Underwater vessel (9)

Ross

I believe the answer is:

submarine

'underwater vessel' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for submarine that I've seen before include "Under the sea" , "U-boat" , "Under the surface" , "snack" , "Underwater (vessel)" .)

I've seen this clue in the Sydney Morning Herald, The Independent and The Times.
