I was under the impression that the Red Arrows are self funded. ie they dont take cash from the defence budget. They are sponsored by various companies and any overseas tour is funded by that country. A quote from the red arrows website:
How much does the team cost to operate?
There is no meaningful answer to this question. The RAF already has the pilots and aircraft so they really cost nothing. The only real saving that could be made by not having the Red Arrows would be the cost of the fuel they use but that is insignificant when set against the advantages accruing from the Team's appearances.
The additional costs of sending The Red Arrows on overseas tours such as the United Arab Emirates and Malaysia in the autumn of 1997 and 1999 and Canada in 2002 were entirely borne by British companies. The Ministry of Defence takes the view that British tax-payers should not bear the cost of these overseas tours. However it is happy for The Red Arrows to demonstrate the “Best of British” overseas when the companies that stand to benefit are willing to pay the bills.
So there you have it. They will always be with us.
