Assuming that's correct would you happen to remember what the total development cost for the Tornado IDS was? I'm assuming that the UK shouldered the whole cost of the ADV since it was almost solely for them.
Edit: A quick search has the RAF Historical Society's Birth of Tornado giving a cost of £345 million with the UK's share of that being £166 million according to a government statement in late 1974 shortly after the first prototype had flown.
I was wrong. It wasn't 48%, it was 47.6%.
I was thinking of the following quote from page 219 of the British Aircraft Corporation by Charles Gardner
The shareholding in Panavia remained at nationalisation, at least officially. at 42.5 - 42.5 - 15, but in May 1976 Mr William Rodgers of the Ministry of Defence said in Parliament that the UK's share of the total programme was really 47.6 per cent
This is a précis of the preceding two and a half pages.
On 14th May 1969 Dennis Healey announced in the House of Commons that the UK, West Germany and Italy had signed a Memorandum of Understanding and the hope was that the Dutch government would sign in a month or two. The countries co-operating were likely to require over 1,000 aircraft, of which the RAF stood to take about a third. He also said that it was proposed to introduce it in 1976.
He then went to an unofficial press conference. He didn't say what the total R&D bill was estimated to be. However, he did say that the UK's share would be about £150 million, Germany's nearly £200 million, the Italian share would be less than that of the UK, and the Dutch very much smaller. The unit cost per aircraft would be a bit over £1.5 million for the RAF two-seater version (at this stage a single-seater and a two-seater were both proposed). If the Netherlands came in, the total initial production would be some 1,285 aircraft as follows:
600 Germany
385 UK
200 Italy
100 Netherlands
By March 1970 the single-seat Panavia 100 had been abandoned and the numbers had been adjusted to 900 aircraft as follows:
400 Germany
400 RAF
100 Italy
Projected R&D cost had fallen from £410 million to £320 million, as there were now only 7 prototypes instead of 13 and 6 pre-production aircraft instead of 30. The initial shareholding of Panavia had been 49% Germany, 34% UK and 17% Italy. The new division became 42.5% Germany, 42.5% UK and 15% Italy.
As the project progressed there were further changes in procurement as inflation stepped up the costs, and the "split" eventually became:
385 UK (220 strike and 165 ADV)
324 Germany (all strike)
212 Luftwaffe
112 Marineflieger
100 Italy (standard strike and air superiority)
This gives a total of 809 aircraft, 805 of them "new", and four being modified from pre-series aircraft.
