NAME PENDANT LAUNCHED COMMISSIONED  PAID OFF
Warrior R31/RML31 May 20/44 Jan 24/46 Mar 23/48
Magnificent  CVL21 Nov 16/44 Mar 21/48 Jun 14/57

The data in the table below for Warrior was extracted from BR299, a Royal Navy publication dated 1947. Unfortunately the document is out of range for HMC Ships Magnificent and Bonaventure so only Warrior is shown. Photos and specs for some of this equipment can be found in this document .  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.

CLOSED CIRCUIT TELEVISION (CCTV)
As a result of studying training material from David Semple, P2RN3, it was discovered that HMCS Bonaventure was fitted with CCTV around 1955/ 56.  The system was fitted to help support aircraft operations.  Three cameras were set up in total. Camera #1 was fitted in the Air Direction Room (ADR) and was pointed to the Main Air Direction Plot (MADP), Cameras 2 and 3 , installed in the OPs Room (OPS) , were pointed in such a way as to be able to read the plotting tables. It would appear then, that the purpose of the equipment was to distribute tactical  (plot) information to other compartments in the aircraft carrier in real time.

The components in the CCTV system were purchased  from the Pye Radio Works in Cambridge , England. The model numbers were extracted from various drawings within the training handout. THe system  used the NTSC standard (525 lines/30 frames per second)
MODEL TYPE DESCRIPTION / COMMENTS 
2014F Camera  (using 5820 image orthicon). H=18 in' W=15.5 in; Length=25 in; 
Weight = 109 lbs (Image courtesy Museum of the Broadcast Television Camera)
2309 Camera Control Unit
2356 Camera Power Unit for 2014 camera.
2785C Monitor -  14 inch. 
2788C Monitor -  14 inch. NTSC standard

Pat Barnhouse was the electronic maintenance officer in Bonaventure from 1968 to when she was paid off on  3 July 1970.  He  recalls, that the CCTV system was removed in the 1966-67 refit.  Apparently it had failed to deliver on its expectations.
