MonoSC is intended to design Monohull Surface Combatants in the range of between 1000 and 12,000 tons. MonoSC includes an Auxiliary Systems Module that provides capabilities to predict system characteristics, demands and weights for a range of different types of auxiliary systems typically found in surface combatants. For weights not developed from analytical methods in Deckhouse, Hull Structure, Auxiliary Systems, and Machinery, the MonoSC Weight Module uses empirical algorithms based on the large data base of existing surface combatant designs. MonoSC also includes a limited Seakeeping Module.
