The book about the Seventh Operational Squadron of the Northern Fleet is devoted to a description of the historical events of its formation and combat activities from the beginning of its formation to the last days of service in the Navy. It fully presents statistical data of all stages of the squadron’s combat activity, describes the creation, construction and development of ships of the latest projects. The described episodes of events during combat service enable all readers of the book to understand that at the forefront of protecting the interests of our Motherland were dedicated admirals, officers, midshipmen and ordinary sailors. All of them showed courage in the most difficult situations in ocean voyages and successfully completed their tasks even in the difficult conditions of the inhospitable Atlantic. In addition, the author makes an attempt to analyze complex processes in the work environment on the squadron and writes about the difficult fate of ship commanders. Unfortunately, a complex historical process expunged the squadron from the Navy, but the rich experience of the squadron in defending the geopolitical interests of our Motherland shown in the book gives hope that it will be in demand by the new generation of sailors, and this is precisely the value of this book.
