Newport News Shipbuilding builds the stern, habitability & machinery spaces, torpedo room, sail and bow. Electric Boat builds the pressure hull, engine room and control room. Newport News Shipbuilding and Electric Boat each perform work on the reactor plant as well as alternate on the final assembly, test, outfit and delivery. The team has been recognized as the best shipbuilding program in the Navy.|

The most obvious change is the switch from 12 vertical launch tubes, to 12 missiles in 2 tubes that use technology from the Ohio Class special forces/ strike SSGN program. The Virginia's hull has a smaller cross-section than the converted ballistic missile SSGNs, so the “6-shooters” will be shorter and a bit wider. Nevertheless, they will share a great deal of common technology, allowing innovations on either platform to be incorporated into the other submarine class during major maintenance milestones. Net savings are about $8 million to program baseline costs.
The other big change you can see in the above diagram is switching from an air-backed sonar sphere to a water-backed Large Aperture Bow (LAB) array. Eliminating the hundreds of SUBSAFE penetrations that help maintain required pressure in the air-backed sonar sphere will save approximately $11 million per hull, and begins with the FY 2012 boats (SSNs 787-788).
The LAB Array has 2 primary components: the passive array, which will provide improved performance, and a medium-frequency active array. It utilizes transducers from the SSN-21 Seawolf Class that are that are designed to last the life of the hull. This is rather par for the course, as the Virginia-class was created in the 1990s to incorporate key elements of the $4 billion Seawolf Class submarine technologies into a cheaper boat.
The SUBSAFE eliminations, plus the life-of-the-hull transducers, will help to reduce the submarines' life cycle costs as well by removing moving parts that require maintenance, eliminating possible points of failure and repair, and removing the need for transducer replacements in drydock.
The bow redesign is not limited to these changes, however, and includes 25 associated redesign efforts. These are estimated to reduce construction costs by another $20 million per hull beginning with the FY 2012 submarine.
With the $19 million ($11 + 8) from the LAB array and Vertical Payload, and the $20 million from the associated changes, General Dynamics is $39 million toward the $200 million baseline costs goal of “2 for 4 in 12”. While the changes themselves will begin with the FY 2009 ship, the savings are targeted at FY 2012 because of the learning curve required as part of the switch. Recent discussions concerning an earlier shift to 2 submarines per year would result in faster production of the Block III submarines, but would be unlikely to make a huge difference to that learning curve.
The construction of the North Dakota (SSN-784), a Virginia-class submarine, is under way.
The Navy released the first image of the work the newest generation payload tubes for this class of submarine to deliver Tomahawk cruise missiles.
The new Virginia Payload Tubes replace the more costly individual Vertical Launch System payload tubes of the past. Unlike the first 10 Virginia-class submarines that housed 12 Tomahawks in individual VLS tubes, North Dakota will use two of the new tubes to house and launch the same number of missiles. The new tubes will provide the North Dakota with greater payload flexibility because it will be able to house a range of weapon payloads that are too big for existing VLS tubes.
"This shows how much cutting-edge technology is being used in the construction of this sub," said Sen. Byron Dorgan, D-N.D. "It's great to see the progress being made in building this impressive vessel. It's a fitting and proud tribute to all North Dakota veterans."
Over the past few years, Dorgan led an effort for the Navy to name a new North Dakota. He invited Sen. Kent Conrad, Rep. Earl Pomeroy and a number of other distinguished North Dakotans to form the North Dakota Committee, and convinced former Secretary of State Warren Christopher, who was born in North Dakota at Scranton, to be honorary chairman. Last July, that effort paid off.
Until then, North Dakota was one of only five states that had not had more than one ship named after it, despite North Dakota's significant contributions to branches of the U.S. military. The first and only at sea North Dakota (BB-29) was decommissioned in 1923.

He enlisted in the Navy and attended Nuclear Power School prior to being released from active duty to attend Auburn University on an NROTC scholarship. Following graduation, he completed nuclear power training and the Submarine Officer Basic Course prior to assignment aboard Albany (SSN-753) from January 1993 to December 1995. From December 1995 to March 1998 he served on the staff of Commander, Submarine Force U.S. Pacific Fleet as a Command Center Watch Officer and later as the Fleet Intelligence Support Officer. Commander Gordon went on to be the Engineer Officer in Louisiana (SSBN-743) (Blue) from October 1998 to October 2001 where he completed five strategic deterrent patrols. He reported in October 2001 to Commander, United States Pacific Fleet, Nuclear Propulsion Examining Board, where he served as a junior board member on the inspection team. Commander Gordon was assigned as Executive Officer in Santa Fe (SSN-763) from February 2004 to December 2005, completing one Western Pacific deployment. He earned a Master's Degree in Engineering Management from Old Dominion University prior to his departure. Following his tour, he was assigned to Commander, Submarine Development Squadron Twelve as a Deputy Commander for Readiness from January 2006 to July 2006. Commander Gordon graduated from the Naval War College in June 2007, earning a Master of Arts degree in National Security and Strategic Studies, as well as completing Joint Professional Military Education Phase II. He served as the Deputy Branch Head for Capability Assessments and Lean Six Sigma (N126) on the OPNAV staff from July 2007 to December 2008. He then served as Deputy Commander for Readiness on the staff of Commander, Submarine Squadron Fifteen in Guam until July 2011. Commander Gordon is entitled to wear the Meritorious Service Medal with two gold stars, the Navy Commendation Medal with three gold stars, the Navy Achievement Medal with two gold stars, and various other unit awards.||USN photo courtesy of public.navy.mil via Bill Gonyo.|

This section is one of four sections which will make up North Dakota which is for the crew berthing and auxiliary machinery room spaces. Katie Fowler (in the pink dress), is the wife of Vice Admiral Jeff Fowler (Ret), as the sponsor of the boat. Katie has a very strong North Dakota connection through her husband Jeff who is a Bismarck High School graduate and whose parents continue to live in Bismarck. Over the years Katie has spent lots of time in North Dakota. As sponsor Katie will be involved in every milestone on North Dakota's way toward its active duty as the most advanced submarine in the Navy in 2014.||USN photo courtesy of public.navy.mil via Bill Gonyo.|
