| | MK 23 Target Acquisition System (TAS) |
 | | The Target Acquisition System (TAS) Mk 23 is a detection, tracking, identification, threat evaluation, and weapon assignment system designed especially for use against high-speed, small cross-section targets which approach the ship either from over-the-horizon at very low altitudes or from very high altitudes at near vertical angles. |
 | | The TAS integrates a medium-range, two-dimensional, air-search radar subsystem; an IFF subsystem (covered in a separate paragraph); a display subsystem; and a computer subsystem to provide automatic/manual target detection and tracking, target identification, threat evaluation, and weapon assignment capabilities for engagement of air tracks. |
 | | The loss of the 1390-1400 MHz band segment under OBRA 93 and the proposed reallocation of the 1385-1390 MHz band segment from military to civilian users will result in an 8 percent reduction of the frequencies available for the Navy’s shipborne radars and the MK 23 TAS. |
