undersea

Last year, with help of the Royal Navy, an RAF P-8 monitored the Russian spy ship, Yantar, which was reported to be hovering over undersea cables in the Irish Sea.

The Aukus pact also commits the three allies to work together on technologies such as hypersonic missiles, quantum computing and undersea weapons, all of which could be crucial if there is a conflict over Taiwan.

This involves sharing military expertise in areas such as long-range hypersonic missiles, undersea robotics and AI.

In addition, an undersea cable connecting Greenland and Denmark will be funded.

That will include ships to monitor and protect undersea cables and pipelines, possibly of a size that Ferguson's is well-suited to build.
