Arianespace

Arianespace and the European Space Agency (ESA) say that their plans for the debut flight of the Ariane 6 launch rocket have been delayed into 2021, due to the Covid-19 pandemic that slowed or halted work on development projects related to the rocket.
Ariane 6 is the long-awaited replacement for the reliable Ariane 5 rocket and planned to be a valid financial competitor to SpaceX.
