The keel of the 16th Virginia-class attack submarine, named after the 16th largest state, was laid May 16 at Newport News Shipyard. She is the third ship to bear the name Indiana, and will be the first in almost 70 years to sail under the national colors with that name. It is said in the Navy Times that the ship’s sponsor, Diane Donald, the wife of retired Admiral Kirk Donald, a former director of Naval Nuclear Propulsion, declared the keel «to be truly and fairly laid». Diane Donald authenticated the keel with her initials, which were welded onto a metal plate and permanently affixed to the ship.
Construction on Indiana, the sixth of eight Block III variants, started in September 2012. The state is known as «the crossroads of America», and its namesake honors that motto well. She carries millions of parts from 5,000 suppliers located in all 50 states. Assembling these parts is what Jim Hughes, vice president for Submarines and Fleet Support, called «one of the biggest orchestras in the world». The symphony carefully played by 4,000 shipbuilders will now unite hull sections into a 377-foot/114.8 m military masterpiece that will crescendo with its 2017 commissioning, then slip into three decades of silent service.
Her missions will be many and multifaceted. The Virginia class has a large lock-in/lock-out chamber, and a reconfigurable torpedo room to accommodate more snake eaters. She will carry roughly three dozen Tomahawk cruise missiles. Traditional periscopes have been replaced by photonics masts with high-resolution cameras and infrared sensors. A fly-by-wire ship control system provides unmatched operation in shallow littoral areas.
While the Virginia class boasts these and other upgrades in weaponry and other tactical equipment, its biggest edge is in acoustics, said Commander Jesse Zimbauer, the ship’s skipper. Among its many advances, the Block III variant vastly improved passive detection by replacing the traditional sonar sphere with the Large Aperture Bow array. «We are building the future with this submarine», said Jesse Zimbauer, who «jumped on the opportunity» to be part of the pre-commissioning unit.
A keel laying is the symbolic beginning of building a ship, originating from the large structural beam, or keel, that serves as the foundation or spine of the ship’s hull. Although modular construction techniques mean that the ship is no longer built from the bottom up, the keel laying is still celebrated as a momentous event in the ship’s construction. During the keel laying ceremony, the ship’s sponsor authenticates the keel by chalking her initials onto a metal plate. The initials are then welded onto a plate that is permanently affixed to the ship.
