Re: Loss of Argentine submarine ARA San Juan Cause

During the early 1960's I was a crew member on a diesel electric submarine, we had just completed an overhaul and refit of the main engines. One of the post overhaul events would be the testing of the snorkel system.......while cruising submerged"commence snorkeling" was the word passed......... No.2 main engine began to roll and fired as the inboard exhaust valve was opened, along with able-baker outboard exhaust............with in all of ten seconds sea water was flooding into the engine and roaring out the blower silencer and bringing hydraulic destruction to at least seven cylinders out of sixteen, we took on a pretty big load of sea water and got to the surface. Some how or another, the snorkel exhaust mast seals and packing had been omitted from their intended space during the yard work. Many years later on another diesel electric submarine, the engine room induction piping collapsed causing the boat to become 18,000 lbs. heavy, that combined with loss of ship control and flooding just about caused loss of the ship, as it was, the bow had exceeded twice its design in test depth on the down angle................both instances were note worthy, I can assure you! I also experienced a submerged collision in the 1970's with an uncharted seamount while going deep at ahead full on a nuclear attack submarine, similar to the San Francisco event..............very close! took some major repairs and a ship yard visit....we can speculate as to what caused the loss of the San Juan. A very sad event all around.
