From the days of oars and coal-fired engines to the computerized era of the twenty-first century, The Bluejacket's Manual has been an essential part of the American Sailor's sea bag for more than one hundred years, serving as an introduction to the Navy for new recruits and as a reference book for Sailors of all ranks. Written by a Sailor whose decades of naval service included sea duty in patrol craft, destroyers, and aircraft carriers as both an officer and a "white hat," this newest edition has been overhauled to reflect the current state of the ever-evolving U.S. Navy, adding such things as camouflage uniforms, new ratings, and the Navy Professional Reading Program.
