The Sting Ray torpedo is a British acoustic homing light-weight torpedo (LWT) manufactured by BAE Systems. BAE Systems descibe the Sting Ray MOD 1,as the World,s most advanced in service lightweight torpedo system. The original version (Sting Ray Mod 0) was designed in the 1960s and entered service in 1983. It is propelled by a pump jet driven by an electric motor. Power is supplied by a magnesium/silver-chloride sea water battery. The propulsion method combines high speed, deep diving, agility and low noise levels. The weapon is provided with target and environmental information by the launching platform. Once launched it operates autonomously, with tactical software searching for the target using active sonar and then homing in without any further assistance. The software is designed to deal with the employment of countermeasures by the target. The weapon is designed to be launched from fixed wing or rotary winged aircraft and surface ships against submarine targets. Sting Ray has a diameter of 324 mm (12¾ inches) and a length of around 2.6 metres (8.5 feet). It has a launch weight of 267 kg (589 lb), and carries a 45 kg (99 lb) Torpex warhead. It has a speed of 83 km/h (45 knots) over a range of 8,000 metres (4.3 nautical miles). STING RAY MK1. In 2003,a contract was awarded to BAE Systems [worth 440 million pounds] for the upgrade of the existing Sting Ray Mod 0 weapon to Mod 1 standard. The updated weapon would be significantly more capable and is designed to counter modern submarines in either deep or coastal waters. The Mod 1 has undergone an exhaustive range of tests and trials. Defence Procurement Minister,Lord Bach,said The new more advanced Sting Ray will provide the Royal Navy and Royal Air Force with a world class anti submarine capability. Sting Ray Mk 1 combines the proven features of the existing Mod 0 platform,which employed largely analogue technology,with an upgraded homing system utilising modern state of the art digital signal processing. The advance in processing funtionality will improve target detection,classification and tracking both in benign environments and in the presence of countermeasures. Complementing the advance in sonar performance,improvements in shallow water capability have been made possible by enhancements to the propulsion system. These enhancements extend the operational envelope in which the torpedo can be deployed. Provision has been made for software upgrades. The weapon is expected to remain in service until,2025. Currently, Sting Ray torpedoes are the main anti submarine weapons carried by Royal Navy surface ships and aircraft and by RAF Nimrod aircraft.
