I’m a submariner too (USS Flasher SSN-613), and our whole Enginnering crew would go to jail for our deployment pictures between the main propulsion turbines. This is ridiculous.
I was on ss581 and ssbn633, I agree, a pic of what ever room don’t mean nothing. Now passing other interior secrets is different. There are at least 20 countries with subs, a pic of the engine room aint squat.
I’m an older guy and we didn’t have cameras like today but yes I can definitely see 100s of sailors, marines, soldiers and airmen taking pics of themselves in their workplace.
The secrets are in the engineering, research and development of what was developed in that pic.
