AN AVIONICS upgrade is to be undertaken on the Pakistan Air Force (PAF) C-130 Hercules fleet following the award of a contract to Rockwell Collins for the work. Under the $30,727,886 Foreign Military Sales deal, awarded to the company on January 15 through the US Air Force Life Cycle Management Center at Robins AFB, Georgia, the contractor will be responsible for design, manufacture, integration, training and providing technical support during installation.
This will involve delivery of eleven C-130E model kits and five C-130B integrated avionics suites and kits. Additionally, Rockwell Collins will develop, validate and deliver consolidated C-130B/E flight manual and associated checklists, plus the maintenance supplements required to operate, maintain and sustain the PAF C-130 fleet.
Work will be performed at PAF Base Nur Khan, Islamabad, Pakistan, and is expected to be complete by December 31, 2020. Nur Khan, previously known as Chaklala, but renamed on October 10, 2012, is the main PAF C-130B/E base, housing the aircraft of 6 Squadron ‘Antelopes’ as part of 35 (Composite Air Transport) Wing.
The type is also flown by 21 Squadron ‘Pegasus’ at PAF Base Faisal, Karachi.
As previously reported on AFD, plans for the upgrade of the PAF C-130B/E fleet had initially been notified to US Congress by the US Defense Security Co-operation Agency (DSCA) on March 11, 2014. In addition to the avionics work, that notification also included plans for engine management and mechanical upgrades and cargo delivery system installation, together with outer wing replacement on six aircraft. This will be the subject of a separate contract. At the time, the DSCA gave an estimated total value for all of the avionics and other modernisation work as $100 million. AFD-Dave Allport
