Biden secretly approved the transfer of the long-range ATACMS missiles in February for use inside Ukrainian territory.
The Biden administration had resisted sending the long-range missiles in part because of readiness concerns.
Lockheed Martin, which manufactures the ATACMS missiles, is in full-rate production and produces approximately 500 missiles per year, a spokesman for the company said in September.
The US worked behind the scenes to address the readiness concerns, which included buying more ATACMS missiles and filling US military stocks.
Ukrainian officials have been asking the US in private and in public for the long-range missiles to target deeper behind Russian lines.
