According to below quotes, US C-130Js will participate in Ramstein Flag in Greece September 2024.
"The presentation of the carrier [C-130J, red] to the Greek staff is expected to take place by next September at the latest, when American C-130Js will be stationed in Greece for the Ramstein Flag 24 exercise."
Apparently a Lockheed Martin team has recently visited Greece to promote its C-130J as replacement for the current hard pressed C-130B/H fleet. But Greece feels no need to a hurry, as "... with the receipt of the "948" the 356th MTM now has three operational aircraft, with availability setting a record for years. Nikos Dendias has set a goal of 10 C-130s by 2025, a number that is achievable if you count the two supported in Portugal, the three that have joined the ODA and the two that will be acquired from the American stocks."
