Thanks Denniss

However the D-4 was not a recce model. As per John Vasco and his book, the situation was confused with regard to the D-1/D-4 model, but from what I can read out of what he says, the recce model D-1 was discontinued and replaced with a long range fighter version and it was those that for some reason was re-named D-4.

I can understand that a recce unit needs all the range it can get from its aircraft, so I don't find it strange as such if C-5 models were modified for greater range and when finished classified for some reason as D-4, but it would be nice to get a confirmation this really happened.

Cheers
