The Strident-class heavy frigate is a frigate class employed in the Post-War UNSC Navy; utilized primarily for escort of larger capital ships and for rapid offensive engagement.[2] The UNSC Infinity can carry ten vessels of this class within internal docking bays.[3] The class was manufactured by Aerofabrique SA at shipyards at Tribute and Mars.[1]

Class History[]

The Strident-class heavy frigate came into service in October 2552.[4]


Many Strident-class vessels were sent out to fight Covenant remnant occupiers out in the Outer Colonies.[1]

At least one of these vessels, UNSC Eminent Domain, assisted during the Battle of Draetheus V. It destroyed hundreds of Spirits and outmaneuvered the Covenant vessels in an attempt to deploy a unit of Orbital Drop Shock Troopers before it was heavily damaged and crashed into the surface of X50.[5]

Several Stridents of Battlegroup Dakota participated in defending Earth from the Ur-Didact.[6]

During the Second Battle of Requiem, UNSC Infinity deployed her compliment of Strident-class frigates shortly after arriving at the shield world; at least two would survive the initial phase of combat.[7]


The Strident-class has been designed primarily to try and fix the issues of the previous frigate classes. It is known to blur the line between frigate and destroyer.[1]


The Strident-class has three engines.[8]


The Strident-class has a multitude of weapons systems. This included:

  • 1 Mark IV, Heavy Coil - 94B1E6/MAC[1]
  • 2 M42 Archer Missile Pods[1]
  • 6 M870 Rampart 50mm Point Defense Network Turrets[1]
  • 1 M4093 Hyperion Nuclear Delivery System Silo[1]
  • 5 Mark 55 Castor naval coilguns - The Mark 55 Castors on the Strident-class were known to be of two different types. Three of them were in a "quickshot" configuration paired with two smaller Arena gauss cannons.[1]
  • 6 Mark 57 Arena point defense guns[1]



The Strident-class could only carry one Pelican inside a hangar. However, an additional three could dock with the ship at exterior hull clamps.[1]


The Strident-class can carry up to four Pelicans.[1] They also carry a number of Orbital Drop Shock Troopers and SOEIVs.[9]

Ships of the Line[]


  • The Strident-class and Paris-class heavy frigates are the only design of frigate with no vehicle hangar located at the bottom of the ship. Instead it is replaced by a shuttle bay on each side of the ship.
  • This is the first class of UNSC frigate known to be equipped with energy shielding, an unprecedented augmentation to its combat effectiveness.
  • This class is 575 meters long, making it the largest known frigate class put into service within the UNSC Navy.
  • 343 Industries used a Strident-class heavy frigate to represent UNSC Forward Unto Dawn in Halo 4 instead of the original Charon-class used in Halo 3.
