What replaces Exocet if it is unavailable?

What changes if Exocet is unavailable?

Harpoon would play a larger role, alongside older anti-ship missiles and the surface-attack capabilities of air-defence missiles.

Harpoon is the suggested alternative if Exocet is unavailable. Its 1977 entry into service makes it a candidate for earlier Royal Navy adoption in this counterfactual. Older anti-ship missiles could also remain available to other operators. Air-defence missiles provide another surface-attack option, with Sea Dart given as an example.
