GD holds keel authentication ceremony for Virginia class submarine Arizona


According to information published by the US DoD on December 7, 2022, senior Navy leaders, elected officials, and industry partners gathered at General Dynamics Electric Boat’s Quonset Point Facility to attend a keel-authentication ceremony for future Virginia-class submarine USS Arizona (SSN 803).

The submarine will be the first U.S. naval vessel to bear the name Arizona since battleship USS Arizona (BB 39) was sunk during the attack on Pearl Harbor on Dec. 7, 1941.

After being struck with several bombs, Arizona burned for two days and more than 1100 of her crew were lost. The lives lost during the attack are now permanently memorialized by the USS Arizona Memorial, erected over her sunken hull in the berth she has occupied since that historic day.

Per Navy tradition, the ship’s sponsor’s initials were welded onto a steel plate to be permanently mounted in a place of honor on the completed vessel.
Arizona will be the 30th Virginia-class submarine.

Boats in this class can hit shore-based targets with highly accurate Tomahawk cruise missiles and are capable of long-term, stealth surveillance of sea forces, littoral waters or ground targets. Their design also provides for Special Forces delivery and support, mine delivery and minefield mapping, and anti-submarine and anti-ship warfare.

Arizona’s Virginia Payload Module will comprise four large-diameter, vertical payload tubes in a new hull section inserted into the existing Virginia-class submarine design. The tubes enable the submarine to deliver a variety of capabilities, including weapons, unmanned undersea vehicles, and other undersea payloads.

Virginia-class submarines are designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations. They are scheduled to replace older Los Angeles-class submarines, many of which have already been decommissioned.

The USS Arizona will have a length of 460 ft (140 m), a beam of 34 ft (10.4 m), and a draft of 32 ft (9.8 m). She will reach a top speed of 25 knots (46 km/h).

The Virginia class is the first to utilize photonic sensors instead of a traditional periscope. The class is equipped with high-resolution cameras, along with light-intensification and infrared sensors, an infrared laser rangefinder, and an integrated Electronic Support Measures (ESM) array.

Two redundant sets of these sensors are mounted on two AN/BVS-1 photonics masts located outside the pressure hull. Signals from the masts' sensors are transmitted through optical fiber data lines through signal processors to the control center. Visual feeds from the masts are displayed on liquid-crystal display interfaces in the command center.
