Irony
I'm not sure if 'upside down,' or 'inside out' is the better description of what's going on.
Not really ironic. Germany has traditionally been a big supporter of Israel out of a sense of duty following WWII.
The Israeli Navy is the big beneficiary. They’ve been equiped with top of the line German subs for years.
As to these destroyers, I wonder what the fit is going to be? The pic above shows an Oto 76mm gun and a RAM mount forward. Maybe Sea Sparrow (VLS) aft?
