The closing assessment places Imperieuse and Warspite among the Royal Navy's more capable cruisers of their date, while acknowledging their roughly £650,000 cost and flawed belt placement. They were transitional ships, designed for a brig sailing rig just as the Royal Navy's expanding network of coaling stations made that endurance measure unnecessary. The Orlando class combined ideas from the Mersey and Leander types with experience gained from Imperieuse and Warspite. In that design sequence, an imperfect class still advanced cruiser development by testing how armour, machinery, armament, and global support worked together in service.
