First time posting on here, in watching and listening to Lockheed Martin's comments on the Canadian Surface Combatant I noted a few things. The radar that they are proposing is a scaled down version of their Long Range Discrimination Radar, it is built much the same way as the SPY-6 with scalability both up and downwards depending on the needs of the user, the gentleman from Lockheed in the video attached (14:25 Onwards) mentions this specifically as well as their Aegis ashore radar in Japan which would likely be closer in size to the version fitted to the CSC. In some other comments by Lockheed reps, there have been specific mentions of Aegis when mentioning the CSC so I would assume they are planning on the CMS 330 with some level of Aegis integration, or maybe a CMS 330 interface for the Aegis Platform much like the Hunter Class. Since we are still in the very early stages I wouldn't be placing bets on specific kit but there are some weapons systems that would be a lock in the timeframe that the first CSC's are delivered (Lockheed LRASM, BAE MK 45).
One thing I failed to mention is that if it is the same radar as fitted to the Aegis Ashore installations in Japan there will be some inherent BMD capability in the system should the RCN require or want the capability.
