Yep, the old diesel boat reserve fleet was there, but it was mostly on paper due to the danger I illustrated. There were some instances of wet weekends but the boats rarely put to sea. Even the active duty types in the 1970s were hard put to go to sea. I remember an old diddy about a SUBRON in New London (composed of USS Harder, USS Darter, USS Trigger, and USS Trout). It went thusly:
Harder, Darter, Trigger, Trout
Always homebound, never out!
I would encourage all active duty submarine personnel that are not going to make it a career, to seek a slot in the Naval Reserve Submarine force when they get out.
Actually I encourage all veterans that were a notch above, that had a greater interest in their job than their fellow soldier, yet chose to leave the service, join the Guard or Reserves.
