Abstract
A submarine is provided with a large number of individual fins, some of which are arranged to create a 'slot' effect between them. The fins are controlled in a way which is dependent on which of them may be in service at a particular time so that manoeuvreability is substantially unaffected by damage to a limited number of them.
