Procurement cost comparisons in this space tend to conflate package values with airframe prices. Full programme figures routinely bundle simulators, initial spare parts pools, training pipelines and multi-year support contracts, making raw per-unit extrapolations misleading. The cleaner reference remains Austria's confirmed band of €130-150M per airframe, which places the C-390 and C-130J in a narrower acquisition band than is often assumed.
Where the C-390's structural case becomes genuinely compelling is not at the point of purchase but across the operating cost envelope. Cost per flight hour, CPFH, and lifecycle maintenance burden tell a different story: two V2500 turbofans drawing on a deep commercial MRO ecosystem versus four AE2100D turboprops on a purely military supply chain is a meaningful structural difference over a 30-year fleet life. The honest caveat is that independent, verified CPFH data for the C-390 doesn't yet exist at scale. Embraer's own case studies point in the right direction, but we're still in the early innings of building an operational evidence base.
(...)
Passing up the co-development offer from Brazil for the C-390 was such a idiotic decision.
Khagan1923 is right on the substance, even if the framing understates how consequential the decision actually was. The missed window wasn't just about getting a cheaper airframe. When Türkiye was at the table as a potential co-development partner, Embraer needed anchor customers and industrial credibility. That leverage doesn't exist anymore in the same form.
There is, however, one window that hasn't fully closed. The co-development opportunity is no longer what it was, Embraer now enters any partnership conversation from a position of genuine commercial strength, with a growing NATO customer base and an order book that has removed much of the early-programme risk it once carried. That changes the terms of engagement. But the doctrine-shaping customer role is still available, and it is a different kind of leverage.
Every C-390 operator so far, Portugal, the Netherlands, Hungary, Austria, South Korea, Sweden, has procured the platform for standard airlift requirements. Nobody has yet brought a serious SOF integration package, an electronic mission variant requirement, or a MALE support platform concept to Embraer with the fleet volume to back it up. That kind of customer generates a fundamentally different conversation with the manufacturer than a three-airframe order does.
Türkiye, when it eventually enters a C-390 procurement, will not be a single-digit buyer. A TurAF order at meaningful scale, paired with operationally specific requirements drawn from its actual doctrine, gives it something no current C-390 operator has offered: the combination of volume and mission depth that pushes a manufacturer toward variants it wouldn't otherwise prioritise.
That is where the broader strategic question connects. A large, doctrinally demanding customer doesn't just buy an aircraft, it shapes the platform's development trajectory. Push that logic far enough and you arrive at a different category of conversation entirely: not medium tactical airlift, but potentially even the heavy strategic transport gap that no Western programme is currently addressing. That is the thread worth pulling on, and it is one I outlined earlier in this discussion.
