Correcting Obama's Debate Comments on the United States Navy

Earlier this evening in the Third Presidential Debate Mitt Romney raised legitimate concerns about the current and shrinking size of the United States Navy. The President responded snarkily by saying that size does not matter because we have these these "things" called Carriers that "planes can land on" and these "things" that go underwater.

This pathetic attempt at rebuttal by Obama is quite simple. The first submarine commissioned by the United States Navy was "USS Holland (SS-1)" on October 12, 1900.

The first Aircraft Carrier commissioned by the United States Navy was the USS Langley (CV-1) on March 20, 1922. 

Exactly how does the existence of Aircraft Carriers and submarines in a Modern American Navy nullify Mitt Romney's  just concerns about the size of the Navy? Obama spoke about both as if they were some new fangled advances in naval warfare. The existence of carriers in our fleet justifies its reduction even though they have been an integral part of our navy for 112 and 87 years respectively? I guess in Obama's world Jimmy Doolittle was bombing Tokyo with ELECTRONIC b-25 Mitchell bombers. How can he defend shrinking a navy whose history he is wholly ignorant?
