The US Air Force has awarded a delivery order to Raytheon to modify weapons data link equipment used in pilot training for F-15 fighter aircraft.

The $37.9m contract is part of the second delivery order awarded to Raytheon Technical Services Company LLC (RTSC) under a 2007 indefinite-delivery, indefinite-quantity (IDIQ) contract.

The contract order is for the air force training frequency relocation (TFR) programme.

An air force initiative, the TFR has been designed to modify GBU-15/AGM-130 weapons data link equipment.

The modification will be done to comply with federal reallocation of radio frequencies from governmental to commercial use.

Valued at $31.8m, the first delivery order, covering the non-recurring engineering work on the programme, was issued at the same time as the 2007 IDIQ contract award.
