You can judge people by what they say. Donald Trump's Secretary of Defence Pete Hegseth said while hosting Australian Defence Minister Richard Marles, "It enhances our ability in the subterranean space..." in relation to new submarines.
Subterranean submarines wouldn't be very mobile as the soil they would be under would be restrictive. Hopefully Australia actually has bought the 'sub-marine' submarines.
It's going to be a long and interesting four years of the Trump Presidency.
