==Design==
All submarines face design tradeoffs. In Trafalgars, and the preceding [[Swiftsure-class]], for a variety of reasons, small size was important. In the Cold War, this could limit the submarine's habitability, and other factors limiting it to European [[anti-submarine warfare]] &mdash; but that was precisely the NATO mission of Britain. Today, however, there is a role for small submarines in [[littoral warfare]], in that they can operate in more confined waters than a submarine optimized for [[blue water]] operations.
 
As demonstrated in the [[Falklands War]], a submarine, moving ahead of the main task force, has a key mission of [[sea denial]]. The Royal Navy describes this submarine mission as <blockquote>The SSN is used to great effect when the submarine is deployed in advance of friendly forces in order to reduce the flexibility of an opposition force by denying the use of an area or region. This is known as regional sea denial. <ref>{{citation

| title = Fleet Submarines (SSN)}}</ref></blockquote>
 
Small submarines also have advantages for intelligence collection, both strategic and tactical, and for surveillance and reconnaissance as part of combined operations.
 
The ''[[Astute-class]]'', which will replace both the Trafalgars and [[Swiftsure-class]]es, has grown in size, with sensors and silencing mentioned as factors. Greater automation, however, will allow a smaller crew, and thus greater habitability and range. <ref>{{citation
