The 2023-built MS American Eagle cruise ship is the first in a 12-ship series (Project Blue/aka Coastal Cat) of catamaran-design newbuilds in the ACL-American Cruise Lines fleet. From this (new for ACL) class are the same designed catamarans/sisterships launched two per year - in 2023 (Eagle/August, Glory/November), 2024 (Liberty/June, Legend/October), 2025, 2026, 2027, and 2028.

All ACL cruise ships are US-flagged and built by the company-owned Chesapeake Shipbuilding Yard in Salisbury MD (Maryland USA).

Note: The 2023-built vessel (IMO/MMSI numbers 368317840) is not to be mistaken with the namesake "MS American Eagle" (2000-built), which operated under IMO 9270024.
