I'm asking if the (enemy) pilot''s eyes are well protected against laser light beam.
If not, an F-22 or F-35 equipped with DIRCM could blink every pilot in a dogfight.

Well.. I wouldn't know about the protection, but it sounds like it would be hard to shine a laser miles away and hit a target the size of a human eye. A ballistic missile? Sure... and eye in a moving cockpit? I don't think so.

I would hope the eyes would be protected. I know and I've certainly read about police forces taking the threat of handheld laser pen beams to their chopper pilots very seriously so I imagine airforces would take the threat seriously too.
I doubt we'd (as in western nations) use the systems to purpousfully blind the opponent though as such devices are outlawed as far as i know by some convention.
I remember reading a few tales about this system http://www.fas.org/man/dod-101/sys/land/stingray.htm
burning iraqi tank crews eyes out as they looked through their gun sights but i guess thats BS, certainly according to the link its BS anyway. Perhaps it was just a theory that it'd burn or pop eyeballs??

I'm not convinced it is so tough to do. Consider that many many police helicopter pilots have been successfully harrassed by simple handheld laser pens/pointers that are aimed by nothing more than human judgement.
A dedicated system designed to target a small area (like a cockpit) from many miles away sounds feasable to me, especially when you consider how accurately an laser designator pod can be even from many thousands of metres in the air.

And thats just from handheld pointers...

It would be very easy to do from a targeting point of view. Note that ABM lasers don't just hit the general area of a ballistic missile, they need to hit a precise spot on a target and *hold* the beam on that spot for multiple seconds.

The use of blinding laser weapons with the designed purpose of being employed against unaided human vision in combat is prohibited by the UN CCW convention. "Collateral" damage from laser weaponry intended to target optics systems is not covered in that treaty however.

C'mon guy.. in a dog-fight the purpose is to KILL the other pilot... Kill, terminate, destroy.. !!

It's more realistic to me think that any air force implements some protection against it.

Its a facsinating subject this though i'm not sure its in the right forum section here, anyway:

I find this plausable and imagine it did happen. Seems as if weapons conventions only apply to us fools in the west...

Current targeting pods are eye dangerous to several dozen kilometers when using full combat power. It's nice to know exact range of an incoming enemy fighter by constantly lasing it, eh?

Every F-35 pilot will wear the same Gen II HMD. The lens of the visor is made of strong polycarbonate for impact protection. Pilots will also be able to wear one of two outer visors: a darker, sun-screening visor for a bright day or one with protection against laser eye damage.

Offensive and defensive weapons attacking the human eye have been around for awhile. The Royal Navy used ship-mounted weapons to blind attacking Argentine pilots during the Falklands / Malvinas War. The Russian Army used weapons mounted on tracked vehicles to blind Afghan personnel during the Russian occupation of Afghanistan. The technologies and capabilities of anti-ocular weapons have advanced considerably since then.

Pshaw on all this hi-tech laser wizardry.

If you really want to attack your opponent's eyes, all you have to do is project a giant image of Rosie O'Donnell in a thong.

Game, set, match. Cool

Ohhhh duuuuude. Talk about war crimes violations.

No kidding. Twisted Evil

Speaking of, am I understanding this correctly? The UN CCW prohibits the use of lasers to blind an opponent (because it's what, too "barbarous??"), but sending a slammer up his (ahem) "tailpipe" is perfectly hunky-dory?? Blinding lasers are a no-no, but small arms fire is okay? Sharpnel from a grenade?...

Someone please explain the logic here, coz I sure as hell don't get it. I can think of scenarios where laser blinding could be used to thwart (with precision) an attacker and likely even spare civilian lives where conventional weaponry may not be as effective and/or would cause significani collateral damage.

Some of these wartime ROE's are a joke. Frankly, I'm surprised the UN hasn't outlawed VLO aircraft for wielding too unfair an advantage. Rolling Eyes

I think the problem is it's REALLY easy to set up something that will mass blind thousands of soldiers, much easier than actually having to hit all of em with actual ordnance.

The wording of the rule makes it "OK", as Mechanic said, to 'collaterally' blind someone with a ranging laser. But deploying an AN/PEQ-1 Mass Eyeball Cooker is not OK according to that treaty. I'm sure when the treaty was set up it was intended between nations (NATO vs. Warsaw Pact), we didn't imagine going up against a bunch of religious extremist nutballs.

I'm with Mechanic on this one. The laser in an Apache's TADS/MTADS will cause irreversible eye damage at distance. I imagine the lasers in LANTIRN, SNIPER, and LITENING (and all the others) targeting pods are the same class and can do the same damage. These laser beams aren't like the ones on the end of guns and rifles or pointing devices. Their width can be measured in feet. They're not tiny little laser beams. Here's the only decent demo I can find showing how big some targeting lasers actually are: start watching at 2:06

Looking at the beam compared to the 5" rocket will give an idea of how big the beam is.

The further out the beam goes, the wider its radius becomes. Sounds like a calculus word problem. Rolling Eyes

I'd say as long as an aircraft has a targeting pod it has the capability to harass the opposing pilot. Overall, I think I'd rather fire AMRAAMs and Sidewinders at the eye balls of enemy aircrew than lasers. Then again, if we can vaporize the whole entire plane with a laser, I'm all for it. Very Happy
