The single AMM launcher realy is ineficient use of mass, because you need a missile fire control system (your Awl MCS) which takes mass. Add to this the mass of the launcher and you are at, what, 150 or 200t? for the ability to launch a single AMM each 10 seconds. If you put, say, 5 launchers on this ship, the mass only doubles (assuming the MCS masses 150t) from 200t to 400t, but you can launch 5 times as many AMMs.
I´d probably downgrade the passives, leaving the task of detecting the enemy to a dedicated fleetscout and use the saved mass for the additonal AMM launchers.
On second thought, I´d probably get rid of the AMMs alltogether and build a dedicated attack platform and another dedicated escort platform
I see you are using two CIWS. I´d probably switch those out for a single PD-turret. While this weakens the anti-missile defense, if the ship is on its own, I realy, realy don´t recomend sending single ships against an enemy. In a squadron, each turret will defend any ship in the squadron. If you have 4 of those cruiser in a squadron, this immediately doubles your last-ditch PD (4 turrets vs. 2 CIWS). If you can squeeze in a tripple turret (unlikely), it only gets better.
