This thesis will examine how Surface Warfare Officers (SWO) received their initial post-commission training beginning with the end of World War II and ending with the training program as of September 2008. Specifically, this thesis examines the reasons why there was no initial SWO training after commissioning and what changed to require initial training. The discussion also addresses the effects of changing the commissioning source to a mix of Naval Academy, Naval Reserve Officer Training Corps and Officer Candidate School. Additionally, the influence of technology and the bipolar world of the Cold War will provide insight as to the appropriateness of the initial training. Finally, the decision to conduct most of the initial training onboard ship beginning in 2003 will be analyzed, especially in light of the decision in 2008 to establish a four-week course in San Diego and Norfolk, which is mandatory for all ensigns to attend immediately after reporting to their ships. Although the world changed from the relatively simple Cold War paradigm in the past twenty years, history provides us with a means to understand why the Navy came to do business the way it did. Understanding why things occurred as they did, leads to lessons that will aid in making future decisions.
