Exclusively for your blog :-) Although I might miss a few of your updates.

Please come with feedback for improvements! I’ll add number of first stages reused and pro forma tonnage for that. Since it is different for reused and expended F9s and I will gladly make reasonable adjustments from the simple Wikipedia numbers for LEO capacity that I start out with now.

LocalFluff: Thank you for this additional parameter. If you can add it to each of my launch race posts both I and my readers will be very grateful.

I’ll note capacity due to launcher failures too (with a minus instead of a plus sign, not affecting national total launch success).

As according to Wikipedia max capacity to LEO per rocket type (however LEO is defined, could be a short lived 200 km altitude, less than half the altitude of the ISS that needs yearly boosting to survive atmospheric drag). This simple method at least compares how much they COULD HAVE put in LEO (however it is defined, at lest one could adjust these numbers afterwards if someone knows a fair way to do that) And I of course use metric units, no body parts whether short nor long.

Until and including February 15th 2021:

WORLD 134,440 kg
USA 92,000 kg 68%
CHINA 27,200 kg 20%
RUSSIA 15,220 kg 11%

USA 92,000 kg
SpaceX (91,200 kg)
+ 4 of Falcon 9 Block 5 = 22,800 kg each
Rocket Lab (300 kg)
+ 1 of Electron = 300 kg each
Virgin Galactic (500 kg)
+ 1 LauncherOne = 500 kg as to SSO230km each

CHINA 27,200 kg
+ 2 of Long March 3B/E = 11,500 kg each
+ 1 of Long March 4C = 4,200 kg each
– 1 Hyperbola 1 = 300 kg LAUNCH FAILURE

RUSSIA 15,220 kg
+ 1 of Soyuz 2.1a = 7,020 kg each
+ 1 of Soyuz 2.1b = 8,200 kg each
