The development of the Su-24 marked a new development of Soviet tactical aviation. The qualitative leap took place primarily in the tactical use of this powerful means of fire influence - was made possible fast and stealthy maneuver forces over vast areas with extremely low altitudes and unprepared airfields. Increased power and impact of the aircraft, which is largest bomb and rocket salvo is 2-4 times higher than not only the old Il-28, Su-7 and Yak-28, but the new Su-17M and MiG-27. Nevertheless, still it was the question before the planned use of the range of precision-guided munitions.
The Su-24 built at the turn of the eighties had been finalized for the application of the new anti-radar missiles X-58, which was provided for the suspension stations targeting "Phantasmagoria". At the same time they retained the ability to launch the X-28, and unified aircraft ejection device AKU-58, designed for the suspension of the X-58 and provided with adapters.
Outdated and insufficiently powerful radio-controlled missile X-23M replaced by a new X-25MR, which produced guidance on the same algorithm with the use of equipment "Delta" and "Ram". It was about the same range of start-up, but a more powerful warhead (140 kg against 111) and can be used with extremely low altitudes - up to fifty meters.
Unguided Missiles includes rockets caliber 57, 80, 240 and 266/340 (420) mm with fragmentation warheads, high-explosive fragmentation, cumulative and penetrating, as well as special purpose. Unguided rockets caliber 57 mm are used out of the blocks UB-32A-73, with 32 launchers trunk and presented NAR C-5M, St. 5Mo, S-5K, C-5KO (CP) with a warhead high explosive, high-explosive , cumulative and cumulative-type fragmentation, respectively, specialized lighting rockets (C-5-A) and anti-radiation (P-5P) destination. Unguided rockets caliber 80 mm used in 20-barrel unit B-8M, and can be equipped with shaped-charge fragmentation (NAR C-8, C-8B, C-8A, C-8M) or explosive permeation (S-8B) warheads, flechette (NAR 8VS C, C-8AS).
Heavy rockets C-24 (C-24, B) have a caliber of 240 mm high-explosive fragmentation warhead and are used with aircraft launchers APU-68UM2. Unguided rockets S-25 caliber 266 mm have nadkalibernuyu fragmentation warhead (C-25-A) or high-explosive (C-RP-25) action with a diameter of 420 and 340 mm, respectively, and run from the disposable devices O-25. At the same time a plane can be suspended up to 6 blocks of UB-32 and B-8M, 4 missile C-24 or 6 devices O-25 NAR C-25.
Guided Missiles impact includes tactical guided missiles (SD) of class "air-surface" type X-23 and anti-radar missiles X-28 and X-58. UR X-23 (product of "68") has a radio command guidance system with control commands over the radio "Delta", the equipment is installed on board the aircraft carrier and missiles. Weight rocket is 288 kg, the maximum launch range - 10 km. The missile is equipped with shaped-charge fragmentation high-explosive warhead weighing 111 kg.
The Su-24 was capable of suspension of 4 missiles X-23, the trigger-68UM2 AAP. Guided missiles "air-radar" X-28 (a product "E-8") is a passive radar homing head, weight 715 kg and launch range up to 65 km, equipped with high-explosive warhead weighing 140 kg. UR X-58 (a product "D-7") has the same purpose and guidance system. The missile weighs 640 kg, has an explosive fragmentation warhead weighing 150 kg and launch range up to 70 km. On the plane, it is possible to hang two missiles X-28 (the trigger PU-28), or two X-58 (in aircraft ejection devices such as AKU-58-1).
Guided Missiles class "air-to-air" consists of two missiles R-55 (product of "67") with thermal homing, flown the trigger for turning the moving parts of the wing pylons.
The most difficult part of training was learning the use of weapons. This had to be carried out in several stages, but even then it took to enter the "specialty" - usually in the regiment stood one-two squadrons, and one missile - carriers of nuclear weapons.
The emphasis in the military training of the first was on training with the X-28 ( usually simpler rocket X-23 were able to let all the crews). In flight with the X-28 rocket launch is usually not made (it was quite expensive), and carried out a "tactical start" - included a navigator station "Owl", he showed the radar and all necessary functions in manual mode without the very start. Then on the ground were studied recorder data and draw conclusions about the errors in the work of the crew.
The latter is often practiced bombing conventional bombs, the main burden in the "specialty" fell on a group of armed and navigators who were studying additional routes. Although the pilots had their "tricks" - in particular, have been developed combat maneuvers approach the goal to clear the SBP from low altitudes and safe departure from the targets.
Crews, in addition to its specialization (media "spetsboepripasov" UR antiradar Kh-28 and Kh-23M tactical) practiced assault attack starts Nursi and firing of the guns, but gradually the focus shifts towards the solution of formulated purely bombing tasks.
The basis of aircraft armament was aiming and navigation system PNS-24 "Puma-A." It consisted of: forward-looking radar (RPO) "Orion-A" typical object detection range of 150 km. Radar could devote even low contrast targets against the background of the earth and water, according to its figures could carry all types of Freefall bombing bombs. To defeat radio-emitting objects of the enemy served as a passive radar (CP "Owl") detection of ground radar and target missiles with PRGSN interacts with the first Soviet missile designed specifically for frontline aircraft - the X-28 (D-8, Vol. 93, projected Su-24 missile X-24 (X-58) was not yet ready).
The first production Su-24 had the old station "Owl", interacting with PRGSN -28 missiles X-28 experimental and installation series. Then, on production machines began to put advanced equipment, "Filin-N" under the PWG-28M missile production. The head of the PWG-28M had two different modifications subsequently added another, and was designed for four, and in view of the third modification of the GOS - six operating ranges that overlap virtually the entire frequency spectrum of radar use land and naval air defense system likely opponent. Furthermore, it is theoretically permitted to hit the communication station, although after a little experience in the use of this capacity gave negative results.
Kh-28 was very unpleasant to use. This was primarily due to the archaic power plant based on liquid rocket engine (by the way, it was done but the request of the customer, who wanted to unify the new product with the newly emerged far UR X-22 (D-2). Although the original X-28 projected solid fuel. In addition. Kh-28 was large and heavy, making se suspension is quite troublesome thing. But she had and strengths. In particular, it had a longer range - up to 45 km when starting with small and up to 75 km - from great heights. This made it possible to destroy the radar most of the most common while anti-aircraft missile complexes potential enemy without entering the zone of destruction.
Despite the variety of the arsenal, the presence of guided weapons and an unprecedentedly large mass of the load, the main armament of the aircraft, as well as many of his predecessors, remained a tactical nuclear bomb. According to the Ministry of Defense, at the time tactical nuclear potential of the USSR is several times higher than those of NATO supplies, and the emergence of such a perfect means of delivery as the Su-24, has further aggravated the imbalance in the European theater of operations.
All production aircraft received a special color with highly reflective white coating bow, the front edges of the wings and tail, and the bottom of the aircraft, and from serial aircraft -1415311, the Su-24 were completed with shutters that protect the crew from the light of a nuclear explosion. In addition to nuclear, it was envisaged and chemical weapons of mass destruction - in the post-war period in the Soviet Union was created a few dozen types of aviation chemical bombs and cassettes.
