The Mikoyan-Gurevich MiG-21Bis (NATO reporting name FISHBED-L/N) is a single-engine, single-seat, supersonic fighter developed for the Soviet Air Force. The MiG-21Bis was first flown in 1972; it was the Soviet Union's ultimate development of the MiG-21, and included the Lazur Ground Controlled Intercept (GCI) system, a Tumanskiy R25 turbojet engine and another set of avionics updates. Variants of the bis were produced until 1985.
The North Korean MiG-21Bis is an inexpensive tank-hunter very similar to the MiG-21PFM. While it is billeted as a Ground Attack Aircraft, the Bis carries two short range PL-5 AAMs. The aircraft costs slightly more than the PFM: 85 points per aircraft to field, and has slightly improved ECM (20%). Its Kh-66 anti-tank missile is particularly deadly, with an AP value of 28. This missile can defeat any NATO tank's front armor, and with two aboard, the MiG-21Bis can be used to destroy top-end NATO armor for little cost. The Kh-66's major drawback is its poor accuracy. The MiG-21Bis' chief disadvantages are its relatively poor ECM and lack of long-range aerial missile compliment. Its PL-5 does add some flexibility, however, allowing the type to more effectively attack helicopters or defend itself against fighters. Its ECM will be somewhat adequate against older SAMs, but newer missiles will have little difficulty defeating the Bis' ECM.
