Contemptor Dreadnought Guide — Heresy-Era Walker

Part of our Space Marines hub: every Space Marines guide, lore page and painting tutorial in one place.

What Is the Contemptor Dreadnought?

The Contemptor Dreadnought is a relic war machine from the Great Crusade and Horus Heresy era, a time when the Imperium’s technology was at its height and the Space Marine Legions were vast. Unlike the boxy, utilitarian Castraferrum-pattern Dreadnoughts common in the 41st Millennium, the Contemptor pattern has a more elegant, humanoid design with superior systems and a level of sophistication the Imperium can no longer fully replicate.

Each Contemptor chassis is a priceless relic. When a Space Marine suffers mortal wounds but has experience too valuable to lose, they may be interred within a Dreadnought sarcophagus. The Contemptor’s atomantic reactor gives its entombed warrior more power and responsiveness than older patterns, so it moves with a grace that belies its size, almost mimicking the combat stances of the warrior within.

Those advanced systems come at a cost. The knowledge needed to maintain and repair Contemptors is rare, and each one lost in battle is far harder to replace than a standard Dreadnought.

Contemptor Dreadnought on the Tabletop

In Warhammer 40,000 the Contemptor is a Space Marine Walker Vehicle, a mid-sized Dreadnought that sits between the older Castraferrum patterns and heavier walkers such as the Redemptor and Leviathan. Its signature feature, in most editions, is the invulnerable save granted by its atomantic shielding, which makes it more resilient than most Dreadnoughts against high-AP anti-tank weapons.

Its exact characteristics, weapon options and points have changed between editions, and 11th Edition launched in June 2026. In 11th Edition the Contemptor (listed as the Relic Contemptor Dreadnought) is a Warhammer Legends datasheet, as is the Leviathan Dreadnought, so it isn’t intended for matched play or tournaments; check with your opponent or event before bringing one. If your army includes one, remember the 11th Edition core changes that affect big walkers: cover now gives -1 to hit against ranged attacks, and vehicles don’t gain it just for standing in a terrain footprint, though intervening terrain can still obscure them (see our how to play guide and the 11th Edition rules changes).

Weapon Loadouts

The Contemptor has historically offered a mix of ranged and melee options. These are the classic choices; check your current datasheet for exactly which weapons are available in 40k, as the Horus Heresy kit includes more options than the 40k rules have usually allowed.

Multi-melta

The multi-melta turns the Contemptor into a dedicated anti-vehicle platform. It is devastating at close range and rewards aggressive positioning, and the Contemptor’s durability means it can survive advancing to optimal range.

Kheres Pattern Assault Cannon

The Kheres assault cannon provides high-volume shooting. It’s the anti-infantry and anti-elite option, and enough shots can wear down even tougher targets through weight of dice.

Twin Lascannon

Where available, twin lascannons let the Contemptor operate as a long-range anti-tank gun platform, sitting back on a home objective and punishing enemy armour from across the board.

Dreadnought Combat Weapon

The Contemptor’s close-combat fist hits hard. Paired with a melta or flamer, it lets the Contemptor soften a target with shooting and finish it in melee, and its invulnerable save keeps it fighting longer than many melee walkers.

Mixed Configurations

Two ranged weapons maximise firepower at the cost of melee threat, while a ranged-plus-melee build keeps the Contemptor dangerous at every range. If your army already has melee threats, a ranged build is efficient; if the Contemptor needs to handle anything, go mixed.

Contemptor vs Other Dreadnoughts

Which Dreadnoughts are in your codex, and what they cost, varies by edition, so treat these as role comparisons rather than fixed rankings. In 11th Edition the standard (Castraferrum) Dreadnought and the Venerable Dreadnought are Legends too, while the Redemptor, Ballistus and Brutalis are the current matched-play Dreadnoughts:

Contemptor vs Standard Dreadnought (Castraferrum)

The older Castraferrum pattern is the classic boxy Dreadnought. The Contemptor’s invulnerable save makes it more durable against high-AP weapons, and its weapon options have generally been better.

Contemptor vs Redemptor Dreadnought

The Redemptor is larger, tougher and hits harder, but costs more and lacks the Contemptor’s invulnerable save. The Redemptor is the premium combat Dreadnought; the Contemptor is the more compact middle ground.

Contemptor vs Venerable Dreadnought

Venerable Dreadnoughts trade on the skill of their ancient pilots rather than advanced technology. The choice usually comes down to whether you expect to face lots of high-AP fire, which favours the Contemptor’s invulnerable save.

How to Use the Contemptor — Tactics and Strategy

Midfield Presence

The Contemptor’s ideal position is the midfield, where its mix of firepower and durability creates a flexible threat. It can shoot priority targets, contest objectives and threaten charges against weakened units.

Objective Holding

In 11th Edition, objectives are terrain areas and key positions rather than markers, and control comes from the OC of your models in range. A durable walker in an objective area forces your opponent to commit real anti-tank firepower, and every lascannon shot aimed at the Contemptor is one not aimed at your other threats.

Fire Support

Ranged builds can support from a protected position while your assault units push forward. The invulnerable save makes it harder to dislodge from a firing position than many Dreadnoughts.

Character Support

Techmarines have traditionally been able to repair Space Marine vehicles, which can extend a Contemptor’s life considerably. Check the current Techmarine datasheet. Remember that in 11th Edition a unit can only benefit from one stratagem per phase, so plan which buff or Command Re-roll you want on the Contemptor at the key moment.

Competitive Play Considerations

Points efficiency: The Contemptor shines when it is priced competitively against the alternatives. Check the current Munitorum Field Manual.
Meta sensitivity: Against armies with lots of high-AP anti-tank fire, its invulnerable save is valuable. Against high-volume fire it matters less.
List building: It fits balanced Space Marine lists that want a durable, flexible walker without the cost of a Redemptor or Ballistus Dreadnought.

Frequently Asked Questions

Is the Contemptor Dreadnought good in 11th Edition?

It depends on its current datasheet and points. Its traditional selling point is an invulnerable save that makes it tougher than most Dreadnoughts against high-AP weapons. In 11th Edition, however, it is a Warhammer Legends datasheet, so it is for casual and narrative games rather than matched play.

What is the best Contemptor loadout?

Traditionally, a multi-melta with a combat weapon has been the most popular build, offering anti-tank shooting and melee threat. Kheres assault cannons suit infantry-heavy opponents, and twin lascannons, where available, work for backfield builds. Check which options your current datasheet allows.

Can I use a Contemptor in Horus Heresy games?

Yes. The Contemptor Dreadnought is a mainstay of the Horus Heresy game and has extensive rules and weapon options there. The Heresy rules for Contemptors are different from their 40k datasheets.

How does the Contemptor compare to the Leviathan Dreadnought?

The Leviathan is significantly larger, tougher and more expensive. It fills a heavy fire support or siege assault role that the Contemptor can’t match. The Contemptor is the more compact, affordable option; the Leviathan is the premium choice when points allow.

Is the Contemptor a Legends unit?

Yes, in 11th Edition. The Relic Contemptor Dreadnought datasheet is in Warhammer Legends, so it isn’t intended for matched play. Legends status can change, so check the latest updates if you want to use one in a tournament.

Is there a plastic Contemptor Dreadnought kit?

Yes. Games Workshop released a plastic Contemptor Dreadnought in 2022 as part of the Horus Heresy relaunch, replacing the older resin Forge World model as the standard version. The kit is built for Horus Heresy games, but it is also the model used for the Contemptor in Warhammer 40,000. Check which weapon options your 40k datasheet allows before you glue it.
