 The Navy Tactical Data System (NTDS) was an early transistorized military fire control computer. Computer pioneer Seymour Cray designed the machine in 1957 while at Remington Rand Univac, just prior to joining Control Data Corporation. The Navy Tactical Data System (NTDS) was an early transistorized military fire control computer.

 This armored computer was extremely reliable in hazardous environments and could control battleship radar and weapons systems in real-time. Multiple computers could communicate with each other to form a cooperative chain of machines. Over the next three decades, the NTDS served as the basis for an entire family of shipboard command and control computers.###​ This armored computer was extremely reliable in hazardous environments and could control battleship radar and weapons systems in real-time.
