1. Rafael (Rafale): This is a 4.5 generation multirole fighter aircraft developed by Dassault Aviation.

2. MiG-29: This is a fourth-generation multirole fighter aircraft developed by Mikoyan in the Soviet Union.

3. Tejas MK-1: This is a fourth-generation light multirole fighter aircraft developed by Hindustan Aeronautics Limited (HAL) in India.
