Harris will deliver Falcon III RF-7800 wideband tactical radios and accessories to an undisclosed Middle Eastern country.
Under the terms of the $88m contract, the company will provide the RF-7800H wideband high frequency (HF) tactical radio, RF-7850M radio and the RF-7800S lightweight soldier personal radio, as part of the next phase of the country's tactical radio modernisation programme.
The contract also includes the supply of vehicular and base station systems, accessories, spares and training services.
Harris RF Communications International business president Brendan O'Connell said: "Harris' strong presence in the region, combined with our continued investment in a leading-edge Falcon portfolio of tactical communications products and systems, enables us to transition our customers from legacy, voice-dominated communications to modern, networked wideband system solutions.
"These advanced communications systems will support the customer's current and future operational requirements for simultaneous secure voice and high-bandwidth data across a wide range of missions."
The RF-5800H is an advanced radio designed to provide troops with reliable and secure beyond-line-of-site terrestrial communications even in the harshest environmental conditions, such as mountains or urban terrain.
Weighing less than 600g, the Falcon III RF-7800S is a lightweight, secure soldier radio platform designed to provide full-duplex voice, multiple talk-group capabilities, as well as data and situational awareness communication to dismounted soldiers in frequency ranges from 350MHz to 450MHz.
Primarily used for wideband mobile ad-hoc networking, the RF-7800M helps commanders make more informed decisions and deploy forces quickly by enabling the transmission of secure voice and high-speed networked data services between squad-level forces and up-echelon command management platforms, from 30MHz to 2GHz.
Harris did not disclose the number of radios ordered and their delivery schedule.
