The Germans and the Japanese used hexanitrodiphenylamine in admixture with TNT in torpedoes, sea mines, depth charges, and bombs. Commercially this explosive was used in compositions called Neurodits. The Swedish used it in compositions called Novit. The Germans mixed it with aluminum powder in compositions called Schieewolle 18, and it was also used in German skip bombs. The Japanese used it in compositions called Seigata (aka Type 97), and Otsu-B.

I read that in her fifth war patrol, Wahoo had both TNT and Torpex warheads on board :
Quote:
0440K; Fired a spread of three torpedoes at tanker identified as
similar to HUZISAN MARU (9,527 tons), range 1,200 yards, 100d port
track, speed 10 knots, and immediately thereafter a spread of three
more torpedoes at the freighter identified as similar to the HAWAII
MARU (9,467 tons), range 1,130 yards 90d port track, speed 10 knots.
All torpedoes were set to run at eighteen feet. Just after the fifth
torpedo was fired the first hit the tanker amidships breaking her
back. She sank by the bow and caught fire aft. The fourth torpedo (a
torpex) hit the freighter under the bridge breaking its back, and the
fifth torpedo (TNT) hit her aft. She sank by the stern. Attempted
taking some periscope pictures in the meager light; then when both
ships had sunk cleared the area to the east.

So I wonder how the SH4 Devs chose the hitpoints ?
