SharpEye™ radar for Pakistan Navy Submarine upgrade

Following the announcement in February 2017 that Kelvin Hughes will be supplying the SharpEye™ Doppler submarine radar system to the mid-life upgrade program for the Pakistan Navy’s Agosta 90B-class (also known as the Khalid class diesel electric attack submarine), the order for the next submarine in this program has been placed.

Working with Turkish defence contractor STM, the main contractor for the refurbishment programme, Kelvin Hughes will supply the SharpEye™ system to the first submarine in 2018 and the second in 2019.

The upgrades are being performed at the Karachi Pakistan Naval Shipyard however specific details concerning each submarine in the program have not been disclosed.

The SharpEye™ I-Band (X-Band) radar transceiver for submarines is based on a downmast transceiver housed in an enclosure located within the pressure hull and provides submarines both in-service as a retrofit and new classes a high performance solid state radar with similar capabilities to SharpEye™ radars installed on naval surface ships.

This downmast submarine radar solution makes use of the existing bulkhead infrastructure in the pressure hull, removing the need to replace the antenna mast system by utilising the existing external antenna, rotational drive and waveguide connections. Kelvin Hughes also manufactures and supplies a pressure resistant 'AZL' submarine antenna.
