AHC: Make liquid propellant standard for artillery

This idea was floated quite a bit in the mid-'80s, IIRC, then seemed to disappear. So what went wrong?

Your challenge: POD 1945 or later, make liquid propellant artillery (LPA?) standard in Western armies (or all "industrial" countries, including SovBloc, if you want) by 2000.

Major changes to the course of OTL wars are out of bounds (unless you can clearly show the introduction of LPA changes the outcome)...but early use of LPA (frex, in 'nam) is fine.

Please, no debate over the merits of certain caliber(s) or national approaches to use of artillery, unless the approach governs the chance of introduction of LPA.

Please, no rants over bad procurement choices, unless that governs the chance of adoption.

Other than that...I welcome vigorous debate. (I haven't a lot to contribute, so I expect more to play "referee" as needed.:))
 
Was never exposed to the engineering for this. When I was on active service in the 80s it was barely talked about. Maybe the R & D was heavily classified then? Sometime in the mid 1990s I started seeing some articles on it. Cant recall any details, but it seems to me they all were addressing it at the theoretical level, with nothing of value to someone who was actually 'doing artillery' at the time. Some time around 2005 the discussion left my view and items like electro guns, or new conventional guns were still discussed.

I'll allow I may have the date wrong... Whatever it is, the challenge stands.
 
This is way outside my realm of expertise, but this article (yes, I know, it's Wikipedia) does lay out the problems that need to be overcome. Seeing as they were researched and developed for over 40 years without a single gun or round ever entering service, I somehow doubt it can be practically done.

That link makes very interesting reading indeed. Thx.:) (Tho the conclusions make me sad.)
