Engineering notes: General arrangement of machinery as

General notes: Emergency War Programme ships. Original
cruiser design formulated by Lord Fisher in 1915, with a view
to Baltic operations - hence the shallow draught. The lines are
remarkably fine. On trials, Courageous met heavy weather
and was driven into a head sea, straining her hull forward. Doubling
plates were added here, and subsequent trials showed the defect
had been overcome. Glorious strengthened in the same way
a year later as a precautionary measure. No figures are available
as to cost, but they are said to have run to three millions apiece.
Furious, of slightly modified design, was converted while building
into an Aircraft Carrier. Courageous amd Glorious taken in hand
for similar conversion Devonport (June, 1924 and Feb., 1924 respectively).
Work on Glorious was started at Rosyth, but on that yard being
closed she was towed to Devonport for completion. Courageous
completed March, 1928, her conversion having cost £2,025,800.
Glorious completed January 1930.
