M11

The M11 heavy cruiser is the largest Ashidi ship, and quite capable; it exceeds the capabilities of the stock Excelsior-class explorer on a hull that is .5mt lighter, using only about a hundred more crew and being overall significantly cheaper. They were likely developed to match the Cardassian Kaldar-class heavy cruisers, having superior science suites and endurance like the L7-class cruiser does over the Jaldun. Unlike that matchup, the M11 is indisputably tougher and better-armed than the Cardassian ship. It likely retains these advantages over the more modern Kaldar-bis, though they have been somewhat reduced and the Kaldar-bis would outgun it.
