Two more Russian hypersonic scientists are convicted of treason

The closed trial followed allegations tied to a gas-dynamics article published in a foreign journal, Russian media reported.

  • On Tuesday, The Novosibirsk Regional Court sentenced hypersonic technology researchers Valery Zvegintsev and Vladislav Galkin to 12.5 years in prison each on treason charges, Russian business daily Kommersant reported.
  • State-Run news agency TASS reported the case stemmed from a co-authored gas dynamics article published in an Iranian journal, though official details of the treason allegations remain undisclosed.
  • These sentences represent the latest in a broader Russian crackdown on the scientific community, following the imprisonment of former ITPM director Alexander Shiplyuk and chief researcher Anatoly Maslov.
  • Shiplyuk received a 15-year sentence in September 2024, while Maslov was handed 14 years in prison, both on similar treason charges related to hypersonic research work.
  • Zvegintsev and Galkin will remain under house arrest until the sentence takes effect; the researcher maintained his innocence by claiming the information in question was publicly available.
