				the Navy was reviewing an assessment completed in 2012 and 
				updated in 2014, before Russia's reemergence as a "global power 
				competitor," and the start of the U.S.-led campaign to defeat 
				Islamic State militants in Iraq and Syria. 
				 
				"I would bet a paycheck that it's going to be a number greater 
				than 308 ships, just by virtue of the additive nature of the 
				complexity and the contestants that are confronting us right 
				now," Richardson told an event hosted by Washington defense 
				consultant Jim McAleese and Credit Suisse. 
				 
				The top U.S. naval officer said the Navy was already increasing 
				its purchases of Virginia-class submarines built by General 
				Dynamics Corp and Huntington Ingalls Industries Inc., but would 
				also invest in unmanned vessels. 
				 
				The study is due to be completed this summer in time to inform 
				the Navy's fiscal 2018 budget proposal, according to a Navy 
				official. The Navy's fleet is currently around 285 ships. 
				 
				Republican lawmakers have repeatedly called for an increase in 
				the size of the Navy's fleet, arguing that the sheer number of 
				threats around the world requires more ships to help the United 
				States "project power." 
				 
				Others argue that today's ships are more capable and advanced 
				than in years past, increasing the power and capability of each 
				ship and making the larger fleets of the 1980s unnecessary.
