– CNN – The past two months have been anything but smooth sailing for the U.S. Navy’s newest class of warship, the littoral combat ship. Troubles for the ships, which cost around $360 million apiece, began in December, when the USS Milwaukee (LCS 5), broke down off the East Coast and had to be towed 40 miles to a naval base in Virginia…Just a month after the Milwaukee mishap, its sister ship, the USS Fort Worth (LCS 3), is tied up at a dock in Singapore with what the U.S. Pacific Fleet calls “a casualty to the ship’s combining gears.”
