ZB-1 Radio Homing Adapter and Security Cover

A significant wartime innovation for naval aviators was the YE-ZB radio system, which enabled aviators to find their aircraft carrier without giving away its position.

The ship broadcast Morse code letters in 30-degree arcs. The aircrew flew a heading assigned to the letter. The signals were modulated so they would sound like static if heard without the ZB-1.
