OK. Let's have a bit of fun.
Think of an India versus Britain conflict situation in the Indian Ocean.
We all know that Britain defeated the Argentinians in the Falklands back in 1982, and are more than capable of holding the Falklands, even with the current depleted strength of the Royal Navy (RN) now. But, can the RN hold up against the newer naval powers?- specifically in this scenario against the Indian Navy in the Indian Ocean.
The scenario is over the US/UK military base in Diego Garcia in the Chagos islands, in say 2016/2017 - i.e. roughly 5 years time.
Diego Garcia
For political and humanitarian reasons, the US decides not to renew its lease over Diego Garcia in 2016, pulls out and stays completely neutral. The native islanders demand the return of their homeland, but Britain decides to retain its military base and reinforce and protect the islands themselves. The islanders/Mauritius enlist India's help, who sees the value in the island for her own strategic advantage, and tries to evict the British.
Looking at the RN expeditionary strength, they are (will be in 2016) especially strong in their Type 45 destroyers and SSNs (i.e. Astute class):

So what are the relative strengths militarily? and how may the conflict progress?
For added fun, we shall say that France decides to also stay neutral (unless Amand decides otherwise), given that the British took the islands from the French back in the early 1800s.
