Hi Rangitoto. You may be right, however, I'm sure over the past 20 years Thales would have up-graded and improved this APAR Block 1 to the point of a modern 4-sided Phased Array SSR (APAR Block 2)? I don't think the RCN would want 20 year old (25 years before we see it) technology and try to integrate it with the S Band SPY 7 (V) 1. Just wouldn't work. It would be great if LM were to invest in say, an X Band (SPY 7 (V) 4 ?), to compliment the SPY 7 (V) 1 S Band LRDR. If so, why would LM not just create a Dual Band (S+X) SPY 7 (V) 1. If that were the case, why do I still see some sort of X Band radar on every image of the CSC Frigate (either on the top or bottom of the SPY 7(V) 1). I am still leaning towards APAR Block 2 X Band radar. The more I think of it, the more confusing this mystery becomes. One thing is for sure. The CSC Frigate needs some sort of modern X Band SSR to compliment the SPY 7 (V) 1 and integrate seamlessly with the CMS 330 and possible BMD capability down the road. So if not APAR Block 2, then what? Cheers!
