Polaris has been serving as the Ultimate Defence of the United Kingdom since 1969 now, kept nearly up to date with numerous upgrades, and the debate on when and how, or if, to replace it is large and ongoing.

However, in the '80s, there was a brief attempt at a full-on replacement of the system using the Trident-II missile. Arranged to cost around £5bn (OOC: eventually closer to £10bn in acquisitions), it would've been a leap in capabilities over Polaris, or so I believe.

However, it was eventually cancelled under Thatcher after the Falklands War, in favour of upgrading the conventional forces. Her reasoning, it seems, was that atomic bombs didn't win back the Falkland Islands, it was soldiers and planes and warships, and that Britain might need to fight another Falklands in the near future.

Assume Thatcher goes the other way and keeps the Trident Program going. What gets cut to make way for it?

(OOC: This doesn't mean Britain has a 300 ship navy and a 500,000-strong army. The Elizabeth carriers are projected to cost a total of £6.2bn to acquire. Try to be reasonable in your predictions.)
