With the Allied cruisers, which Ships have radar, I know Boise does, not sure on other ships. Also was Houston's radar installed? She was supposed to have one installed in early December at Cavite, OTL, but the outbreak of the war prevented it.
TTL, the Boise has SC1 radar. The Houston was supposed to get a CXAM radar but it did not arrive TTL in time for the war (that radar set was sent to Brisbane where it is going to be installed on a ship to be determined later by me (I haven't gotten to that yet). The Houston is on her way home after suffering serious damage in the Battle of Albay Bay
British and other Allied ships will have whatever they had historically at this point
