Were G3 and N3 bargaining tools at Washington?

Were G3 and N3 announced to get American and Japanese building programmes cancelled at Washington?

That explanation is rejected in favour of the view that the Royal Navy hoped to obtain four ships of each design.

The preferred interpretation is that the Royal Navy wanted to build G3 and N3. Its ideal treaty outcome would have permitted four ships of each design. That would have supplied eight new capital ships. The suggestion that the designs were primarily bargaining tools to cancel rival programmes is rejected.
