Eurofighter Typhoon (UK versions) - Technical data and discussion (Part 2)

theres a russian brochure somewhere out there that says its effective against iir somewhere… lemme find it

Now that is interesting!

This one?

That would be only possible if it destroys the seeker of the IIR missile as it otherwise would simply switch to HOJ mode. The problem with that: The LDIRCM has to be stabilzed against all maneuvers and vibrations of the carrier plane and additionally exactly target the seeker-head of the incoming missile. To hit a missile seeker head the size of 10 cm at 100 meters (not 1000 meters) the laser has to be directed with a margin of error of ~0,6°, so you have to detect the missile this precise and be able to align the laser too. The precision is mandatory as you not only want to blind but to destroy it so you can’t work with “somehow that direction” but have to go by “exactly that direction” so that most of the energy of the laser is hitting the sensor.

What do russians consider as 3rd generation IR missiles? Can you provide some clarity @_Fantom2451

What is that said missile photographed and aligned with 4th generation?

eh cant te||, scan quality too low

good question, but the mounting looks awfully similar to a f-15 wing pylon

what |aser’s name is that

So that diagram would consider the likes of ASRAAM, MICA-IR, AIM-9X, etc. to be 4th generation?

since those have photodetectors arrays… yes unless im missing something.
the russians did test out photo detector seekerheads at this time even if other people think they didnt have the tech

This diagram kind of trips me up on the “3rd generation” seeker distinction as well, since afaik, the IRIS-T is the only missile using such a seeker, which makes it a bit odd to dedicate a whole “generation” to one missile.

Its also weird when combined with the earlier source since the IRIS-T is directly stated to be highly resistant to blinding lasers, which makes logical sense as well, since one of the primary methods of defeat for IIR seekers vs DIRCM is the use of HOJ via IR intensity gradient tracking. A scanning array would be capable of the same gradient tracking with the added benefit of being able to blank or skip scanning the point of highest intensity, while also taking advantage of much shorter exposure durations.

I guess the theory of scanning arrays being less resistant could be that there is a risk of the scanning element being damaged while tracking a DIRCM laser, but I’d think any engineer worth their salt would leverage adaptive scan blanking to protect the scanning elements from any emissions that might surpass the threshold at which the scanning elements would be damaged to protect said elements.

what was the verdict on the typhoon getting hosbo again?

there wasnt any

Final evolution.
Meanwhile germany with tranche 5 orders xD

Similar upgrade packs all said and done. T2/3 can have anything a T5 could.
