Not sure about combat efficiency, but it would result in a better looking fleet.

They hit that ship with in 2 HARM missiles, 2 Hellfire Missile, 2 Penguin Missiles, 4 Maverick Missiles, a number of CBU-99 Cluster Bombs, about 40 Laser Guided Bombs using the MK-82 500lb warhead, 1 air-launched Harpoon Missile, 9 surface-launched Harpoons, Naval gunfire, and finally a MK-48 ADCAP torpedo.
