SH3: sinking times, C2 Cargo and 2 torpedo

[Sailor Steve]

Ever since the game came out the C2 has been noted for the damage it takes to put it down. Here are a couple of threads from way back when discussing the same thing:

It's my understanding that the major supermods, especially GWX and NYGM, go a long way toward fixing this, but using the Merchant Fleet Mod helps the most simply by giving so many more ships to target and reducing the chance of meeting any one type.

If you're playing SH3 unmodded you need to fix that first.

A fun story to go with this just a few days ago.

In the Atlantic...

Small passenger/cargo merchant leading a small merchant, no escort...1941.

Late afternoon. Track them on the surface for some time, get ahead of them by near sundown for a submerged attack. Time the lead ship (the passenger cargo) several times as it goes by me to check my work. Use that speed for an attack on the trailing ship: the small merchant.

Hit it with one torpedo and eventually it sinks. The passenger/cargo is going off into the distance...
Catch up to it an hour later. One torpedo dead-center. It doesn't sink.
Catch up with it again a half-hour later. 1 torpedo misses to the stern. Quick followup without checking my work, next torpedo hits the tip of the bow.

Damaged but still doesn't sink. 3 torpedoes invested in this one ship. Surface...now nighttime. Pace it a while... it sees me, opens fire (later found out it was a twin 40mm on the stern). The previous ship was unarmed.

Crash dive, get back up to periscope depth. Get some distance. Catch up, with it on the surface. It is now zig-zagging. Next torpedo fails. Next torpedo, they see the wake, on a zig and keep going in their turn. Miss. Burn up the battery a bit to cut it off. One electric torpedo: hit... and sinks.

Grand total for two ships: 4444 tons.

At least in your case, you were hitting the target.

Sometimes it happens in real life:

USS Whale (SS-239), second war patrol, January 17, 1943, Lt. Cmdr. John B. Azer.

Fired three torpedoes. Three hits. One hit aft of his stack, the second blew wreckage up through forward hold and the third hit aft. Target started turning toward us. Swung hard right and set up for a stern shot.

Fired single stern shot at range of 600 yards. Hit aft. This was a good hit, stopping the target cold. The target was sinking by the stern, taking considerable port list. Took pictures, firmly convinced this was the graveyard of another Japanese ship. Many of the crew had an opportunity to view the sinking ship through the periscope. Having worked up to windward to observe target better, was astonished to find the fire under control and the list corrected. Water was being pumped over the side through portable hoses.

Fired another torpedo from the stern tube, but this missed. Target was dead in the water, shooting wildly with deck guns.

Crew and passengers abandoned ship, although gun crew remained at posts. Target settled about ten feet overall and then
maintained its depth. Closed and fired sixth torpedo from bow tubes. This hit aft of superstructure depth.

Target still floating. Fired seventh torpedo from bow tubes. This hit with terrific concussion, but did not change trim or draft appreciably.

Fired eighth torpedo from stern tubes. This was heard to hit, but very little concussion was felt.

Getting dark. Target sinking slowly on an even keel, but still looks salvageable. There was no sign of life aboard, although it was believed gun crews had not yet abandoned ship. Wishing to dispose of it before arrival of planes or rescue ships, fired ninth torpedo. This hit right under stack and the explosion ripped away both sides of vessel about ten feet below the main deck.

Target now settled more rapidly, the main deck being a few feet from wash condition at last observation. This vessel had absorbed seven and possibly eight torpedo hits. The cargo must have been of such nature as to prevent her from sinking more rapidly. Target was identified as the Heiyou Maru, 9,815 tons.

On retiring we found ourselves in the midst of eight boats full of survivors, approximately fifty men to each boat. These men were dressed in both white and blue uniforms. One boat was passed close aboard, and survivors made ready to hit the periscope with their oars.
