Heavy Weaponry: The Drone weapon no one can turn off

 

T-20 Seismic Drone
A.K.A. The QuarkBomb

The T-20 marks Russia's replacement of the manned Tank with a UGV deployed only once in the Russia-Ukraine War in late 2023. The Unmanned Drone was a sphere ten metres in diameter and capable of speeds of two hundred kilometres an hour. Its weight is estimated at somewhere between fifty to one hundred tons.

The T-20 marks the use of Quark weaponry on the battlefield. A single quark is split from a proton continuously generating a seismic shockwave that pulverizes bone in living organisms out to a kilometre radius. Unfortunately something went wrong and the device wiped out all living things with a skeleton in a thousand kilometre radius extending west into europe, north-east to Moscow and up into space where it killed everyone on the International Space Station as it passed over the region.

Its nuclear battery will last a million years meaning the region will be reclaimed by plants alone. As a consequence it cannot be turned off without some code transmitted by the controller who apparently perished as Moscow fell within its area of effect.
