SSN 784 Basics
PCU North Dakota, SSN 784
Construction of PCU North Dakota (SSN 784) started on March 2,
2009, and its contract delivery is in 2014.
It is the second U.S. Navy ship to bear the name, honoring the military legacy of a state that has produced 17 recipients of the Medal of Honor for actions in Combat. USS North Dakota (BB-29) was a 20,000-ton Delaware-class battleship that served from 1910-1923.
North Dakota is the first submarine in the $14 billion Block III
contract awarded to Electric Boat company on Dec. 22, 2008, which covers construction of eight Virginia-class submarines, SSN 784 through SSN 791.
A redesigned bow with two large payload tubes provides the Virginia
Class Submarine with volume and flexibility for the changing mission
requirements of the 21st century, and savies $40 million per hull in the process.
The redesigned bow replaces the ability to launch 12 missiles from
vertical tubes, while at the same time providing a much larger diameter payload capacity - 87 inches instead of the previous 21 inches -significantly increasing the capability of the ship to deploy a much broader range of weapons, sensors, adjunct vehicles and other payloads.
In addition, North Dakota will be the first attack submarine with tubes having a diameter comparable to Ohio-class SSGNs, which means it will be able to leverage investment in payloads for that platform.
Virginia-class submarines provide the Navy with capabilities that will
help it maintain undersea supremacy into the 21st century. They feature improved stealth, sophisticated surveillance capabilities and special warfare enhancements that will enable them to meet the Navy's multi-mission requirements.
The role of attack submarines in the fleet include strike; covert longterm surveillance of land areas, littoral waters or other sea-based forces; anti-submarine and anti-ship warfare; special forces delivery and support; and mine delivery and minefield mapping.
Virginia-class submarines displace 7,800-tons and are 377 feet in
length. They can operate at more than 25 knots submerged, and are designed with a reactor plant that will not require refueling during the life of the ship.
