Here is a couple of very good links.

These guys say that there Korts nozzles are better then the Rice nozzles. It looks like they are going to make use work for it.

The Deep Flight Aviator DF-502sub was using, I believe Kort nozzles. There site states that the sub has already been retired. 
 
"The experimental prototype Deep Flight Aviator has been de-commissioned. The submersible is being replaced by the state of the art Deep Flight Super Falcon submersibles, which offer highly advanced safety and operational features, and are currently being designed/built for private clients."

I never saw it go inverted, so as a hydrobatic sub prototype, it must of been missing something important. Still a very cool sub though.
