Maybe the point isn’t precision, but to cause as much destruction as possible as rapidly as possible.
I don’t get your point. If you are trying to destroy a ship without a nuclear weapon, you need an accurate weapon. Remember this will be coming in facing an array of countermeasures, and close-in weapon systems. The munitions are too expensive they to volley-fire, you have to have a relatively high probability of kill. It’s likely the target will observe the separation of the weapon from the attack aircraft and have a hot reception waiting. This kind of weapon probably costs more per copy than most “warships” in the Iranian “navy”.
Any adversary who cannot counter-measure this system is not worth using it on. Just sink their entire navy with submarines.
