Availability 5" perforated film

Dear gang,

I came across some very interesting military cameras, including a few
prismatic 180 degree panorama cameras. Usually these are designed
for 70mm perforated film, but this time there is also a 5" perforated 
film version offered. 

This of course raises the question which emulsions are still being
offered in 5" by whatever manufacturer....since no film simply means
a paperweight of unprecedented proportions (the 70mm versions
already weight 15kg).

My interest is not just panoramic; 70mm also allows using Kodak HIE & 
EIR infrared....yet the next larger format for HIE & EIR is 9.5" 
perforated, as I have never seen claims of 5" infrared.
But since I also have never heard of 9.5" cameras in this category, 
this makes me wonder whether my overview in this territory might be 
incomplete.

Anyone a good insight of the 5" emulsions still on the market, 
permanently or batch-wise for special applications/orders?
