US delays Japan’s Tomahawk missile supplies as Iran strikes take priority

Tomahawk missiles are a centrepiece of Tokyo’s new strategy of equipping itself with long-range strike capabilities to deal with challenges from China and North Korea.

But Washington has informed Tokyo that deliveries for its order for about 400 missiles by March 2028 would be disrupted, according to people familiar with the situation.

The US has launched hundreds of Tomahawk missiles during the attack on Iran, according to one person familiar with the matter, who did not want to be named because of the sensitivity of the issue.

There were about 4,000 Tomahawks in US stockpiles before the war, including older models and anti-ship variants.

Japanese Defence Minister Shinjiro Koizumi said in March that the first shipment of Tomahawks had been received.

It is unclear whether there is a risk the US would miss the overall March 2028 deadline to complete shipments because of expected disruptions to the flow of deliveries.

The Pentagon declined to comment, while Japan’s defence ministry did not respond to a request for comment.

RTX spokesman Chris Johnson said he was unaware of Japan being informed about shipment disruptions.

The setback comes after Tokyo recently announced that the destroyer Chokai had completed modifications in the US to make it the first Japanese warship able to fire the missiles, which have
