In April 1916, during the construction of the HMS Cavendish, it was decided to finish her as a carrier.
By the early 1920s it was decided to convert the HMS Vindictive back into a cruiser as the ship saw very little use as a carrier.
There were four coal fired and eight oil fired boilers.
The forward flight deck was for takeoffs and the aft for landings.
On the upper deck were two hangars with the forward one having derricks to lift aircraft up onto deck, and the aft hangar had a lift.
