What's the power requirements for your approach?  

What cameras do you plan to use?

Yeah, you're right.  I think the IR would turn out to be disappointing
except 
in very clear water.  However, it might work if one could project a flare
some distance from the sub, and silhouette objects in the water.  This
gives us the 
image of a tiny sub cruising along submerged, firing flares like a
missile sub.
