UTC 156-inch SRMs

[Archibald]

United Technology manufactured Titan III' 120-inch solids.

Thiockol and Lockheed tested 156-inch solids from 1964.

Flight global mention that, back in 1963,UTC tested 156-inch casings.


I know Astronautix mention of UA-156 3- and 4-segment SRMs, but that's not enough


My question is simple : did UTC ever fired a 156-inch SRM prototype for an upgraded Titan III (date would be 1964 - 1968) ?

Every information on 156-inch SRMs and their eventual application to a basic Titan-III core is welcome! (not the enlarged Titan IIIG)

Note on UTC = United Technologies Corporation
befor 1975 they called United Aircraft Corporation short UA

so Archibald looks for the UA 156-inch SRM

i gona look in my archive about UA 156 inch
but take some time
