There's capital and then operational costs. If a Coast Guard ship heads out of St. John's or a Navy aircraft/ship/submarine transits to the area, they burn fuel but already existed with all their trained personnel. So most of the cost is moving things into position. Expensive, but the asset probably would have been moving somewhere anyway.
