Straight from the Anti-Furry Coalitions concept sketches, the TTMK1, preferably known by the GFA as the "Troll TNT" due to it's ability to explode even when it's successfully defused.
The Troll TNT, despite being called a"TNT" is actually a small hydrogen bomb, that combines both nuclear fusion and fission, making it far more destructive than a traditional atomic bomb. The fission "primary" stage of the bomb generates the immense heat and pressure needed to trigger the "fusion" of light hydrogen isotopes, releasing the massive energy of the hydrogen bomb. It was reported by GFA agents that the TTMK1 was 20 times more powerful than their ":3 bomb".
The Troll TNT was only slightly surpassed the GFA's later attempt at their own H-bomb, the "Boykisser V1"
History
The first TTMK1 was tested on the 5th of June, 2011 at the White Sands Testing Grounds in New Bloxico, it was parachuted by a stolen GFA hypersonic bomber, as the bomb instantly armed the moment it fell from the bomb bay.
Transcript of test
Pilot: 20,000 feet, open bomb bay doors
Bombadier: I got visual on the sweet spot
Engineer: OK! Once that bomb falls, we get the hell out of here
Pilot: copy that.
Bomadier: Bombsight computer confirms were right on target
Engineer: Realease, release!
Bombardier: Bombs Away!!
*the engines rev to hypersonic speed*
Copilot: ETA till impact, 5 seconds
*A bright flash and loud explosion is heard, and a trollface rises into the sky*
Bombardier: Hit confirmed! 2 miles northeast of the original target zone! Seems like the blast zone destroyed an unidentified communications relay, seems to be of GFA origin.
Pilot: Job well done boys! With this bad boy, we can fool those stupid furries into thinking they've defused it, but once they thought they have... BOOM!
*crew laughs*
Copilot: Alright, let's head home, these bean burritos are NOT sitting right in my stomach thank you!
