Deployed physical composant

The breakdown relationship for owning components means “is composed of”. For sub components, it means “is part of”
The deployment relationship is a bit different. If you think about a SW piece of code running on a processor, you don’t really consider the piece of code as being part of the processor. Instead, it is executed by the processor.

Even if my concern is a battery which is part of the power sub-system of a launcher and deployed in the upper stage, I think i understand the usage. thank for your answer.
