Ariane 6 debuts P160C boosters on VA269, lofting 36 Amazon Leo satellites in a record
Arianespace · ArianeGroup · ESA · Amazon
ESA says the upgraded boosters made this the heaviest payload ever launched by a European rocket, beating Ariane 5's ATV.
what happened
Ariane 6 flight VA269 lifted off from Europe's Spaceport in French Guiana on June 17 at 09:21 local time, placing 36 Amazon Leo satellites into low Earth orbit at about 465 kilometers in a mission lasting 1 hour 51 minutes, per Arianespace and ESA. The flight debuted four boosters based on the P160C solid motor, each holding 14 tonnes more propellant than the P120C and raising performance 10 to 15 percent depending on orbit; ESA says the launch set a record for the most cargo taken to space by a European launcher, surpassing Ariane 5's 20-tonne ATV Albert Einstein mission of 2013. Per Arianespace it was the eighth Ariane 6 launch, the third for Amazon Leo, and brought its Amazon Leo total to 100 satellites in under five months.
why it matters
The P160C is the upgrade that lets Ariane 64 carry four more Leo satellites per flight, which matters directly to Amazon's waiver-pressured deployment math and to Arianespace's economics on its 18-launch Leo series. Europe's heavy-lift record changing hands from ATV to a commercial megaconstellation stack is the industry shift in one image.
