Can somebody suggest to me as to how the figure for 11 or 22 or 33 was reached?
The AH-64E Longbow will preferably be used in pairs, largely to exploit the tightly networked capability but more importantly to use the hunter killer capability that the Longbow radar provides.
As such for the 14 Corps, the min number would come out to 28 Apaches 2 per Corps, which would really restrict them to only air battle management operations. In essence, the most powerful gunship would be transformed into a C2 asset, with its radars feeding data for the LCH.
At such low numbers, the corps can commit the Apaches only to one area, one division at a time, leaving several divisions without this newly aquired support. (The Longbow radar has a range of 8km, meaning it sweeps out an area of 200 km2. Thats just about a mid sized city). What does the corps do when more than one division is in desperate need for effective guidance? The LCH can perform strike missions, but without a mounted MMR radar, it will not be able to generate the situational awareness the commanders will want.
It would be better if every division were to have their own pair of gunships. That would mean a requirement of 34*2 Apaches. i.e. 68 Ah-64Es. Now, a certain number will have to be kept in reserve. That woyld be around 4-6.
Thus IMO, 72-76 would be an ideal number for the gunships. But of course the IA should have better understanding of the requirements.
Btw, the Saudi Arabian Armed forces have 94 Apaches
and your policies are hard to crack.
