I know the range, yield, atsute and patrol issues but I think on balance it would be worth it for another 5 to 6 astute. You can sort of see a very week argument around dropping the numbers of 45s from the 42s, as you could argue one 45 could do the job of two 42s for protecting a task group that would have needed multiple 42s. A couple more Astute class would be a huge result. Some serious quality assurance problems have been identified in the first boats built. One interesting thing for the future though is that I believe the Common Missile Compartment was at one point going to have an option to host multiple TLAMs in a single tube as an alternative to a single Trident.
