Which hull numbers correspond to the Seawolf-class submarines?

• A. SSN 21; SSN 22; SSN 23
• B. SSN 20; SSN 21; SSN 22
• C. SSBN 726; SSBN 727; SSBN 728
• D. SSN 774; SSN 775; SSN 776

Answer: (A)

Hull numbers link submarines to their class and tell you which boats belong in that group. The Seawolf-class consists of three fast-attack submarines with sequential hull numbers: SSN-21, SSN-22, and SSN-23. Those numbers identify the three ships in the class (Seawolf, Connecticut, and Jimmy Carter). Other numbers belong to different classes—ballistic-missile submarines use SSBN designations and different ranges, while Virginia-class boats carry higher numbers like SSN-774 and up. So the numbers that correspond to the Seawolf-class are 21, 22, and 23.
