All the various Malta designs were "armoured" but not all had an armoured flight deck or hangar as in the Illustrious/Implacable/Audacious classes.
The debate about the Malta class began in 1943 with consideration of whether to adopt a "closed" (British style) or "open" (US style) hangar. A large number of design studies were made of both types. The former had armoured flight decks and hangars and the latter had no flight deck armour, the main armour being on the main deck instead. Studies also involved 4 & 5 shaft machinery layouts.
In Oct 1943 a decision was made to go with the a "closed" armoured double hangar layout, known as Design C. Essentially an enlarged Audacious class. The details were as follows:-
LBP 870ft
LWL 900ft
LOA 950 ft
Beam WL 115.5ft
Beam extreme 136ft
Displacement standard 45,620 tons - 47,740 tons
Displacement deep 57,300 tons
SHP 190,000 for 33.5knots at std disp, 32.5knots deep. 4 shaft.
Hangar deck area 69,800 sq ft
Flight deck area 90,100
Flight deck armour 4" over 1.5" plate.
Hangar sides/ends 2"
Side armour 3"
Decks 4-5"
Aircraft 108.
Lifts 2
I don't ever recall seeing any drawings of this version, possibly because its selection didn't last for long.
By April 1944 the debate reopened. The outcome this time was for an "open" single hangar ship without flight deck armour. The armour was on the main deck, below the hangar deck, to protect the citadel. Again there were various options considered until Design X1 was proposed in late 1944 for consideration. But the war ended before it could be approved by the Admiralty.
It is Design X1 that appears in the drawings, as presented by Tzoli and others above. Its characteristics were:-
LBP 820ft
LWL 850ft
LOA 897ft
Beam WL ?
Standard displacement 46,900 tons
Deep 56,800 tons.
SHP 200,000 4 shaft for 33.25knots at std disp, 32knots deep.
2 lifts on FD and 2 side.
Citadel armour 4" deck & side
Flight deck area 96,900 sq ft
Hangar deck area 56,950 sq ft
