A step up from the Gladius-class Heavy Corvette, the Stalwart does not quite sacrifice its combat capabilities than its lighter counterpart. The Stalwart is a light frigate exclusive to Fleet Admiral Hood's faction. One such Stalwart, UNSC In Amber Clad, commanded by Miranda Keyes participated in the defense of Earth from the arrival of Regret's Fleet and the battle of Installation 05. Many Stalwarts served in the Home Fleet, the UNSC's oldest fleet, tasked with guarding Humanity's most carefully kept secret: Earth. Being the lightest and smallest UNSC Frigates, they are also the fastest and, like her sisters, Stalwarts can enter atmospheric combat zones. Stalwarts are the weakest in direct combat of the three main UNSC Frigates with only 60cm of Titanium-A armor and light weapons. The Stalwart-class light frigate serves as the primary UNSC counter to opposing strike craft. She is outclassed by her sister frigates in overall armor and firepower, but no nearby friendlies will complain about the Stalwart's penchant for shooting down strike craft that would normally breach the perimeter.
