Available anti-ship missiles would be used in war

If Green Cheese, Blue Slug, and Short Hellcat had been acquired, might they have been used in the Falklands War?

If the missiles were available on ships operating in the war zone, they would have been used.

Weapons available on ships in a war zone tend to be employed. This does not predict an individual missile’s success. A weapon must first move beyond development and be fitted to a deployed ship. Once it is available in a war zone, wartime use is the expected outcome.
