Where the Australian and Canadian Type 26 frigates are built

Are the Type 26 frigates for Australia and Canada being built in the United Kingdom or in Australian and Canadian yards?

They are being built in Australian and Canadian yards.

The answer is direct: the Australian ships are built in Australian yards and the Canadian ships in Canadian yards. The British design therefore travels through local production programs rather than through finished-ship exports. This distinction matters when comparing a common frigate lineage with the separate workforces and shipbuilding systems that deliver each national variant.
