The Thranta-Class Corvette was the main all rounder warship of the (Old) Republic navy. It was produced in large numbers to replace the ageing Hammerhead-Class. The Thranta-Class Corvette was relatively smaller than the Hammerhead, but carried around about the same number of personnel, However, it was even smaller in size compared to the gargantuan Valor-Class battle cruisers of the Cold War and Galactic Civil War.
Prior to the events of the Great Galactic War, the Thranta-Class corvettes acted as peacekeeping vessels in several sectors of Republic space, dealing with disputes and unruly pirate forces that were posing as threats. Thranta-class ships fought in many battles during the Great War, including the battle to end the Mandalorian blockade of the Hydian Way.
