What is the case for a Royal Navy successor nuclear depth bomb, and what risks would it create?
Short answerA successor might offer overwhelming force against a detected submarine, but the panel emphasizes nuclear escalation and the further danger of attacking an SSBN.
NotesThe discussion considers a nuclear depth bomb as a way to destroy a detected ballistic-missile submarine with overwhelming force. It does not establish that such weapons remain operational: the suggestion that former users retain the concept is explicitly speculative. A brief reference to WE177A concerns dissatisfaction with its slow sinking rate. The principal objection is escalation, since nuclear ASW still crosses the threshold of nuclear use. A separate panel comment adds that attacking an opponent's strategic deterrent creates another escalation risk even apart from the weapon chosen.
