RADIO FITS FOR 'C' CLASS DESTROYERS


In January 1945, after a year's discussion, the British Admiralty agreed to lend the RCN a flotilla of eight 'C' class destroyers for use against the Japanese.  The war however, ended before any of the eight ships were completed. Only two were transferred, namely Crescent and Crusader . They retained their British appointed names  when commissioned into the RCN. The transfer was made permanent in 1951.

HMCS Crescent and Crusader were virtually identical to Algonquin and Sioux differing principally in having only one set of torpedo tubes and in being armed with 4.5 inch guns instead of 4.7 inch guns.  Upon her arrival in Esquimalt in January 1946, Crescent was immediately paid off and remained in reserve for several years. Meanwhile Crescent carried out training duties until taken in hand for a major conversion.. She emerged  in 1956 as a fast A/S frigate. Crusader saw two tours of duty in Korea.

CRESCENT (R16) CRUSADER (R20)
Launched 20/7/1944 5/10/1944
Commissioned 10/9/1945 15/11/1945
Finally Paid Off  1/4/1970 10/1/1960
The data in the tables below was extracted from BR 299, a Royal Navy publication dated 1947. Both ships are noted as being on loan for the 1947 period.  Photos and specs for some of this equipment can be found in this document including the specs for all 60 series transmitters .  Any numeric suffixes which appear for American made equipment, denote the procurement contract number. A TBL-4 is identical to a TBL-12  but was made under a different contract number or even a different contractor.
