Its wing and tailplane had 57° sweep, S-12 4.2% thickness airfoil was utilized to obtain stable but versatile platform for flight test in uncharted envelope of speeds. Conservative layout of the E-2 resembled earlier SM-12 prototypes. Aircraft was assembled at GAZ-155 by late 1954, and earl next year pre-flight trials started.
First flight took place on February 14, 1955 (bureau test-pilot Georgiy Mossolov). First trials revealed no advantages of ether delta or swept wing (E-4) prototype, and one more prototype of each layout was ordered. E-2A and E-5 (swept wing and delta, accordingly) had even more powerful AM-11 (RD-11).
E-2A took off on March 22, 1956, piloted by test-pilot G.A.Sedov. In addition to the new engine, it received a single fence on each wing upper surface. Performance improved substantially compared to E-2, and pre-production series of five planes was built. Those five appeared for the short time (on the experimental stage) under the designations MiG-23 and "product 63".
The fuselage of the E-2/E-2A was very similar to that of the early MiG-21. On June 24 1956 new jet made first public appearance at Tushino airshow - much to the surprise of Western observers. NATO thought that this aircraft was in service as the MiG-21 and assigned the name 'Faceplate'.
Trials of E-2/2A and their delta-winged siblings generated considerable data. Finally, the E-5 showed better qualities and was therefore selected for mass production.
On-board equipment included ASP-5N; SRD-1; RSIU-4; answerer BARIY-M; ARK-5; MRP-48P; SIRENA-2.
