'''Tarnhelm{{PAGENAME}}''' was a stealth ship used by the [[Knights-Errant]] during the [[Horus Heresy]]. Built on the orders of [[Malcador (Character)|Malcador]], the Tarnhelm was a small [[Warp Drive]]-equipped vessel, too large to be an [[Attack Craft]] but too small for a patrol ship. The ''Tarnehlm'' was purpose-built on [[Titan]] to infiltrate the [[Sons of Horus]] flagship ''[[Vengeful Spirit]]'' and land a team of Knights-Errant so that the traitor vessel could be marked for a future assault by [[Leman Russ (Primarch)|Leman Russ]]. The operation was launched after the [[Battle of Molech]], and the ''Tarnhelm'' successfully got within range of the ''Vengeful Spirit'' to board Malcador's Knights. However the team was discovered and engaged, and the ''Tarnhelm'' was forced to fire into [[Lupercal's Court]], creating a distraction that allowed the Knights-Errant to escape.{{Fn|1}}
