On my regular journeys through the strange world of EU Council documents, I found an agenda of a so-called "Special Committee ATHENA".
According to the former Czech Council Presidency (here), "[t]he Special Committee ATHENA deals with funding of ESDP military operations". And the Swedish Presidency tells that ATHENA meets 12 times a year.
And when you you google the term, you find lots of interesting information on EU military missions, including more detailed explanations of ATHENA on the Commission website and on the website of the Council.
One more detail on how the EU is working behind the scenes.
