A foreign country is helping to finance the modernisation of the South Uist rocket range.
Isles MP Angus MacNeil asked the government about investment in the site.
Philip Dunne, Minister for Defence Support replied: “International funding to broaden the capability of the Ministry of Defence (MOD) Hebrides Range has been agreed.”
Mr Dunne refused to give further information.
He added: “I am withholding further details as disclosure would or would be likely to prejudice relations between the UK and another state.
The Conservative MP highlighted that separate work to upgrade the air defence radar at Clettraval in North Uist is being funded entirely by the MOD with no investment from any other nation.
Four NATO countries have used assets at the Hebrides Range in the past 10 years: UK, Denmark, Germany and Belgium.
