Does anyone have information, specifications, or drawings of the Royal Navy SSNOX, SSNOY, and SSNOZ attack submarine designs?
According to Rebuilding the Royal Navy: Warship Design Since 1945 by DK Brown and George Moore:
Then a Rand Organization white paper titled The United Kingdom’s Nuclear Submarine Industrial Base Volume 2 by John F. Schank et al. states that the SSNOZ was a post Trafalgar class design:
My understanding was that the SSN20 was also known as the "W-class" attack submarine.
According to Rebuilding the Royal Navy: Warship Design Since 1945 by DK Brown and George Moore:
There were a large number of design studies for the next class known as SSNOX, SSNOY and SSNOZ. These were splendid designs but far too expensive, and it was agreed that the Trafalgars should be "Improved Swiftsures".
Then a Rand Organization white paper titled The United Kingdom’s Nuclear Submarine Industrial Base Volume 2 by John F. Schank et al. states that the SSNOZ was a post Trafalgar class design:
http://wwwcgi.rand.org/pubs/monographs/2005/RAND_MG326.2.pdfThe SSNOZ (the original name for the class) was to represent a major change in capability from the Trafalgar class, which by contrast had been an evolutionary upgrade from the Swiftsure class. The SSNOZ became SSN20, whose features were to include an improved nuclear propulsion plant, an integrated sonar suite, a large increase in firepower, new combat systems, a larger pressure hull with new steel, increased stealth characteristics, and control surfaces modified for enhanced agility.
My understanding was that the SSN20 was also known as the "W-class" attack submarine.
