Zvezda Kh-31P (AS-17 “Krypton”) - A Radars’ Kryptonite
Hi and welcome to my 116th, which is about the Kh-31P anti radiation missile, hope you like it. 
First of all:
- Feel free to share more Information and / or correct me if something is wrong

Basic Background
Development of the Kh-31P anti-radar missile began in 1975 at the “Svesda” design bureau under the direction of G. I. Khokhlov. The impetus for this was the inadequate performance of its predecessor, the Kh-27PS, particularly in terms of range and speed. This forced carrier aircraft to enter the danger zone of modern air defense systems such as the Improved Hawk or Nike Hercules during missions, allowing the enemy to shut down their radar systems in time.
The goal of the new development was therefore a significantly greater range, higher speed, and the ability to engage enemy radar systems more quickly. Originally, a range of about 60 km and a weight under 400 kg were planned, but this proved technically unfeasible.
During development, it was also decided in 1978 to develop a naval target missile variant based on the Kh-31, which became known as the Kh-31A and can be used against surface ships with an active radar seeker and an armor-piercing warhead.
Flight testing of the Kh-31P began in 1982 on a MiG-27M. Various test versions were used to examine launch behavior, engine performance, stabilization, and aerodynamic and ballistic characteristics.
The Kh-31P Overall
The Kh-31P is an air-launched anti-radar missile designed to engage hostile radar systems. It employs a combination of mid-course guidance via radar and passive target acquisition during the terminal phase. The seeker covers a wide frequency spectrum and can operate in various modes, including an autonomous search mode and a mode with external target designation. If the missile is irradiated by enemy radar during the approach, it is capable of performing an evasive maneuver with up to 10 g.
Maximum range is approximately 110 km, while the minimum engagement range is about 15 km - with a maximum travel speed of approximately 1000 m/s.
The launch weight is approximately 600 kg, with the warhead weighing about 87 kg (allegedly SAP-HE). The Kh-31P can be deployed at carrier speeds of 600 to 1250 km/h and at altitudes ranging from 100 to 15,000 meters. Its dimensions are approximately 4.7 m in length, 0.36 m in diameter, and a wingspan of 0.91 m. The probability of hit is reported to be between 0.7 and 0.99, depending on operational conditions.
The Kh-31P In-Game
The implementation of the Kh-31P would be an interesting addition for air combat modes such as Realistic (RB) and Simulator (SB), as well as possible SEAD/EW / Strategic mode. The missile would work similarly to the ARMs we were already able to test: The player locks a radiating target, launches the missile, which flies autonomously to the target, while lofting quite high before impact, it may be difficult from some SAMs to intercept.
Aircraft in game that could use Kh-31PD (correct me with evidence in case I forgot some, except Chinese);
MiG-27M/K, Su-24M, Su-27SM, Su-30MK2 AMV, Su-30MKK, MiG-29M (9-15), Su-30SM, Su-30MKM, Su-30SM2, Su-34
