For many years, one of the main pages in the history of Nizhny Novgorod did not exist. It was marked "Top Secret". This is a page about how modern weapons were forged in the city and region. Today the secrecy stamp has been removed from the Nizhny Novgorod arsenal. This book is one of the first attempts to cover the history of the creation of weapons, which became famous on the fronts of the Great Patriotic War and in peacetime. The book contains unique materials from declassified archives and memories of those who created the weapons and those who owned them. Let's not forget , that after the end of the Great Patriotic War there was a military confrontation called the “Cold War,” which also required weapons. And this war was won. Nizhny Novgorod residents also contributed their labors to it. You will learn much of what is described in this book for the first time.
