The Human-Covenant war is a big part of the Halo franchise. In fact, the narratives of several games revolve around the conflict. And if it wasn’t for Master Chief, then the Covenant would’ve had a good chance of winning the whole thing.

After all, they have some advanced technology, which they use to build things like weapons, armor, and vehicles. That last one is especially true as the alien race has plenty of different machines at their disposal. From powerful starfighters to dangerous ground units, they’ve got some for every occasion. However, if you consider the usefulness and significance of each one, then which is the best?

39 ADP-Class Escort

As the name suggests, these are simple escort ships. They were originally created to protect merchants and pilgrims.

38 DSC-Class Support Ship

The DSC-Class Support Ship is one of the only non-combat vehicles that the Covenant has in its ranks. Its purpose is to deliver food to the troops.

37 Brigantine

You likely haven’t seen too many Brigantines while playing the games. This is because it’s an old type of warship that the Covenant doesn’t use anymore.

36 Carrack Merchant Cruiser

Another old ship is the Carrack Merchant Cruiser. However, they are brought back into service after the Human-Covenant war to be support ships and troop carriers.

35 Tick

The Type-28 Intrusion Vehicle, aka the Tick, is a troop transport that attaches to enemy vessels to allow for quick boarding. Several of them are used by Covenant forces to invade the Pillar of Autumn.

34 Tarasque-Class Heavy Fighter

These days the Tarasque-Class Heavy Fighter has been usurped by the Seraph. But it used to be a strong starfighter for the alien force.

33 RCS-Class Armored Cruiser

RCS-Class Armored Cruisers used to serve as capital warships in the Covenant Navy. With their plasma-based weaponry, they were a major threat to most other vessels.

32 ORS-Class Heavy Cruiser

Few ships in the universe are as useful as the ORS-Class Heavy Cruiser. It mainly utilized for stealth operations, but it’s also powerful enough to be a force in full-fledged combat.

31 Hekar Taa-Pattern Blockade Runners

Another vessel to provide both firepower and stealth is the Hekar Blockade Runner. Its age means the technology is rudimentary yet still effective.

30 CPV-Class Heavy Destroyer

The CPV-Class Heavy Destroyer does just as the name suggests and destroys anything in its way. That’s why it’s usually placed at the front of a Covenant fleet.

29 Blisterback

Several Covenant vehicles are specifically designed to take down their opposition’s air support. One of them is the Blisterback, which keeps the skies clear with its collection of missiles.

28 Harvester

The Covenant like their huge multi-legged creations. Yet, the Harvester is different from most others because the aliens don’t use it to kill. Instead, they use it to mine valuables.

27 Man O’ War

Another ancient vessel, the Man O’ War, is a warship designed using Forerunner tech. So, despite its age, it’s more advanced than most other Covenant vehicles.

26 CAS-Class Assault Carrier

These Assault Carriers are bigger and more heavily armored than many other spaceships in the series.

Along with being a physical threat to opponents, it also works as a transporter of smaller vehicles.

25 Anti-Air Wraith

The name alone indicates what the Anti-Air Wraith is for as it targets any enemies in the sky. It does so by making use of its upwards-pointing fuel rod cannons.

24 Locust

In Halo Wars, it’s important to take down your opponent’s structures. And that’s the job for units like the Locust, which uses its ranged attacks to destroy anything solid.

23 Marauder

The Marauder is a cool-looking two-person tank. Like with most vehicles of this type, it has very strong armor. Plus, it slows down enemy units.

22 Super Scarab

While the typical Scarab is often used to destroy the Covenant’s enemies, the super variant is designed for excavations. Its main purpose is to uncover Forerunner facilities.

21 CSO-Class Supercarrier

The most famous CSO-Class Supercarrier in the series is the Long Night Of Solace.

So, if you’re familiar with that ship, then you know that these vessels are giant. And they deal out plenty of damage too.

20 Vampire

Vampires are a common sight in gaming. However, they aren’t usually small aircrafts equipped with plasma and needle cannons. Just further evidence that the Covenant is a unique species.
