and an estimated range of with a track angle favorable. About two and a half minutes later, crewmen in S-32′s torpedo room heard a muffled explosion, but her fire control control party heard nothing. S-32 went to periscope depth and observed smoke was pouring skyward from the Japanese submarine's conning tower. Her crew took a periscope photograph of the scene as the damaged Japanese submarine headed for the nearest beach. At 17:36, however, the Japanese submarine disappeared from view. S-32′s sound operated reported that the Japanese submarine′s screws had stopped. S-32 departed the Attu area early on the morning of 17 March 1943. On 20 March 1943, she moored at Dutch Harbor. Seventh war patrol On 29 March 1943, S-32 again departed Dutch Harbor and headed west for her seventh war patrol. En route to Attu, cold weather caused icing on her superstructure, but the seas remained fairly calm and the sun was occasionally visible. On 3 April 1943, however, as she approached Attu, more normal Aleutian weather closed in. From then to 16 April 1943, snow and rain storms were almost continuous, seas were rough, winds were strong, and periods of sunlight were limited. At 01:57 on 10 April 1943, while patrolling on a north-south line off Holtz Bay, S-32 picked up a target on radar some away. At 02:07, S-32′s radar detected a second, smaller ship ahead of the first target. At 02:12, S-32 sighted the first ship at a range of about . She launched four torpedoes. Her crew heard two very loud explosions followed by distant rumblings. At 02:19, at a range of just over , all traces of the ships disappeared from S-32′s radar screen. On 16 April 1943, S-32 set a course for Dutch Harbor. On 20 April 1943, she arrived and commenced refit. Eighth war patrol On 4 May 1943, S-32 again sailed west to commence her eighth and final war patrol. En route to the Kurils, she patrolled across possible Japanese reinforcement routes to Kiska and Attu, but almost zero visibility during the passage hindered hunting, an on 11 May 1943 her radar broke down. On 12 May 1943, she entered her assigned area off Paramushiro. On 13 May 1943, she obtained her first navigational fix, off Onekotan, and commenced patrolling across the approaches to Onekotan Strait and Musashi Bay. Visibility remained poor, and seas were rough. Her radar functioned improperly throughout
