L’introduction de l’électricité dans la marine militaire, 1880 – 1935

Abstract : From 1880, the photoelectric projector contributed to the protection of battleships against torpedo boats, paving the way for multiple on-board applications. As electricity spreads ashore in the form of socio-technical networks, the electrification process of military ships interacts strongly with naval weapon innovations. After the diffusion of interior lighting, many servitudes leave the steam engine for electromechanical devices. In the service of the military mission, these uses are energy consuming and the control of the technical system becomes imperative, its reliability being an issue in combat. Around 1910, the complexity of the tool revealed a specific professionalism, essential for everyone to have access to an energy that had become essential. The electrician's know-how is based on training schools and experience gained, with the crew and their hierarchy independently adapting skills to their environment. During this period, the different maritime cultures of the fleets facilitate or hinder the electric motorization of the armoured turrets. Thus, only the US Navy experiments with electric propulsion and does not generalize its use. Naval artillery is the ultimate conquest of this young energy, but two difficulties hinder this electrical technical system: direct current limits the performance of generators and power servoing lacks conceptual models to deal with feedback loops. In 1930, electrical energy, which had become a must on board, made an essential contribution to naval weapons.
