Multi-purpose supersonic plane
In May 1965, IAP issued an order to create an experimental aircraft “158” with a variable sweep wing (VG) based on Е-155 (MiG-25). After 2 months this task was specified – to design “158” immediately as an attack bomber with the engine РД-19М.
Multi-purpose supersonic aircraft “158” with VG was created in variants of front rocket carrier, operational reconnaissance and fighter-interceptor.
The fighter-interceptor E-158P with variable sweep wing was calculated for two TRDF (turbojet) Р39-300 and radar sight “Smerch-100M”.
The E-158 attack vehicle was to be equipped with RD-19M engines and a Puma-A aiming and navigation system capable of flying up to 2000 km, with a terrain envelope at an altitude of 200 metres and a speed of 800-900 km/h. For the same range the aircraft could fly at a speed of 2500 km/h at an altitude of 20,000 meters.
From 1966, the aircraft “158” refocused on the use of a modified RD-36-41M engine.
This project has been further developed in the E-155MP and E-155MF projects.
