Prowler

UNSC Prowler You may also be looking for the Jiralhanae Vehicle  The UNSC Prowler is a corvette classification within the United Nations Space Command. They were used exclusively by the Office of Naval Intelligence and were often crewed by select ONI crews.

This is most probably the UNSC equivalent of the Covenant Stealth Corvette.

Role
As per its namesake, it is used to gather electronic intelligence, and its primary role is to stay hidden while safely gathering such intel, not to charge into battle, as that would invariably be an irreversibly fatal tactic. Because of its tactical value and potential to change the outcome of any given combat situation, every UNSC Battlegroup has a Prowler assigned to its ranks.

The Prowler's only combat role, beside active combat monitoring and recording, is discreetly laying minefields of stealthed plutonium HORNET mines. When enemy warships enter these deadly minefields, they will most often be destroyed. This stratagem allowed Battle Group Stalingrad to survive longer at the Battle of Onyx.

However, in dire combat situations, the Prowler was armed with "minimal weapons systems". Six of such stealth starships could destroy a single Covenant Heavy Destroyer. The UNSC Prowler was also unusual in possessing two or more pulse lasers.

The Prowler Dusk was the only known prowler to be manned by a none ONI crew.
