The algebra of airlift

This paper describes fundamental algebraic relationships that characterize the movement of cargo and passengers via strategic aircraft that comprise an air mobility system. In particular, we present formulae for computing the number of airlift missions required to deliver a given force a given distance; relationships for estimating the throughput or average daily tons that can be delivered to a particular airfield based on that airfieldʹs operating characteristics; and formulae for estimating the force total closure time based on airlift fleet parameters and the intended operational scenario. We also provide a methodology to compute million ton-miles per day (MTMs/D), a common metric for conducting air mobility analyses and force structure capacity assessments.
