On To The Next Block

摘要

Designers are looking at new capabilities for the fourth block of Virginia-class submarines.rn1. Block III improvements will be leveraged for expanded capabilities.rn2. Design opportunities include payload options, a redesigned sail and electric actuation.rn3. Life-cycle cost savings are essential to fund an increased production rate.rnThe ink is hardly dry on the Navy's multiyear contract for Block III of the Virginia-class nuclear-powered attack submarine and designers are busy preparing for the next version, Block IV, which will include new features and cost-saving measures.rn"Even though we just got a contract and there's been a lot accomplished, there's such urgency on my behalf to get something going as quickly as possible on what we're calling a DFA II - Design-for-Affordability II - in support of the Block IV," said John D. Holmander, General Dynamics' Electric Boat vice president and Virginia-class submarine program manager.
