Coast Guard Specialist Ratings

 

Introduction

Specialist 1942-1948  
    The rating of Specialist was created at all four petty officer grades just prior to World War Two.  The peace time rating structure did not provide for all of the functions needed to accommodate the rapid expansion of the Navy and the need for special skills.  A letter to the Secretary of the Navy dated 21 November 1941 from The Chief of the Bureau of Navigation recommended the Specialist rating.  The Secretary of the Navy's endorsement is undated leaving a question as to the exact date of the establishment of the Specialist rating.

    A circular letter dated 13 January 1942, conveyed the first four of the Specialist letter designators.  Emergency rating badges are distinguished by a diamond with a letter of the alphabet inside the diamond which is below the eagle.   One example is Welfare & Recreation Leader,  a "W" inside a diamond.  Additional letter designators were added with the total for the Navy reaching twenty-two Specialist categories most with sub-categories.  The Coast Guard added six Specialist ratings, some with double letters, as Port Securityman (PS). 

Emergency Service Rating 1948-1957
   A major revision of Navy ratings in 1948 replaces the Specialist with Emergency Service Rating (ESR).  Although, many changes are made in the new ESR structure, the diamond with letter is retained.  The Specialist Welfare (Chaplain's Assistant) (W) becomes Emergency Service Welfare & Recreation Leader (ESW)   All personnel holding an ESR are to be members of the Naval Reserve subject activation only in time of nation emergency.

   Letters are reused as needed.  In example, the diamond M, a Mail Clerk from 1942-1944 is a Underwater Mechanic  from 1948 to 1965.  Sample badge.

Emergency Rating 1957-1974
    The Emergency Service Rating (ESR) is renamed Emergency Rating (ER) and the number of ratings greatly reduced in the conversion of ratings between 1957 and 1964.  By 1965 all Emergency Ratings are abolished with the exception of Telecommunications Censorship Technician - ESK.  In 1972, the ESK rating is reclassified as Information Security Specialist and is disestablished in 1974.

  In the following table, the use of the diamond letter is detailed with duration and disposition where known.
