Looking good at any angle, IAF Museum Palam's MiG-21bis now sports a shark's mouth and lightning flash after restoration. The Type 75 was designed for low-level, high-G manoeuvring dogfights with its uprated Tumansky R-25-300 engine, requiring a larger nose inlet diameter for increased airflow. It had the fastest rate of climb among the MiG-21 variants. Initially six aircraft built at GAZ-21 in Gorkii were delivered to India followed by CKD kits, and then manufactured under licence by HAL Nasik.

Framed in light at IAF Museum Palam, the Bis was the most numerous of the MiG-21 variants to serve the IAF, really a "People's Fighter". The Bis was remarkably agile in flight, as well as a good ground-attack platform. It used to be quite a sight coupled with the lovely double bangs of these fast movers as they went supersonic. For a long time the spear tip of IAF's fighter fleet, the MiG-21 has held the line through many conflicts.
