Variance Explanations

Due to the complexity of the integration of the combat, communications and platform systems, more time has been allocated to the design review activities. The construction of main hull sections commenced this year as planned. Construction of the superstructure, where many of the integration issues reside, is not planned to commence until June 2010 and the deferred Design Reviews are unlikely to affect the construction schedule and final delivery date.
