Spaceports have traditionally been characterized by performance measures associated with their site characteristics. Measures such as 'Latitude' (proximity to the equator), 'Azimuth' (range of available launch azimuths) and 'Weather' (days of favorable weather) are commonly used to characterize a particular spaceport. However, other spaceport performance measures may now be of greater value. These measures can provide insight into areas of operational differences between competing spaceports and identify areas for improving the performance of spaceports. This paper suggests Figures of Merit (FOMs) for spaceport 'Capacity' (number of potential launch opportunities per year and / or potential mass' to low earth orbit (LEO) per year); 'Throughput' (actual mass to orbit per year compared to capacity); 'Productivity' (labor effort hours per unit mass to orbit); 'Energy Efficiency' (joules expended at spaceport per unit mass to orbit); 'Carbon Footprint' tons CO2 per unit mass to orbit. Additional FOMS are investigated with regards to those areas of special interest to commercial launch operators, such as 'Assignment Schedule' (days required for a binding assignment of a launch site from the spaceport); 'Approval Schedule' (days to complete a range safety assessment leading to an approval or disapproval of a launch vehicle); 'Affordability' (cost for a spaceport to assess a new launch vehicle); 'Launch Affordability' (fixed range costs per launch); 'Reconfigure Time' (hours to reconfigure the range from one vehicle's launch ready configuration to another vehicle's configuration); 'Turn,Around Time' (minimum range hours required between launches of an identical type launch vehicle). Available or notional data is analyzed for the KSC/CCAFS area and other spaceports. Observations regarding progress over the past few decades are made. Areas where improvement are needed or indicated are suggested.
