More than 900 people have donated money to help clean up the Bomber Command Memorial after it was splashed with white paint.
The memorial commemorates more than 55,500 service members killed in World War Two.
So far the RAF Benevolent Fund has said that it has been "overwhelmed" by the support from across the world and donations have reached over £20,000.
Members of Bomber Command came from across the Commonwealth, from the UK, Canada, Australia, New Zealand, as well as occupied nations including Poland, France and Czechoslovakia.
Almost three-quarters of the 125,000 aircrew who served were killed, seriously injured or taken as prisoners of war.
Phase one of the clean up has been completed, which saw the white paint being removed from the statues and the memorial has been reopened to the public.
Phase two will be carried out over the next couple of weeks which will see the cleaning of the remaining paint and the bronze statue being resealed.
The police believe that the Bomber Command was the first of five memorials targeted by vandals last Sunday and Monday.
The other memorials which were attacked were the Canada Memorial in Green Park, the Royal Marines Graspan Memorial on The Mall, a memorial to murdered police officer Yvonne Fletcher and the "Allies Statue" of Second World War Prime Minister Sir Winston Churchill and his US counterpart Franklin D Roosevelt in New Bond Street.
The police have released images of a person wearing a face mask and ski goggles who they would like to talk to in connection with the attacks, and various rewards have been offered for information leading to a conviction.
