They have a crew of 129 personnel and are capable of operating at depths of up to 800 feet.

2. Virginia-Class Submarines

The Virginia-class submarines are the newest class of attack submarines in the US Navy, with the first vessel, USS Virginia (SSN-774), commissioned in 2004. These submarines are designed to replace the Los Angeles-class submarines and are equipped with advanced technology, including air-independent propulsion, advanced sensors, and unmanned underwater vehicles. The Virginia-class submarines have a length of 377 feet, a beam of 34 feet, and a draft of 29 feet. They have a crew of 135 personnel and are capable of operating at depths of up to 800 feet.

3. Ohio-Class Submarines

The Ohio-class submarines are a class of ballistic missile submarines that were built between 1976 and 1997. These submarines are designed to carry intercontinental ballistic missiles and are equipped with Trident II missiles, which have a range of over 6,000 miles. The Ohio-class submarines have a length of 560 feet, a beam of 42 feet, and a draft of 29 feet. They have a crew of 155 personnel and are capable of operating at depths of up to 800 feet.

4. Seawolf-Class Submarines

The Seawolf-class submarines are a class of attack submarines that were built between 1989 and 2005. These submarines are designed for anti-submarine warfare, anti-surface warfare, and reconnaissance. They are equipped with torpedoes, Harpoon missiles, and Tomahawk land-attack cruise missiles. The Seawolf-class submarines have a length of 353 feet, a beam of 40 feet, and a draft of 29 feet. They have a crew of 140 personnel and are capable of operating at depths of up to 800 feet.

5. Columbia-Class Submarines

The Columbia-class submarines are a class of ballistic missile submarines that are currently under construction. These submarines are designed to replace the Ohio-class submarines and will be equipped with intercontinental ballistic missiles. The Columbia-class submarines will have a length of 560 feet, a beam of 43 feet, and a draft of 29 feet. They will have a crew of 155 personnel and will be capable of operating at depths of up to 800 feet.

🚢 Note: The construction of the Columbia-class submarines is a high-priority project for the US Navy, as it will ensure the continuation of the country's nuclear deterrent capabilities.

Here is a summary of the five US Navy submarine classes in a table format:

Submarine Class	Length (feet)	Beam (feet)	Draft (feet)	Crew
Los Angeles-class	362	33	29	129
Virginia-class	377	34	29	135
Ohio-class	560	42	29	155
Seawolf-class	353	40	29	140
Columbia-class	560	43	29	155

In summary, the US Navy operates a diverse fleet of submarines, each designed for specific missions and roles. The Los Angeles-class, Virginia-class, Ohio-class, Seawolf-class, and Columbia-class submarines are all unique and play critical roles in maintaining the country’s naval presence and defending its interests.
