Have you tried a cloak enhancement? Most of the vessels that have a cloak installed most times require the additional benefit of an enhancement. Or, you might ty the Cyclops S frame. It's cloak is a little more steady/reliable.

tried enhancing it to no effect the cloak shows 0 hp 0 everything hitting the cloak button turns it on for a split second before it instantly shuts off

tried googling the problem to no luck

Ok, I talked to our lead programmer and he said that currently there is an issue with cloak times on that ship. Thank you for pointing it out, because we were not aware of that and now that we know, it will be fixed in the next update.

If we are talking about this ship:

I hope that answers it.

Unfortunately, this necropost is relevant, because the cloak on this boat is still broken--it still deactivates as soon as it finishes activating. I didn't check to see if it was because the cloak was stuck at 0 hp before selling the thing.

It's not the most obvious or important bug, given how hard it is to get a Ra'Qaan early game (and how relatively low its usefulness is if you do manage to capture one early or mid-late game, due to its single forward gun with a terrible firing arc), but it's still around. In case anyone was wondering. I'm not holding my breath for a patch, and no mod currently exists to fix the issue either.

I'm the idiot who went and captured one as a level 4 engineer in a Taurus just to see if I could. It made capturing a Luna (which is much better and has a silly number of troopers for a gunship, though its firing arcs are still rubbish) in a gunship possible, so at least there was that.
