RSRDC is working as designed

The convoy in question is C 1944/05/13 11+4 from 44b_Jap_Convoys.mis. Within that convoy are 11 Merchants and 4 escorts. These escorts are 2 Type A/B Coastal Defense Ships and 2 Type C Coastal Defense Ships. The configuration date for this convoy is set to March 1 1944, which means that all weapons and sensors within the *.sns and .eqp files are set to that date.

If you review the .sns file for the Type C CDs you will note that they do not receive a Type93-5A Active Sonar until 19440401. The Type A/B CDs receive a Type93-5A Active Sonar on 19430801, however due to a typo in the .sns file the active sonar does not become active until March 31 1944. There for none of the escorts have active sonar

If you want to fix the problem for the Type A/B do the following

Edit Data\Sea\NCD_TYPEB\NCD_TYPEB.sns

Find:

[Sensor 4]
NodeName=N01
LinkName=NULL
StartDate=1938010
EndDate=19440331

and change it to read

[Sensor 4]
NodeName=N01
LinkName=NULL
StartDate=1938010
EndDate=19430731
