1.3.ok.
steam sells just about all versions from 1.0 to 1.5.

ok....i play version 1.5 so i'll answer your question from that POV.
the torpedoes you will have will be the version of Mk14 or Mk10 or whatever depending on the date of the single mission. for example, if your mission is early 1942, you will have the Mk10 (for s-boats) or Mk14 for everyone else with all of the warts that those fish had in early 1942, provided that you have checked the Dud torpedo option in the Gameplay area. i believe you will automatically get the deep runners and prematures but the Duds are an option.
so, if you are playing a 1944 or 1945 mission, the Mk14's will perform much more reliably.

if you intend to play some of the mega-mods, after you get your sea legs, you will need to hunt down version 1.5, aka Silent Hunter: Wolves Of The Pacific - Gold Edition.

virtually all SH4 megas are based on 1.5. it is usually on sale for $10 on Steam or Amazon, sometimes for less.

Subsim has a sales link which, if you click the link, it takes you to Amazon and IF you purchase something in that session, Subsim makes a few pennies.
totally optional.

good luck on your mission. have fun!
