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.
