Babcock's Astute class weapons handling and launch system discharges Tomahawk missiles
When complete, the latest trials will confirm successful operation of the weapon launch system over a range of speeds and depths, and coherent performance of the complete combat system, enabling BAE Systems and Babcock to demonstrate that the design meets the specified performance requirement.
The Astute class WHLS is capable of carrying more torpedoes and tube-launched missiles than any previous class of Royal Navy (RN) submarine, optimising firing profiles for the range of weapon types that the system can carry.
The weapons handling system comprises equipment to embark, store, reposition and load weapons into the launch tubes. The weapons stowage compartment features a configuration developed to provide the highest packing density of weapons, and a unique method of shock mounting to provide adaptable protection according to the number of weapons stored on each stowage tier. This improves crew safety and maximises potential for the system to continue to function following a shock event.
The launch system is the first on a RN submarine to use Babcock’s advanced air turbine pump (ATP) and programmable firing valve (PFV) technology to provide a positive firing mechanism and control the firing air profile to match precisely the launch requirements according to factors such as weapon type, speed, and depth.
Commenting on the successful trials, Babcock project director Gavin Borland said: “We are delighted to learn of the successful launches of TLAM missiles by HMS Astute , which provides further demonstration that the Astute class weapons handling and launch system meets the fundamental performance requirements of this highly potent and technologically advanced submarine.“
Babcock is currently supplying the WHLS for Astute class boats 5 (Anson) and 6.
