Day 5: First US Submarine Kill Since World War II

On March 4, 2026, a U.S. submarine sinks the IRIS Dena, Iran's most advanced frigate, 40 nautical miles off Sri Lanka. 180 crew were aboard, over 100 remain missing. It is the first American submarine torpedo kill since World War II. Hours later, the Senate votes 47 to 53 to reject a war powers resolution that would have required congressional approval for continued strikes on Iran.This episode tracks five developments that defined Day 5 of the conflict: the destruction of Iran's conventional navy, the failed war powers vote and Senator Fetterman's crossover, a NATO intercept of an Iranian missile heading toward Turkey, Iran's internet dropping to one percent of normal capacity, and the four American soldiers killed in a retaliatory strike on a military facility in Kuwait.Sources for this episode are available at: https://nbn.fm/war-desk/episode/ep68About War DeskWar Desk is an investigative podcast using AI assisted analysis of military intelligence, diplomatic signals, and conflict data to assess global war risk, with sources and references published on our website for verification.Subscribe to NBN's NewsletterGet new investigations, new shows, and the raw intelligence you won't find anywhere else straight to your inbox.Sign up at nbn.fm/newsletter.
