You`re comparing two generations of Su-17 aircraft, the Su-22M4(Su-17M4) variant was equipped with the digital CVM-20-22 mission computer and the PrNK-54 weapon system with RSDN navigation (TACAN-equivalent), what reduced pilot workload and improved navigational and weapons delivery accuracy. Not sure whether the more advanced avionics demanded to save space or weight in the nose of the fuselage, but the`ve decided to get rid of the variable nose cone and optimalizing it for high speed, low level penetration. The auxiliary intake doors behind the fixed nose cone are opened inward only.
The Su-22UM-3K double seaters were based on the Su-22M3 single-seat version lacking all that above. The variable nose cone remained from the M3 variant. The auxiliary intake doors on the both sides of nose section are opened outward/inward automatically in response to pressure in the duct. For example above speeds M1.7 the auxiliary doors are opened outward, releasing air pressure within the shock wave inside the duct and with the variable nose cone, it is capable of M2.1.
At last as wrongly assumed by colleague MSphere both single seat Su-17M4 and the double seater UM-3K feature the KLEN-PS laser rangefinder/ designator.

I stand corrected. I have assumed that the window on the UM-3K was only a leftover from the single-seat version to increase commonality of parts and that it served no function, whatsoever
So the variable/fixed nose cone is a thing of M-3 vs M-4 version, not single-seater vs twin-seater?

Thanks, one learns new things everyday.
The shock wave core of Su-17M is fixed? Any provement?
The truth usually between two extremes, the key is when and where.
VELOS relies on continuous wave radar and is vulnerable to modern SEAD tactics and weapons. SAM batteries are most effective when concealed, which CW doesn't allow. Air dropped decoys are commonplace, too, revealing positions of active radars and allowing the dynamic targeting systems to do their thing.
Go Huskers!
When it is misused for surveillance purposes. All serious military operate their items/systems the main threat in mind. By the way most missions are "mapping ones" in preperation to go serious one day. Having "mapped" a general lay-out a just smaller number of missions are in need to monitor changes of that. Just from that moment you are able to make some good use of your own SEAD.
Hardly as they have lacked radar. I personally count the Su-17 more in the Jaguar / MiG-27 class.
India is upgrading their Jaguars by fitting Honeywell turbofan engines which will greatly increase thrust. I cant believe no one has mentioned this.

Does anyone know where this will put the thrust to weight ratio of the Jaguar? Im curious if it will now be 1 to 1.
