The show "Air Power" (2005) referred to the USS Saipan as the worlds smallest aircaraft carrier. The USS Saipan is actualy not an Aircraft Carrier, but an Amphibious Assault Ship.
i dunno about that error, but i have noticed numerous errors in the guncam shows in the description of number of guns and their caliber on some fighters. example: it said the F-86 had 3 .50 caliber machine guns when it has 6. also, it frequently describes .50 caliber machine guns as 50mm machine guns. bad oversight.
