Hindustan Aeronautics Limited (HAL) has publicly revealed, for the first time, the front-end radar mounting structure developed for the Tejas Mk1A’s Israeli ELM-2052 Active Electronically Scanned Array (AESA) radar. Although no technical specifications were disclosed, the footage offers an unprecedented look at the radar integration process within the aircraft’s nose section and provides clues about the antenna’s likely dimensions.
With the radome removed, the video exposes the forward fuselage, including the radar mounting bracket, avionics bay, and structural support assembly. While the radar itself is absent, the mounting arrangement enables engineering estimates of the radar aperture. The circular mounting interface appears larger than previously seen, suggesting the Tejas Mk1A could accommodate an antenna measuring roughly 620–680 mm in diameter, placing it among the larger fighter-class AESA radars.
The installation is intended for the ELM-2052 radar family, whose octagonal antenna design maximizes radiating surface while fitting efficiently within the aircraft’s radome. The available internal space also appears sufficient to house transmit/receive modules, RF electronics, power systems, and liquid-cooling hardware required for AESA operation. Based on the visible dimensions, analysts estimate the radar could support approximately 1,100–1,300 radiating elements, though the exact number depends on the final antenna architecture.
The mounting structure is engineered to maintain precise antenna alignment under aerodynamic loads while supporting vibration resistance, cooling, and maintenance access. The disclosure comes as the Tejas Mk1A continues integrating major avionics upgrades, including the ELM-2052 AESA radar, digital electronic warfare suite, upgraded mission computers, and advanced cockpit displays. While HAL has yet to release official specifications, the footage indicates the aircraft is capable of housing a significantly larger AESA radar than previously believed, with current estimates remaining subject to confirmation.
