Description

The Naval Tactical Data System (NTDS) was originally developed to organize anti-aircraft warfare, but in the mid-1960s, it began to be considered for use in anti-submarine warfare (ASW) as well, and the ASWSC&CS (ASW Ship Command and Control System) project was initiated.Шаблон:Sfn As part of this project, a console with greater versatility than the SYA-4 used by the early NTDS was required.Шаблон:Sfn The UYA-4 was developed in response and was designed around 1965.Шаблон:SfnШаблон:Sfn

The UYA-4 series was the first NTDS display subsystem to employ electronic circuits as integrated circuits instead of individual components such as transistors, resistors, and diodes.Шаблон:Sfn The basic model is the OJ-194/UYA-4, which has a 12-inch plan position indicator, six buttons with fixed functions, and 18 variable-action buttons (VABs), allowing switching between 45 operational modes.Шаблон:Sfn

This series also included table type consoles (operations summary console, OSC) with a large 20-inch PPI scope arranged horizontally so that the screen could be viewed from three sides:Шаблон:Sfn initially the OA-7981 and later the OJ-195 and 197 were used.Шаблон:Sfn

In addition, the OA-7980 was also included to process information about the altitude of targets by obtaining information from 3D radar and other sources.Шаблон:Sfn

However, the functions of this series were basically limited to operation and display, and information processing was performed by mainframe computers such as the CP-642 and AN/UYK-7. The OJ-197/UYA-4 in particular was expensive to maintain and manage, and was gradually replaced in succeeding systems by the AN/UYQ-70, capable of processing information on its own.Шаблон:Sfn
