Below the Radar

The untold story of how the U.S. Navy trained thousands of radar operators in World War II

2 min read

Just prior to entering World War II, the U.S. Navy had fewer than 400 warships. Even worse, only one-fifth of them were outfitted with radar. Within four years, the nation’s armada was over 2000 strong, and every ship was equipped with radar.

The much-heralded speed of U.S. industry left the military with a large but hitherto undocumented void: the personnel to operate and maintain the complicated electronic devices coming aboard. The U.S. Navy had always operated by line of sight when engaging its adversaries. What good were the fleet’s new electronic capabilities without skilled radar technicians?

You’d expectthe longest and most costly phase in the lifecycle of a software product to be the initial development of the system, when all those great features are first imagined and then created. In fact, the hardest part comes later, during the maintenance phase. That’s when programmers pay the price for the shortcuts they took during development.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
