India’s indigenous light combat aircraft, the Tejas MkII, is set to make history as the first Indian fighter jet to feature a Gallium Nitride (GaN)-based fire control radar, known as the Uttam Aesa. This groundbreaking development marks a significant leap forward for India’s aerospace industry, showcasing the nation’s technological prowess and commitment to self-reliance in defense manufacturing.
GaN, a newer semiconductor material compared to Gallium Arsenide (GaAs), offers several advantages that make it ideal for advanced radar systems. Its superior properties enable the development of smaller, lighter, and more efficient radar components. GaN-based devices can handle higher power levels and operate at higher frequencies, leading to improved detection range, accuracy, and tracking capabilities.
The Uttam Aesa FCR, equipped with GaN-based technology, will provide the Tejas MkII with a significant edge in aerial combat. The radar’s enhanced performance will enable the aircraft to detect and track multiple targets simultaneously, even in challenging environments such as clutter and electronic countermeasures. This capability will enhance the Tejas MkII’s situational awareness and survivability.
Furthermore, GaN-based radars are known for their lower power consumption, which translates to increased flight endurance for the Tejas MkII. This is particularly important for long-range missions and operations in austere environments.
The development and integration of the Uttam Aesa FCR into the Tejas MkII is a testament to the expertise and innovation of India’s aerospace research and development community. It showcases the country’s ability to compete at the forefront of global military technology.
