to day the navy department has announced two 22,000 repalcment cairres for HMAS Horbat each cairre are to be built in the comeing year and will have a wing of 70 aircaft on bored the minister for the mr John black could not be reacht for coment at this time the class cairrers will be named
HMAS Maxwell and Steelwell.

Remarks:
Hull space for machinery, storage & compartmentation is adequate
Room for accommodation & workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily
Estimated overall survivability and seakeeping ability:
Relative margin of stability: 1.06
Shellfire needed to sink: 24,527 lbs / 11,125 Kg = 538.3 x 4.5 " / 114 mm shells
(Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
Torpedoes needed to sink: 2.8

'Natural speed' for length: 26.46 kts
Power going to wave formation at top speed: 53 %
Trim: 56
(Maximise stabilty/flotation = 0, Maximise steadiness/seakeeping = 100)
Estimated hull characteristics & strength:
Underwater volume absorbed by magazines and engineering spaces: 96.5 %
Relative accommodation and working space: 148.1 %
(Average = 100%)
Displacement factor: 125 %
(Displacement relative to loading factors)
