Electric Boat History
The world’s first and finest submarine builder, General Dynamics Electric Boat was established in 1899 to construct a 54-foot submersible vessel developed by John Holland. Just one year later, the world’s first practical submarine, USS Holland, was accepted by the U.S. Navy, marking the beginning of the U.S. Submarine Force. For over 125 years, Electric Boat has continued our legacy of firsts, designing, constructing and maintaining the most capable submarines to ensure our nation’s defense.
Launched in 1954, the world’s first nuclear-powered submarine, USS Nautilus, was designed and built by the men and women of Electric Boat, ushering in a new era of U.S. Navy history. In the succeeding decades, we have never stopped innovating, delivering ever-more capable and stealthy submarines. This storied history has led to our leadership role on today’s most technologically advanced Virginia class fast-attack submarine, and the next-generation ballistic-missile submarine, the Columbia class, our nation’s top strategic defense priority.
Electric Boat will continue our legacy of innovation because of our shipbuilders. While each of our 23,000 employees brings a unique perspective to this work, our success lies in what they share in common—a dedication to protecting the sailors who operate in the harshest environment through delivery of world-class submarines.
