– Breaking Defense – The US Navy has decided to scrap the fire-ravaged USS Miami, whose repair bill from arson had soared to $700 million from $450 million. It’s the first time the Navy has written off a damaged sub since the USS Bonefish burned in 1988, and it brings the attack submarine force down to 54 subs. The most cost-effective way for the country to make up for the loss of the nuclear-powered Miami is to keep the rest of the fleet well-maintained and to keep buying two new Virginia-class submarines each year, the Navy’s director of Undersea Warfare said.
