What is EOTS & DAS range? Is different in different sides? At front is longer than at back, left or down?

Classified info. Nobody will answer.

pfo and all '1st time' posters on any relevant forum... it's probably smarter to first introduce yourself or at least give some of your opinions on other topics threads, before jumping right into a pretty obviously sensitive question. Sorry to be blunt if you are just an innocent kid out there with a well-intentioned, curious question.. No offense intended.

If you are interested however, there are some PowerPoint advertisements on the net depicting rough sensor ranges for both radar and passive.

You are way too nice geogen, I had a whole slew of smartass answers ready to go! Mr. Green

No range data (as noted why) but plenty of geeky stuff about EOTS and the rest here:

Spaz, the 15 Sep 2005 Program Update and the "LOCKMART has a nice 2 page PDF" have the same hyperlink.

Nice collection.

PFO, when you have the time, I have posted all the program files (2006 forward) on the Program Docs thread.

An idea of the EOTS's performance can be had from looking at it's predecessor, the Sniper XR/Pantera. Public sources mention identification up to 40-50 nautical miles in clear weather, but 'useful range' is considerably more according to Norwegian F-16 pilots:

Update question:
What is DAS range? Beyond visual range?
No info about "DAS range" in google.

EODAS is strictly WVR and no optical zoom.

That wasn't necessarily the impression I'd gotten from some of the presentations, etc.. I've seen.

Well that's just perfect. Doh

No presentation I have seen has ever made the claim of more than WVR, which could be 10 or more miles.

It also depends on what you are using EODAS for. If it's MLD functions, the range is significantly more.

PhilyGuy, What is bad about that?

It seems rather limited in today's battlefield. Are there not equivalent systems already in use which can go beyond WVR and zoom?

You are mixing up EODAS (the SIX IIR cameras that surround the F-35) and EOTS (the FLIR & IRST sensor under the nose).

The EOTS (BVR) has a large lens and optical zoom capability while EODAS (WVR) has a fixed (x6) field of view to continually monitor the battlespace around the aircraft.

While others have the IRST and FLIR (in separate packages) of the EOTS sensor, absolutely NOBODY has the functions of the EODAS.

Oh, I know the difference between the EOTS and the EODAS. My point is that I've seen presentations where the range of the EODAS wasn't limited to WVR- it's just that the EOTS has a significantly longer range.
