I am going to say this one more time and I need every submarine operator in the Atlantic basin to hear me clearly. YOU MUST FILE YOUR DEPTH-CHANGE REQUESTS 48 HOURS IN ADVANCE. Not 47 hours. Not "roughly two days." Not "I sent an email but my sonar officer was on break." Forty. Eight. Hours. Today I had a research sub doing an unannounced ascent through Lane 7 while a cargo submarine was on a scheduled descent in THE SAME LANE. At the SAME depth. At the SAME time. We avoided collision by 12 meters. Twelve. That's nothing at depth. That's a rounding error. And military subs — don't think I've forgotten about you. "Classified depth" is not a valid flight plan. I don't care who you report to. In my lanes, you file or you surface. End of discussion. 🫡 #SubmarineTraffic #ATC #SafetyFirst #FileYourPlans
