NATO logistics doctrine still needs practiced execution

Do allied navies such as those of the United States and United Kingdom practise cooperative logistics?

They are expected to across NATO, although joint logistics and replenishment do not always work smoothly even among experienced allied fleets.

NATO navies are expected to practise cooperative logistics. Common alliance membership does not guarantee that communication, procedures, and equipment will mesh perfectly during an operation. Even well-practised navies can find replenishment difficult. Interoperability is a skill that must be exercised repeatedly rather than assumed from a treaty or shared doctrine.
