Boeing has received a contract from the US Air Force (USAF) to manufacture and deliver an additional 2,424 combat survivor evader locator (CSEL) combat search and rescue radios.

Under the $21.4m contract, the company will provide a complete package of CSEL that includes radio sets and adapter spares, rechargeable batteries and battery adapters.

Boeing CSEL programme manager Steve Capps said the locator allows rescue teams to save lives using multisatellite, real-time communications and GPS.

Delivery of all components will be completed by April 2012.

Boeing has delivered more than 43,900 CSEL radios to the US Air Force, Army, Navy and Marine Corps, and the current agreement is the fifth CSEL contract for the USAF.
