HMS Menestheus (M93) was a Blue Funnel Liner launched in 1929. She was requisitioned by the Royal Navy for conversion to the auxiliary minelayer HMS Menestheus. Then converted to an amenities ship for Pacific service. Returned to Blue Funnel in 1946.
British vs. American ship numbering systems.
Each is in two parts, a letter(s) indicating ship category and a number.
The American system identifies the ship type with 2 or 3 letters followed by a sequencial number of the
ships authorization within that type.
In the Royal Navy a pennant number is the identifier of which there is only one ship
in service with that number. These numbers are reused as ships are decommissioned.
There is also frequently a one letter prefix indicating ship type or flag superior. These were reorganized in 1940 . I am confused by multiple letters for the same ship type and of type letters being changed when transferring between fleets. Sometimes there is a trailing letter, a "flag inferior", indicating
class within a type. The ship types were reorganized to a more rational system post war which is often applied in
later writings to wartime ships. There were also Fleet / Flotilla bands that included ship types and/or classes. Thus
various indicators are found for the same ships in different contempory and post war publications.
All nation's naval services reuse ship names in honor of a predicessor.
In these web pages, there is a practice to use American ship type prefix with the correct national (pennant) numbers.
