I think that you can maybe learn how to make asset yourself for this game. It's not that I don't want to have those smaller ships and other type of aircraft you mentioned. There will never be short of list of things to create, it is just the community is short of creators to make those assets.

Oh and btw, for aerial type assets... Some smaller planes would be nice too like for example the Airbus A400M or CASA 295s... just an idea ;)

Wow man these are amazing, was waiting for exactly this (drones).

Since you're interested in naval assets... how about some smaller to midsize ships? These destroyers are pretty damn large so smaller navies, island nations and such would have smaller vessels. How about, for example the Fassmer MPV70 MKII (for Ecuador) or the US Navy Mark VI patrol boat? ;)
