The CC submarines will incorporate a number of next-generation technologies. Many of these will be borrowed from the Virginia-Class (VC) attack submarines. This borrowing will permit the CC submarines to be the most advanced in existence while reducing the costs that custom development would require.
One of the VC features will be what is referred to as a “fly-by-wire” joystick control system. The automated control fly-by-wire navigation system utilizes a computer that is integrated into the submarine’s control systems. Algorithms are able to maintain course and depth through signals sent to the rudder and the stern.
Another VC feature that will be on the CC submarines is the large aperture bow array sonar (LABAS). Sonar systems send out acoustic singles called “pings” which are reflected back by objects in the water. Analysis of the return signal carries information about the shape, location and dimensions of an object. Unlike other sonar systems, the LABAS is water backed with no dome. The small hydrophones that detect the returning acoustic signal are intended to last the life of the submarine. Currently sonar hydrophones have to be replaced every ten years. This innovation alone will save a great deal of money.
The CC submarines will also contain the submarine combat system from VC attack submarines. The combat system includes electronic surveillance measures, periscopes replacements, radios and computer systems.
The drive shafts on the CC submarines are being constructed to be able to last from ten to twelve years. This will help to synchronize the submarine maintenance schedule which will also save money. Current drive shafts in submarines only last between six and eight years.
VC communication systems will be incorporated in the CC submarines. This advanced communication system replaces the traditional periscope in submarines with a camera mast that is connected to a fiber-optic cable. This means that crew members will no longer have to physically stand under the periscope in order to view things outside of the submarine. One benefit of this new viewing system is the fact that communication and control equipment can now be moved to larger and better protected sections of the ship because it no longer has to be located high up near a physical periscope.
The CC submarine design features a new electric motor which will turn the shaft and rotor to propel the ship. The new engine will be more efficient than the old type of motors. It may also give the CC submarines some tactical advantages.
Prior to the awarding of the contract to GDEB, the Navy contracted for work on missile tubes and hull forging. This work was part of a collaboration with the U.K. on the creation of common missile compartments. The U.S. and U.K. have been cooperating on the purchase of parts for the common missile compartment. The U.K. is planning on the construction of four nuclear-armed ballistic submarines which will each have twelve missile tubes. On a side note, there is a fierce debate going on in the U.K. about whether or not the U.K. should continue to construct, maintain and deploy nuclear-armed submarines.
