The German defense minister has announced that by the time the Puma not enter service for the problems identified in the five prototypes built, and are waiting for proposals for improvement of the manufacturers to make a decision.What you read is my Google translation of his articles. I'm really loving the S. American blogs because they're in a style that appeals to me (Asian blogs too), the one problem I have is the translation (if you're a Spanish speaker I'd appreciate a verification on this info).
Apparently main problems are electronic systems and software associated with these, but the weight of the vehicle does not seem to convince the Bundeswehr.
Having said all that it appears that the Puma IFV is in a bit of trouble. A quick google search of the German Ministry of Defense and Army websites met with negative results, but the search continues.
But 5 prototypes and problems with the vehicles electronics? That's bad news all around.
