The Saudi Arabian Army has awarded a contract to Sikorsky Aerospace to upgrade its fleet of Black Hawk helicopters.

Under the contract, Sikorsky will upgrade the Black Hawk fleet from the UH-60 A model configuration to the latest UH-60L aircraft configuration.

The upgrades to the helicopters will be carried out under the Royal Saudi Land Forces Aviation Command (RSLFAC) A-to-L modernisation programme.

Key improvements in the A-to-L modernisation programme include T700 to T701D engine upgrade for increased power and reliability, and flight control, avionics and instrument panel modifications.

In addition, the upgraded H-60 helicopters will be equipped with a new aircraft flight control computer, wiring harness, high-speed shaft and seal lead acid battery.
