I think there are a number of things. One is enhancing our intelligence, surveillance, and reconnaissance capacity. We currently have a fleet of maritime patrol aircraft that has just been upgraded, but only 14 of the fleet have been upgraded. I think there's the potential to at least look at expanding that upgrade program to include the entire fleet, which would give us better coverage, particularly because when we first acquired those assets we weren't using them in an overland surveillance role like we are currently doing in the Middle East. Some of those aircraft are doing things that weren't factored into the analysis when the initial assessment about fleet size was made.
Beyond that, I think we need to build into our future surface combatants a sophisticated anti-submarine warfare suite and its capabilities because, as the Russians are demonstrating right now, they have advanced submarines, and they are continuing to develop that technology. Then, I think, the third major thing is that we need to life-extend our existing fleet of submarines and look quite seriously at ways forward to acquire new ones.
