Any idea when we can expect the footage on Discovery?

Sounds like the X-craft!

One of the reasons a Dutch sub skipper thought of the snorkel
was for just this reason.   A submarine in the East Indies -- where
the Dutch k-boats spent their lives -- would turn into an oven 
during the day on the surface.   Submerged and running a diesel
is cooler than running on electric surfaced.

Speaking of color, what's a good one?   Given that the boats are low,
white or silver might not be visible if there are any waves.  How about
a light pink?
