USS CASIMIR PULASKI SSBN-633

Fleet Ballistic Missile Submarine
FBM boats had two crews designated Blue & Gold
They rotated on an approximate  ninety day cycle.
    I made a "routine" patrol aboard this fine vessel in the Spring of 1967 (Blue crew). I was a Senior Chief Firecontrol Technician (FTCS) and was responsible for the "block-house" or Missile Control Center. We deployed from Rota, Spain. We submerged near the hundred fathom curve and surfaced more than sixty days later. During the "off crew" period following this patrol, I was promoted to Warrant Officer (W-1) and transferred to the Naval Ordnance Test Unit at Patrick Air Force Base for 'shore duty'. Spent about 23 months of that two year tour on temporary duty (TAD) aboard U.S. & U.K. FBM Submarines! Responsible for the instrumentation package (~100 ton) and team for Demonstration and Shakedown Operations (DASO).
 

A very significant morale item for all military personnel in all branches of service was always "mail call". In the tradition of the Silent Service all electromagnetic radiation was controlled to preserve our security. Outgoing personal communication was totally out of the question. The FBM submarines had a secure method to receive encrypted radio traffic. One of the functions of the "off crew" was to collect and send Family Grams. These were fifteen word "letters" including the name of the addressee and originator, permitting only 13 words of text. It was remarkable to see the exercise of ingenuity applied in saying so much in so few words. I would like to share with you the four letters or FAMILY GRAMS that I received during a patrol.
