Wouldn't be cheaper to just buy the ten aircraft covert them when they have the funds, otherwise it might be come very expensive. The price of the aircraft might go up!With the exception of the MAD and CMS, the the PN is already using the same inputs as the Swordfish on the Sea Eagle. I'd wager the PN will ask the UK or Canada for a MAD, and at the same time, work with the Turks on the AShM and LWT (i.e., get Atmaca and ORKA).
They'll buy in batches based on available cash. So, 1 now, 2 later, 2 after that, then 1 or 2, and so on until they get to 10.
