Which country recently launched the “Inmarsat-6 F1 satellite”?

Inmarsat-6 F1 is a communications satellite developed and built by Airbus Defence and Space on the Eurostar 3000EOR satellite bus for the British satellite operator Inmarsat. It will be Inmarsat's first dual-payload spacecraft, with operations in both L-band and Ka-band, and will be part of the Inmarsat-6 satellite fleet. As the first of two such spacecraft, it was put into super synchronous transfer orbit on 22 December 2021, claiming to be the largest and most advanced corporate telecommunications satellite ever launched. The satellite will next be raised into the ultimate geosynchronous orbit by the inbuilt Fakel SPT-140D electric powertrain.
