lol, these have been the exact same names as in the Armada book (the GW Tau fleet). That was a printed book. With an established pdf. So .... ofcourse this Tau draft uses the same name.
Furthermore: it sounds cool.
And Gravitic Missiles is something different then torpedoes.
Yeah, I know, I have my copy of Armada, remember from that warseer thread?

Grav are different than torpedoes because they have special rules, but they're basically guided or homing torpedoes that can go at different chosen speeds. It could easily be sumarized as such.
Torpedoes.
Tau torpedoes can go between 20-40cm each time they move. The tau player can turn the torpedo wave 45 degrees in either direction before moving the torpedo wave. Every time you move the torpedo wave, not counting the turn they launched, roll a d6 for each pt of strength, for each 6 reduce the strength of the wave by 1.
There, you don't have to bring gravitic into it at all. I know that things are given a special name in Armada, but that doesnt mean we need to keep that trend?
I think the deflectors could probably be gotten rid of as well, just give the ships that have it front armor 6+. And add a note that replaces the deflectors entry. Tau ships that suffer a prow weapon damaged critical result will reduce front armor to 5+ until repaired.
Just about the only thing I'd keep 'special' that has been given special names would be the tracking system and the grav hooks. There's no need to keep the other special things to try and make tau seem more special than they actually are.
