Plate from the Illustrated London News. The ironclad frigate 'Northumberland' was lauched at Millwall in April 1866, used by the navy for defense purposes, then cONVERTED TO A TRAINING SHIP IN 1904 AND RENAMED aCHERON BEFORE BEING SOLD IN 1927. wITH EVER-INCREASING SIZES and weights, lAUNCHING SHIPS WAS BECOMING MORE COMPLEX by the mid-nineteenth century: THE Great Eastern had taken over three months to launch, finally using a series of hydraulic rams. Here the 'Northumberland' is DRAGGED INTO THE WATER BY A SERIES OF SMALLER SHIPS, mainly steam paddlers.
