[1] Known components include: Support systems include command consoles, upgraded radio communications, upgraded signature reduction, and new flexi couplings to reduce self noise.
[2] BAE further claims it to have 13,000 hydrophones, many times the number fitted in previous Royal Navy systems[3] and more than any other submarine sonar in the world as of 2010.
[4] A key development is the use of high performance and easily upgradeable commercial off-the-shelf (COTS) processing systems, allowing the introduction of much more sophisticated algorithms compared to earlier sonars.
[5] The processing power of the system is said to be equivalent to 60,000 home PCs.
[3] Swiftsure and Trafalgar Update manager, Captain Ian Hughes said, "A good analogy for the performance of Sonar 2076 is that if the submarine was in Winchester it would be able to track a double decker bus going round Trafalgar Square" (a distance of about 60 miles).
