The Mark 57 Arena point defense gun is a kinetic point defense gun utilized by the UNSC Navy after the Human-Covenant War. The Strident-class heavy frigate had six individual Arena turrets, with each pair being mounted in a 'quickshot' configuration on three of its Mark 55 Castor naval coilguns.[1][2]
