Lightship weight is a very important parameter in our models. Apparently some stakeholders are saying that we overrely on this parameter, but we disagree with that, of course. It's important to note that in the costing literature—because we've looked at that—numerous studies identify the relationship between lightship weight and the construction cost of surface combatants as being the single most important factor. The approach we have taken also reflects best practices suggested by NATO and other independent organizations, such as the United States Congressional Budget Office.
