These are three drawings of the plan view, that depict the fore end of the island at 'flight deck' and 'A' deck level of HMS Illustrious as built in 1940. They are also applicable for HMS Formidable, HMS Victorious and HMS Indomitable, all as built. They were drafted by Alan Raven and are presented courtesy of WR Press. The plan at 'A' deck level is shown first and shows how the 'A' deck platform extended beyond the deck house.
The next drawing shows the same area but one level below, at flight deck level. Again the deck house of the island is shown with an open area enclosed by a screen in front of the deck house. The area under the A deck level platform overhang is open. The side screen height is from the flight deck to 'A' deck level. The side screen runs from point A at the top, on the outboard side of the island to point A at the right, at the aft end of the island.
The last drawing shows the plan view of the loading platform for the pom-pom.
* As eagle-eyed Ray D. Bean has already observed, the labels on the photographs are mislabeled "USS Illustrious" when they should have been labeled "HMS Illustrious". This is the result of error by the editor of SteelNavy, who composed and applied the labels. The labels should read "HMS Illustrious 1940, As Built, Plan of fore end of the island at 'flight deck' and 'A' deck level, Plan by Alan Raven, Courtesy of WR Press"
