The Broken Sword of the Empire (Russian: Сломанный меч Империи) is a book by Russian author Maxim Kalashnikov, first published in 1998 by the Great Resistance publisher.

It is the first part of a historical, geopolitical and economic series by the author.

The Broken Sword of the Empire is a historical/geopolitical analysis of Russia in the period from the 1930s to the 1990s.

It is true that the elements exposed in the book are very hard to find anywhere else, like the AYaKS aerospaceship programme, the Soviet plasma anti-friction generator, the Ekranoplan programme, and names of Soviets that fought in Korea, Cuba, Algeria, Vietnam, Egypt, Somalia, Syria, Afghanistan but also on the territory of the Soviet Union.

To Kalashnikov, those people were the "Hammer and Sword" of the Soviet nation.
