Coalition C2 Data Sharing

Combined operations live or die on a shared picture, but "shared" has always meant a painful trade: either a nation copies sensitive intelligence into a coalition database it can't fully control, or releasability caution throttles sharing down to whatever can be manually cleared and emailed — and the second happens far more often than the first.

Data Spaces let each nation hold its own data in its own sovereign domain and publish only governed, releasable data products, so a partner queries the agreed tracks and products in place under the owner's policy rather than receiving a copy — the coalition gets one interoperable picture while every contributing nation keeps control of exactly what it shares, with whom, and under what conditions.
