Comments from Chuck CWO3 C. J. Harrod[Here are examples of just how secret things were around there. ]
Except for borrowing their crane for engine changes, we acted like they weren't there.
We were in pistol range which makes them pretty close. I got to board one when it was on its way to a LSD for transport to Subic.
Seems a temporary plug in the underwater exhaust line came out and she was sinking. The pusher boat coxswain wasn't going to let me aboard until he realized he had never seen the P250 pump he borrowed from me, and didn't have the foggiest how to operate it. Ironically, I had a Top Secret Clearance, but not a "need to know". Consequently, your web-site is very interesting to me. And has answered a lot of old questions.
Some of the boats I saw leave had all American crews on it. Or their are tall blonde Vietnamese out there somewhere. Would like to be kept posted, if not to much trouble.
