UNSC Mako-class Corvette
From Halopedia, the Halo wiki
Template:Ship The Mako-class Corvette was a starship classification in the United Nations Space Command fleet.
Several of such corvettes were at the rebel asteroid base over Eridanus Secundus, used by the rebels as part of their improvised fleet. Others were at the disastrous Battle of Reach and the ongoing Second Battle of Earth. Since they are Corvettes, they most likely carry lighter ship-to-ship weapons. They most likely also carry troops.
These corvettes, according to Cortana, were some of the fastest UNSC warships.
