It seems to target your primary target. I have not noticed any agro increase since starting to use it.

Judging by the animation, anyway, it fires where your primary target was when you hit spacebar. If your target is a fast-mover, you at least get the appearance of your cutting beam's long firing cycle going out into open space.
Also, it's completely useless unless you target somehing with a facing shield down.
The Kinetic Cutting Beam Array MkXII [Dmg]x3 does not drain AUX power it (as other weapons do) utilizes WEAPON power (10 if i remember correctly), Locks on your current target, Is a 360 deg firing weapon (much like a turret but with more Damage and DPS), and in my opinion (for PvErs) is a suitable replacement for a torpedo, I like it! When it hits a target it can deal up to 1.5-1.7k damage (with maximum weapon power)

it's an excelent replacment for a turret or a beam array aft
it's boosted by Wpower EPTW and anything that boost all damage (think APA and APO)
Keep in mind it deals kinetic damage so shields reduce it to a laugable level, but most STF targets are unshielded or have shields only for a short time so that's less of an issue
Also keep in mind the proc bonus with the console or the borg torp
