Worth highlighting that the PAF currently operates 12 Erieyes, including 05 later-inducted “ER” variants. While exact figures are not public, the general consensus places the Erieye ER’s detection range at around ~600–650 km Vs ~500 km for the earlier version.
There have also been unconfirmed reports suggesting that the older Erieyes may be undergoing MLU to ER standard at PAC Kamra. Notably, in the post-clash briefing the following day, the PAF spokesperson confirmed that the Erieye ER was part of the 7th May night package.
As always, the PAF has kept details regarding the Erieye fleet and Blinders Squadron fairly limited — and at times somewhat confusing — in the public domain.
