Problem may be more widespread than officials acknowledge.
Having effective sensors, fire control, ordnance and control systems is only part of the picture for building a capable shipboard combat system. The task that makes all of these play together is called combat system integration, or CSI.
Many foreign navies rely on CSI to pull together shipboard combat systems that have components originating from different suppliers. If integration is not done well, it can be very costly and take years to do what should take months. Valuable warships needed for naval missions can be unavailable for years. The result is best described as combat system dis-integration.
