Though some variants still exist in far-flung corners of the Imperium, it is now the Departmento Munitorum standard for Manticores to go into battle bearing four mighty Storm Eagle Rockets. Over time, as Forge Worlds have fallen and humanity's technological lore has been lost behind the veil of mythology, the Manticore's versatility has lessened. Once, these potent self-propelled artillery pieces mounted a variety of devastating warheads.

The Manticore Rocket Launcher is an ancient siege engine that dates back to the earliest days of the Imperium of Man. The standard pattern of the Manticore is produced on the Forge World of Stygies VIII, while the rare pattern of Manticore that makes use of primarily incendiary Manticore Missiles is manufactured on the Forge World of Graia. But the most common type remains the deadly Storm Eagle Rockets, the signature payload of these ancient siege vehicles. Named for the ferocious creature from ancient Terran mythology, the Manticore is armed with 4 long-range artillery rockets capable of firing a variety of different warheads, such as high explosive fragmentation warheads, oxy-phosphor incendiary warheads, air gas warheads to high altitude and surface-to-air interceptor missiles, providing it with an antiaircraft capability. Though not as commonly seen on the battlefield as the Basilisk or the Earthshaker Cannon, the Manticore's versatility gives it a distinct advantage over other artillery. A formidable weapon, the Manticore is capable of firing devastating barrages over incredible ranges. The Manticore, also known as the Manticore Rocket Launcher, is a self-propelled rocket artillery piece used by the Astra Militarum that is based on a variant of the Chimera armoured personnel carrier chassis.
