Northrop Grumman leader warned that Western weapons storage was not prepared for prolonged conflicts in Ukraine.

It is important to have a clear signal of demand and the level of future arsenal mobilization.

The US and its allies in NATO have provided a large amount of weapons for Ukraine for more than 4 months of fighting with Russia.

The limitations in the global supply chain also caused defense corporations to struggle to search for essential components, making the waiting time two to three times.

Another US leading defense corporation also shared its view with the leader of Northrop Grumman.

Raytheon Group at the end of April warned that it would take many years to compensate for the US Stinger's shoulder -to -shoulder missile reserves after transferring large amounts to Ukraine.

Senator Mike Gallagher, member of the US House of Representatives Military Service, in May, said Washington's Javelin rocket reserves were running out.

Josep Borrell, officials in charge of foreign policy of the European Union (EU), also warned member countries can run out of weapons in the Ukrainian aid effort.

The warehouse of exhausted weapons after the military aid effort for Ukraine is the best example of our shortcomings.

The United States continuously transferred weapons to Ukraine because he wanted to maintain the fighting power for this country, while avoiding discrediting with allies.

EU officials warn members of the member countries may run out of weapons in the Ukrainian aid effort, calling for enhancement of military capacity in the bloc.
