The following are all known formations that make use of Dreadnought Drop Pods:

3 Adeptus Mechanicus Technical Specifications.During the Great Crusade and Horus Heresy eras of the late 30th and early 31st Millennia, the Dreadnought Drop Pod was widely used by the Space Marine Legions however many Legions preferred the more mobile, multi-role designs of Drop Pod like the Dreadclaw, as these craft could take off again after landing, were useful in ship-to-ship combat and were armed for protection against enemies. As with any craft that suffered from such a high attrition rate in battle, Dreadnought Drop Pods are highly valued and invariably always in demand with those who use them most. These vehicles are tithed directly to various Space Marine Chapters with whom the Archmagi Forgemasters have protective treaties and ancient debts. The most common pattern of Dreadnought Drop Pod is the Lucius Pattern, manufactured principally on the Forge World of Lucius in the Segmentum Obscurus. The intense stresses caused by the Dreadnought Drop Pod's larger engines and support-free interior space are such that only the highly armoured shell of a Dreadnought could hope to survive the descent to the ground without being pulverised on impact.

The internal space of the pod is wholly dedicated to transporting a single Space Marine Dreadnought, of any type or pattern, and the design of the craft allows for the Dreadnought to be transported to the battlefield with the minimum of delay. Where internal seating and support harnesses are found in the infantry pods, a Dreadnought Pod is empty, and the five outer ramps are replaced with three larger ones. The Dreadnought Drop Pod is a larger variant of the standard Drop Pod, featuring more powerful thrusters and retro-rockets. Having made what is little more than a controlled crash landing, explosive bolts are released and the armoured doors of the pod open, allowing the enclosed Space Marines to deploy. The Drop Pod plummets through the planet's atmosphere at meteoric speeds, firing powerful retro-rockets just before touchdown to rapidly slow its descent. A Drop Pod is a one-way, sealed, armoured landing craft that is launched from an orbiting voidship onto the planet below. The Dreadnought Drop Pod, officially the Lucius Pattern Dreadnought Drop Pod, also known as the Lucius Pattern Heavy Drop Pod, is a specialised variant of the common Drop Pod used by the Adeptus Astartes for planetary assaults.
