The First IJN

Carrier Scored


The USS Trout’s fifth war patrol spanned forty-seven days and was conducted in the Caroline Islands area, off Truk Atoll. The patrol was made in conjunction with her transfer from the operational control of ComSubPac to that of ComSubsSoWesPac. She also departed Pearl Harbor with a new Captain, LCDR Lawson P. “Red” Ramage, in command. On the afternoon September 28, 1942, at the geographic position 06°-59′ N, 151°-45′ E, Trout crossed paths with a IJN carrier group made up of a escort aircraft carrier, two cruisers, and two destroyers. Ramage closed the range to 1,500 yards and fired a spread of five torpedoes at the carrier. Ramage heard two timed explosions, the carrier’s screws stop, and observed smoke rising from its starboard side near the water line. As the destroyers closed on Trout, Ramage took her to 200 feet and successfully evaded a string of ten depth charges. The carrier was the 17,830-ton CVE Taiyo. Taiyo’s TROM indicates it left Davao for Truk on September 22, 1942, and was hit in its stern by one of Trout’s torpedoes. The explosion killed thirteen crew men. On September 29, Taiyo received temporary repairs at Truk by the repair ship Akashi, and on October 4 left Truk for Japan. The CVE arrived at Kure on October 13, where it stayed in drydock for repairs until October 26. It was the first hit scored by any U. S. submarine on a Japanese aircraft carrier. Trout was also credited for sinking the 863-ton converted netlayer Koei Maru during her fifth war patrol.
