Tristan Osborne, Labour MP for Chatham and Aylesford, inquired about measures taken by the Ministry of Defence to bolster the UK’s involvement in the international F-35 Lightning II programme, according to a written question and answer.
Responding on 5 February 2025, Minister of State for the Ministry of Defence, Maria Eagle, emphasised that “The F-35 programme is not a workshare programme. It is a competitive international supply chain where F-35 work is won and secured on merit.” She added that “The UK has been successful in securing F-35 work to date and are well placed to secure work in the future.”
Citing data from Lockheed Martin and the Joint Program Office, Eagle noted ta somewhat disputed figure, “approximately 15% of every F-35 aircraft delivered globally is manufactured by UK companies.”
She highlighted a range of F-35 components produced in Britain, including rear fuselages, batteries, ejector seats and actuators, stressing that the UK’s design authority for these parts “secures highly skilled jobs within the UK and provides significant economic benefit.”
The minister confirmed that the domestic contribution involves “over 100 UK-based Tier 1 suppliers and has created over 20,000 jobs in the UK.”
Although the programme does not operate on a formal workshare basis, the government remains confident that British industry will continue to compete successfully for future contracts to support the global F-35 fleet.

The UK is a Tier 1 Partner in the programme. Surely that should guarantee some leverage in supply?
I note Australia has all their 72 F-35A’s. Whereas the UK is bimbling with just 35 aircraft.
Another programme where the UK has invested a lot but come worse off than others. It is like a project run by the French!
If we had all 72 then something would have had to go to pay for the purchase, pilot testing and running costs.
Budgets are just too tight.
Going from 2.3 -> 2.5% sounds a lot but is about £4-5Bb/yr
So each service gets £1Bn after overhead and NE eat their shares.
So what does £1Bn/Yr buy you? That has to include the increased running costs too.
OK a lot of running costs are non linear but are tested as linear when dealing with the pitiful number of anything UK now has. Essentially everything is being run below the optimum point on the economy of scale curve. There is an upper bound too where mass starts to add layers of bureaucracy.
The UK chose to forgo early deliveries at the request of the USMC and to the relief of the MOD budget.
Aah I was about to say that supply of the B version was restrained and that even the Marines were not getting them as fast as planned. Had we ordered some A versions I suspect we could have had plenty of them… IF we had wanted them. I suspect the current scenario suits the Govt while protecting us from being accused of not fulfilling commitments.
Also to UK advantage to take TR3 new build rather tthan earlier batches then have to upgrade with operational impacts too.
To be fair their Hornets/Super Hornets were getting to end of life for the most part. We have a core Typhoon force that’s our workhorse with a lot of life left in it yet whatever the argument oaround ordering more.
DM hates anyone else commenting on here. He has just got many posters deleted. FUCK OFF DM. lol.
And most of Australia’s F35s will require major upgrading. The benefits to the UK go well beyond the number of aircraft on order in service.
Yes, we paid good money back in the day for Tier 1 status. I don’t believe we have such a facility here though, apart from the Sealand site for the avionic side.
“range of F-35 components produced in Britain, including rear fuselages, batteries, ejector seats and actuators” i find it hard to believe that this work represents 15% of the workshare/value on all F35 variants.
This may have been true in the early days of the JSF program when it was in development and there were plans for a UK F136 engine, which ended up being cancelled.
The real money is in the engines, avionics and weapon systems. Furthermore the biggest cash cow is lifetime upgrades & maintenance (easily 2 to 3 times the flyaway costs), not in rear fusleage pieces etc… even the wings represent more workshare than those pieces.
Possibly other items UK made but secret.
I suspect there is some muddying with parts made by uk companies in the US or even elsewhere.
There was a really interesting article a couple years ago from Francis Tusa (who knows his onions about the uk aerospace industry). He did some detailed analysis, and reckoned the UK input into the F35 was more in the 8 to 9 % range…
I reckon that is probably more like it though has probably varied during the programme. I was checking the lift system for example as RR has overall responsibility for it but which seems a complicated blend of interests. Though not RR in concept design (Lockheed originally) they took over responsibility for it early on and overall development occurred in Bristol then further through Allison and now shares parts between its uk and American sites with final build in the US so what share do you give that I wonder, obviously changed over time too.
The F136 involved Rolls Royce but not the UK.
Don’t think that is quite true RR entered the programme before Allison was absorbed and designed the fan for the engine GE and Allison the rest.
