ITEM NAME: RADAR SET GROUP
TYPE: AN/GPA-27, AN/GPA-27A, AN/GPA-57, AN/GPA-57A AN/GPA-58, AN/GPA-58A
ΦThese units exist at Radar Set AN/FPS-3A sites. However, these units are required at Radar Set AN/FPS-3 and Radar Set
AN/MPS-7 sites.
‡Antenna Reflector AT-251/FPS-3 requires modification of its associated Antenna Drive TG-9/FPS-3 at Radar Set AN/FPS-3 and
Radar Set AN/FPS-3A sites. Antenna Reflector AT-393/MPS-7 requires modification of its associated Antenna Drive
TG-20/MPS-7 at Radar Set AN/MPS-7 sites.
ffThe nomenclature of the J-754 junction box is changed to the J-951/FPS-20A junction box when the KY-54 code coordinator
is located in the operations building.
fffThe nomenclature of the SB-587/FPS-20 power distribution panel will vary depending on the type of duty required and the
location of the KY-54 code coordinator.
ΦΦWhen magnetic fine grain data equipment is supplied, nomenclature assignment is changed as follows: OA-114,1/FPS-20 to
OA-1629/FPS-20; CY-1976/FPS-20 to CY-2252/FPS-20; and AM-1401/FPS-20 to AM-1767/FPS-20.
