The Neff-propulsion provision specified one coast-defense submarine of about 150 tons submerged displacement. The $250,000 allowance excluded armor and armament, while the required armament was to be comparable to the C class. The builders had to supply a complete boat to their submitted plans and specifications. Payment would follow completion, satisfactory service tests, and acceptance by the Secretary of the Navy. The provision tied the public payment to an accepted vessel.
