Deflector is done for the most part. Fitted the ship with more rugged, redundant, and damage-tolerant Bussard collector modules and twin phaser cannon turret modules in the barbettes for a total of eight barrels. This forms a highly effective 'Attack Cat' configuration. Turrets can lock directly forward or rearward for synchronized firing, or independently track any target in their fields of view including small highly-maneuverable fighters.
Nacelles [not visible] can be a Model 5-7 pair for an efficient 'Patrol Cat' configuration, or Model 7-11 nacelles fitted for a high-speed fast-reaction 'Cheetah' fit at the cost of some 40% of the original design range, but retaining substantially superior range to any pre-Kosinski ship. Both engine configurations would fit an offset field-control fin emphasizing maneuverability at warp.
