^^ Quite correct. That's why I contacted Harvey
and asked for help. On such a short notice that's what he did find for "The Changeling":
"The de Forest Research memo for "The Changeling" (dated June 6, 1967) does comment on the script's usage of torpedoes several times:
A bolt of extremely powerful energy, Captain. Not unlike a giant photon torpedo. - The meaning of this line is unclear. The implication has been that a photon torpedo is an “object” like a conventional torpedo – that it must be loaded into “tubes” and “armed” and fired. How this could resemble a “bolt of...energy” begs explanation.
Photon torpedoes activated. - Suggest: photon torpedoes armed, to conform with previous usage.
Has the target changed position...No sir... Fire a full spread of torpedoes... – A “spread” of torpedoes is meant to cover a moving target. Since Nomad has not changed position, a “spread” would not be used. Suggest: “salvo” as more accurate word.
The de Forest Research memo (September 22, 1967) for "Journey to Babel" makes no mention of torpedoes, though."
(Thanks a lot, Harvey
What's interesting to read here, IMHO, is that the original screenplay draft apparently envisioned an "energy pod" (The Making of Star Trek)
but de Forest research somehow "discouraged" that idea and advocated a solid or conventional torpedo (and terminology that goes along with that).
Equally interesting is how the TOS producers went along with these suggestions for
- "The Changeling" - KIRK: That's our target, Mister Sulu. Prepare photon torpedo. ... SULU: Photon torpedoes armed, sir. ... KIRK: Ready photon torpedo number two, Mister Sulu.
- "Journey to Babel" - KIRK: Fire.
CHEKOV: Full spread missed, sir. They're moving too fast for us.
- "Elaan of Troyius" - KIRK: Chekov, arm photon torpedoes.
CHEKOV: Photon torpedoes ready. ...
KIRK: ... As he passes, I want to cut in warp drive. We'll pivot at warp two and bring all tubes to bear. ...
KIRK: Mister Chekov, give him a full spread of photon torpedoes.
In simpler language: The photon torpedo apparently transformed from an energy pod / a magnophoton shell into a solid, conventional object that has to be loaded into a tube, armed and fired.
The original question here had been whether the numbering referred to solid torpedoes or to launch tubes.
If you insist we are looking at energy pods instead, then six "launch tubes" would also require six (!) antimatter injectors in that small area (they couldn't even make the coolants for the phasers foolproof in "Balance of Terror"
