BAE Systems have completed the 250th aft fuselage for the F-35 at their integrated assembly line near Samlesbury.

British industry will build 15% of each of the more than 3,000 planned F-35s (not to mention developing close to 30% of each), generating significant export revenue and GDP growth.

The programme is projected to create and support more than 24,000 jobs across every region of the United Kingdom.

A BAE press release states:

“Manufactured on our state-of-the-art integrated assembly line, the section will be equipped and rigourously tested. Once this is complete, the fuselage will be transported to Lockheed Martin’s final assembly facility in Fort Worth, Texas, where it will be integrated with the rest of the aircraft.”

Jon Evans, Head of F-35 Lightning II Production Delivery for BAE Systems, said:

“Completion of the 250th aft fuselage of the F-35 Lightening II demonstrates the progress we have made and underlines our ability to deliver to the programme. Every part we produce not only benefits our own business and workforce, it also helps create work for 500 UK-based supply chain companies involved in the programme.”

The release continues:

“The assembly facility at Samlesbury is presently undergoing a 4,500m² expansion which is due to be completed by January 2017. When the new facility is complete, it will be capable of manufacturing 160 aircraft sets per year, an increase of more than 150% from current levels.”

It is expected that the UK will build a front-line fleet of four F-35 squadrons with each squadron having 12 jets. A fifth unit, an operational conversion unit, will also operate 12 aircraft.

The structure of the Lightning force is now somewhat clear.

  • 17(R) Squadron is currently based at Edwards Air Force Base in the US and fills role of F-35B Operational Evaluation Unit.
  • 617 Squadron will be based at RAF Marham and will be the first operational British F-35 unit in 2019.
  • 809 Naval Air Squadron will also be based at RAF Marham.
  • 2 more unnamed frontline Squadrons are to be established.
  • 1 Operation Conversion Squadron will also be formed.

In 2015, the UK government’s Strategic Defence and Security Review confirmed a planned order of 138 F-35s, with 23 of them to be available for carrier duties by 2023.

The UK will have an operational fleet of around 63 aircraft which is less than half of the total number of F-35’s that the UK has agreed to purchase

However, as reported by AviationWeek, Smyth pointed out that “the total number would cover attrition replacements and the so-called sustainment fleet, which is defined as additional aircraft required to sustain the fleet to its out-of-service date as well as to cover maintenance. Other UK combat aircraft also have large sustainment fleets.”

The programme is progressing at a steady rate with the Royal Air Force recently starting in-flight refuelling clearance trials of its Voyager tanker with the F-35.

The F-35B’s maiden deployment is set for late 2017 and it’s bound for the Western Pacific. The jet will deploy aboard an amphibious flattop and the US Marine Corps are planning a more powerful escort force to support it, according to Admiral Scott Swift, head of Pacific Fleet, as reported by the Marine Times.

The F-35B has already flown from American assault ships as part of a series of tests, which largely went well.

Additionally, F-35 unit costs have been going down with each successive lot of aircraft and will continue to do so.

I flew Grob 101 motor gliders out of there.

Before they moved to RAF Woodvale, along with those from RAF Sealand. Sadly they were taken out of service, and their return date keeps getting put back.


I believe the commitment is to have 43 in service by 2013. Not 23.


Now I’m typo-ing. I meant 43 by 2023. Too many 3’s.

Was it supposed to roll off or was it an accident…..I think we should be told.

Dennis Fraser

I thought this was an American plane made in America??????

Patrick Mooney

No both made it uk and America

James Gale

Nope. 15% workshare and over 30% of all aircraft built are UK.

Robert Marks

So it’s 30% your fault.?

Seb Haggart

We make up to 30% depending on the type. Don’t believe all the stories about this aircraft. It’s going to a great bit of kit and we very much need it in the RN

Mario Navarro

250th ?????

A lot of people believe the rubbish the media like to spew out about it!
