Reminds me of  a similar military "first" in the UK.

A friend of mine, who I recently quoted about submarine design stuff,
previously worked for a large British Company, with the same name as some
Italian that invented radio! While there, he was involved in designing a
monitoring system for weapons firing results from a military helicopter.
This involved a video camera mounted on the helicopter videoing the
trajectory of a missile fired from the same helicopter. In the helicopter
was a PAL recorder, but the camera was a "special", his words, with RGB
output. Asking various questions I established that it was regular 625/50
interlaced RGB. Despite my suggestion that PAL encoders were available from
many companies, including a non military division of his company, he later
proudly told me that they had spent 6 months designing an encoder to
convert the camera output to PAL!  And apparently it was not that good.
Now that's what I call stupid and a waste of my tax.

Cheers
