The Vasco da Gama class is a class of frigates of the Portuguese Navy. Named in honor of the Portuguese explorer Vasco da Gama, the ships are based on the German MEKO 200 design, and are Portugal's major surface ships. Portugal operates three ships of this class, which were built in Hamburg by Blohm + Voss (B&V) and by Howaldtswerke-Deutsche Werft (HDW) in Kiel, using modular construction techniques.
