Type K 130 Ship Class Corvette Best Germany Ship Technology System

The Type K 130 corvettes replace the German Navy's Tiger Class and Albatross Class missile fast patrol boats which no longer meet operational requirements. The K130 corvettes will be based at Warnemunde. The remaining four K130 ships are: FGS Magdeburg (F261) built by Lurssen, launched in September 2006, commissioned in September 2008; FGS Erfurt (F262) built by Thyssen Nordseewerke, launched in March 2007, to be commissioned in 2009; FGS Oldenburg (F263) built by Blohm + Voss, launched in July 2007, to be commissioned in 2009; FGS Ludwigshafen (F264) built by Lurssen, launched in September 2007, to be commissioned in 2010. The K130 corvettes are designed with stealth features, low draft, and highly automated weapons and defence systems to support littoral warfare and particularly for operations of a multi-national crisis reaction force.

The K130 class carries four RBS15 missiles. The missile uses active Ku-band radar homing and has a range of more than 200km. The missile has a high subsonic speed, Mach 0.9, and is armed with a 200kg warhead. The K130 class corvettes are armed with two Raytheon / RAMSYS Rolling Airframe Missile (RAM) 21-cell mk49 surface-to-air missile launchers. The RAM guided-missile weapon system is a naval self-defence system for engagement of hostile aircraft and incoming missiles. The RAM missile has a dual-mode radar / infrared seeker and a range of 9.5km.

The K-130 corvette will be also equipped with the Ewation (Ulm, Germany) UL 5000K electronic-support-measures/electronic-countermeasures (ESM/ECM) system, based on the Aldebaran system developed for Spain's F100 frigate. The system consists of an ESM subsystem, working in the frequency range of 2-18 GHz, and an ECM subsystem for active radar jammning. According to some sources, these subsystems are designated SPS-N-5000 and KSJ-N-5000, respectively.

The system intercepts and analyzes radar signals and classifies them according to data stored in its reprogrammable threat library. It has multiple-target-tracking capabilities and a high signal- and bearing-measurement accuracy. Interestingly, the system does not control the other countermeasures directly but only provides inputs to a combat-management system, which uses multiple data sources (such as radar, Link 11/16/22) to control the countermeasures launchers.

The countermeasures launchers in question will be two Multi-Ammunition Softkill System (MASS) self-protection systems. The system has been developed and is produced by Buck Neue Technologien (Neuenburg, Germany), a subsidiary of Rheinmetall DeTec Group. Altogether, 64 81 mm decoys will be carried in both launchers (32 in each). The decoys are dual mode--infrared (IR) and passive radar--with both elements are present in every round. The launcher has eight magazines with four decoys in each.

Each decoy can provide IR protection across a wavelength range of 3-14 [micro]m, as well as across the radio-frequency (RF) range of 8-18 GHz. The round also provides additional obscurance in the following spectrums: 0.5-1.0 [micro]m (visible, near-IR), 1.06 [micro]m (Nd:YAG laser) and 10.6 [micro]m (C[O.sub.2]) laser). The launch can be directed to any part of side hemisphere of the ship, and the launcher's turn speed is 100[degrees] per second. Decoys can be launched in preset sequences, optimized for recognized threats.
