USS VIRGINIA (SSN 774)
USS VIRGINIA is the lead ship of the VIRGINIA - class of nuclear-powered attack submarines. The submarines in this class are the first US submarines designed for battlespace dominance across a broad spectrum of regional and littoral missions as well as open-ocean, "blue water" missions. The VIRGINIA - class achieves the right balance of core military capabilities and affordability.

About the Ship's Coat of Arms
Emblazoned on a blue background that symbolizes the mighty deep, USS VIRGINIA is prominently positioned. The forward view of VIRGINIA denotes her leading the Submarine Force into a new century and onto a new and exciting course for the United States Navy. The gold lettering and border around the seal combined with the blue background represent the Navy’s colors of blue and gold. The silhouette of the Commonwealth of Virginia represents the state for which the ship is named. Each of the nine stars represents an American warship named VIRGINIA. The single point of light at the stern of the ship symbolizes both the nuclear propulsion plant that powers the submarine as well as the ship’s data processing system fiber optic backbone. In keeping with the Commonwealth of Virginia’s motto, the words “Sic Semper Tyrannis” (Latin for “Thus Always To Tyrants”) appear at the bottom, which combined with the symbolism of the Commonwealth’s Seal, represents the triumph of Virtue over Tyranny.
The image of George Washington also looks forward with VIRGINIA. George Washington, a Virginia native, has been characterized as the “indispensable man” vital to the formation of the republic. In all of history, few men who possessed unassailable power have used that power so selflessly and wisely for the welfare of their countrymen and all mankind.

Vision
Envolve the VIRGINIA Class to a fully modular, all-electric submarine that will accommodate large modules to provide interfaces for future payloads and sensors
HIGHLIGHTS
• 30 - ship class
• Seawolf Class stealth at a lower cost (30% lower Total Ownership Cost)
• Modular Design & Technology Insertion
Mission reconfigurable modules reconfigurable capabilities.
Submarines of the future will require specialized equipment to maximize their effectiveness in each of the numerous mission areas in which they will be called to perform. Furthermore, future submarines must be able to integrate new technologies periodically without requiring intrusive and expensive redesign. Modular design is the means of meeting both of the above requirements.
Open system architecture and modular designs will allow greater capability and easier upgrades at the component and system level. Payload modules will be used in the sail of the submarine to allow rapid change out of mission specific masts and installation of non-mast sail payloads. Bow and amidships payload sections will allow for larger volume modules that may support deployment of special forces, conducting expanded strike missions, or additional specialized sensors including UUVs. These modular concepts will allow greater mission flexibility. Additionally, modular hull design and construction will also enable greater adaptability, such that future ships may be modified to support new capabilities and configurations at lower cost, with less effort, and in less time
The VIRGINIA Class is designed to support these modular concepts. Additionally it will incorporate a process called Technology Insertion to implement advanced technologies as they become available. Technology Insertion will seek to incorporate both evolutionary and revolutionary technologies in the VIRGINIA Class at the component, system, and module levels. Examples of evolutionary improvements include enhanced electro-optical sensors mast modules with improved standoff range, automated environmental sensing systems, acoustic communications systems, high-frequency sonar upgrades, and affordable array technology components. Some Technology Insertion will occur in pre-designated "bundles" as a means of demonstrating and developing move revolutionary technology to be built into future submarines. Currently envisioned bundles include a conformal bow sonar array that would include new bow modular payloads, an advanced composite sail for additional modular sail payloads, and an electric drive system that will become the standard of future submarines.
• Superior littoral performance and ISR capabilities including:
Unmanned Undersea Vehicles (UUVs)
UUVs allow an SSN to safely gain access to denied areas with revolutionary sensors and weapons. These areas may be denied based on unacceptable risks to an SSN such as extremely shallow water, very poor acoustic conditions, or mined waters. UUVs provide unique capabilities and extend the "reach" of our platforms while reducing the risk to an SSN and its crew.
UUVs are envisioned to contribute to the following SSN mission areas: Mine Warfare (MIW); Intelligence, Surveillance, and Reconnaissance (ISR); and undersea environmental sensing and mapping.
The first UUVs that will be fielded on SSNs will support Mine Warfare. The Long-term Mine Reconnaissance System (LMRS) will greatly improve submarines’ mine hunting capabilities in the near future. Ultimately, a mission reconfigurable UUV will also come into service providing more capabilities and reducing risk to future SSNs. UUVs are key elements in maintaining submarines’ future undersea dominance against any threat.
Improved Sensors
Submarines require sensors that cover a wide range of the electromagnetic and acoustic spectra. Submarines of the future will require even more advanced sensors in order to operate safely and more effectively execute their missions. Several initiatives are underway to ensure that future submarines will continue to have sensors that allow the submarine to carry out all of its missions in the most difficult environments and against the variety of threats that it faces.
Acoustic Rapid COTS (Commercial off-the-shelf) Insertion (ARCI)
High Frequency Sonar
Conformal Sonar Arrays
Submarine Tactical Environmental Data (STED)
Intelligence, Surveillance, Reconnaissance and Targeting Sensors
Unmanned Undersea Vehicles (UUVs)
New communications systems
Submarine communications were once limited to those necessary to communicate mission support information and the minimal command and control that a submarine previously required. The Navy continues to implement the principles of Network Centric Warfare, where the capability of the total force is made greater than the contributions of individual platforms through networking of sensors, weapons control systems, and information systems.
As submarines continue to conduct a variety of missions to include intelligence collection, Indications and Warning (I & W), anti-submarine warfare, anti-surface warfare, strike warfare, and mine warfare, they will have to be an integral part of networked sensors and platforms
Submarines’ future missions will require a revolution in communications connectivity and supporting bandwidth. The vision is to allow submarines to communicate without the current restrictions of depth and speed and with sufficient bandwidth to maximize the effectiveness of data and intelligence collected by the submarine, such that real-time connectivity and reach-back is achieved
The development of these advanced communications has already begun with the incorporation of Narrowband based systems that are IP architecture based. Following this is development of a higher data rate antenna and wideband based communications and ultimately a buoyant cable antenna that allows two-way communications at depth and speed.
Ultimately submerged data exchange and communications capabilities will be a key enabler for employing off-board vehicles, sensors, and distributed networks of UUVs, sensors and other payloads.
