Description
During the late 1970s, a final and ultimate modernization of the Su-17M fighter-bomber was ordered. The aircraft was upgraded with RSDN navigation, Klyon-57 laser targeting system, SPO-15LE RWR system, the IT-23M optical targeting system for the TUBUS-3 seeker on the Kh-29T missile, and the ability to use the BA-58 targeting system for anti-radiation missiles. The only way to externally distinguish the Su-17M4 over its predecessor, the Su-17M3, is by the presence of multiple extra bleed-air intakes in the rear fuselage, the most noticable one being at the base of the vertical stabilizer. The aircraft would first fly in 1980 and quickly enter service shortly after, supplementing the Su-17M3 fleet throughout the '80s and early '90s, when it was finally withdrawn from Russian service shortly after the dissolution of the USSR. At least one Su-17M4 remains in private service today with Sukhoi, performing the peaceful role of a camera chase plane.
The Su-17M4, introduced in Update "Danger Zone", is the final culmination of the Su-7/Su-17 "Fitter" family of fighter-bombers. The Su-17M4 is a later model of the family, which when compared to the previous Su-17M2, is a major upgrade in almost every way. From the upgraded engine, airframe, and air-to-air missile selection enabling it to perform in dedicated air battles like its predecessor never could, to the major upgrades in ground ordnance allowing it to rain hell from above in mixed battles, all supplemented by the cherry on top: 250+ countermeasures and an upgraded SPO-15LE RWR greatly boosting its survivability in either game mode. The Su-17M4 "Fighter-bomber" is not as great for CAS as its MiG-27 swing wing brother, nor is it as great at dogfighting as well as its MiG-23 cousin. But it performs at a very nice equilibrium of both, allowing it to perform well in either role utilizing hit and run tactics with its large quantity of ground ordnance and generous amount of all-aspect R-60M air to air missiles at the same time.

Compared to the Su-17M2, the Su-17M4 has a few new toys to play with. It has access to two new types of rockets shared by the Su-25. The S-25O heavy rockets are massive, single-shot bunker busters that put the returning S-24s to shame, but only 2 can be carried on the outboard hardpoints, which is a much lower capacity than the Frogfoot's capacity of 8. The S-13OFs are podded HE rockets that can be mounted on the same pylons as the other rocket pods, very effective against light vehicles and sometimes even against armoured targets.
Several new types of guided weapons are available. The Kh-25ML is an improved, extended range variant of the original Kh-25 laser-guided AGM. The S-25L is a laser-guided variant of the S-25 rocket but unfortunately it loses much of its explosive yield. The Kh-29L is a heavy laser-guided AGM with a massive warhead and the Kh-29T is a TV-guided variant. The Kh-29T is the Su-17M4's most important precision weapon: it packs an enormous punch, is fire-and-forget, and most importantly has decent optics and tracking capabilities. Because the Su-17M4 still lacks a built-in TV camera or tracking system like the Su-25T or MiG-27K, it is incapable of using laser-guided weapons to their full potential.
The Kh-23M MCLOS missiles have been removed from the arsenal, but such weapons are largely outdated at the Su-17M4's rank and battle rating.
In terms of air-to-air armament, the main boon is the addition of R-60MK all-aspect IR missiles, which completely replace the original R-60s. Up to 6 can be carried, which is an impressive capacity for a fighter-bomber. Another bonus is that they do not use the same pylons as the guided ordnance, and two pylons are specifically reserved for them. So unlike the contemporary MiG-27M, the Su-17M4 can be prepared for air combat at all times.
Usage in battles
In air battles, the Su-17M4 will suffer against most targets it comes across as the plane itself is an attacker. You are not manoeuvrable and engaging in dogfights is strongly discouraged. Due to the presence of radar missiles, the best way to play the plane in RB is to be a support fighter, trying to stay away from the action before coming in either from the side or on top of a furball/enemy while everyone is distracted, using your R-60Ms to your advantage. Your RWR will be useful and if you do receive a radar lock, it is best to notch and/or try to run away from the enemy, hoping to deter him from attacking you. Head-on attacks are usually not advised as while the R-60Ms are all aspect, they can be easily flared, and it's better to keep them for a more useful situation, unless it's a last ditch effort. Bombing bases can be done but flying directly straight in to the map is risky. On bigger maps such as EC matches, it may be a good idea to take some ground ordnance, and hit ground targets to bleed the enemy tickets, as being a pure "fighter" will usually end in a bad situation.
Ground RB
The Su-17M4 invites comparison to its Mikoyan counterpart, the MiG-27M. Both are swing-wing fighter-bombers with comparable flight performances and arsenals at the same battle rating in Realistic Battles. The Sukhoi's main advantage is that it can carry R-60Ms at all times and has access to lethal S-13OF and S-25O rockets. In contrast, the MiG has to abandon all AAMs if it wants to carry Kh-29Ts, and the remaining hardpoints can only be used for unguided ordnance. The Flogger's can uniquely carry TV-guided bombs for high-altitude standoff bombing against spawn points or capture zones, and boasts an extremely powerful internal cannon, but the Su-17 is a better generalist aircraft for opportunistic tank-busting and combat air patrol.
Another comparison is to the Su-25, another Sukhoi product but a very different aircraft at a lower battle rating. The Frogfoot is a subsonic aircraft with significantly inferior speed, but it also has plenty of reinforced hardpoints and can carry a lot more S-25O and S-13OF rockets, so it is a better and more easily attainable rocket truck for low-altitude surprise attacks. The Fitter's main advantage is in having Kh-29T TV-guided missiles and superior flight performance for competent long-range attacks, which is important when there are enemy SAM systems around.
In general, the Su-17M4 is a jack-of-all trades fighter-bomber. Although it can't keep up with the MiG-27K's ability to annihilate vehicles in infamous high-altitude "orbital strikes", or the Su-25T's ability to repeatedly wipe out an enemy team with high-capacity Vikhrs when the airspace is favorable, the combination of good flight performance and a big capacity of R-60Ms is a strong advantage when enemy jets, helicopters, and strike drones may be around. A loadout of 2x Kh-29T, 6x R-60M, and two S-25O or S-13OF pods is enough to dish out a lot of pain on ground targets and give enemy attackers something to worry about in the low-altitude environment of Ground RB — just remember that as in Air RB, it is unwise to tackle contemporary fighters directly if they have superior agility or long-range weapons.

Pros and cons
Pros:
- Good overall turn rate and energy retention, can hold 800-1,000 km/h in turns with wings fully un-swept and afterburner deployed
- Strong elevator authority, can pull out of low-skimming attack runs with no problem
- Very large amount of countermeasures: 256 x small and 12 x large countermeasures is more than enough to keep missiles off of you
- NR-30 cannons are very powerful, can also mount up to 4 x GSh-23L gunpods for extra burst mass
- Excellent loadout options for both AAMs and ground ordnance alike
- Can act as a very strong supporting fighter with 6 x R-60M AAMs and sweep wing
Cons:
- Roll rate and overall manoeuvrability are poor at speeds below 500 km/h
- With wings fully swept-forward, the maximum speed is limited to approximately Mach 0.8 at sea level otherwise the wings will rip
- No semi-automatic option for managing wing-sweep, only full-manual or automatic wing-sweep settings
- Gigantic target when wings are unswept
- Payload is somewhat low, at only 4,000 kg of bombs
- Cannot carry GBUs or R-13 AAMs like the MiG-27s
History
Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
