Although the hydroplanes, rams and hydraulic supply are excluded from the scope, the autopilot, operator’s stickwheel and means of signal transmission from there to the hydromechanical ram-servo units which modulate the hydraulic flow are all included. On Trafalgar Class submarines, the autopilot is a hydraulic analog computer and signalling is by both hydraulic and analog electrical means. On Vanguard Class, the signalling is electronic using a mixture of microprocessor and analog technologies. Electronic depth distribution and indication system aboard Trafalgar and Vanguard class submarines: This system uses analog sensors and data distribution to drive digital depth indicators throughout the submarine, and also to provide signals to other client equipment outwith the contract scope. Hover and Missile Compensation computer fitted to Vanguard class submarines: This microprocessor based system interfaces with multiple sensors, valves and pumps to provide fine buoyancy and trim control of the submarine. Some of the equipment is designated as “First Level” as its correct operation is critical to the safety of the submarine and its crew. The contract will contain both lists of items that shall be priced during the competitive tender process and also lists of items that need only be priced upon receipt of a direct request from the Authority if required during the course of the contract.
