The R-77 missile is superior to Amaraam missile in all aspects&more maneuverable than it.Work on the R-77 began in 1982. It represented Russia's first multi-purpose missile for both tactical and strategic aircraft for fire-and-forget use against a range of aircraft from hovering helicopters to high speed, low altitude aircraft. Gennadiy Sokolovski, general designer of the Vympel Design Bureau, said that the R-77 missile can be used against medium and long range air-to-air missiles such as the AIM-120 AMRAAM and AIM-54 Phoenix, as well as SAMs such as the Patriot. It can be used against cruise missiles and precision-guided munitions (PGMs). First seen in 1992 at the MosAeroshow '92, the R-77RVV-AE was immediately nicknamed Amraamski by Western journalists. The Russian-language version of the acronym for the weapon is RVV-AE and it is also known as the Izdieliye-170.
The R-77 can be used by most of the Russian Air force fighter aircraft. Since many of their aircraft, primarily MiG-29, Su-27 and MiG-31, were upgraded recently. The same is true for the PLAAF of China, who use the Su-27 as well as a copy, the J-11. The newer Su-30MKK has a N001 (Su-27 radar) with a digital bypass channel incorporating a mode allowing it to use R-77s. Newer Russian aircraft from the MiG-29S (N019M radar) onward are not restricted in this regard.
There are other variants under development. One has an uprated motor to boost range at high altitudes to as much as 120–160 km; it is known as the R-77RVV-AE-PD. The 'PD' stands for Povyshenoy Dalnosti, which in Russian means Improved Range. This variant has been test-fired and uses a solid-fuel ramjet engine. Its range puts it in the long-range class and is equivalent in range to the AIM-54 Phoenix. In another version of the R-77, a terminal infra-red homing seeker is offered. This is in line with the Russian practice of attacking targets by firing pairs of missiles with different homing systems. This complicates end-game defensive actions for the target aircraft, as it needs to successfully defeat two homing systems. This method of attack may not always be available as IR seekers typically have less range and less resistance to poor weather than radar seekers, which may limit the successful use of mixed seeker attacks unless the IR missile is initially directed by radar or some other means.The weapon has a laser fuze and an exploding rod warhead that can destroy the variable sized targets. A product-improvement of the R-77 Adder is in the works, codenamed the R-77M1, and will feature a ramjet propulsion device. This heavier missile system will have a much greater range, and will surely be the primary beyond visual range (BVR) air-to-air weapon in upcoming fifth generation Russian frontline fighters.
The radar-guided R-77 has been sold widely, with China and India placing significant orders for the weapon, as was the case for the R-73. The baseline R-77 was designed in the 1980s, with development complete by around 1994. India was the first export customer for the export variant, known as the RVV-AE, with the final batch delivered in 2002.Vympel was the victim of a lack of adequate funding during the 1990s and the first part of this decade to support further evolution of the R-77, either for the Russian air force or the export market. The basic version of the R-77 is not thought to have entered the Russian air force inventory in significant numbers.
Additionally, Western suppliers have been pushing into some traditionally Russian markets and some major customers of the R-77 such as India and China have been pursuing their own missile programs ,with similar goals, such as the Astra and the PL-12, respectively.There is variants of the missile with range up to 160kms.
