SSN 774 Virginia

Initial Operational Capability (IOC) : October 23, 2004
Total Production : 66
Total Cost : USD $127 billion

The SSN 774 Virginia are the next generation US Navy (USN) nuclear-powered fast attack submarines designed to meet the 21st century submarine warfare requirements. The Virginia class ships are intended as the replacement for existing Los Angeles class attack submarines. These submarines feature advanced technologies to achieve improved firepower, maneuverability, endurance and emphasizing integrated acoustic and non-acoustic stealth. They are able to stay submerged for up to three months at a time. Powered by a nuclear pressurized water reactor (PWR) can achieve a top speed submerged of 25 knots with a maximum depth of 500 meters. The US Navy plans call for the procurement of up to 30 Virginia class submarines starting in 2004.

The submarine high data rate (Sub HDR) multi-band satellite communication (SATCOM) system is provided by Raytheon. The Sub HDR connects submarines to the above sea world by raising a mast-mounted antenna above the ocean's surface while the boat remains stealthy and submerged at periscope depth. It supports secure data, voice, multimedia, imagery and video teleconferencing via the Global Broadcast Service, the Milstar satellite constellation, and the Defense Satellite Communication System. The FORCEnet capability being inducted to existing and on order submarines allows to communicate using IP/Internet Protocol connectivity. It allows US submarine fleet to quickly and easily share and exchange information for military purposes, while submarine crew can connect to their families back home via email, web browsing, file transfer, etc.

Virginia nuclear submarines are used to seek and destroy enemy submarines and surface ships, intelligence collection, special forces delivery, and land-attack operations using Tactical Tomahawk missiles launched from 12 vertical launch system (VLS) tubes and four 533mm torpedo tubes. They perform the full-spectrum of open-ocean, blue water missions as well as littoral warfare missions. The SSN 774 Virginia class submarines goal is to maintain USN undersea superiority well into the 21st century. In addition to current torpedoes, mines and missiles these submarines will be armed with unmanned underwater vehicles (UUV). Virginia class boats can carry the Advanced SEAL Delivery System (ASDS) underwater vehicle for special forces infiltration.

SSN 774 Virginia

Group : Attack Submarines
Status : Active
Also Known As : Virginia Block I
Origin : United States of America
Contractors : General Dynamics Electric Boat, Newport News Shipbuilding
Initial Operational Capability (IOC) : October 23, 2004
Total Production : 2
Unitary Cost : USD $1.0 billion

On 30 July 2004, Virginia (SSN 774) nuclear-powered attack submarine completed its first open ocean voyage, also called Alpha Sea Trials (AST). The AST included a range of submarine and propulsion plant operations, submerging for the first time, and high-speed runs on the surface and submerged, to demonstrate that the ship’s propulsion plant is fully mission capable. The next test for Virginia were Bravo sea trials in August which played particular attention to the ship's underwater acoustics. The Virginia-class lead ship, SSN 774, was commissioned on Saturday, October 23, 2004, at the Norfolk Naval Base. At that time 10 submarines were under building contract of a planned 30 ships class. Only two hulls were commissioned of this Block I design.

Virginia Block II

Group : Attack Submarines
Status : Active
Also Known As : SSN 776 USS Hawaii
Origin : United States of America
Contractors : General Dynamics Electric Boat, Newport News Shipbuilding
Initial Operational Capability (IOC) : May 5, 2007
Total Production : 8
Unitary Cost : USD $1.4 billion

The US Navy christened the USS Hawaii (SSN 776) boat on June 17, 2006, during a ceremony at General Dynamics Electric Boat, Groton, Connecticut. She was commissioned on May 5, 2007. The third ship of Virginia-class is the first ship of the Block II standard and features improved stealth, sophisticated surveillance capabilities and special warfare enhancements. The nuclear reactor plant powering these boats doesn't require to be refueled during the planned service life of the ship. The US Navy awarded General Dynamics Electric Boat a $1.35 billion contract for construction of the eighth ($1.1 billion for SSN 781) Virginia class submarine and initial funding for the 9th ($208 million SSN 782) and 10th ($40 million for SSN 783) January 30, 2006. This award modified an August 2003 contract covering construction of six boats with the six-ship contract value was set to $8.4 billion. The US Navy commissioned eight Virginia Block II submarines between 2007 and 2013.

Virginia Block III

Group : Attack Submarines
Status : Active
Also Known As : SSN 784 USS North Dakota
Origin : United States of America
Contractors : General Dynamics Electric Boat, Newport News Shipbuilding
Initial Operational Capability (IOC) : October 25, 2014
Total Production : 8
Unitary Cost : USD $1.8 billion

The USS North Dakota (SSN 784) scheduled for commissioning on 25 October 2014 in Groton is the first ship featuring a re-designed bow section to allow larger, more versatile weapons tubes under the Block III program. The USS North Dakota is the 11th ship of the Virginia class and the first Block III boat. The Virginia Block III submarines embody an industry commitment to reduce costs without decreasing capabilities through an initiative comprising a multi-year procurement strategy, improvements in construction practices and the Design For Affordability (DFA) program. The US Navy's plans call for the commissioning eight ships between 2014 and 2019.

The DFA program focuses primarily on the redesign of the submarine's bow, lowering program costs by $800 million, increasing capability and providing the capacity for additional growth at no additional cost. This redesign replaces a sonar sphere with a Large Aperture Bow (LAB) Array and the 12 individual vertical-launch missile tubes with two Virginia payload tubes (VPTs), which will each initially carry six missiles in multiple all-up round canisters. The new LAB Array eliminates hundreds of hull penetrations and replaces transducers with lower cost, life-of-the-ship hydrophones. By nearly doubling the payload space available from 1,200 cubic feet with the 12 vertical launch tubes to 2,300 cubic feet, the VPTs will enable Virginia-class ships to deploy a wider variety of payloads.
