We've built nice subs, pilotable subs and pilotable submerged subs that can fire torpedoes. BUT can we build an AI submerged sub that will attack surface targets with torpedoes? I think we can do it as an AI aircraft, but I'm wondering if it's worth the effort? Hmmmm...
*See the screenie below. Larry's sub is visible as a shadow below the surface of the water in front of the blimp that is about to drop a depth charge on it. Pretty neat stuff being tested out for Oldwheat (aka Larry Brown). She shows on radar but has no wake. You have to be close to see her 'shadow'.
