Firstly, you surely mean the isotope of hydrogen which is called Deuterium and secondly,Deutrium? Don't they usually need that for propulsion in the series?) but never mind me do whatever you want I'm just a bit confused in gneral
the propulsion resource in Star Trek is called Dilithium. I would prefer DIL or DL in the GUI.
To the torpedos: there were only Photonic Torpedos for the Federation in Star Trek Enterprise (the NX-01 series) which makes it fine to use PT there, as long as you don't plan to add Romulan/Klingon/whatever ships there.
Season 3 added Photon Torpedos IIRC but PT is fine there too.
/nerd rage off

I like your Photon torpedo sprite and they're fine IP/lore-wise
But honestly I would prefer a Phaser-Beam weapon to the Phaser cannon as a starting weapon with an orange, continuous beam.
:edit: :nerdrage: Finally, the thread has been updated to LCARS and not ICARS Theme. (One thing that bothers me: The NX-01 didn't have LCARS, it was introduced in Enterprise D, which is more than 200 years later lore-wise.)
