Interesting that LO claims above: "...Sean Stackley, the USN acquisition boss, warned the UK against switching back to the F-35B..."
Whereas this - I guess - is the article where there is no such warning from Stackley (only 'a defence source'):
"...“This letter could be a warning shot saying if you Brits go back to jump jet carriers then there might be no planes to fly off it,”
said a defence source...."
Aircraft carrier costs will be half what you think, US tells ministers - Telegraph
