this is based heavily off of JoshuaW's tracker drone thing, I merely added guns and made it able to kill the brown pearl.he did all the heavy lifing.

to find the brown pearl get a very fast jet and fly at a heading of 247 until the message "ye have made a grave mistake" comes up. then chase it until you get within air to ground tracking. once you are close enough that the radar can track it pause the game and create a save location.

Then once you have a save location load the tracker drone. switch to air to ground radar and hit AG1. it can take a little while for it to find it but then it will follow it very close. once you are over top of the vessel start firing the guns like crazy and eventually you will hit it.

Also sometimes it won’t find it and you may need to fire the countermeasures or re spawn
