Worst case is that the sequestration cuts kick in on a month-to-month basis, as the fiscal stand-off between Congress and the president drags on. In early February, in anticipation of having to “operate down” to this worst case, the Navy cancelled the scheduled deployment of the USS Harry S Truman (CVN-75) strike group, which was to be the second of two carrier strike groups hitherto maintained on station in the CENTCOM AOR. Secretary Leon Panetta announced at the time that the U.S. would cut its CENTCOM-deployed carrier force to one.
A strike group brings not just the carrier and its air wing but an Aegis cruiser and/or Aegis destroyers, all with Tomahawk missile load-outs. In multiple ways, U.S. combat power has now been cut in half in the CENTCOM AOR due to the long-running fiscal stand-off. The level of carrier presence is insufficient today to execute a limited-strike campaign against Iran while containing the potential backlash.
