The design bureau studied several possible layouts for the new aircraft. One had the engines located side by side, as on the MiG-19. The second had a stepped arrangement with one engine amidships, with exhaust under the fuselage, and another in the aft fuselage. The third project had an engine arrangement similar to that of the English Electric Lightning, with two engines stacked vertically. Options two and three were both rejected because the size of the engines meant that either of them would result in a very tall aircraft, which would complicate maintenance.
The idea of placing the engines in underwing nacelles was also rejected because of the dangers of any thrust asymmetry during flight. Having decided on engine configuration, there was thought of giving the machine variable-sweep wings and a second crew member, a navigator. Variable geometry would improve manoeuvrability at subsonic speed, but at the cost of decreased fuel tank capacity. Because the reconnaissance aircraft would operate at high speed and high altitude, the idea was soon dropped. Another interesting but impractical idea was to improve the field performance using two RD36-35 lift-jets. Vertical takeoff and landing would allow for use of damaged runways during wartime and was studied on both sides of the Iron Curtain. The perennial problem with engines dedicated to vertical lift is they become mere dead weight in horizontal flight and also occupy space in the airframe needed for fuel. The MiG interceptor would need all the fuel it could get, so the idea was abandoned.

Missiles:
During the Persian Gulf War, a U.S. Navy F/A-18, piloted by Lieutenant Commander Scott Speicher, was shot down on the first night of the war in the early hours of 17 January 1991 by a missile fired by a MiG-25.[65][66][67] The kill was reportedly made with a Bisnovat R-40TD missile fired from a MiG-25PDS flown by Lt. Zuhair Dawood of the 84th squadron of the IQAF
On 13 February 1981, the Israeli Air Force sent two RF-4Es over Lebanon as decoys for Syrian MiG-25 interceptors.
Two IQAF MiG-25s were shot down by U.S. Air Force F-15s on 19 January. The MiGs attempted to hide from the F-15s by using chaff and electronic jammers in order to engage the F-15s.
