According to defence sources, a major production contract with a Hyderabad-based firm—widely believed to be Astra Microwave Products Ltd, a key partner in the radar’s development—is expected to be finalised by mid-year. This contract will cover the manufacture of nearly 97 radar units plus additional reserves.
The finalisation of this deal is contingent upon the completion of final design validations and certifications, a timeline that synchronises perfectly with HAL’s manufacturing roadmap for the second Mk1A batch.
While the ELM-2052 is a formidable radar with a proven combat record, the indigenous Uttam is engineered to exceed these standards in specific domains.
Developed by the Defence Research and Development Organisation (DRDO), the Uttam radar is reported to incorporate approximately 912 Gallium Arsenide (GaAs) transmit-receive modules (TRMs).
This high density of modules significantly amplifies the radar's detection range, tracking accuracy, and ability to engage multiple targets simultaneously.
A higher volume of TRMs generally results in superior beam agility and robust performance in the face of enemy jamming.
