Stealth fighter jets will remain important, but stealth drones are likely to play an even greater role in the future of air combat. Manned-unmanned teaming (MUM-T) systems, in which a single manned fighter acts as a mothership controlling several stealth drones, are expected to become increasingly significant. India is already working on such concepts.
the engine for these drones is the dry-thrust version of the Kaveri engine. Kaveri was initially intended to power Tejas, but after removing the afterburner (wet-thrust) section, it was adapted into a dry-thrust variant that produces around 52 kN of thrust. This version is intended to power the GHATAK stealth unmanned combat aerial vehicle (UCAV).
India is also developing the CATS (Combat Air Teaming System), a family of unmanned systems designed to operate alongside the Tejas. Some of these drones feature low-observable designs and are intended to carry both air-to-air and air-to-ground weapons. They are powered by turbojet engines.

France is also developing the Neuron stealth UCAV, which is designed to demonstrate technologies for future combat drones capable of supporting manned aircraft such as Rafale.

These systems, together with continuing improvements in radar technology, interceptor missiles, satellites, and sensor networks, could provide the Indian Air Force with greater operational flexibility while waiting for the development and induction of the AMCA. stealth is no longer the same decisive advantage it appeared to be in the 1990s; it remains a significant advantage, but it is not a guarantee of survivability.
