LCA-Mk2

It is a 4.5 generation aircraft which will be used by the Indian Air Force.
It is a replacement for the Mirage 2000 class of aircraft.
It has got a bigger engine and can carry 6.5 tonnes of payload.
The technology is already developed in Light Combat Aircraft (LCA).
The LCA programme began in the 1980s to replace India's ageing MiG-21 fighters.
The LCA is being designed and developed with ADA as the nodal agency and State-owned Hindustan Aeronautics Limited (HAL) being the principal partner.
Its production is likely to start somewhere around 2025.

Advanced Medium Combat Aircraft (AMCA)

It is a fifth generation aircraft. And will be used by the Indian Air Force.
It is a stealth aircraft, i.e. designed for stealth and unlike the LCA, which is designed for maneuverability.
It has a unique shape to achieve low radar cross-section and has an internal carriage of weapons.
When the external weapons are removed, this aircraft has enough fuel and weapons inside to do a very capable operational role in stealth mode.
