We all make mistakes, be it in personal decisions or maybe relationships, even in our jobs. That’s part of us as human beings. At work, there’s this accidentally-sent-an-email-without-the-attachment kind of mistake, and then there’s this I-almost-blew-up-the-President-of-the-United-States mistake. For the US Navy, it’s painfully the second one.

We mess things up sometimes, and in the world of the military, these errors become the perfect means to tease your peers and make sure they never forget what they did. When the USS William D. Porter was brought back to its homeport, it was greeted with a giant, “Don’t shoot, we’re Republicans!” Guess why?

Off to a Not-So-Great Start

In 1943, President Franklin Roosevelt and US Secretary of State Cordell Hull boarded the USS Iowa, together with the top brass of the US military during World War II. They were on a crucial and special mission of meeting their Allied counterparts in Cairo and Tehran. These leaders included British Prime Minister Winston Churchill and the Soviet Union’s dictator, Joseph Stalin.

Sailor are a superstitious lot, and some ships are considered “lucky” and others are considered a jinxed, or Albatrosses, a reference to the “Rhyme of the Ancient Mariner’ poem from the late 1700s.  USS Porter was a hard-luck ship within months of her commissioning. As she was leaving Norfolk to join the Iowa carrying the President, her stern swept the side of another destroyer berthed next to her, smashing the other ship’s lifeboat davits and carrying away her railing. The following day, one of Porter’s depth charges slipped off it rails and detonated so close to the ship that a large wave washed over her stern sweeping a sailor overboard who was not recovered. Thinking the Iowa task force was under attack by a U-boat, the battleship and her other escorts twisted and turned out of formation until the Porter could signal that it was just a depth charge accidentally exploding.

Just a depth charge.

President Roosevelt wanted to see a demonstration of the capabilities of one of America’s newest battleships so the Iowa send a bunch of target balloons aloft and opened up with her anti-aircraft batteries in an awesome display of firepower. Most of the balloons were shot down by the gunners onboard USS Iowa. However, some drifted over to where USS Porter was, and they got to shoot down a few balloons as well. The other escort ships, USS Porter included, were to next demonstrate mock torpedo runs on the USS Iowa while the President watch from the bridge of the battleship. And this is when the Porter was unlucky again. Primers on the torpedo launchers were supposed to be removed to prevent the torpedoes from being fired. As it turns out, one tube was left primed.

Mistakes Were Fired

USS Porter went into position roughly 6,000 yards from Iowa to begin its mock attack. Things went according to plan as the Porter made a flank speed run at the Iowa and then swung her bow to bring her torpedo tube mounts to bear on the target.   Just like a normal drill, the weapons officer keyed the triggers on the launcher for the simulation attack. Then, to his absolute horror he watched Mount #2 launch a live torpedo at the Iowa(and the President aboard) at close range. More than 600lbs of high explosives doing nearly 50 knots were on it way.

Porter’s captain would have been able to warn USS Iowa about the mistake immediately, except orders to maintain strict radio silence were in place to avoid radio detection and location by German U-boats, the USS Porter would have to signal USS Iowa of the incoming torpedo using a signal lamp.
