F-35 ABCs: Why Are There Three Variants?

The F-35 fighter jet has three variants, the RAF and Navy are being equipped with the F-35B.

F35 Stealth Fighter Jets

Two of the RAF's F-35B Lightning stealth fighter jets have taken to the skies over the North Sea as part of Exercise Point Blank.

Aircraft from the British, US and French Air Forces all scrambled together to practise what has been described as part of an "insurance policy" against global threats.

F-35B aircraft landed on the deck of the UK's new aircraft carrier HMS Queen Elizabeth for the first time in September.

The landing was completed by US aircraft, flown by British pilots.

UK jets will land on deck when HMS Queen Elizabeth returns to Britain.

It follows a British F-35B aircraft performing its first vertical landing at its Norfolk home in July.

The UK's first variant of the fighter visited RAF Valley earlier this year.

The arrival of Britain's first four supersonic jets at RAF Marham took place in June, with a further five arriving in August.

In November, it was announced that Britain would more than double its number of F-35B aircraft after ordering a further 17 of the jets.

Britain plans to eventually have 138 F-35Bs.

Aircraft ABCs

The F-35 jet has three variants: the F-35A conventional takeoff and landing (CTOL) variant, the F-35B short takeoff/vertical landing (STOVL) variant, and the F-35C carrier variant (CV).

The three variants perform similarly and are mainly distinguished by their different basing requirements. As a result, the F-35B and F-35C have unique ways to take off and land - due to their requirements for short take-off and landing or landing on carriers.

Using much of the same parts across the three variants allows for service-specific aircraft while allowing for savings to be made as a result of parts and processes being common to all three variants.

F-35A

The F-35A is the conventional takeoff and landing (CTOL) variant which is designed to operate from regular runways.

It is the only version to carry an internal cannon.

The F-35A is set to be the common F-35 as the US Air Force and the majority of their our allied air forces and Foreign Military Sales (FMS) nations will operate the F-35A.

Look out for the F-35A in the skies above Suffolk as they are set to receive their first F-35As by 2021, before eventually maintaining two operational squadrons there.

They are not capable of operating from the UK's Queen Elizabeth-class aircraft carriers.

F-35B

The F-35B model short takeoff/vertical landing (STOVL) variant will be used by the Royal Navy and RAF. 

It was designed to operate from austere, short-field bases and a range of air-capable ships - including the Queen Elizabeth class aircraft carriers.

The F-35B can also take off and land conventionally from longer runways at major bases. 

Each 'B' variant of the jet costs around $122.4m - but Lockheed Martin say they expect this cost will be reduced in the future, starting with the F-35A and then moving on to the B and C.

The company said they will drive the 'A' model's price down to $80m.

F-35C

The F-35C carrier variant (CV) is the carrier variant, designed to be the US Navy’s first stealth fighter and the world’s only 5th Generation, long-range stealth strike fighter designed and built explicitly for aircraft carrier operations. 

The F-35C variant has larger wings and more robust landing gear than the other variants, making it suitable for the US Navy's catapult launches and fly-in arrestments aboard naval aircraft carriers.

Its wingtips also fold to allow for more room on the carrier’s deck while deployed.

The F-35C has a greater internal fuel capacity than the other two F-35 variants.
