Submarine (Clancy book)

Submarine: A Guided Tour Inside a Nuclear Warship is a non-fiction book written by Tom Clancy and defense systems analyst John D. Gresham. Released on November 1, 1993, it is the first entry in Clancy's Guided Tour series of non-fiction books, which explore several different facets of the United States military. Submarine particularly explores the inner workings of two submarines, USS Miami (SSN-755) and HMS Triumph (S93).

Some editions of the book have a photo section in the middle; some have a special chapter on the Seawolf-class submarine and Virginia-class submarines. The chapter 'Other people's submarines' has the history and other information about the submarines of other countries. The foreword in the Penguin edition was written by Vice Admiral Roger Bacon. An edition of this book also includes diagrams of various submarines.
