Departing from RAF Brize Norton in Oxfordshire, an A400M aircraft delivered the vaccines on behalf of the Foreign, Commonwealth & Development Office to MOD Gibraltar.
Six cold cases of Pfizer-BioNTech vaccines were also delivered to RAF Gibraltar in January, enough for almost 6,000 jabs.
As of 17 May, Gibraltar, with a population of about 34,000, has seen 94 deaths due to COVID-19, with 4,283 residents infected with the virus.
'Operation Freedom', which began in January, has seen Gibraltar vaccinate the bulk of its adult population, and the programme's success has meant masks are no longer compulsory, except in shops and on public transport, and as of 4 May the territory had not had a new local case of the virus in six weeks.
Gibraltar is one of the few destinations on the UK's green list, allowing quarantine-free travel since Monday.
