Early S-band RADAR Designations[51]

Designation Wavelength Platform
CXAM 150-cm large surface ships
SK-1 large surface ships
SK-2 large surface ships
SC 50-cm surface ships
SF 10-cm too heavy for intended use on PT boats, but used on larger ships
SG 10-cm surface ships
SJ 10-cm submarines
SM 3-cm aircraft carriers for direction of night-fighters
SO 10-cm PT boats
SU 3-cm Destroyer escorts

From February 1943 the US used a universal system to identify radar variants, consisting of three letters and a number, respectively designating platform, type of equipment, function, and version. This system was continued after WWII with multiservice designations being prefixed by 'AN/' for Army-Navy. BuShips 1943 classifications

Prefix Designation
A Aircraft, used in combination with other letters
B IFF
C Experimental
D Direction-finding
E Emergency power
F Fire control radar
FS Frequency shift keying
G Aircraft transmitting
H Sonar hoists
I Intercept radar, aircraft only
J Passive sonar, for submarines
K Sonar transmitting
L Precision calibration
M Radio transceiver
N Echo-sounding
O Measuring, for operator training
P Automatic transmitting and receiving
Q Sonar, for surface ships
R Radio receiver
S Search
T Radio transmitter
U Remote control
V Radar display
W Submarine sonar
X Experimental
Y Radar homing beacon
Z Airborne navigational aids, later replaced with ARN and APN
