Here you can find a selection of maps for the game Star Trek: Armada.
If you are interested in getting all of them at once but still as 7zip archives, use the files in folder packages_all_maps. The files in there contain all maps packaged for easier bulk download.
If you are more interested in the single archive files, open folder packages_single_maps. Each 7zip contains one map including its mds, bzn and bmp file.
