The better question: How will Germany use their Growlers w/o Q-99 pods. I haven't seen the terms of the deal, or talked with my NIPO contacts, but there just aren't any extra pods in our (or Australia's) inventory and NGJ FOC timelines push out past 2030. Conventional wisdom is that they'll probably be more of an ES vice EA platform for Germany in the short term. That's still a great capability that nobody else in EUCOM (including the US) will have.
Assume the Q-99 production line is cold then?
Working with/for Brits right now the spelling thing can be a little annoying at times, it gets to be a pain when it comes to paperwork since they have a different way of doing things. Through Aussies into the mix and things get even more interesting.
Working a program with RAN for a UK frigate hull, various domestic Aussie combat systems (radar in particular), and US AEGIS and related core components...everything from Engineering documents to differing classification systems creates interesting headaches.
We may share a similar language (I'll never say "same" anymore), but ironically, I think the JMSDSF and ROKN mirror our policies more closely than FVEY.
