The price tag attached to Britain’s next generation F-35 fighter jets is expected to rise dramatically. The controversial aircraft is in urgent need of an upgrade at a time when the British pound continues to fall in value.

The UK Ministry of Defence (MoD) will pay around £80 million ($103 million) more for its F-35s, which have faced widespread criticism due to a number of technical mishaps, undermining their performance in almost every key area.
