I'm finally posting something about this. since i started playing and since I've been using science officers. the photonic fleet and even on all characters the fleet support do not work properly and never have. you activate them and they have a 4 in 5 chance of not shooting and disappearing when your in the middle off a massive group of enemy ships....and its been like this since i started playing
Both of these abilities require you to be under fire for them to work effectively. They won't work against enemies that aren't shooting you, have stopped shooting you or have been destroyed. These work perfectly fine in PvP where you are usually being shot at most of the time.
I've experienced something similar with Photonic Fleet III however, it may be working as intended. Remember these are relatively weak ships they are not 'real', it is possible they are being 1 shot-ed if you are using them in a mob situation. As an experiment, try deploying when you are on a patrol mission, and down to your last enemy.
The first time we see first see photonic ships is in Voyager Basics, part 1, if I'm not mistaken, and they were more of a distraction to the Khazon, than an actual threat.
as true as that is my fleet support and my photonic fleet has done this over 6 times today alone siince ive been on. and msot of them were in mirror event and the typ of character i have i get agro alot im sitting there dieing. and under alot of fire./ and they vanished instead of help.

They do not distribute their shields and have next to no hull, so they probably are dying in massive group. Explosions tend to kill them off regardless as well.
