VILNIUS/TALLINN, April 17 (Reuters) - The United States

has informed Lithuania and Estonia of possible delays in the

delivery of U.S. military equipment because of the Iran war, the

Baltic countries' defence ministries told Reuters on Friday.

U.S. officials have informed some European counterparts,

including in the Baltics and Scandinavia, that some previously

contracted weapons deliveries are likely to be delayed as the

conflict draws on weapons stocks, Reuters reported on Thursday,

citing sources familiar with the matter. Washington did not

immediately comment.

Lithuania, Latvia and Estonia, which are all NATO members

bordering Russian territory, are devoting about 5% of their

gross domestic product to defence this year to urgently upgrade

their armed forces.

"Lithuania has been informed by Pentagon representatives

about possible delays in the delivery of ammunition purchased

from the U.S. due to the conflict," a Lithuanian defence

ministry spokesperson said in an email on Friday.

An Estonian defence ministry spokesperson said on Friday: "I

can confirm that we were informed about possible delays."

Neither ministry specified which contracted deliveries were

affected. Lithuania has about $640 million orders from the

United States, including Javelin anti-tank missiles, according

to the U.S. Department of State.

Estonia is in talks with the U.S. on "how to address these

supply challenges", Prime Minister Kristen Michal told a press

conference in Tallinn on Friday.

"Yes, the U.S. has informed us of the situation, and we

understand the reasoning and the circumstances", he said, adding

that the U.S. remained "our biggest ally".

Estonia's outstanding $160 million U.S. military orders

include the HIMARS rocket system and Javelin missiles.

Latvia has not been officially informed by the U.S. of

delivery delays, Latvian Prime Minister Evika Silina told the

same press conference.

"We are all cautious but for now all agreements are on

schedule", she said.
