One more torpedoe question

[MjavTheGray]

Here's the one:
In WC2 Sparks talks to Blair and says 'One more "Ship killer" torpedoe...'.
Then, WC2'ish torpedoes are called 'torpedoes',while missiles do have their names.
Can't remember if WC-III/IV torpedoes had their names or not.
In WCSO they're divided into 'light torpedoes' and just 'torpedoes'. ANd they have names in WCSO.
Also, in Standoff torpedoes are called 'ship killers'.

So - the question:
When did (from the canonical point of view) torpedoes get their names?

I mean - in the roleplay I lead (the beginning of Confed/BW conflict) can my players call torpedoes by names or not?

Before Wing Commander III, torpedoes were given designations similar to those the USN used during World War II - we see the Mark III, Mark IV and Mark V torpedo in Fleet Action. Wing Commander III names its torpedo type - the weapon selection screen identifies it as the 'Lance'. Prophecy has two named torpedoes (Valiant LT and Firestorm T) and so does Secret Ops (Pike LT and Lancer T.) Wing Commander Arena again uses the Lance Torpedo.
