The Navy should try and maintain OFRP to get carriers to a consistent maintenance schedule, while also mitigating carrier gaps by exploring other options, said Bryan Clark, a senior fellow for the Center for Strategic and Budgetary Assessments, an independent, nonprofit institute focused on national security strategy. “As we saw with Bush, the Navy’s carriers are suffering from the effects of repeated, prolonged deployments without adequate maintenance,” Clark said. He said the Navy could use Joint Strike Fighters on large-deck amphibious assault ships, allowing about 20 strike fighters to support operations against the Islamic State during gaps in carrier presence. OFRP can still work, even with longer maintenance periods, but that means ships will have less time in the sustainment phase after a deployment, Clark said.
