The Navy will have to upgrade and keep three of four Ticonderoga-class cruisers the service planned to retire in 2013, according to proposed legislation released by House Republicans. The proposal by House Armed Services readiness subcommittee chairman Randy Forbes, R-Va., would keep the Cowpens, Anzio and Vicksburg in the fleet by authorizing needed upgrades. The Navy had planned to retire all three, along with the Port Royal, on March 31, 2013, and three more the following year to meet congressionally mandated budget cuts and to save an expected $4.1 billion.
