Primary Silver Oxide-Aluminium systems for torpedoes
In the 1980s, the JFP (Joint Feasibility Programme) between France, Germany and Italy was set up to define a new electric propulsion system for heavyweight torpedoes. Silver oxide-aluminium (Ag O-Al) was the selected battery technology as it delivers twice as much energy and power as conventional Ag-Zn batteries for the same mass and volume. Saft is currently the only battery manufacturer able to offer Ag O-Al technology. Saft’s primary silver oxide-aluminium systems suit the requirement of the Blackshark and F21 combat heavy weight torpedoes and MU90 combat low weight torpedoes.
