What distinguishes a superpower from a global power?

What is the difference between superpower status and global-power status?

In this definition, a global power can sustain conventional influence around the world, while superpower status is tied to a far larger strategic nuclear capacity.

The definition offered here separates reaching a distant place from remaining there with a sustained conventional effect. Global power requires logistics, trained crews, command systems, infrastructure, and deployable ships. Superpower status is instead defined through vast strategic nuclear destructive capacity, so the two categories do not automatically overlap. In this assessment, China has theoretical conventional reach, but the ability of its support network to sustain distant operations remains in question. France and, with explicit reservations, Britain are included among global powers. Conventional global-power status is also linked to the original logic of permanent United Nations Security Council membership. The discussion emphasizes that ships, crews, and support arrangements take time to develop.
