What would be the ideal hunter-killer submarine for the US Navy?
Short answerA modernized Seawolf is the high-end answer, while Virginia remains the more practical design for building a large fleet.
NotesA modernized Seawolf is the preferred answer when submarine-hunting performance takes priority. The comparison casts Seawolf as the F-22 and Virginia as the F-35: both are capable, but the less expensive design permits a larger fleet. The discussion compares that choice with the Royal Navy's earlier need to buy several adequate ships instead of fewer, slightly better versions. Astute is judged broadly comparable with Seawolf, with differences reflecting national requirements and circumstances rather than a universal winner. Britain's experience designing submarines for smaller crews is also presented as useful to Australia in AUKUS. This is an assessment of design priorities, without detailed performance figures.
