Actually, this tender suggested the PAA AH-1Z is indeed overseas, as I said before, the 3 AH-1Z is shipped off, and I believe it is somewhere inside Pakistan, and this tender actually supported my theory.
Why?
1.) This is a new preservation tender, which mean if the viper is made (which is a fact) and still have not been delivered or is in hold off since 2017, it should ALREADY be in preservation, they don't push a new tender out if the objective (preserve these viper) is ongoing. A new tender suggested these aircraft were in used before and now (as of June 28) is no longer in use, and is destined to be stored for 3 months.
2.) If the PAA Viper is still in US, DoD would not issue a tender for preservation because both Bell/Textron and USAF have their own preservation program, USAF boneyard in Davis-Monthan AFB and Bell/Textron have their own preservation warehouse in Texas, if the plane fall under either jurisdiction, they can preserve it themselves and not issuing a new tender for it, I mean why bother issuing a tender if you are going to put it in Arizona boneyard anyway, they will, however, send PAA the bill.
New tender contract means the aircraft is outside US service area, and most probably not under US jurisdiction, which mean they are either somewhere close to Pakistan and in Pakistan control, or they are in Pakistan and under Pakistan control.
Beside, the contract slated to end the preservation end in September/October, which is roughly my source said the remaining of Viper is due to deliver to Pakistan.
