Congratulations to both your son and to you. My father was a submariner in WWII on a Gato Class Sub named the Gurnard (there is now a nuclear sub by the same name). My father stayed with the sub for the duration of it's service until after the end of the war. He was what was then known as a plank owner working in the engine room.
Submariner service holds a very special place in my heart, my father never told many war stories. Much of what I have learned of his service to his country I have learned from his old shipmates that I have sought out through Internet sources.
Please know that you have every right to be proud. Your brave young son and the others in his class will be in my prayers. Thank you.
Thank you for my thoughts about your dad's service see #21.
