Thanks for the feedback. I can understand the Phalanx being taken off because it woul require funds to operate and mantain but I don't get the part about the classified FC technology. Other countries including Malaysia have in the past received ex-US ships with Phalanx.
When you decomm, you typically remove anything even remotely classified, and if you're handing a weapons system over, even to a friendly entity, certain aspects are removed or disabled. It may be functional, but will require replacement of the removed functions or components if they're critical to the system working at a certain baseline level. For example, radar systems will be reverted to a certain factory-default or have nation-specific capabilities like the selling country's IFF code interrogation logic board removed, or a less-precise terrain-mapping mode enabled. Just because they handed them over an R2-D2 on the stern doesn't mean it's the exact same CIWS on an Arleigh Burke Flight IIA. Nope, sometimes, the best weapons are the ones you built and tested yourself...
