Gear around the waist was an inflatable boat being tested.

@USN_Submariner I've often wondered if that's even still a thing.

@SSNBubblehead Still is, but not nearly as deep. Now about a 40' pool instead of a 100' tower.

@USN_Submariner I am a veteran Indian Naval submariner. You kindled nostalgic memories of my training days in 1982. Through the pressure chamber, torpedo tube and up the 30 mts tower... WOW. Given half a chance at the present age of 66 , I would like to do it time and again... Thanks.

@YesyemkayShnan That’s great! I feel the same, would love to go on patrol one more time.

@USN_Submariner Ho ho ho. Ho ho ho…

@USN_Submariner "Ho, ho, ho, ho, ho, ho, ho, ho..."

@USN_Submariner Loved the dolphin!

@USN_Submariner One of the coolest things I ever did

@USN_Submariner @ColdWarPod Inspired by your tweet

@USN_Submariner Here's the trainer in Pearl. After Escape Training in Sub School in '75, I was made to do it again in '77 by SSBN-611G. Don't know why. When it's about escaping from a sunken sub, I'm not likely to forget the first lesson. However, I'll take Hawaii anytime over Groton in FEB.

@USN_Submariner It was my favorite day of Sub School

@USN_Submariner Did my escape training at the BUD/S dive tower on Coronado a year after I qualified. Bunch of SEALs were safety supervisors.

@USN_Submariner Breath out and sing God save the Queen on your way up. Don't do it anymore across the pond here because of health and safety but was an experience back in the day!

@USN_Submariner The only time divers could get the better of us. They used to love to claim that we weren’t breathing out, gave them a excuse to punch us in the gut to force the air out.😂😂

@USN_Submariner I actually miss doing the escape training!

@USN_Submariner 1973 and 1978 (Sub Base Groton).

@USN_Submariner What memories. I’d almost forgot this.

@USN_Submariner Never got to do this as the tank was in Refurb when there. 🙁
