six Type 21s that we have are not sufficient for all our training and operational requirements. As you know, our operational requirements have been enhanced by our participation in the Coalition Maritime Campaign Plan, and we are contributing one ship with an embarked helicopter to this operation, and this has put a strain on our limited numbers. So the Elli Class ships will, in the first instance, alleviate some of this pressure that we have as far as fielding a ship for CMCP is concerned. Hopefully with the commissioning into service of these ships, we might be able to enhance our participation with the CMCP."
A force within the PN that is still quite young, and does not have a very high profile, is the PN Marines. What does the future hold for this force?
"The marines are a very important component of the PN. They have a role, a task, and a mission, in the overall framework of the PN and Pakistan. We are at present in the process of equipping this force with the better platforms and better weapons that they need. In this context, we have acquired four hovercraft which are already with us and operating. We have smaller, faster boats that are required for the marines' operations, and we are going to enhance and improve the mobility and firepower of the marines to suitably match their role and tasks in the seaward defence of the South Eastern Coast."
The PN was recently in command of the Coalition counter-terrorist force Combined Task Force 150 (CTF-150) and, building on that experience, are there any areas where you think things could be done differently?
"We are the first non-NATO navy to have assumed command of this force and, hopefully, there will be more slots offered to the PN. I think that it has been a great experience for our ships' crews, and for the officers and men who were in Bahrain commanding the task force. I would also add that everyone has learned from the experience. Our Coalition partners have, I am sure, learned many things from our participation, as we have indeed from participating in the task force."
What is the most significant lesson the PN has learned from participating in CTF-150?
"There were a number of aspects of operations which were new to us. The lessons learned spanned the entire spectrum, ranging from intellectual to operational and to tactical levels. Perhaps the most important one was the realisation of our strengths and capabilities."
In June I spent some time in HMS Illustrious, the British Fleet Flagship when she was attached to CTF-150. One of the main concerns was drugs being smuggled from the Mekran Coast to Yemen and beyond. What has the PN been doing to combat this menace?
"Within the two years that we, the PN, have been participating in CTF-150 we have encountered very few cases of drug smuggling or intercepted drug smuggling, which means that, maybe, the drug smugglers are taking some other route than the one that you are suggesting. With the presence of not only Pakistani ships but also ships of other nationalities, which are part of CTF-150, if there was any large-scale movement of drugs taking place along this route, certainly they would have been intercepted, which has not been the case. Up until now we have tackled additional important tasks, in the form of combating human smuggling, and assisting the victims of that form of trafficking. The smugglers take their money and leave them in the middle of the ocean with nowhere to go. This is what we have been doing, providing assistance to these people. Most of the time they are innocent people who have been taken advantage of by the smugglers who give them hope of a better future."
Pakistan has a long and under-populated coastline that is naturally smuggler friendly. To patrol this area, doesn't the PN patrol craft flotilla need to grow beyond its current level?
"Of course, but it is the Maritime Security Agency (MSA), that needs to be beefed up, not the PN. We are examining ways in which we can boost the facilities and assets of the MSA whose remit it actually is. They need to be provided with the support that will enable them to perform their task better."
One legitimate criticism regarding smuggling that is true of all nations in the CTF-150 region, is that the various agencies of the State - police, coastguard, customs, and navy - do not always work as well together as they perhaps should or could. How is Pakistan doing in this respect?
"We have a system that is functioning and there are responsibilities that are divided. It is the MSA's responsibility to apprehend smugglers, whether they are smuggling drugs, alcohol, people or whatever, and hand them over to the police. Customs officials have a role as well, but this is the system that we have in place and follow at this point in time."
Since 1971 the role of the PN has largely been to police the EEZ and maintain Sea Lines of Communication to the Gulf. Has participation in CTF-150 changed the PN's priorities?
"Not really, but first I will correct you, if I may. It is the MSA that looks after the EEZ.
The PN of course looks after the SLOC. All of our oil and some other commodities come from the Gulf, 95 per cent of our trade is seaborne, and, as long as this state of affairs exists, we will safeguard this commercial activity. We may do things a little bit differently but the core task will remain the same."
Who does Pakistan consider to be its allies at sea?
"As far as the Global War on Terror is concerned, NATO and the US are our allies at the moment in relation to CMCP operations. However, we have a very good professional relationship with the Saudi Arabian Navy, the Omani Navy, and the United Arab Emirates Navy. These are the regional players in this area and we have a very good relationship with them."
What about the Chinese Navy?
"We have a good relationship with the People's Liberation Army Navy. We do conduct operations with them, basic ones, and that is where things stand at the moment."
Are there any wholly new capabilities that you would like to see introduced into the PN?
"That is a difficult question. I suppose we are a four-dimensional force: Surface ships; aircraft; submarines and the Special Service Group of Navy/Marines. We would naturally like to boost these four components. There are always new ways of doing this, via training, induction of new sensors, equipment, and these things have to change in line with modern trends. As for a totally new capability, the only thing that I can think of is perhaps surveillance through maritime Unmanned Air Vehicles. They may be a possibility for the future."
ALERT: The French-German Tussle In Pakistan
A nuclear submarine works on nuclear technology rather than conventional air-breathing diesel engines. Nuclear submarines operate on nuclear reactor technology, the same technology that is used to produce electricity. In conventional submarines, diesel engines were used to charge batteries for underwater running.
Nuclear submarines have numerous advantages over conventional diesel submarines such as they don’t need to surface frequently as they are independent of air. Unlike conventional submarines, power generated by nuclear reactor is huge and hence, they can run at high speeds for prolonged periods and neither need refueling intervals as they can operate under water throughout their lifetime (generally 25 years). These few points of nuclear powered submarines scored over conventional diesel submarines, make them stealth weapons.
History
The idea of making a nuclear submarine first emerged around 1950 when the Cold War between the US and Soviet Union (USSR) was at zenith. Both the countries were trying technologies to build nuclear powered submarines to overcome the drawbacks of conventional ones. Both the countries knew what a lethal weapon nuclear submarines would be. The US was successful in making a headway start with launching USS Nautilus, the first nuclear powered submarine in the world, on January 21, 1952. The submarines could encircle the world for 4 months without resurfacing.
It was American Admiral Rickover who first came up with the idea of making a nuclear submarine. In July 1951, the US Congress gave a green signal to Captain Rickover to proceed with the development of nuclear submarine, at the Naval Reactors Branch of Atomic Energy Commission. The task of building the reactor was given to the Westinghouse Corporation, which is now a leader in nuclear technology.
The Soviet Union started its nuclear submarine program in the 1950s too. Its research work was done at Institute of Physics and Power Engineering at Obninsk. They began testing their models in 1956 and finally after many obstacles like radiation leaks and steam generation problems, their first nuclear powered submarine entered service in Soviet Navy on 1958.
A Brief Timeline of Nuclear Submarines
1954: 1st nuclear powered submarine, USS Nautilus was launched.
1961: Soviets claim to have fastest and largest fleet of nuclear submarines.
1963: In one of the worsts nuclear disasters, USS Thresher is lost with 129 men on board.
1986: Soviet Yankee-class submarine sinks in Atlantic Ocean with nuclear missiles on board.
1989: A Mike-class Soviet nuclear submarines sinks 500 kilometers from Norway.
2000: Russian nuclear submarine Kursk sinks.
2009: China becomes the fifth country in the world to launch rockets from a nuclear submarine.
An interesting fact is that although Russia is the country to suffer most number of nuclear submarine accidents, it produced approximately 4 to 5 nuclear submarines from each of its 4 submarine yards during the Cold War. Indeed amazing! They made about 245 nuclear submarines between the 1950s and 1997. If one adds all the nuclear submarines of world, the resulting figure still won’t be able to break the Soviet Unions figure of 425 nuclear submarines.
Since, the cost of building the nuclear submarines is very high, only a few countries have been able to make and maintain these. Countries like US, Russia, France, UK and China have operational nuclear propulsion submarines at present. However, countries like India, Brazil and Argentina have been working on similar projects

Submarines: ideal fuel cell vehicles
Fuel cells apparently make a good submarine hard to find.
Air Products of Pennsylvania this week announced it supplied a new fueling station to supply a state-of-the-art HDW 214 submarine of the Hellenic (Greek) Navy with hydrogen.
The first fueling of its kind in Greece took place this week in Skaramanga, near Athens.
Air Products supplied the integral components of the hydrogen fueling station to the submarine's designer, Howaldtswerke-Deutsche Werft GmbH (HDW), which has been experimenting with fuel cell technology for submarines since the late 1970s.
HDW's Class 212 and 214 non-nuclear submarines have been developed to use a silent operating fuel cell plant that runs on nine 34-kilowatt Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells.
Its air-independent fuel cell propulsion system provides extreme underwater endurance, diving depth and overall efficiency, HDW claims.
The fuel cells, which produce electrical energy from oxygen and hydrogen, allow the submarine to cruise under water for up to three weeks without resurfacing.
Perhaps most importantly, however, because the chemical reactions of fuel cells make no noise and produce no detectable exhaust heat, they make the submarine virtually undetectable, according to designers.
Props for fuel cells.
Conventional diesel-electric submarines typically deplete their battery power after only a few days under water. Nuclear submarines can cruise for months under water, but not everybody wants nuclear submarines, especially if there are alternatives.
Plus, says HDW, fuel cells are still quieter.
The submarine was built by Hellenic Shipyards S.A., part of the new North European shipyard ThyssenKrupp Marine Systems, which also owns HDW. Germany has four of the boats, with two more on order, and Italy has bought two.
Hellenic Shipyards is planning to build more fuel cell-powered submarines for the Hellenic Navy. And additional contracts are in place to add plug-in fuel cell retrofits to conventional driven submarines.
Air Products is a leader in hydrogen safety and engineering, and in hydrogen production and distribution, including hydrogen fueling stations. It also supplies industrial gases and associated equipment to other industries.

CB4000 Concrete Special
With a length of 42 feet and a capacity of 31 cu. yards, the Concrete Special is designed to safely and efficiently transport and unload low-slump concrete and concrete-related products. A uniquely designed gate incorporates a high compression air cylinder that provides seal-tight locking abilities so concrete cannot be forced out. An internal wash-out system with front and rear multi-head spray nozzles rinses down the belt and chain to avoid concrete build-up on vital components
CB4000 8-Axle
At 44 feet in length, the CB4000 8-Axle is equipped to haul an enormous 50 tons of payload. The belt-over-chain conveyor system is ideal for working off-road, under power wires, in tunnels, under bridges, on overpasses, steep grades and even high bank turns on race tracks. The standard features and weight distribution make the Flow Boy 8-Axle the trailer of choice in the state of Michigan
CB4000 Tri-Axle
The CB4000 Tri-Axle comes standard in two versions depending on your size and weight limitations. A 37 foot version is designed for smaller applications with a capacity of 30 cubic yards. For larger needs, a 42 foot version increases overall capacity by 10% to 33 cubic yards. Both versions feature durable double wall construction with 3 inches of R-11 insulation. A recess style tailgate with gate lock is also standard
CB4000 Tandem Axle
With an overall length of 42 feet and a payload of up to 35 tons, the CB-4000 Tandem Axle is the workhorse of the Flow Boy horizontal discharge semi-trailer family. An extra heavy duty 42 ton chain with cambered articulating flights provides a “floating pin” action that minimizes wear and tear on the entire conveyor assembly. The side sheet insulation skins and rear fenders are constructed of durable stainless steel so maintenance and rust corrosion are minimized
