The imagined G3 displays British naval power openly, drawing attention to a conspicuous capital ship. Smaller cruisers can exert pressure elsewhere while public attention remains on the battlecruiser. In war, the presence of a powerful ship can reassure merchants and help contain insurance costs, while cruisers and destroyers pursue enemy shipping. The exaggerated dialogue gives those roles distinct personalities. Its practical argument is that a fleet with several levels of force offers more options than interchangeable ships.
