Hello anonymous, thanks for your input. No, I have not served in any navy, but the term "propeller" is indeed used for both aircraft and ships. The American usage of the word "screw" is the shortened form of the full term "screw propeller".
In fact, even the US Navy does not use the term "screw" exclusively. If I recall correctly, the US Navy has a "Naval Foundry and Propeller Center" in the city of Philadelphia at the site of the former naval base note the usage of the word "propeller" in its proper name. This center's mission is to manufacture and enhance ships' screw propellers.
Hope this information helps!

Thank you for correcting me. I'll have to believe you, you know more about this stuff than I do. I only know what I had been told while in the navy, by a boatswains mate off a ship. I was never aboard a ship I was a Seabee.
That Bismark was quite a ship! What is the diameter of the propellers? Looks to be at least 30'.

Anonymous: No no, I didn't "correct" you. It is a conversation between two military history enthusiasts! We learn from each other :)
According to Wikipedia, the screw propellers are each 4.7 meters in diameter, which translates to about 15 feet and 6 inches.

Apparently the person writing the caption under the pictures was never in the navy. Ships do not have propellers. Ships have screws propellers are found on aircraft.
