Iran and China operate lethally quiet diesel-electric submarines, carrier cripplers and the scourge of the surface fleet. Thankfully, so do navies from such South American nations as Brazil, Peru, Colombia and Chile. And under a seven-year-old agreement with the U.S. Navy, their diesel-electric subs regularly train in fleet exercises as opposing forces.
From Monday through the end of the month, the Theodore Roosevelt Carrier Strike Group and the Iwo Jima Expeditionary Strike Group will engage in Operation Brimstone, their pre-deployment joint task force exercise, off the southeastern U.S., reports the Navy Times.
Italian, French and British naval forces will also participate in Operation Brimstone.
