I'm pretty sure we see the launchers being unloaded from the shuttles along with the torpedoes themselves.
How sure are you?
Proof?
Even if I'm wrong, Scotty's protest was about how the weapons were being used, not that the ship was heavily armed.
Scotty started protesting before he even knew what the mission was. His objection "I thought we were explorers" was tied to his objection to the
mere existence of these torpedoes on this ship.
Seeing as how the primary hull is covered with phaser turrets and that the secondary hull is dotted with torpedo tubes, you'd think he'd catch a clue.
The TOS Enterprise supposedly had the ability to raze an entire world, after all.
Well, we knew that the ship was powerful enough to destroy species and civilizations. She was powerful enough to be a life killer, but not a planet killer (like the Doomsday Machine).
Moreover, in TOS the idea was that humanity was simply now so powerful where even an exploration ship had this sort of capability. But in TOS we only see phasers and torpedoes ever come from but one place, suggesting that the majority of the mass/structure of the ship is dedicated to other purposes.
In nuTrek the Enterprise is bristling with turrets and torpedo tubes. A good deal of her surface are is
pointed out to the audience to be weapons-oriented.
Beyond this, because this is fiction, we have to consider the visual grammar and tropes being used. To show the side of a ship covered with ports evokes images of fighting ships. All those phaser turrets are reminiscent of battle ships, machine gun turrets on bombers, and so on. The visual message is clear, she's a war machine.
This whole "72 launchers is too many!!!1!" thing is basically assuming two (from classic Enterprises) is the "correct" number.
Two or one was always sufficient for the old ship. It seems the new ship has... ...issues.
I always said if the TOS or classic movie Enterprises ever needed extra torpedo launchers that hatches would open on the hull exposing as many as needed.
Well, it's great that you said it, but that doesn't make it true, does it?
EDIT: It's a series of tubes...
Someone said:
18 tubes, 4 torpedoes each, 9 each side.
Unless someone analysed the screencap and counted 72 tubes, I think the hull showed a lot fewer than that along it.
When Sulu threatens Khan we see at least 5 tubes in a checkerboard pattern. If there are as many tubes on the other side, that makes ten. But this is not all the visual evidence we have. In the infographic that accompanies the line "I see your 72 torpedoes are still in their tubes," it appears that there are at least 12 tube per side and we should not forget about the torpedo tube(s?) sitting at the bottom of the neck which connects the primary hull to the secondary hull. At the very least, by a conservative count, she's 25-gunner, which is more than 12 times as many torpedo tubes as we ever saw in TOS or the TMP-era Enterprise. It could be as many as 72--at least, my screen capture is not really clear on this point.
Doesn't really matter, dialogue trumps effects work, because effects work is more subjective (e.g., we are not given a clear view of all the ports, the infographics are unclear, there are often continuity problems with SFX and on-screen dialogue--how big is a Bird of Prey?). Khan says that 72 torpedoes are in their tubes, then we must conclude that there at least are 72 tubes for torpedoes to occupy on the U.S.S. Enterprise.
