A few seconds after the frigates and destroyers of the Poseidon Navy ceased fire, exactly one hundred waterspouts bloomed where speedboats had once existed. The boats had never even entered visual range of the oil convoy... but the waterspouts certainly did. The impact of thirty kilograms of depleted uranium wrapped in electrical steel traveling at ten times the speed of sound imparted over 166 million newtons of force, enough to evaporate thousands of cubic meters of seawater, along with any hapless object that happened to be within that area. The resulting waterspouts reached hundreds of meters into the air and were clearly visible over the horizon, where both the supertanker convoy and the "hidden" submarine could see them.
