But Mitt Romney keeps lying about it
"The Romney campaign is moving full steam ahead with a new radio ad that repeats a misleading debate claim by Romney that the size of the Navy’s fleet is the smallest it has been since 1917. The number of ships is actually up a bit since 2007 under President George W. Bush. ...Moreover, Navy officials say it’s silly to compare the size of the fleet in 1917 with that of today...But, facts are irrelevant to the gullible and 'silly' sheep.
