The Russian model is more like this in that they build an advanced model and then a 'monkey model' that is simpler and easy to mass produce quickly. The rationale being wars are either over very quickly or grind out over the long term. If the latter occurs they should theoretically be able to scale up faster then their opponent who is still producing their most advance machinery.

I read this in a great PDF doc a while back written by I think an ex Russian officer who talked about this and other strategies like their officer heavy army to allow quick expansion through bringing in civilians. I've not been able to find it again if anyone is familiar.
