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 HistoryEdit

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 designed 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 a multitude of weapons systems. This included a Mark IV, Heavy Coil - 94B1E6/MAC, two M42 Archer Missile Delivery System Pods, six M870 Rampart 50mm Point Defense Network Turrets, one M4093 Hyperion Nuclear Delivery System Silo, five Mark 55 Castor naval coilguns, and six Mark 57 Arena point defense guns.[1]

The Mark 55 Castors on the Strident-class were known to be of two different types. Three of them were in a "quickshot" configuration, while two of them were smaller Arena gauss cannons.[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.[8]

Ships of the LineEdit


  • 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.
