Ye-2 design modified for RD-11 turbojet. Six built. Identical to Ye-5 except for wings: Ye-2A had swept wings.

Why this record matters
“List of Mikoyan-Gurevich MiG-21 variants” is worth following because a concise public description often conceals a longer documentary argument. Here, List, Mikoyan-Gurevich and MiG-21 provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q11202580. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2008, 1954, 1956 and 1955.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
