The mission of Commander Submarine Squadron 4 is to equip, man and train Sailors assigned to fast-attack submarines to ensure they are combat-ready and capable of taking the fight to the enemy. Its submarines are able to bring strength, agility, firepower and endurance to the battle space like no other platform in the U.S. Navy.
Submarine Squadron 4 includes Los Angeles-class submarines and Virginia-class submarines. The Navy’s newest class of attack submarine, the Virginia class, was let for contract in late 1998. The Virginia class fully embraces the new strategic concept. It is the first U.S. submarine to be designed for battle space dominance across a broad spectrum of regional and littoral missions, as well as open-ocean, “blue water” missions.
The attack submarines assigned to Submarine Squadron 4 include:
USS Virginia (SSN 774) — Commissioned Oct. 23, 2004, Virginia is the first ship in the Virginia class and the sixth U.S. naval ship to bear the name of the state of Virginia.
USS California (SSN 781) — Commissioned Oct. 29, 2011, California is the eighth ship in the Virginia class and the eighth U.S. naval ship to bear the name of California.
USS Minnesota (SSN 783) — Commissioned Sept. 7, 2013, Minnesota is the 10th ship in the Virginia Class and the third to bear the name of the state of Minnesota.
USS North Dakota (SSN 784) — North Dakota is the 11th Virginia-class attack submarine to join the fleet, and the first of eight Block III Virginia-class submarines to be built. The Block III submarines are being built with new Virginia Payload Tubes designed to lower costs and increase missile-firing payload possibilities. North Dakota is the second Navy ship, and first submarine, to be named in honor of “The Peace Garden State.”
USS Colorado (SSN 788) — Commissioned March 17, 2018, Colorado is the 15th Virginia-class fast attack submarine and the fifth Virginia-class Block III submarine. Colorado will be the fourth U.S. Navy ship to be commissioned with a name honoring the state of Colorado.

PCU Vermont (SSN 792) — PCU Vermont (SSN 792) is currently under construction and is scheduled to be delivered sometime in 2018.
PCU Oregon (SSN 793) — PCU Oregon (SSN 793) is currently under construction and is scheduled to be delivered sometime in 2018.
The Commander Submarine Squadron 12 mission is to provide attack submarines that are ready, willing, and able to meet the unique challenges of undersea combat and deployed operations in unforgiving environments across the globe. We prepare attack submarine crews to fight our nation’s wars. Commander Submarine Squadron 12 strives to find helpful, constructive ways to improve performance through frank, objective assessments that enhance the perspective of command teams. We provide the foundations to build success in our crews. We care for submarine families — particularly for submarines at sea — we are the “stay behind” crew. Each submarine must be able to operate “alone and unafraid” in places our adversaries seek to deny us access. Self-reliance and ownership are the hallmarks of our culture and provide the foundation for sustained at-sea operations. Submarines used by Commander Submarine Squadron 12 include:
