The third LOA provides for the Mid-Life Update (MLU) of their current fleet of forty-six aircraft: four of these aircraft are in Fort Worth undergoing Trial Verification Installation, which is part of the MLU program. Under the MLU LOA, Pakistan is procuring Falcon STAR structural upgrade kits for the thirty-two original F-16A/B aircraft and thirty-five MLU avionics upgrade kits for the current fleet (including three of the recently transferred EDA aircraft).
There is an option on the contract to procure eleven additional MLU avionics upgrade kits for the remaining eleven aircraft. Pakistan has not yet exercised this option, but plans to do so at a future date. The Falcon STAR structural upgrade is very similar to that provided to other F-16A/B customers. Falcon STAR replaces critical structural components in the F-16 required to return the A/B airframe to a structural life of 8,000 spectrum hours. Falcon STAR is required to keep the original thirty two PAF F-16A/Bs air worthy.
The Pakistan MLU avionics upgrade kits are being designed to provide the Pakistan Block 15A/B aircraft with many of the same capabilities as the new Block 52 F-16s that the PAF is procuring.
The MLU kit replaces most of the 1980s avionics in the Block 15s with newer, advanced avionics systems from the Block 52 F-16s. The MLU upgrade kits will include:
- APG-68(V)9 radar;
- Embedded GPS/INS (EGI);
- Link-16 data link;
- APX-113 Advanced Identify Friend or Foe (AIFF);
- Color Cockpit with Color Moving Map;
- ALQ- 211(V)9 Advanced Integrated Defensive Electronic Warfare Suite (AIDEWS) Pod;
- Night Vision Imaging System (NVIS) Cockpit and External Lighting;
- Sniper Advanced Targeting Pod;
- Joint Helmet Mounted Cueing System (JHMCS);
- Reconnaissance Pod capability;
- improved avionics systems;
- JDAM capability;
- EGBU capability;
- AIM-120 AMRAAM capability;
-and AGM-84 Harpoon capability.
While many of the avionics systems and capabilities are common with the new Block 52s and the MLU, some significant differences remain between the MLU F-16 Block 15s and the new PAF Block 52: there are no improvements to the Block 15s mission range and loiter time; there are no engine improvements; and, there are no improvements to payload capacity. Overall, the MLU program will extend the service life of Pakistans original F- 16 aircraft and very significantly increase the capability of the Pakistan Air Force to conduct Close Air Support and night precision attack missions. I would like to highlight that in parallel with the significant improvement in weapon accuracy gained by precision guided munitions like JDAM, there is the potential to dramatically reduce collateral damage and civilian casualties.
Regarding program status, the first four MLU aircraft are undergoing work in Fort Worth, Texas now. The USAF schedule for delivery of these aircraft is December 2011. The delivery dates for the remaining aircraft are being refined due to the recent stop work.
