War reserve stock

[2] The United States' Department of Defense[3] maintains war reserve stocks around the world, mainly in NATO countries and in some major non-NATO allies.

[citation needed] But smaller wars of shorter duration where belligerents have already stockpiled sufficiently for the outbreak of conflict are able to rely on pre-existing stock.

[13] With the agreement of the Israeli government, the United States transferred large numbers of 155 mm artillery rounds from WRSA-I stocks to Ukraine following the Russian invasion of the country in 2022.

Within their war reserves, Israel keeps ammunition, spare parts and replacement equipment needed for at least a month of intense combat.

[18] The United Kingdom maintains a war reserve stock that has been criticized by the National Audit Office as being unnecessary.

The NAO reported in June 2012 that the annual cost of maintaining the nation's entire war reserve stockpile was £277 million.
