Orbital Strike Cannon (Minecraft)
The Orbital Strike Cannon is a player-built redstone and TNT machine in Minecraft Java Edition that drops a TNT payload on almost any coordinate you give it. It was created by the technical YouTuber cubicmetre, and it is not an official item.

What it is
A TNT cannon that fires at coordinates
The cannon is a huge machine built in survival with redstone and TNT. You enter the target coordinates at a terminal, the machine builds a TNT payload, holds it in place, then launches it so it lands on the target.
cubicmetre has built it in versions Mk.1 to Mk.6, plus a smaller Minimal Signature variant. It works in vanilla Java Edition only, and most Paper or Spigot servers break it.
It went mainstream through Wemmbu's Unstable SMP videos, where players call down strikes with a fishing rod. That version is scripted, not vanilla redstone. See what's real and what's staged.

Questions people ask
Is the Orbital Strike Cannon real in Minecraft?
Yes. cubicmetre's cannon is a real machine built from survival redstone and TNT in vanilla Java Edition. The fishing-rod version from Wemmbu's Unstable SMP videos is different: it runs on server scripts and was staged for the story.
Who made the Orbital Strike Cannon?
The technical YouTuber cubicmetre. It has gone through versions Mk.1 to Mk.6, plus a smaller Minimal Signature variant.
Is the Orbital Strike Cannon an official Minecraft item?
No. It's a player-built machine, not an item or block you can find or craft.
Does the Orbital Strike Cannon work on Bedrock?
Not as a vanilla build. It depends on TNT duping, which only works in Java Edition. Bedrock players use add-ons instead.
