I don't remember anyone saying the ZB could be used to navigate to an enemy 
target. In 1942 that was done with DEAD RECKONING! In that period of time 
DEAD RECKONING was the first thing we learned. I was in the USAF during and 
after the Korean war. Our fighters had ARN-6 radio compass systems. The 
major airfields had NDBs in proximity but not necessarily on the field.

The pilots often called the tower for a DF STEER.
