The title is highly confusing. I believed that it was about the Queen (person) owning two physical (land) islands.
But HMS Queen Elizabeth is a ship and the islands are the two towering structures on it.

As a Brit, we generally understand that USS George H.W. Bush is a big ship, not a person. This seems to be the same case from the other side of the Atlantic.
Headlines are inherently not exhaustive in their explanation, that's kind of the point.
FTFY
If "HMS" is ambiguous, than [surely "carrier" is too](https://en.wikipedia.org/wiki/Carrier).
HMS is ambiguous until you add carrier, which gives it just a hint of context.
