The disclosure comes after we revealed 50,000 animals were killed at the Wiltshire base
between 2010 and 2017.
Other research carried out for the US by British experts included animals exposed to Mustard and Phosgene gas.
All the experiments were carried out at the Defence Science and Technology Laboratory.
In one experiment, 12 marmoset monkeys were infected with the Ebola virus under a Pentagon-funded project. The project was part of a £3million US-funded programme which ran from 2012 to 2016.
All infected marmoset monkeys died from six to 10 days after exposure to the Ebola virus.
Jessamy Korotoga, campaign manager at Animal Aid, said: “Warfare experiments on animals are morally reprehensible, leading to the most profound suffering, pain and distress.
“If animal experiments are being conducted here, which are illegal elsewhere, this is outsourcing of the most ethically corrupt and heinous kind. It also puts paid to the argument, we so often hear, that laboratory animal welfare in Great Britain is the best in the world.”
PETA founder Ingrid Newkirk recently criticised the Ministry of Defence for conducting animal experiments.
She said: “When we have access to computer models, human tissues and other modern research methods, it’s unfathomable that the Ministry of Defence is still torturing and killing animals.”
A spokesperson for The Defence Science and Technology Laboratory said: “Dstl sometimes undertakes research on behalf of close allies. We do not carry out research on animals that would be prohibited in the US.”
