USS Sealion attacks and sinks battleship Kongo

The battlecruiser Kongo had been built by the British shipyard Vickers in 1912. In 1929 she was re-bilit as a battleship as seen here in 1929-30.

The original USS Sealion had been sunk by Japanese during their initial assaults on US ships in December 1941. Less than two years later USS Sealion was reborn, launched on 31st October 1943. Exactly a year later she set off on her third war patrol, her commander, Eli Reich, having already been awarded Navy Crosses for “aggressive and well executed torpedo attacks” on each of the two earlier patrols. In September she had been responsible for the unfortunate sinking of the Rakuyo Maru, with 1300 POWs aboard.

Early on 21st November off Formosa, now Taiwan, the USS Sealion picked up such strong radar signals that at first they were thought to be bouncing off land. They were then revealed to be a group of Japanese battleships and battle cruisers, including, as it turned out, the IJN “Indestructible” Kongo.

Commander Eli Reich’s original patrol report tells the whole story:

21 NOVEMBER 1944

0020: Radar contact at 44,000 yards, on our starboard quarter, (Ship contact #3) three pips, very clear and distinct. Came to normal approach, went ahead flank on four engines, and commenced tracking. Overcast sky, no soon, visibility about 1500 yards, calm sea.

0043: Two large pips and two smaller pips now outlined on radar screen at a range of 35,000 yards. These are the greatest ranges we have ever obtained on our radar. Pips so large, at so great a range, we first suspected land. It was possible to lobe switch on the larger targets at 32,000 yards – we now realized we probably had two targets of battleship proportions and two of larger cruiser size as our targets. They were in a column with a cruiser ahead followed by two battleships, and a cruiser astern, course 060 T, speed 16 knots. not zigging.

0146: Three escorts now visible on the radar, at a range of 20,000 yards. One on. either beam on the formation, and one on the starboard far quarter. We are pining bearing slowly but surely. The formation is now on our starboard beam. Seas and wind increasing.

0245: Ahead of task force. Turned in and slowed for attack, keeping our bow pointed at the now destroyer who is now 1800 yards on the port bow of our target. the second ship in column. Able to make out shape of near destroyer from bridge. Kept swinging left with our bow directly on the destroyer, and at

0256: Fired six torpedoes, depth set at 8 feet, at the second ship in column, range 3000 yards, believed to be a battleship. Came right with full rudder to bring the stern tubes to bear.

0259-30: Stopped and fired three torpedoes, depth set at 8 feet, from the stern tubes at the third ship in column (ie the second battleship). Range 3100 yards. Range to near destroyer at the time of firing stern tubes about 1800 yards. While firing stern tubes, O.O.D. reported he could make out outline of the near cruiser on our port quarter. During the firing of the bow tubes the bridge quartermaster reported he could make out outline of a very high superstructure on target, he said it looked to him like the pagoda build of the Jap battleships.

0300: Saw and heard three hits on the first battleship – several small mushrooms of explosions noted in the darkness.

0304: Saw and heard at least one hit on the second battleship – this gave a large violent explosion with a sudden rise of flames at the target, but it quickly subsided.

In fact two torpedoes from the first salvo had hit Kongo and a third torpedo had passed beyond her and hit the destroyer IJN “Wind on the Sea” Urakaze, causing a catastrophic explosion which sunk her with all hands. With two compartments flooded the Kongo began to lose speed.

Eli Reich thought he had lost his opportunity, believing that he had set his torpedoes at the wrong depth for a battleship. His patrol report continues:

0304-07: Went ahead flank, opening to westward from target group. Noted several small explosions, flames, and probably lights in vicinity of target group.

0308: Heard a long series of heavy depth charge explosions from vicinity of enemy force – we are about 5000 yards from group. P.P.I. shows one escort opening and rapidly to east of target group. Continued tracking.

0330: Chagrined at this point to find subsequent tracking enemy group still making 16 knots, still on course 060T. I feel that in setting depth at 8 feet, in order to hit a destroyer if overlapping our main target. I’ve made a bust – looks like we only dented the armor belt on the battleships.

0406: Tracking indicates the target group now zigzagging. We are holding true bearing, maybe gaining a little. Called for maximum speed from engineers – they gave us 25% overload for about thirty minutes, then commenced growling about sparking commutators, hot motors, et al , forced to slow to flank. Sea and wind increasing all the time – now about force 5 or 6 – taking solid water over bridge, with plenty coming down the conning tower hatch. SEALION making about 16.8 to 17 knots with safety tank dry and using low pressure blower often to keep ballast tanks dry. Engine rooms taking much water through main induction.

0430: Sent SEALION Serial Number TWO. [?]

0450: Noted enemy formation breaking up into two groups – one group dropping astern. Now P.P.I. showed:(a) one group up ahead to consist of three large ships in column – cruiser. battleship, cruiser with a destroyer just being lost to radar view up ahead. Range to this group about 17000 yards. (b) Second group dropping astern of first to consist of a battleship, with two destroyers on far side. Close aboard – range to this group about 15000 yards and closing.

0451: Shifted target designation, decided to attack second group, which contains 1 battleship, hit with three torpedoes on our first attack. Tracking shows target to have slowed to 11 knots. Things beginning to took rosy again.

0512: In position ahead of target, slowed and turned in for attack.

0518: Solutions on T.D.C. and plot is getting sour – target must be changing speed.

0520: Plot and T.D.C. report target must be stopped, radar says target pip seems to be getting a little smaller. Range to target now about 17000 yards.

0524: Tremendous explosion dead ahead – sky brilliantly illuminated, it looked like a sunset at midnight, radar reports battleship pip getting smaller – that it has disappeared -leaving only two smaller pips of the destroyers. Destroyers seem to be milling around vicinity of target. Battleship sunk – the sun set.

0525: Total darkness again.

Before Sealion had a chance to make another attack Kongo had blown up. There were just 237 survivors from a crew of over 1400.

Reich had earned a third Navy Cross on his third patrol. Not only was this the only occasion when an Allied submarine successfully sank a battleship during the war but it was the only occasion an audio recording was made of a live attack.

  1. Your well written story is very much like the 1957 television story on The Silent Service, season 1 episode 31 titled The Sealion Story. It is on YouTube for free.

  2. I like the destroyer IJN Urakaze and the fast battleship IJN Kongou, they were superb. But the submarine will always be the new war machine. This hit of the USS Seallion closely resembles the Japanese submarine I-19 that sank the aircraft carrier USS Wasp and the destroyer USS O’Brien and damaged the battleship USS North Carolina. Japan had destroyer ships equipped with extremely sophisticated torpedoes, but a pity they did not value sonar and radar, although there was an adept engineer and the willingness to have built radars even better than the current IJN used. Sad!

    unfortunately the Imperial Japanese Navy ceased to exist, but at least we could say that it was an honor to the Japanese to have lost to a stronger power!

  3. Are there any crew rosters or picture of the crew? My husband’s dad was the periscope operator on the Sealion, and we were hoping there was some photo record of the crew.
