Submarine Command Decision-Making Under Information Uncertainty (warontherocks.com)

• Submarine commanders operate with inherently incomplete information due to physics of sound propagation.
• Decision-making is collective but commander must decide when information is sufficient.
• Five disciplines: protect stealth, separate known from assumed, trust intuition, consider error consequences, delay when consequences uncontrollable.
• Lessons applicable to land, air, and maritime operations in contested electromagnetic spectrum.

"A former Portuguese submarine commander describes how structural uncertainty in the undersea environment demands a disciplined approach to decision-making. He outlines five habits: protect stealth, separate known from assumed, trust intuition without surrender, consider consequences of being wrong, and delay when risks are uncontrollable. These lessons apply to modern contested environments where information is degraded."
