BAGNOLET, France, June 22 (UPI) -- F21 heavyweight torpedoes by French naval defense company DCNS are being powered by silver oxide-aluminum electro-chemical battery stacks from Saft.
The silver oxide-aluminum electro-chemical, or AgO-Al, seawater-activated stack delivers the high power needed to propel the torpedo at a top speed of more than 56 miles per hour over a distance of more than 31 miles, Saft said.
