The SCR-270 was a mobile early warning radar. Five of the SCR-270B model were deployed on Oahu at the time of the Pearl Harbor raid, and another was operating at Iba in the Philippines. A set was delivered to Henderson Field at Guadalcanal, where it gave the Wildcats just enough warning of Japanese raids to climb to combat altitude.
The Iba set fell into Japanese hands and was shipped to Japan for
further study. It gave the Japanese some of their first indications
that they had fallen seriously behind in radar technology.
