Germany Now World's Third Largest Arms Exporter

Germany has become the world's third largest arms exporter, with many of its weapons, including this submarine, earmarked for Greece.


German arms exports more than doubled during the last five years, according to a new report, placing the country behind just the US and Russia on the list of the world's largest weaponry exporters. The opposition in Berlin wants more oversight.

When it comes to arms exports, few will be surprised that the US tops the list, with 30 percent of global expenditures on arms going to weaponry from America. Second place is likewise hardly a shocker -- 23 percent of the world's weapons originate in Russia.


Third place, though, is raising more eyebrows. According to the 2009 annual report put together by the Stockholm International Peace Research Institute (SIPRI), Germany's weapons exports have more than doubled in the last five years, to 11 percent of the global total. German submarines and tanks, the report makes clear, have gained a number of loyal customers.

Given Berlin's tentative forays into geopolitics in recent years -- against a backdrop of deep domestic skepticism about German involvement in conflicts across the globe -- it is perhaps not surprising that the opposition is up in arms at the SIPRI ranking.

Indeed, the Greens are now demanding greater parliamentary oversight for arms exports. "This report shows that we need more stringent control over and sharper criteria governing arms exports," Green leader Claudia Roth told the Kölner Stadt-Anzeiger. Parliament must finally get the right to monitor the government's weapons exports, she continued, adding that such control was commonplace elsewhere.

German submarine in Grand Harbour

German Navy submarine U-17 (Pennant number S196) slipped into Grand Harbour this morning for a courtesy visit.


The submarine was commissioned in 1973 and subsequently modernised, but vessels of this type are now being withdrawn.

The submarine has eight torpedo tubes and can carry mines.

It is seen above crossing Dockyard Creek, which is dominated by the sleek lines of the superyacht The Maltese Falcon.

Howaldtswerke-Deutsche Werft tests battery cells for submarines

Howaldtswerke-Deutsche Werft GmbH (HDW), a company of ThyssenKrupp Marine Systems, is testing innovative lithium ion battery cells on board the solar catamaran "PlanetSolar®". The boat is financed by the German entrepreneur and solar pioneer Immo Ströher. In close cooperation with Knierim Yachtbau GmbH, the shipyard that built the catamaran and the battery manufacturer GAIA Akkumulatorenwerke GmbH HDW will now enter the final development phase for a new generation of energy storage systems that is designed for future use on non-nuclear submarines.


The Chairman of HDW's Executive Board, Mr. Walter Freitag, states: "Lithium ion technology is an enormous step forward for submarine batteries. These cells were developed by GAIA, with the support of HDW and exclusively for us. In comparison to the lead acid batteries commonly used so far on board submarines, they feature much greater capacity and a longer life expectancy. In addition, they are virtually maintenance-free. Due to the very high demands in the submarine construction sector and in order to ensure operational safety on board, HDW has developed a comprehensive safety concept for system integration. The solar catamaran is the prototype for first operation of the lithium ion technology on board a manned vessel."

Submarine Salvatore Todaro, Project 212A



(photo warships.ru)
Creation in Germany submarine of project 212 are more likely to mean the beginning of a technological revolution in the field of non-nuclear submarines, since it is the first production by a submarine with a combined power plant in the central part of the diesel-electric plant and an electrochemical generator.

Work on the project 212 were initiated by German firms in 1988. An intergovernmental agreement between Germany and Italy on the joint development and construction of buildings of the project 212 submarines was signed in 1994.
Bookmark submarine for the Navy of Italy S526 "Salvatore Todaro" was held in 1999, the second boat was laid in 2000. It is planned that in the future for the Navy of Italy will be ordered two more submarines of this type.

Construction Project 212 submarine is traditional for German submarines. Durable housing consists of two cylindrical sections of different diameters, connected by a short conical section. In the forward torpedo tubes are placed with the systems of fire, batteries, central office, premises and systems of the crew. In the connection section contains the fuel cell stack of polymer electrolyte membranes. In the stern section of smaller diameter are the main modules of power plant, which operates automatically and when working in normal mode does not require maintenance personnel. Main ballast tanks are located in the fore and aft ends of the outer hull. ? In the aft located also shockproof containers with liquid oxygen and steel tanks with a source of hydrogen - metal hydride.

New in the construction of the German submarines are the location of hydroplanes on fence cutting and application of X-shaped stern rudders for better handling the boat submerged.

Class 214 & 209 Families


The Class 214 submarines were developed by HDW on the basis of the proven design principles of the family of Class 209 submarines.

In addition, innovative systems from the Class 212A boats were also integrated in the design. The net result was and is an air-independent but non-nuclear submarine with exceptional technical and operational capabilities, featuring extraordinarily developed stealth characteristics and an impressive weapon and sensor payload. Thanks to its modular design, the Class 214 submarine can be equipped with a wide range of optional systems depending on the requirements of the customer navy.Other exceptional features of the Class 214 submarine are:
  • Considerably extended submerged endurance and low detectability due to incorporation of the proven fuel cell system for air-independent propulsion
  • Minimised acoustic, thermal and magnetic signatures as a result of the mature design and the advanced production technology
  • Increased diving depth capabilities
  • Improved living conditions for the crew
The Class 214 submarine meets all operational requirements for missions in both shallow and deep water areas. Submarines of this class are now being built for the Hellenic and Korean Navies.

What lies beneath: Nazi wreck off Fujairah

Deep-sea mission off Fujairah shores reveals stunning new details behind mystery sinking of World War II Nazi submarine



The two-metre gash near the propellers confirms reports that a British aircraft scored a direct strike on th e submarine

The Gulf of Oman's pithy-black deeps have finally surrendered secrets of the mystery sinking of Nazi submarine U-533 during the Second World War, XPRESS has learnt.
Several years after the discovery of the U-boat on the seabed 108 metres below by Dubai shipwreck hunter and diver William Leeman, a new deep-sea mission in October to the U-boat's final resting place has confirmed a fatal blast hole was ripped into her rear port side, dooming the twin-screwed 76.8-metre-long vessel and 52 crew members to a watery grave.

Clear waters
Capitalising on clear waters and armed with electric underwater scooters and high-powered spotlights, Leeman and his team of recreational divers discovered the two-metre gash near her propellers, confirming reports by RAF (Royal Air Force) Squadron 244 that a British light bomber aircraft had scored a direct strike on the submarine on October 16, 1943.
"This is where she was hit by a depth charge by a British Blenheim that struck from the air," said Leeman, 52, an electrical engineer. "During our last dive, we could see the jagged edges of the hole where she was blown up. That was the moment of truth - the ship then sank to the bottom in a forward motion marking the epic death of 52 German mariners."

Lone survivor
Only one U-533 survivor somehow scrambled to safety from the submarine. Records show mechanic Gunther Schmidt bobbed in heavy seas for more than a day after the sinking and made it to shore only to be taken prisoner, Leeman said.
"How the survivor got out, we can't say," he added.
Discovery of the fatal laceration across the sub's double-hull is an undeniable last link in a chain of clues that Leeman says can now close the book on the demise of the long-range U-boat off Fujairah shores.
"A lot of people have told me I don't have proof that the ship we found is the U-533. If you look at the British and German military records, they confirm this is the submarine that sank. The British recorded a direct hit on the sub, we have a German survivor, and we have dived it."
After more than 10 dives in recent years with seven recreational members of the Desert Sports Diving Club of Dubai, often in poor conditions, Leeman said October's visit led to unbelievable visibility and afforded virtually unobstructed views of the U-533.
"We could see the outline of the submarine from 50 metres," Leeman said. "It was so clear, we didn't even need torches. I could see the snorkel, the gun, the conning tower. It was breathtaking."
After a sweep of the sub's length and breadth, Leeman confirmed that her "back wasn't broken" from the rapid descent and violent collision with the ocean floor. The intact U-boat, however, did slide nose-first into the sandy bottom, leaving her bow partially submerged and stern and propeller exposed.
Given the limited time available and expertise needed to dive at such depths, Leeman said no attempts had been made to enter the submarine's hold, but said all of the boat's contents are presumed to be intact.
In a strange twist, in 1993 the sub's identical sister-ship, U-534, was pulled out at a cost of Dh17.9 million ($4.8 million) from waters between Denmark and Sweden, partially restored, and is now on permanent exhibition near Liverpool, UK.
Long regarded by historians as the last U-boat to leave Germany, the U-534 was said to have evacuated members of the German elite.
Meanwhile, Leeman hasn't ruled out organising a future memorial service at the U-533 wreck site off Fujairah that will hopefully include relatives of the 52 lost U-boat crew members whose bodies remain on the Gulf of Oman seabed to this day.

Leeman's next hunt - lost Italian sub
 In the new year, William Leeman and team will embark on a new deep-sea expedition in search of the Galvan, a sunken Italian wartime submarine now resting in very deep water on the ocean floor not far from the Straits of Hormuz.
"No one has laid eyes on the Galvan since she went down decades ago and we want to be the first to locate and confirm her resting place on the bottom," Leeman said.
"I've got the actual position where it sank, so we want to go out there and be the first to confirm the site," he said.
Historical wartime records chronicling the patrols of the Italian submarine are difficult to come by, Leeman said, making her physical discovery even more precious to historians.

The year the u-boat was sunk in the gulf of oman
U-533 is hit!
"U-533 was on the surface making eight knots when first seen. The pilot lost height and manoeuvred his aircraft to such a position that he was able to make a head-on attack. The U-boat quickly submerged but 10 feet of the stern was still showing as the Bisley made its approach. Four depth charges were dropped, bow to stern, and two were seen to fall in the swirl. The Bisley circled the area and after five minutes the crew were rewarded by the sight of oil rising to the surface. As the oil patch increased, air bubbles and two or three white objects were seen. The pilot also thought he saw a survivor."

U-533's mission in Arabia
Launched on September 11, 1942, the U-533 was attacked several times by British and American navy planes during its first two patrols and 42 days of manoeuvres, before it started its third and final patrol to the Middle East where it roamed the Gulf for 104 days.
According to German records, the U-533 was one of five U-boats sent from Europe in mid-1943 to the Arabian Sea region where the submarine group reportedly sank six enemy ships estimated at 33,800 tonnes.
The U-533 was one of 87 IXC/40 type vessels. However, the design was known for its less agile diving controls under emergency conditions, making it more vulnerable to air attack.

IKL/HDW Type 2000 Submarine

It appears that the "Type 2000" submarine was first proposed to the USN during the Ford Administration when there was a degree of interest in conventionally powered patrol subs for the mid-Atlantic ASW mission.  Nearly a decade later, the design was offered to Australia, where it was apparently the preferred bid, losing only to a far less developed Kockums proposal.  Most recently, in 2001, the design was apparently offered to Taiwan.

Here is a diagram:
