Being the definitive variant of the Comet, it was able to carry between 74 and 81 passengers, fly faster and higher and had a greater maximum take off weight thanks to the more powerfull Rolls Royce Avon engines.
Accidents involving the Comet IV only involved pilot error, instrument failure and a terrorist attack, and none related to the accidents of the earlier variants.
