What a Malaysian frigate can do before its missiles arrive

What can Malaysia do with a new frigate whose anti-ship missiles have been delayed?

It can provide presence and, if suitably equipped, anti-submarine work, but lacks its intended missile-based surface-strike capability.

In the question's scenario, Norwegian anti-ship missiles have been cancelled and Turkish replacements will not arrive until 2030. The frigate can still provide naval presence. Effective anti-submarine equipment and a suitable gun would also leave useful work for the ship while it waits. Its intended missile-based surface-strike capability remains incomplete. Britain's limited anti-ship inventory supplies a parallel example: having enough launchers only because too few ships are in service does not represent healthy procurement.
