FIGHTER DIRECTION SERIES - COMMUNICATIONS [Main Title]
United States Navy training film illustrating the the very complex network of radio and radar signals, operating at many frequencies transmitted simultaneously, used by United States Navy aircraft carriers. Throughout the film a 'core' animated diagram appears repeatedly onto which the paths of the multitude of signals are superimposed individually as the narrator explains their function. The equipment associated with these signals is illustrated. Very typically American, plenty of good equipment and well-trained operators. It is reasonable to assume the Royal Navy has similar facilities, but on a less extensive scale.
Film opens with an aerial view of aircraft carrier at sea. Aircraft taking off. The communications centre (CIC) is the nerve centre for the whole operation. The function of the CIC is the receiving and passing on of information to the relevant operator or department. Cut to the CIC showing plotting tables, wall charts, radio networks, radar screens, and banks of electronic equipment manned by several technicians. The radar section has detected the enemy, aircraft take off and are guided by the air movement department to intercept the enemy.
The 'core' animated diagram appears showing the communications channels involved thus far. All on-going operations throughout the fleet (aircraft carriers, destroyers, frigates) and in the air, are plotted on the operations board as they occur, using multi channel radio links, ship to ship, ship to land, ship to air and air to air, to provide the data. Thus all the activity on board the ships and in the air is presented to the CIC as it happens.
A large variety of other communication systems are explained with the aid of the 'core' animated diagram. Cut to film of action in the CIC, as a major offensive gets under way. Camera pans to each of the thirty operators and the equipment they are manning. Film closes as aircraft return and land at the end of a successful attack.
The 'Blitz' – from the German term Blitzkrieg ('lightning war') – was the sustained campaign of aerial bombing attacks on British towns and cities carried out by the Luftwaffe (German Air Force) from September 1940 until May 1941.
