There are 60 operational orbital launch vehicle types on a global basis. This article characterizes those launch vehicles in the following areas:
- Launch vehicle types by country
- Responsive launch
- Flight heritage
- Payload mass to LEO
Launch Vehicle Types by Country
China has the largest number, accounting for 38.3% of global operational orbital launch vehicle types.
96.7% of launch vehicles do not support responsive launch. The only responsive launch vehicles currently operational are the SSLV and Electron.
Responsive launch is characterized by the ability to launch a payload on short notice. Interest in responsive launch is primarily driven by national defense agencies. If a critical satellite is disabled, either due to technical reasons or due to an opponent’s counter-space activities, it provides a quick way to react to restore the mission. A responsive launch capability requires: orbital launch vehicles to be kept in stock and ready to deploy; fast payload integration; and on demand access to launch facilities.
96.7% of global launch vehicles are expendable. The only partially reusable launch vehicles are Falcon 9 and Falcon Heavy. Note that Falcon 9 and Falcon Heavy can both be used in expendable mode to deliver larger payloads into orbit.
The Long March 2C launch vehicle has the longest flight heritage with its first flight occurring in 1982.
Payload Mass to LEO
Medium-lift launch vehicles are the majority, representing over 46% of vehicles.
Launch vehicles are categorized by NASA according to Low Earth Orbit (LEO) payload capability:
|Launch Vehicle Categorization||Playload Mass to LEO|
|Small-lift launch vehicle||< 2000 kg|
|Medium-lift launch vehicle||2000 to 20,000 kg|
|Heavy-lift launch vehicle||> 20,000 to 50,000 kg|
|Super-heavy lift launch vehicle||> 50,000 kg|
Across all launch vehicle types, the payload mass to LEO ranges from a low of 4 kg to a high of 63,800 kg.
