Sir, that is a genius thought! Probe missiles... could give exploration and scouting and whatnot a solid base to start with.
The question is; could that be possible? Judging from the video, you can look at everything with that modification, so it seems to be a global change, so everybody could "scout" anything with it. There should be testing done, and the modders would need to look at how this was done, mainly because to see if it can be trimmed down to a "scout missile only" or not. I have no experience with the camera options other than ship cam position in the game, and never could be bothered to look closer, so I dunno how that is done.
As with stealthed ships: There are ways to balance them, and there are ways to restrict them to justify balance. There would also be tremendous ways to counter them, and cloaked ships would be certainly vulnerable, possibilities are huge. Other than balancing, I do not understand why cloaking devices are not implemented in the mod, because isn't it considered an expansion to the original Freelancer with all its content. There were cloaking devices so... the only reason I can think of not having them ingame, is for balancing.
So, if I think out loud; "if we can come up with convincing and decently balanced concepts for cloaking devices, would they be finally added to the Mod?"
But back to the radar jammer; the ship itself can be shot, damaged and spotted with the bare eye, the only term would be to balance and / or restrict it that much, so that it makes sense. I can think about certain small shipclasses only, with minor combat capabilities, to justify the amount of energy and signature emitting that a "jamming device". So, if fleshed out, I could imagine it to be well balanced, and a noteworthy addition?
