Archer Missiles
From Halopedia, the Halo wiki
Summary
Archer missle pods are used to fire Archer missles from UNSC capital ships. They can fire at very high rates and are armed with varying payload yields. They are found on almost all ships and the round shape of the archer missile pod is very distinct. Unfortunately, Covenant point defense technology can elimenate up to half of the missiles before they reach a target.
Vessels such as the frigate UNSC Commonwealth employ racks of 180 Archer missiles, while The Destroyer UNSC Iroquois and the cruiser UNSC Pillar of Autumn use oversized archer missile pods.
