I asked for Una Class Hulls on a Car production line, some are ready. Move on to Missile capable mass production. We need to reduce the price which can be 500 m each. These are better than ships & ground forces. Reduce depth, increase range, looking for 200 m. Out of sight will suffice. 40 mph submerged is possible, think Arrow. Affordable to protect Coastal areas from Aircraft, shallow water.
Tow Missiles
A submerging rack of Missiles can protect Coasts from Jets & Cruise & detach to flee a Ship in a hurry, God said.
