Things like this are the game changers that win wars against much superior forces.
If a nation devises a battle plan based on something that can be eliminated, it can be in a serious world of hurt in short order.
The torpedo was a game-changer. As was the submarine. And the airplane. Antiship missiles have been around since the German Fritz-X of 1943. Heck, they even sank a proper battleship with one.
There will always be game-changers and the game will be changed so that the game will no longer be susceptible to that particular game-changer. Its all a cycle of countermeasure vs countermeasure.
