Russia Launches Upgraded Submarine Missile Cruiser

The Russian Zvezdochka Shipbuilder has launched the K-407 Novomoskovsk, strategic submarine missile cruiser after an interim overhaul and modernisation programme.

Novomoskovsk is the last strategic nuclear submarine to undergo modernisation at the shipyard, and is to be delivered to the Russian Navy.

The vessel is the sixth missile submarine of Project 667BDRM (Delfin Class, Delta-4 by Nato classification), whose service life has been extended by ten years after the overhaul.

The Delfin Class submarines are armed with 16 intercontinental ballistic missiles and form the basis of the Russian sea-based strategic nuclear forces, according to ITAR-TASS News Agency.

The submarines that have undergone similar modernisation include K-51 Verkhoturye, K-84 Yekaterinburg, K-114 Tula, K-117 Bryansk and K-18 Karelia. (Source naval-technology)

NGV Tech wins work with Daewoo shipbuilder

Malaysian shipbuilder NGV Tech has signed a contract with Daewoo Shipbuilding & Marine Engineering to construct two 250-foot training and patrol vessels for the Malaysian navy. 

"In the period of 24 months, we will collaborate to design, build and deliver the naval vessels," NGV Tech Executive Chairman Datuk Zulkifli Shariff said.

"DSME will do the design. The vessel blocks will be transported to Malaysia and we will start joining it together at our 24-hectare shipyard in Sijangkang," Shariff said.

NGV Tech was founded in 1992 and is based in the city of Telok Panglima Garang, in the state of Selangor on the west coast of the Malaysian peninsula. Sijangkang is on the coast of Selangor.

The company offers design, fabrication, installation as well as repair and maintenance services for all type of ships including buoy tender vessels, offshore crew boats, patrol craft, landing craft, harbor tugs, hydro-graphic craft and strike craft.

NGV Tech builds around 40 ships annually in Sijangkang, generating around $160 million in revenues, a statement from NGV Tech said.

HMS Ambush: latest of Royal Navy's next generation of submarines

HMS Ambush, the second of the Royal Navy's new Astute class of nuclear submarines, is powered by a nuclear reactor the size of a dustbin.

It is 97m long, the equivalent of 10 London buses, and weighs 7,400 tonnes compared with the 5,000 tonnes managed by its predecessor, the Trafalgar class. 

It has the biggest "ears'' of any sonar system in service today, with the processing power of 2,000 laptops. 

The nuclear reactor which drives the propulsion system is roughly the size of a dustbin but will last the 30-year life of the boat without needing to be replaced. 

But there are some other big numbers to bear in mind - the first three Astute class submarines (HMS Astute, Ambush and Artful) cost the Government £3.8bn, according to last year's National Audit Office report, compared with an initial contract for £2.58bn. 

That report also showed the project was 47 months late, with an original in-service date for Astute of May 2005.(source telegraph.co.uk)

Indian Navy to Install AIP System on Scorpene Submarines

The Indian Navy is considering a proposal to equip Scorpene submarines, which are under construction, with an air independent propulsion (AIP) system to overcome the risk of detection.

The system, which is being built at Mazagon Dock, enables the boats to stay underwater without having to surface for more than three weeks.

DCNS CEO Patrick Boissier said the company was in talks with the navy and that the system could be integrated into the fifth and sixth submarines in 2018.

The navy is also looking at an indigenous AIP system, which is being developed by the Defence Research and Development Organisation, according to Hindustan Times.

The first Scorpene submarine is expected to enter service in 2015 and the remaining within a span of three years.

India is constructing six Scorpene submarines with transfer of technology from DCNS under a Rs187.98bn ($4.16bn) programme called Project 75. (Source naval-technology)

Submarines to receive new batteries

South Africa's fleet of three Heroine-class Type 209 diesel-electric attack submarines are to receive new batteries as part of their “first minor overhaul”, the Ministry of Defence and Military Veterans says in two answers to Parliamentary questions.

The battery consists of 480 man-sized cells and weighs 250 metric tons, according to a South African Navy briefing to Parliament last month. Navy Chief Director Maritime Strategy Rear Admiral Bernhard Teuteberg at the same briefing said a battery costs R35 million. He also described the overhaul as "major". 

“In order to ensure that the SAS Manthatisi (S101) will be operational for a period of at least eight years on completion of the first minor overhaul, the SA Navy will procure a new battery for the submarine,” the ministry says in answer to a Parliamentary question by Freedom Front Plus MP Pieter Groenewald. “Each submarine will, in turn, be fitted with a new battery on completion of their respective minor overhauls.”

Another answer notes the Manthatisi is “presently in reserve, and has been so since October 2007. The submarine is being prepared to become the first Type 209 Submarine to be overhauled in Simon’s Town Naval Dockyard,” the answer continues. “The SAS Manthatisi will be undergoing an overhaul in accordance with the laid down schedules for this type of submarine. The scope of work for the overhaul of SAS Manthatisi is currently being determined.”

The Manthatisi is the lead-boat of class of three submarines acquired for R8.1 billion as part of Project Wills,a component of the controversial Strategic Defence Package. She was laid down at Howaldtswerke-Deutsche Werft, Thyssen Nordsee Werke, Kiel on May 22, 2001, was launched June 15, 2004 and commissioned November 3, 2005. It arrived in South African waters in April 2006. Her sisters were both commissioned March 14, 2007. The Charlotte Maxeke arrived in South African waters in April 2007 and SAS Queen Modjadji I in May 2008.

In answer to Groenewald's question as to whether the repairs might be done in Germany, where they had been built, the ministry said the Navy was “not giving consideration to sending the submarine to Germany for repairs. The requisite capabilities are being sourced and developed locally, and these capabilities will form the foundation for not only the maintenance of SAS Manthatisi but also the subsequent overhaul of SAS Charlotte Maxeke and SAS Queen Modjadji I, as scheduled in the SA Navy Maintenance and Upkeep Plan for the Medium to Long Term Expenditure Framework.”
