Welcome to NAVSEA

NAVSEA maintains its commitment to the public and the fleet, continually translating warfighting requirements into combat capability to enable our nation and its partners to project presence in peace, power in war, and maritime access at all times. With the delivery of over 20 new ship classes of battle force ships over the past five decades, NAVSEA has been the powerful “Force Behind the Fleet.” 

NAVSEA Mission

We design, build, deliver, and maintain ships, submarines and systems reliably, on-time and on-cost for the United States Navy.

NAVSEA Vision    

Expand the Advantage

For as long as we’ve been a Nation, our Navy has played a key role in protecting the world’s maritime system. Today, traditional and non-traditional forces threaten our safety both at home and abroad. Our technical and tactical advantage over our adversaries is being challenged as technology advances at a rapid pace. Every campaign requires a clearly stated and shared objective and vision. The overarching objective and vision of the NAVSEA Campaign is to expand the U.S. Navy’s maritime advantage over our adversaries through our people, products, and services.
