Nulka
In nulka is a decoy generation of electronic warfare . The official name of the US Navy for the entire system is Mk 53 - Decoy Launching System (Nulka) or Mk 53 DLS .
It is produced by the British group BAE Systems and was developed in a joint project between the United States and Australia . Nulka means "be fast" in the language of the Aborigines .
technology
The missile is launched from an expanded and modified SRBOC launcher. For this, the Mk 137 Mod 2 flare launcher of the latest SRBOC development stage - the Mk 36 Mod 12 - will be expanded by two Nulka launchers. In addition, there is a Mk 178 Mod 1 processor power supply per launcher and a central Mk 24 Mod 2 Decoy Launch processor per ship . This significantly simplifies the integration of the Nulka system, as the SRBOC launchers are widely used.
The actual decoy is called Mk 234 Mod 1 . It is located in a container, has a self-diagnosis system and is suitable for all weather conditions.
functionality
Essentially, Nulka decoys are decoys that actively enlarge their own radar signature using a special system in order to deflect radar-guided anti-ship missiles such as the AGM-84 Harpoon or Exocet from their own ships. A special feature of the system is flight control. The tubular missile hovers only a few meters above the water surface thanks to a precisely controlled solid motor with thrust vector control and can also carry out preprogrammed flight maneuvers, which are tailored to the type of threat. The entire system works fully automatically and requires only a small amount of data from the launch platform, so that reaction times are very short.
Platforms and dissemination
By July 2006, a total of $ 400 million had been invested in the entire program. In November 2008, the US Navy's 100th Nulka system was installed on board the USS Higgins . A total of around 800 decoys had been delivered to the participating states by this time. Currently (September 2009) the US Navy is considering equipping its Nimitz-class aircraft carriers with the Nulka system.
