“The conflict in Ukraine showed that our military-industrial base did not meet the required level for the production of ammunition,” RIA Novosti quoted him as saying.

Kahl added that now for Washington, increasing the volume of output has become a priority.

NATO Secretary General Jens Stoltenberg was previously forced to admit that the supply of ammunition to Ukraine "is not sustainable", since their "consumption is much higher" than the production rate in the alliance member states.

The bloc's Secretary General also stated that NATO's stocks of shells for deliveries to Kyiv have been depleted.
