I think so too, but could also be one of the SPY1 variants (D or F). Also confusing are the words "fire control radar", as the SPY radars appear to be volume search, not fire control. The Aegis installations I have seen (including the Hobarts) have separate fire control radars ("illuminators"), those being the SPG-62, which are dish radars in the X-band. SAAB Ceros 200 performs this function on the Halifax class.After much consideration, and much googling, I think it is SPY-6. He states "...that's why we fit the solid state spy aegis fire control radar...". To me, he does not say LM radar. And the only solid state spy radar that can be controlled by Aegis, is SPY-6 (that I can find), which is Raytheon's ADMR, likely the EASR radar.
So I think you are correct Calculus, SPY-6 EASR.
EASR is related to SPY6 (uses the same radar modules) but different in that it seems to be designed for either a single rotating or a 3-sided installation, whereas CSC appears to have a 4-face radar. The FFG(X) designs have EASR, and are 3-sided, so I would lean more towards SPY than EASR at this point, assuming the CSC rendering is correct.
EASR: Raytheon: Enterprise Air Surveillance Radar
SPY-6: Raytheon: AN/SPY-6 Air and Missile Defense Radar (AMDR)
