This rule of thumb is good for SH3-4-5.
Hopefully Mark will provide more information.
I think I might test out a new career with a S18 boat and see what happens.
On past experiences using these mods I do not think the problem is there but it will be interesting to see.

i looked into all of the UPCUnitsData files and found no reference to Mk14 and S-18.
in the S-18 Submarine folder i checked out the NSS_s18.UPC file and it looks normal.

[UserPlayerUnit 1.Compartment 4.WeaponSlot 1]
ID= TorpMountB1
NameDisplayable= Torpedo Tube 1
Type=NULL
AcceptedTypes= TorpedoTube
UserCustomizable=No
IDLinkBunker=BowTorpedoRoom
IDLinkWeaponIntervalDefault1= NULL, NULL, TorpedoTube21inOldUS, Mk10Torpedo
ExternalNodeName3D= NULL
ExternalObjectName3D= NSS_S18_Door02_FRU_anim01
ExternalDamageZoneTypeID3D= 58

Activeuserplayerunits.UPC looks normal:

[UserPlayerUnit 1.Compartment 4.WeaponSlot 1.Weapon]
ID=TorpedoTube21inOldUS
NameDisplayable=21" Torpedo Tube
WeaponInterval=1900-01-01, 1999-12-31
WeaponSlotType=TorpedoTube
AmmoTypesAccepted=Mk10Torpedo
AmmoTypeLoaded=Mk10TorpUS

i noticed in the section above that the Mk10 is defined as an "OLD" US torpedo. in Weapons.UPC, the Mk10 is defined in two weapon types, Weapon 8 (21 inch) and Weapon 11 (OLD). However, the Mk14 is right where it should be with Weapon 8.

so, where else does one look to find the link between a sub and its eligible torpedos?
