I guess its a matter of if you can avoid it (ITAR), why not? The replacement for the CH-53 (either CH-53K or CH-47F) is also almost 100% ITAR - but Germany/EU does not have an indigenous heavy lift helicopter production capability, so it doesnt have a choice.
There used to be a plan for a european HTH. Of course to be built by Airbus Helicopters. Well with the usual euro delays and te actual pressing need to replace the old G Stallions, Airbus is out. Well they could always buy Mi-26.
But yeah, there is not really a big mselection on the market for big helicopters.
and as I said, ITAR sound to me like a cheap excuse.
Could you elaborate on the MCX rumours?
in the comments a commenter says that the sales guy at the SIG-Sauer stand at the Day of the Infantry said to him that the MCX has a problem with the "Geschoßvorlagefähigkeit" (which I am not really sure what it is exactly and how that translates into english). It seems to have to do something with barrel steels and production methods as the sales guy is also said to have said that only a russian firm and H&K and its french steel supplier get this right. Yes hearsay, but I am looking into it.
I am now wildly guessing here, but it might have to do with the transition area between chamber and barrel and its interaction with the german issue ammunition. Especially the double core projectiles seem to have special interiour ballistics.
H&K having always access to current issue and test samples, because they manufacture and service current issue weapons. The other contenders do not which has been cited as another disadvantage by SIG-Sauer, because they were not able to test properly. Although in the original tender the BAAAINBw stated that it offers standard issue ammunition at cost.
ring that the MCX has been a banana product like so many other from SIG-SauerUSA, they may have just looked for an excuse to withdraw. *shrug* we will see when more info trickels out.
