No Damned Computer is Going to Tell Me What to Do – The Story of the Naval Tactical Data System, NTDS

This is an excellent (and extensive) history of the Navy’s Naval Tactical Data System (NTDS), the computerized mapping of threats. I worked with NTDS in the Navy but never knew how its development not only revolutionized naval warfare but also spurred the development of modern digital computers.

It was 1962. Some of the prospective commanding officers of the new guided missile frigates, now on the building ways, had found out that the Naval Tactical Data System (NTDS) was going to be built into their new ship, and it did not set well with them. Some of them came in to our project office to let us know first hand that no damned computer was going to tell them what to do. For sure, no damned computer was going to fire their nuclear tipped guided missiles. They would take their new ship to sea, but they would not turn on our damned system with its new fangled electronic brain.

We would try to explain to them that the new digital system, the first digitized weapon system in the US Navy, was designed to be an aid to their judgment in task force anti-air battle management, and would never, on its own, fire their weapons. We didn’t mention to them that if they refused to use the system, they would probably be instantly removed from their commands and maybe court martialed because the highest levels of Navy management wanted the new digital computer-driven system in the fleet as soon as possible, and for good reason.

Secretary of the Navy John B. Connally, a former World War II task force fighter director officer, and Chief of Naval Operations Admiral Arleigh A. Burke were solidly behind the new system, and were pushing the small NTDS project office in the Bureau of Ships to accomplish in five years what would normally take thirteen years. The reason behind their push was Top Secret, and thus not known even by many naval officers and senior civil servants in the top hierarchy of the navy. Senior navy management did not want the Soviet Union to know that task force air defense exercises of the early 1950s had revealed that the US surface fleet could not cope with expected Soviet style massed air attacks using new high speed jet airplanes and high speed standoff missiles.

Scientists have figured out how to shock the salt out of seawater – ScienceAlert

Cool!

Researchers have developed a system that uses an electric shockwave to extract salt and other impurities out of salty or contaminated water, and say it could be scaled up for use in desalination or water purification plants, or be used to clean the vast amounts of dirty water produced by fracking.

Known as ‘shock electrodialysis’, the technique applies an electrically driven shockwave to a constant stream of flowing water. The current interacts with the charged salt particles, causing a stream of salty water to be pushed aside and separated from a stream of fresh water, and these are then funnelled into separate pipes.
