the launchers you have used are Mk 143 ABL launchers. look them up and you see why my concerns

the SMART-L is bloody powerfull. the TRS-3D/32 is good, but not as powerful as the SMART-L. it is just a generation before, and not build to work with the APAR........ as far as I can see, in all but cost the SMART-L would be superior.
sonar dome should be as forward as possible. you want it to have as less interference from the ship pushing itself trough the waters as possible. the auxilary thruster.... when serving as a bow thruster, you want it as much forward as possible, but when as auxilary it can be wherever you want it. if it is sized for being an propulsion power, it is bigger then required as bow thruster and thus it is less of an requirement for it to be placed fully forward.
mine sensors are most of the time integrated in the sonar dome, IIRC.
