It is the second part of Kalashnikov's historical, geopolitical and economical series of novels (the sequel to The Broken Sword of the Empire).
The Battle for Skies is essentially the big missing part of The Broken Sword of the Empire—what the author meant to write about the Cold War but didn't include into the first book.
Kalashnikov was deeply touched by the Yugoslavian crisis (Operation Allied Force) in 1999.
Notably, the author draw a distinct parallel between the events in Yugoslavia and the state of affairs in Russia.
Kalashnikov was convinced that it was only an exercise for the "Westerners" (NATO country-members), and that the same destiny would await Russia in the close future.
