I actually see a different possibility. That a critical piece equipment needed for the LPD has arrived for the UAE's LPD but not for the Philippine LPD. I don't believe it's a payment issue from the Philippines. The way Philippine defense procurement works, it's really difficult to get something funded, but once something is funded, the money is earmarked and can't really be used for something else. Of course the way it works isn't with physical money, but basically the authorization to transfer the money would have been approved beforehand and can't really be canceled without someone really high up overriding the authorization.Max Defense and Philippines forums gone livid when they see the UAE LPD being assemble before theirs. Seems even the official PAL has not said anything yet, but enough noises already shown this is UAE's LPD.
Well when one customer being move ahead of schedule from other ones, I only see one possibilities. UAE already ahead on payment schedule then Philippine. Still this is why PAL rushing to prepare FMP for late this month launch. They need the space for other ship, and most likely Philippine LPD#1.
As for which equipment, not sure. But I notice that with the Guarani APC, Germany withheld authorization for use of their diesel engines for three years. No idea why, but that's why it took so long to deliver the APC. It's not impossible something similar happened with the MTU marine diesels powering the Philippine LPD. We'll find out what's really going on later, I guess.
