From Halopedia, the Halo wiki
The C712 Longsword is a multirole space fighter, and its weapons loadout can be easily modified for different mission requirements. It has eight M9109 coilguns that fire 50mm rounds at enemy fighters and ground forces during tactical strikes. There are four ASGM-10 missiles, which are specialized for use against singleships such as the Covenant Seraph, although they are powerful enough to deal significant damage to targets not protected by energy shields. These are typically housed in a rotary launcher within the internal ordnance bay, to protect the missiles prior to launch. If needed, it can replace its anti-ship missiles with conventional smart bombs, satellites, or special mission payloads.
