The idea to drop a bomb on a big city in Ukraine by delivering it with a space rocket belongs to Dmitry Rogozin, former head chief of the russian Roscosmos state-owned space corporation, Bild reports.
The German media obtained phone recordings of Rogozin talking this idea over with Dmitry Baranov, director of the JSC Progress Rocket Space Center.
The plan is: to take a Soyuz space rocket, most probably the Soyuz-2.1 version designed to deliver spacecraft to orbit; implant a ready-made air bomb into the rocket, given the discussed parameters, they talk FAB-9000; and launch it along a ballistic trajectory onto a major Ukrainian city as a projectile from Plesetsk Cosmodrome spaceport in Arkhangelsk Oblast, russia.
Indeed, the non-aerodynamic, roughly-shaped FAB-9000 will rather simply fall apart during entry into the atmosphere solely due to its aerodynamic properties, let alone problems with "overheating", which in theory can be solved by applying ablative protection.
Then, there is the question of accuracy and guidance. This part would basically require a whole new development of a "bomb" that would be able to steer during the flight at truly hypersonic speeds, similar to the guidance and flight control systems employed in re-entry vehicles of an intercontinental ballistic missile. Without these components, the accuracy error will be around 100 to 150 kilometers.
In summary, just take a ready space rocket and a ready air bomb, combine them together and launch on another country is just the right illustration for the mindset of Dmitry Rogozin who was in charge of the whole russian space industry throughout the four years he was the head of Roscosmos, and the level of degradation russia suffered in this field.
On a side note, Bild reports that the concept was presented to russian president Vladimir Putin on January 16th this year. According to Rogozin, "the great and terrifying" Putin liked the idea.
