I really doubt that would be the hull. IIRC, arsenal ships would be slow, large missile carriers, nothing more. because of that, they don't carry much sensors (which you have done correct) but because of that, I doubt they would have an sonar, especially that sonar!
the hull would most likely be one similar to (fast) container vessels, with an block coefficient of about 0.65.
the bilge keel on that position gives an huge drag penalty while not being of much use. also, pay attention to what parts are: the largest of the 'openings' in the hull is an diesel generator exhaust/coolwater spill from the perry class...... which is not only 20 years older then this ship (and by that should these days look at least slightly different) but you also have them on positions were those generators would most likely not be, such as next to the VLS.
note also that the propellers are high speed props..... not suitable at all for this ship. also, the engines are basically on top of the propellers here, so you are going to get problems there.
you will need cooling systems for the VLS as well
drawing wise, the bend-line in the hull should be grey IMO, as it is no 90 degree turn, and you have several 'beams' of the prearie masker system on wrong places and discontinioud below the waterline.
so, especially in the 'copying' work, there is a lot to do. yeah, that copying is not entirely your fault, as gunship made that mistake already on his burke, but this is exactly the reason why I tell people to use only the parts they know what they are.
