One of the more powerful weapons on Cybertron, the Missile Turret (also called Nucleon Shock Cannon) is exactly what it sounds like: a turret that fires missiles. Desperate fighters can tear the turret from its base and carry it around, whereupon its ammo becomes (very) limited. Turrets feature a lock-on mechanism equivalent to the Thermo Rocket Launcher.
Missile Turrets were used during the Great War, although not as extensively as the Ion Displacer turrets. After Omega Supreme was activated, Megatron and his men captured a missile turret emplacement and used it to shoot down the giant Autobot.
Using the recently acquired Forge of Solus Prime, Megatron attempted to create a new superweapon. He soon realized without the power of a Prime, he could not activate the Forge, ending up with just a smashed lump of metal. Knock Out mused that the end results didn't exactly stack up to a Fortress-Maximus Grade Nucleon Shock Cannon.
- Nucleon was a powerful but dangerous substance introduced in one of the Transformers comic series.
