...Jos puikko ei ylläkään sille korkeudelle, josta MATKUSTAJAKONEITA
pudotetaan, niin SU-sarja ja muutkin ihmepommittajat joutuvat kyllä kyntämään niillä korkeuksilla, joihin NASAMS kyllä yltää.
Kun aasinsiltaa suorastaan tyrkytetään, niin laitetaan tänne.
Su-25:lle ilmoitettu vaatimaton lakikorkeus ei johtune koneen aerodynamiikasta, vaan niinkin yllättävästä ja yksinkertaisesta seikasta, että ohjaamo on paineistamaton: "The pilot sits in an unpressurized cockpit surrounded by a titanium "bathtub," and is protected by heavy armor from all sides."

Su-39:ssä ohjaamo on paineistettu (mainittu mm. airwar.ru:ssa) ja lakikorkeus lähteestä riippuen 10-12 km.
Su-25 voitti helmikuussa 2013 Venäjän tarjouskilpailussa Yak-130 pohjaisen Yak-131:n (yksipaikkainen). Uutukainen on Su-39:n näköinen, rakennettu siis kaksipaikkaisen Su-25UB:n runkoon, jossa takaohjaamoon on sijoitettu polttoainesäiliö yms. Koneeseen suunnitellaan mm. aesa-tutkaa, koska yhden aesa-elementin hajottua koko tutka ei ole rikki. Nykyinen tutka on Kopyo-25 asennettuna tuohon ylläolevassa kuvassakin näkyvään valkokärkiseen keskilinjan podiin.
"MoD preferred modernized Su-25 Russian-Italian Yak-131
Russian Air Force will receive the latest attack
In the Russian Air Force will attack the new generation. Such planes are needed for aerial bombardment of ground vehicles, infantry and other objects of the enemy. Take as a basis the Soviet Su-25, he liked the military more than the latest Russian-Italian Yak-130, which was too small.
As told "Izvestia" in Command of the Air Force, the final results of the competition to design and build a new ground-attack aircraft Defense Ministry will announce on February 17.
- Main Command of the Air Force chose between him and the Yak-131, upgrading the training of the Yak-130, eventually won a modern version of the old Soviet design - told "Izvestia".
The contest was announced in 2011. Air Force formed a tactical and technical requirements (TTP) to the aircraft in early 2012, and in May the "Dry" and "Yakovlev" provided documentation for participation in the competition. According to the requirements, attack should act around the clock in any weather, equipped with radar and precision weapons, and finally be heavily armored and Single. According to these parameters lightweight double Yak-131 military has not approached.
Another requirement BBC - readiness for flight tests in mid-2014, as the plan to run new car in the series no later than 2020. On assurances representative military-industrial complex, a deep modernization of the Su-25 actually makes it a new plane.
As a basis, he said, taken combat training version of the Su-25UB. Co-pilot take the fuel tank so that the combat radius will increase from 300 to 1 thousand km. Completely change the nose and the cabin, which will be sealed. Su-25UB 5 thousand meters above does not fly, and a promising attack could rise by 10-11 thousand. Gross take-off weight - 14.5 t, load capacity - up to 6 tons
Instead of the old sighting system "Maple" is new under the symbol SALT 25 (optical system, laser, thermal). As is clear from abbreviations complex combines a laser range finder and a television camera high-resolution, combined with the thermal imager.
- Initially aviators prescribed in TTZ equipment night vision goggles and helmet-mounted pointer. You know, American pilots such optical devices on the eye, so that he could fix a glance target location. But in the course of their work rejected as SALT-25 allows the pilot to do without special tools on the eye - said a source in the defense industry.
Developers plan to equip the aircraft with radar-active phased array, although the specification is no such item. Sighting system combined with radar will give the opportunity to attack aircraft in one approach guaranteed to destroy at least four goals, hopes in the CMO. Main fire it will be a complex supersonic anti-tank guided missiles "Whirlwind".
Aircraft promised high maneuverability with full ammo (can withstand overload 5G, ie close to the critical human), survivability, simplicity and reliability of the equipment.
- Why do we want it active-phased array radar? Because it is more reliable antenna operates at failure of individual modules. And try to knock out all the modules! Another promising attack is easy to use and manage. For example, modern fighter-bomber is prepared for five hours on a single sortie. Where it suits? Our much easier - said the representative of the defense.
His colleague from the military aviation industry says that designers have already reached the limit of options in terms of materials, aerodynamics, strength.
- Doing something completely new for very long. And if you change only the equipment immediately gain in quality and time. What difference will fly the plane to 1 thousand km or 1.05 thousand km? But acquire new qualities, aircraft will be able to work on multiple targets in one go using one volley of missiles 4-6, - "he told Izvestia."
Independent expert on military aviation Anton Lavrov believes that the Ministry of Defense continues to pay special attention to the planes of the battlefield.
- High-precision armament significantly increases the survival gunship in modern conflicts. Provided by the project scope changes Su-25UB makes it impractical to modernize the current combat aircraft, of which the youngest of more than 25 years - said the expert "Izvestia".
Lavrov expressed doubts soon serial production of the new gunship and suggested that he would be "protracted"."

Ukrainan SU-25:t on modernisoitu SU-25M1 -tasolle, josta kehaistaan koneen pystyvän pommittamaan gps-pommeilla pilviverhon läpi. "Secondly, through the installation of a satellite navigation system capable aircraft hit targets even when the pilot can not see them visually, but he knew their coordinates. The aircraft can now use standard weapons against ground targets day and night, in poor visibility conditions and without leaving behind the clouds. Significantly, nearly 3 times the altitude increased use of weapons."
