The Pentagon notified Congress last week that it will be diverting critical anti-drone technology that had been allocated for Ukraine to US Air Force units in the Middle East, according to correspondence obtained by CNN and people familiar with the matter.

According to the Wall Street Journal, special fuzes used in ground-to-air rocket systems that protect against drone attacks will be redirected towards units in the Middle East, as the U.S. braces for conflict with Iran as well as Houthi militants in Yemen.

The US department of defence has informed Congress that it is diverting critical anti-drone technology originally earmarked for Ukraine by the Joe Biden administration to support US Air Force operations in the Middle East.
