Removal of stability of model of underwater craft? (10)

Ross

I believe the answer is:

subversion

I'm a little stuck... Click here to teach me more about this clue!

'underwater craft?' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'removal of stability of model' is the wordplay.
'removal of stability of' becomes 'sub' (I can't justify this - if you can you should believe this answer much more).
'model' becomes 'version' (I've seen this before).
'sub'+'version'='SUBVERSION'

'of' acts as a link.

Can you help me to learn more?

(Another definition for subversion that I've seen is " ruin".)
