So thats the question right? How many does Pakistan actually possess?
UCAV: being very generous, no more than 180
Akinci: as of 2023, it had 6-7. Even if we generously say it got another batch, maximum 12-14 total, but more likely still 6-7.
TB-2: last stated number was 20. If we again give benefit of possible additional unreported deliveries at most 30-35
WL2: ~50
CH-4: 24
Shahpar II: 12-30
Anka?: 24
Buraq: unclear but from various sources i could find between 20-30 if it is in service at all anymore
Recon: again generously 150-155
Jasoos 2: 45-50
Falco: 24
Uqab: 50
Salaar 30
So maybe in the 300s for major UAVs/UCAVS.
Unknown number of kamikaze dribe or smaller units not listed above, but it is unlikely to be anything on the level of what Iran possesses.
