The Naval Sea Systems Command is comprised of command staff, headquarters directorates, affiliated Program Executive Offices (PEOs) and numerous field activities. Together, we engineer, build, buy and maintain ships, submarines and combat systems that meet the Fleet's current and future operational requirements.

Naval Sea Systems Command (NAVSEA) is the largest of the Navy's five system commands. With a fiscal year budget of nearly $30 billion, NAVSEA accounts for one quarter of the Navy's entire budget.

With a force of 60,000 civilian, military and contract support personnel, NAVSEA engineers, builds, buys and maintains the Navy's ships and submarines and their combat systems.

To accomplish this, NAVSEA manages 150 acquisition programs and manages foreign military sales cases that include billions of dollars in annual military sales to partner nations.

The origin of NAVSEA dates to 1794, when Commodore John Barry was charged to oversee the construction of a 44-gun frigate and ensure that all business "harmonized and conformed" to the public's interest.

Today, the NAVSEA organization has 33 activities in 16 states. NAVSEA strives to be an efficient provider of defense resources for the nation, and it plays an important role in the Navy Enterprise. As a Provider Command, it has the responsibility of directing resource sponsors into the proper mix of manpower and resources to properly equip the fleet.

NAVSEA has the further responsibility of establishing and enforcing technical authority in combat system design and operation. These
technical standards use the organization's technical expertise to ensure systems are engineered effectively, and that they operate safely and reliably.
