Well they did have radios, telephones and radar as well. The fire control systems of battleships and anti-aircraft guns led to massive advances in distributed analogue computing that provided early insights into human/machine interactions as well as the beginnings of system-level architecting. The Brits during the Battle of Britain exploited telephone networks and switchboards in innovative ways to create a highly fault (bomb) tolerant decentralised command and control system that formed an early version of the sensor-to-shooter kill chains we see today.
