Multiple outlets report that Russia is secretly assisting Iran’s development of supersonic cruise missiles, citing leaked information about a programme involving technology transfer from Moscow to Tehran. The reports characterize the effort as among the most significant known transfers of military capabilities between the two countries.

The coverage is based on leaked or investigative material rather than publicly confirmed details from the governments involved. Financial Times describes the work as a programme behind a major military-technology transfer, while the Daily Mail similarly frames it as secret assistance toward supersonic missile capability. The outlets differ mainly in phrasing and emphasis, but they largely align on the core claim: that Russian support is part of Iran’s efforts to develop supersonic missiles, specifically cruise missiles.

None of the provided summaries includes specific technical specifications, production timelines, or definitive evidence that has been independently verified within the text, nor do they cite direct statements from Russian or Iranian officials. The reports therefore present an allegation of covert involvement grounded in leaked information.
