What makes a ship unprobeable?

Asked by [ Editor ]

What makes a ship impossible to scan down? And what ships can be set up to do this? Is it still possible to find a ship that is set up this way?

Target size is calculated as sig radius / sensor strength. The smaller your ship's target size, the harder it is for people to probe you down. Below 1.08012498 no one in game can scan you out.

For an unscannable Tengu handy for low/null-sec missioning you'd need:
Gravimetric Backup Array II (low-slot)
ECCM - Gravimetric II x2 (mid-slots)
And nothing that increases sig radius i.e. MWD usage.

(I would have put this in a comment, but they can't be formatted)

Wouldn’t you just fit a cloak, would be a lot easier to stay hidden IMO, and it requires less slots.

fitting a cloak doesn’t allow you to be unprobable while doing other stuff, though.

So long as you’re not being target painted as some one mentioned before you can’t be scanned, this allows you to do low/null sec missions in relative safety. As the mission targets/beacons aren’t scannable.

It also allows you to sit at a safespot with gang links active, boosting your gang safely without fear of being scanned down. A lot less headache when dual boxing.

Zcar300: i was just about to ask the same thing ^^; it make no sense…

Why does your ships sensor strength effect someone else’s ability to scan you down?

serker

Your sensor strength indicates how smart your sensor systems are. The smarter, the less chance it will be fooled by electronic counter methods, such as fake or ot-of-phase signals, check out ECM modules description. I’m not sure which type of waves scan probes use, but it seems logical that your sensors may counter scanning in the same way as ECM modules affect your sensors. With low signature and sophisticated enough sensors, your ship will not allow to scan its location with 100% accuracy, and it actually happens in game – scanning won’t go further than 99% no matter how hard probe will try.

Huh. That tengu fit with nothing else on it……..gives me ~1.60 for the sig rad(150)/sensor strength(93.6)….It must have to do with which subsystems you are using…..hmmm reconfiged and cannot get sensor strength high enough without using 4 ECCM modules…..maybe eft is broken??

Do won forgot to point out that you need Dissolution Sequencer subsystem.

Can this be done in a Proteus, or is it a Tengu-specific trick?

If you get your Sensor Strength higher than your Signature radius (in meters) through the use of ECCM or lowslot modules for example, no pilot can probe you regardless of their skills or equipment. This is not actually possible on many ships and pretty much only on T3 doesn't result in a severely gimped fit. If you are missioning in an unprobeable T3, do not launch drones and be wary of target painters in angel missions as both of these things will make you probeable.

Or you can just cloak.

It’s actually a little more complicated than that. Do Won got it right

rashmika

I don’t think you need to get it higher… isn’t something like 90% sensor strength of your sig radius?

serker

It depends on scan strength of the probes that try to pin you down. ~1.08 number in Do Won’s post makes you unprobeable for everyone, including any sets of skills, ship and implants. It may be not required 100% of the time, but you can’t be sure in your safety with lesser number.

Update: It is no longer possible to be completely unprobeable (JAN 2011). Fits that met the criteria before will still be very difficult to probe out, but it is now possible with high skills and good modules.

So is it your signature radius divided by their sensor strength? Because I can't understand why your ships sensor strength would effect their ability to target you.

ok i guess that make some sense ^^;

Our sensors have some built in ecm… Wow who would have know. I guess in that case it does make sense.

Every active scanning system may serve as a weapon, of sort. Ever thought about what “locking” process indicates? For me it is a combat between your and target’s electronics, where yours try to pin and lock it down and target’s tries to counteract. It will be more realistic if lock may disappear on its own or lose stability if target is nimble and/or have good systems, but it will send balance to hell. And that’s why we have three discrete numbers – sensor strength, sensor resolution and signature radius, to make it rather simple. The same thing as this un-realistic speed limitation in space.

A cloaked ship is completely impossible to find with probes.

A ship parked more than 15AU from a celestial object is probably safe-ish, unless the prober is specifically looking for targets.

Fitting your ship with ECCM modules increases your sensor strength and lightly skilled probe pilots will have difficulty reaching more than 99% lock on you (i.e. no chance to warp to your position.) A skilled pilot, however, with sister's probes and launchers, flying a covert ops, is impossible to hide from using sensor strength increasing modules.

Actually, it is possible to be unscannable. Do Won got it right. There are various reason to do it: (1) on a command ship / T3 to give leadership bonuses. (2) On a T3 to run low/null sec missions in safety. Neither of those things can be done while cloaked.

Off the top of my head:

Off line pilot, with a graceful log off.

In something else (station, hanger, cap ship).

Cloaked.

Too far away--though with combat scanner probe's 64 AU range, I don't see this happening once deep safe BMs are removed.

Range is beatable if you can get in range. Cloak's if the cloak pops for some reason.
