If you play the aft torpedo firing scene form "In The Mirror Darkly" over and over you'll see that they come from under the saucer and around the neck. In TOS the torpedoes always fired from either side of the lower sensor dome, so they could easiy also fire rearward from here as they would still miss the neck.
Only Franz Joseph put the torpedo launchers in the front of the command section on top of the bridge and it has stuck in Fandom ever since. A similar thing has started with the Stargazer as some dipictions have the torpedo launchers on the top and bottom of the warp nacelle pylons. If you watch the TNG episode and also happen to have a model, the torpedoes fire from under the forward hangar on the saucer. There are also two seperate undr saucer phaser mounts here as seen firing in the TNG episode "Peak performance".
In the TOS episode "The Doomeday Machine" the Constellation fires from the upper starboard side saucer phaser.
"Aft Phaser Ready!!", is heard over the tannoy on the bridge in many TOS episodes.
Also in the TOS episode "The Balance Of Terror" Kirk yells, "Forward Phaser Room Fire!!" serveral times.
Klingon ships are seen to fire missile drones in the TOS Episode "Errand of Mercy" and reference is made to "Old Mercurite Miissiles" in TNG episodes by Klingon renegades.
ENT plays hamage to SFB by depicting Tholians as spider like cyrstline creatures. Only SFB ever mentioned that Tholians were spider like creatures. Riker also is mentioned to have calculated how to evade a Tholian Dreadnaught, another SFB invention. The Tholians actually only have two dreadnaughts.
I found it odd that the Terran Empire would have only progressed to replicating the Achinar Class Defiance after 100 years but perhaps, to ensure total domination and compliance of the empire, Empress Hoshi reserved the technology solely for her own use, to ensure no challengers to her authority.
It happened in IRAQ with only Saddam's chosen and loyal had proper tanks.
Stalin also did something similar as during 1930 to 1941, the Red Army had the some of the most advanced tanks in the world. However Stalin decreed that only command tanks, and only some would have radios whilst the rest would only have receivers if they were lucky. Many tank to tank communications when the Axis forces invaded was by waving flags only. A single barrage of smoke shells used to screw up command and control in Russian tank units.
Basically if you're the boss of a dictatorship, you make sure that only your closest freinds have the best weapons.
