"By the time a heavy corvette is discovered, it is usually far too late to begin evacuation."
―Specialist Eric Waller

The Cheraika-pattern heavy corvette, classified as the SDV-class heavy corvette by the United Nations Space Command, is a large patrol ship that was utilised by the now-defunct Covenant Empire. A common sight in both Covenant territory and uncharted space, the Cheraika-pattern is typically deployed as a generalised support ship that can conduct a very large number of roles.

Crewed by newly-inducted warriors and inexperienced officers, the Cheraika-pattern is a highly-adaptable starship, and can be easily modified to emphasise a number of aspects of its design. This is mainly thanks to the structurally-strong selvage ring that runs around its perimeter, which are littered with hardpoints that can accept specialised modules. In its unmodified state, heavy corvettes are particularly adept at transportation, exploration, and planetary assault. Swift and capable of operating alone for months or years at a time, they are difficult to detect thanks to a basic set of stealth field generators. This ensures they can covertly map large regions of space or bypass orbital defences in order to set up a forward base for invasion forces. This can also mask any external cargo that may be carried in its gravity field between the lower rim. However, they make for poor warships, as their shields are light for their size and most of their weapons are chosen for their effectiveness against ground targets and small attack ships. As a result, an SDV-class must avoid confrontations unless they are being backed up by larger warships better-suited to ship-to-ship combat.

Weaknesses and Counter-Tactics




Templar-pattern heavy corvette

The Templar-pattern heavy corvette is one of the newest models of SDV-class heavy corvette, manufactured exclusively for the Swords of Sanghelios. A slight modification of existing patterns, the few changes the Templar has introduced has improved the ship in many areas. While it sacrifices some of the modularity the class is famous for, it has removed most of the structural weaknesses present in Covenant-built starships, allowing it to last longer in battle. Also of note is that it now boasts permanent communal quarters for some of its crew, which they can use for rest during long expeditions.
