Yep probably satin, definately not semi gloss.
I painted the hull of the Tamiya USS Missouri 1/350 in the meausre 22 color scheme. There are 4 colors to it, red anti foul, black anti foul, the navy blue in this thread and the top is haze grey. If the navy blue had too much gloss in it , it would look stupid so that's why in the end I decided on the AS-8 as it just looks correct. Although at $32 for the can.
I decided not to do the clear coat overlay as Cadet Chuck mentioned because it would have just been for that one color and I don't trust myself enough. If I screwed that up I could see myself remasking and painting another 4 times (one for each color).
