Nope. Anything used for national security
needs to be able to be supported within the country where it's being used. Especially in times of conflict. If you source your major system overseas, you have only yourself to blame when they cut off your supply of spares and upgrades.
I was involved in a lot of MCM programs for quite a while. I remember having very similar discussions when Canada
was first working on the specifications for the MCDV program. I made a few trips out to MacDonald Dettweiler in BC working on this stuff. Our underwater acoustic tracking system was installed on those, and I was product manager for that system.
I asked the Canadian Navy
people at the meetings why they were building steel
boats with degaussing coils in them when the entire rest of the world was pretty much going with low-magnetic designs. I had just spent a couple weeks on the HATs and SATs with the Italian Gaeta class in La Spezia, and I was WAY impressed with the Italian boats. The Canadian answer was national security
did not ( at that time) have the capability "in house" to build FRP hulls big enough, so they went with steel
. Just so they could be sure they could get parts
, or more boats, when they wanted them.
There are a lot of other reasons to source these things from home, but that's an overriding one. To control the supply and design.
It's also a whole lot easier to keep the new secret stuff secret when people on the other side of the world are not involved in the design, but that's another thing entirely.
