From the article: "Since entering Portuguese service in 2023, the KC-390 has demonstrated outstanding mission reliability with a 99% success rate and low operational costs, reinforcing the country’s confidence in its capabilities."
I also keep reading that the number is 93% for the worldwide fleet and that operating costs are low. This seems to be a major selling point. But aren't these numbers a little overstated? All of the operational aircraft are just about brand new, not heavily used (at least not regularly for transcontinental travel, like the USAF), and the total aircraft numbers so far still only total about 13 (including prototypes). The Portuguese only have 2 new examples so far, so I would expect high success rates and low operating costs at this point in their careers.
I'm curious to see how they fare long term in Dutch service since out of all the committed buyers so far, the RNLAF has the most global/expeditionary commitments.
