Rereading the article it seems we're really cancelling the F-35's to pour money into BAe ( a "red-wall" company of course) - it's hard to believe that the Tempest will be ready in less than 10 years and then God knows what the cost per unit will be - and we may have had several changes of Govt by then so its long term prospects aren't brilliant. The RAF wil soldier on with Typhoon upgrades and perhaps the occasional small buy - again good for BAE but its a major cut in planned forces for sure
