Indian firm Data Patterns has unveiled its HAWK I 2700 multifunction fire control and tracking radar at the Aero India 2025 show in Bangalore.

A Data Patterns spokesperson told Janes on 11 February that the radar is being developed as part of a project to replace the ageing Russian N011 Bars radar system fitted onto the Indian Air Force's (IAF's) Sukhoi Su-30MKI fighter aircraft.

The spokesperson added that the HAWK I 2700 is being developed indigenously in line with New Delhi's ‘Make in India' policy.

The HAWK I 2700 radar operates in X-band frequency, between 8 GHz and 12 GHz. According to Data Patterns, the radar has search and tracking modes of operation. In search mode it can achieve a range of 250 km, and in tracking mode its range is 200 km, the company said.

The radar's wide field-of-view of up to 100° enables the HAWK I 2700 to detect and track multiple targets simultaneously, the company said. It added that its solid-state active phased-array architecture provides high-precision accuracy in both azimuth and elevation data of the targets.

Maximum throughput of the fire-control radar (FCR) is up to 9 kW and it can provide maximum surveillance across a range of 350 km. Gallium nitride (GaN)-based transmit/receive (T/R) modules used in the radar feature high-output power and enhanced range-detection capability. The radar's sidelobe suppression and frequency hopping methods are intended to enable the radar to operate in dense radio frequency environments.

The HAWK I 2700 radar also features electronic attack modules that can jam enemy radar emissions while operating in an electromagnetic-contested environment.
