Do you have any detailed information and background about the MiG 37 (English is also acceptable)

The MiG-370, nicknamed "FERRET", is a high-altitude, high-speed stealth interceptor aircraft designed by Russia in the late 1980s and early 1990s to counter the U.S. F-117 , project code 90. At that time, the project was assigned to Mikoyan and Sukhoi for design bidding. Sukhoi designed a twin-body layout aircraft, but ultimately failed to produce three prototypes of the MIG-37. The aircraft has high stealth performance and certain maneuverability. The main wings are arranged in a trapezoidal shape with a slight downward slope. The vertical tail is tilted 45 degrees. There are no canards. There are two speed brakes on the back. The nose is flat and has a prominent altitude. High-speed interception performance. Due to extremely expensive maintenance costs (one M-37 requires ground maintenance personnel equivalent to three SU-27s) and the emergence of fourth-generation fighters, the aircraft was ultimately not put into production and became a legend forever.
