WASHINGTON ― Courtesy of BAE Systems, some Virginia-class submarines will be able to pack a bigger punch.
The U.S. Navy has granted a contract to British company to produce payload tubes for two of the service’s Block V Virginia-class subs. Each will be extended in length with an additional mid-body section to create additional room for payloads and, in turn, for greater firepower.
One large-diameter payload tube can store and launch up to seven Tomahawk cruise missiles. The four new tubes per sub will add to the existing firepower of the two large-diameter, 87-inch Virginia Payload Tubes on the bow, each capable of launching six Tomahawk cruise missiles
