Russia's new-generation PAK FA fighter — being developed by the Sukhoi Design Bureau — will have not only feature a new airframe, radar, avionics and engines. It also will be equipped with new-generation weapons that are being evolved in two parallel paths: the continued modernization of existing missiles with stepped improvement of their capabilities; and the design of next-generation weapons.
GosMKB Vympel, Russia's leading air-to-air missile design bureau, is busy evolving a full spectrum of missiles for the PAK FA, ranging from short-range weapons to long-range variants. In 2010, Vympel expects to complete its development of the short-range Izdeliye 760 missile — which is a significantly modernized version of the R-73 weapon, outfitted with an inertial flight control system and course correction receiver, improved rocket engine and with new multi-mode infrared seeker. The Izdeliye 760 is expected to be a close counterpart to the Western-built ASRAAM and Sidewinder AIM-9X missiles.
Three years later, the new-generation K-MD short range missile (also to be designated the Izdeliye 300) is to be operational. When compared to Izdeliye 760, the new missile will have longer range and will be capable of being launched from any direction; it will be also more resistant to jamming. The K-MD will be fitted with a new imaging infrared seeker enabling identification of target according to memorized images. The seeker's lock-on range will be two times greater than the seeker for the Izdeliye 760 missile. A new adaptive warhead will be introduced, and the missile's control will be performed with aerodynamic surfaces, as well as a thrust-vector engine nozzle.
Russia's most modern medium-range air-to-air missile is the R-77 (Izdeliye 170) and its export derivative RVV-AE (Izdeliye 190). A phased modernization of this weapon, designated the K-77-1 (Izdeliye 170-1), is now being tested. In addition, the K-77M (Izdeliye 180) missile is currently under development as a second step in the R-77's modernization. The most visible change in the Izdeliye 180's external appearance compared to the R-77/RVV-AE is replacement of its latticework fins by more common flat aerodynamic control planes. This reduces aerodynamic drag and cuts down on the radar cross-section. The missile will be fitted with a modernized active radar seeker and new double pulse solid-propellant engine. Its maximum range will be 2-3.5 times more than the Izdeliye 170 (R-77) missile, depending on the launch altitude. The Izdeliye 180 is expected to be better than the AMRAAM AIM-120C7 missile, and equal to its successor versions, with a service-ready date targeted for 2010.
A future medium-range air-to-air missile as a follow-on to the Izdeliye 180 also is in development, but no additional information has yet to be released about this weapon.
Russia is the only country developing ultra-long range air-to-air missiles able of reach targets at distances of up to 400 km. Two such missiles are competing to be a basic weapon on the PAK FA fighter: the Izdeliye 172 (K-100) from Novator, and the Izdeliye 810 from Vympel.
All air-to-air weapons on the PAK FA (including the largest Izdeliye 172 missile) are designed to be carried in the aircraft's internal weapons bay. To allow these weapons to be deployed from the internal bay, Vympel is designing two types of ejection release units capable of carrying 300 kg and 700 kg loads.
The PAK FA also is expected to carry its basic complement of air-to-ground weapons internally. These include the modernized Kh-58Ush long-range anti-radiation missile, the newly-developed Kh-36 short-range anti-radiation missile, the new short-range electro-optical Kh-38 missile, as well as the UAB-250 and KAB-500M guided bombs. Heavier weapon types will be carried on the aircraft's external pylons.

No cuesta nada un par de lineas en castellano para aclarar el tema. Que no todos dominan la la lengua pérfida.

¿Qué diferencia al IRIS-T del 9X o el ASRAAM?
Orel escribió:Cuanto más recorrido haga un misil (y 400 km es mucho), más probable es que lo engañen las ECM del objetivo (a él y al principio al radar que le esté pasando los datos via data-link), pues si logran irlo desviando un poquitín (haciéndole creer que el avión esta en otro sitio p.ej.), con 400 km de recorrido ese desvío será enorme, ¿no?.
Y las ECM de los AWACs suelen ser bastante buenas, precisamente porque serían objetivos prioritarios.
¿Y qué se sabe de su maniobrabilidad final?, algo clave, pues hasta un avión de transporte podría hacer maniobras evasivas tácticas y evitarlo si no es muy ágil. Y no olvidemos que cada vez más todos los aviones grandes militares llevan RWR y señuelos y ya hasta ECM (el A400M, por ejemplo, llevará incluso señuelo remolcado).

Creo que "Europa" (Europa occidental) nunca había ido por delante de Rusia en materia aeronáutica en campos tecnológicos punteros.
