Third K130 corvette launched at Nordseewerke DESTROYERS, FRIGATES, CORVETTES


German Navy was launched and christened. The launch and christening of the vessel, Erfurt, took place at ThyssenKrupp Marine Systems’ Nordseewerke Emden. Erfurt follows sister ships Braunschweig


O


and Magdeburg. A further two corvettes in this class are due to follow by 2008, all of the vessels being built by the ARGE 130, which comprises ThyssenKrupp Marine Systems’ shipyards Blohm & Voss and Nordseewerke Emden, and Lürssen Werft. As previously highlighted in Warship


Technology, the new generation of corvettes is innovative in a number of respects, not least as regards the ships’ reduced radar cross-section and infrared signature, high standard of accommodation (for a crew composed of men and women), and will be the first German naval vessels with an integrated bridge. A high degree of automation means that


fewer onboard personnel are required, and weight and space reserves are available for future installation of a light surface-to-surface missile system, torpedo countermeasures system, and an unmanned air vehicle for reconnaissance and surveillance beyond the radar horizon. The heart of the K130 is the ship’s


Combat Direction System (CDS) which automatically processes data from external sources and onboard sensors, and produces and displays a situation report. Apart from the software developed for the CDS, the hardware includes seven multi-function consoles, four commercial off-the-shelf workstations, four cabinets with additional computing capacity and growth potential, a single large tactical screen, 10 Bus Interface Units (BIUs), two Independent Data Bus Systems, and a Video Bus. For the first time ever onboard a naval


vessel, an Intranet system will be installed on the K130, connecting the Combat Direction System, Communication Network, and Integrated Monitoring and Control System (IMCS), along with the PC Logistics and Administration (PCLOA). The propulsion system consists of two


diesel engines, each driving a CPP via a cross-connected gearbox. With a total output

The third example of the K130 corvette class for the German Navy was launched and christened at ThyssenKrupp Marine Systems’ Nordseewerke Emden in March.


N 29 March, the third example of the new class of K130 corvettes for the


of 14.8MW, a maximum speed of more than 26knots can be reached, whilst with single- shaft propulsion, a speed of 20knots can be obtained. The ships’ electrical plant (440V/60Hz/3


Phase) is supplied by four gensets, each with a power of 570kW via two switchboards with a redundancy of 100%.


Double boost for Pakistan Work on the second F22P (Jiangwei II) class frigate for Pakistan began in China last month and work on the third will begin in June. The ships will be delivered between


2010 and 2012 under a contract worth the equivalent of US$750 million. Naval Spyglass reports that they will have C-802 surface-to-surface and HQ-7 surface-to- air missile systems, and a 76mm gun with two Type 730 close-in weapon systems. It is reported they will have Atlas Elektronik hull-mounted sonar. The Karachi Shipyard and Engineering


Works will build a fourth ship from 2009 to 2013, and if the design proves successful it is likely the yard will also build a second batch.


UAE ‘has plans for corvettes’ The United Arab Emirates (UAE) is reported to be planning to replace its Kortenaer class frigates with a corvette or light frigate design. No formal requirement has yet been issued


for what is reported to be designated as Project Yas. However, press reports suggest the UAE is seeking two multi-role vessels with a length of about 100m.


The Kortenaer class frigates Abu Dhabi and


Al Emirat acquired in 1996 are reported to be laid up due to a shortage of manpower because the Navy has only 2400 men. Six Baynunah class corvettes are being built


by Abu Dhabi Shipbuilding (ADSB) and the sale of the frigates will help pay for their replacements. The most likely customer is thought to be


Pakistan, which has been seeking Kortenaers from Greece, but this has encountered problems. Pakistan is seeking to expand its fleet with second-hand frigates in addition to ships being built by China. Meanwhile the UAE Navy continues


to upgrade its current fleet. A contract is anticipated soon by which ADSB will refit and upgrade the Lürssen MGB 62 (Muray Jib) class corvettes. These two ships were acquired in 1990 and 1991 and require a major overhaul.


MTU will power French FREMM MTU Friedrichshafen will supply the diesel- electric propulsion systems for France’s eight Aquitaine class Frégates Européennes Multimissions (FREMM). The machinery will be based upon four 16-cylinder MTU Series 4000 diesel engines with each of 2200kW. This is MTU Friedrichshafen’s first major


order to equip French naval vessels, and deliveries will begin next year. During the design stage, the company provided solutions for the horizontal exhaust outlet system. The 6000tonne frigates have an overall


length of more than 140m. They will be capable of approximately 27knots with gas turbines, and around 16knots with diesel- electric propulsion.
