well it depends, if there are several fighters TAGing it and targeting it with lazers and an AWACS to transpond all that targeting data into subspace, then it would probly take somewere in the vasenity of five minutes, if the ravans somehow found a neptune and a direct conflict ensued, it would take about a minute for the ravana to rip it apart, but the ravana would probly be damaged by about 10-40% depending on how far away and if it jumped in in front or behind it. you must remember this isn't a super ship, it is smaller than a standard corvette, it relys on stealth and speed.
a mission it would be great for would be a raid n a cargo depot, it would nock out the capships from subspace then jump in and with fighter escort would begin pushing the cargo into subspace were they would travle to a predefind retreval zone, then submerge back to it's mysterius dark relm.
