I am glad that I am of the age to have seen ships constructed the old fashioned way. Not all that long ago, shipyards still built ships from the bottom up. The shipyard first fabricated the double bottom sub-assemblies and then started adding framing blocks and so forth. When the hull was fabricated, assemblies welded and painted, they launched the ship down the ways into the water with a satisfying splash, using technology that had been first developed by the ancient Egyptians.
A recent article reminded me of how much things have changed. Ships are now built in large sub-assemblies, welded into blocks, and then the blocks are welded together in drydock. In the case of the new British aircraft carriers, HMS Queen Elizabeth and HMS Prince of Wales, the construction blocks will be fabricated at seven different shipyards. Recently the “lower block three” of HMS Queen Elizabeth, 8,000 tonnes of steel, piping, cable and other outfitting was towed from BAE Systems shipyard on the Clyde in Govan in Glasgow, on its way Rosyth on the Forth, 600 miles away, for final block integration and assembly.
The new British carriers will each cost a budget-busting £2.6bn (US$4.3 billion.) That is still less than half the cost of the USS Gerald R. Ford, the new US carrier under construction, which is estimated to cost US$ 9 billion or US$14 billion if research and development costs are included.
