"award" kann lt. LEO auch "Zuschlag" (bei Versteigerungen) bedeuten. Hier könnte es um eine (mehrfache oder Folge-)Auftragserteilung bei Ausschreibungen gehen.

What is a Multiple Award Contract?

A multiple award contract is one that is awarded to multiple contractors (two or more) for same and similar products and services at same and similar costs. Multiple award does not pertain to the number of buyers ordering from the contract, but, instead, the number of contractors receiving the award from a common bid or negotiation process.

ABER: Damit habe ich noch immer keine schoene, griffige, deutsche Uebersetzung ... Wer weiss es?!:-)

Judith: weissnix's suggestion (...erteilung, not Zuschlag) seems to fit the definition you found which IMO is correct. Such contracts occur often when there are multiple locations and the AF needs to make sure there is a supply of what they need at each site at a fixed price.
