Its real and its Rawalpindi
Upgrading 48 x AH-1F would have added a better punch since the upgrade brings the capabilities of -1F closer to -1Z, even the ability of firing AGM-114R, which combines an anti-tank warhead with a fragmentation sleeve for use against both armored vehicles and soft targets. The main object of interest, LongBow Radar, is already not coming with -1Z while it has been provided across the border to IAF AH-64E.
Even then, if Pakistan gets the following from original deal, minus the -1Zs and the Engines, the upgrades of older -1F would have been worth it.
1000 x AGM-114 R Hellfire II Missiles
36 x H-1 Technical Refresh Mission computers
17 x AN/AAQ-30 Target Sight Systems
30 x 629F-23 Ultra High Frequency/Very High Frequency Communication Systems
19 x H-764 Embedded Global Positioning System/Inertial Navigation Systems
32 x Helmet Mounted Display/Optimized Top Owl
17 x APX-117A Identification Friend or Foe
17 x AN/AAR-47 Missile Warning Systems
17 x AN/ALE-47 Countermeasure Dispenser Sets
18 x AN/APR-39C(V)2 Radar Warning Receivers
15 x Joint Mission Planning Systems
17 x M197 20mm Gun Systems.
The -1Fs could have been upgraded with the following:
L3 Wescam MX-15D sensor turret which is similar to -1Z's AAQ-30A thus allowing the -1Fs to use the new sensor system with Hellfire missiles and Advanced Precision Kill Weapon System II laser-guided rockets, or APKWS II.
OrbitalATK AN/AAR-47 missile approach warning system coupled with an Extant Aerospace AN/ALE-47 dispenser able to fire decoy flares and chaff. Replacing all analog systems with LN-251 inertial navigation system.
The -1Zs provide advantages like precision strike, enhanced survivability and can operate at high-altitudes. It would have been more sensible to help the Turkish with their engine issues for the option of T-129, which provides similar advantages over older -1Fs, probably by letting go of -1Zs along with spare engines altogether. T-129 would have had a major advantage of Mmw Radar which -1Zs don't bring with them. WZ-10 would have bolstered older but upgraded -1F Cobras and it would also have its own MmW radar,but then again 20mm gun vs 23mm gun as logistics burden. Lastly, Mi-35 are already in service with their 23mm guns where as T-129 employs 20mm guns. This covers all the terrain from east and west, from north to south for PAA in case of gunships, but that is a sordid mixture of American, Turkish, Chinese and Russian ATGMs. Then the spares, upgrades and technician/pilot training on 4 different machines, if -1F retire; another ball game.
