I met a bunch of NR-1 guys in 1991 while it was in drydock at PNSY in NH. Way cool guys. Our TLD reader broke so we had to use theirs. What a great bunch of guys. I think they are all qualified everything on their sub...like EOOW EWS DV ERS RO SRO SRW ELT all of it. They had a big drape around it so nobody could see the top secret bottom. One of the guys found out moral and conditions on our sub were not good so he immediately asked for an audience with our captain to volunteer to come to our boat as the LELT to make things better. These guys just wouldn't quit. Much respect for NR-1 sailors.
