In accordance with the Council of Ministers resolution dated February 5 1962 and
the Ministry of Aviation Industry order dated February 17, 1962, two E-152
aircraft had to be re-equipped for tests and final development of S-155
intercept complex. New R-15B-300 engine had to be installed on the E-152/1
aircraft, and flight tests of this new engine should be carried out. E-152/1
aircraft had to be equipped with «Smerch-A» system and K-80 rockets
for system tests and development in the interests of 155 aircraft.
E-152M aircraft was armed with two K-80 rockets providing target seeking from any aspect angle, which were slung under wingtips. Aircraft was equipped with «Smerch-A» radar, SAU-1I «Polet» automatic flight control system, «Lazur-M» airborne equipment for command data link, RSBN-2 «Iskra» short range navigation and landing system and KSI compass system. Aircraft was powered by R-15B-300 engine that had increased thrust and fully variable nozzle. Additional fuel was loaded into three fuselage-fairing tanks and in the first fuselage tank.
It was intended to mount destabiliser on the fuselage nose. Therefore nose and tail parts of E-152 fuselage, as well as underwing rocket stores, had to be modified.
Re-equipment of E-152/1 aircraft began after its world record flights and was finished by the late 1962 when the aircraft was equipped with a non-standard engine. E-152M/2 manufacturing was delayed due to absence of standard engine. The aircraft fitted out also with non-standard engine was assembled only by June 1963 and was transferred to the flight test station of the plant on June 14 1963. R-15B-300 No 8 engine delivered in November 1963 and installed on E-152/1 aircraft could be used only for ground tests of aircraft with engine running. Flights were not made since a permit to operate engine in-flight was not available. Flight tests of these aircraft were not started in 1963-1964 because the R-15B-300 engines suitable for flight operation were not delivered. Therefore, the program was cancelled, and E-152A aircraft was used for experimental work.
After completion of tests E-152M, in July 1967 the machine have shown on the exhibition at the airport Domodedovo. Its fuselage decorated an inscription «E-166» and three small asterisks, indicated about an establishment of world records. However all this did not correspond to the validity - records were set on the first prototype airplane E-152-1, and the name «E-166» was thought up for FAI with the purpose of observance conventional Soviet conspiracy. After the exhibition E-152M aircraft was transferred to Monino Air Force Museum.
