Unlike shipbuilding which Canada has shown itself to be moderately successful in as of late, setting ourselves up for the Saab fighter "production" proposal domestically is a laughable waste of time. More relevant to the discussion here however, the adoption of a two tiered fleet has some potentially disastrous consequences for cross service interoperability between the RCAF and RCN. The AEGIS equipped River class destroyers are out of the box able to integrate themselves seamlessly with the MADL datalinks of the F-35A, permitting them to discretely share substantial amounts of data quickly to the point that you can create high quality targeting tracks able to gain weapons locks on targets. Gripen E/F only has NATO standard LINK datalinks which while adequate, offer nowhere near the fidelity, bandwidth, stealth and interoperability that the MADL offers from the F-35.
Yet another example of poor procurement decisions being weighed due to emotional, politically charged situations.
