The Acastus Knight Porphyrion is a class of Imperial Knight.
One of the most heavily armed and armoured of all the Knight chassis in service, the Acastus Knight Porphyrion rivals even the Scout Titans of the Collegia Titanica in terms of size and power. Armed with weapons that can obliterate even the most heavily armoured target, it is truly a force to be reckoned with. Taller than even Cerastus Knights, the Knight Porphyrion is a dominating presence on the battlefield.
The Knight Porphyrion's primary weapon are a pair of twin-linked Magna Lascannons and either a carapace-mounted Ironstorm Missile Pod or Helios Defense Missiles. In addition, it was equipped with a pair of Autocannons, Lascannons, or Irrad-Cleansers. For protection the Knight Porphyrion utilizes an Ion Shield.
Due to its immense size, power, and complexity few Knight Houses could afford more than a handful of these mighty machines.[2a]
