Despite concerns over the war in Iran, Estonia will still receive rockets for its US-made M142 HIMARS multiple launch rocket systems. However, these will only be 70-km-range munitions, while the United States is currently not supplying its allies with ATACMS missiles capable of reaching targets up to 300 km away.
Estonian Defense Minister Hanno Pevkur confirmed this, according to ERR. He said that Estonian specialists are currently preparing a batch of guided rockets, which will be shipped to Estonia once all the necessary procedures have been completed.

Defense Express notes that Estonia ordered HIMARS systems with ATACMS missiles back in 2022, but four years later it still may not receive the complete package. However, the capability to hold targets around St. Petersburg at risk may not remain a gap for long and could potentially be filled without US involvement.
In December 2025, Estonia ordered six South Korean K239 Chunmoo multiple launch rocket systems along with three types of missiles. These include the 239-mm CGR-080 with a range of 80 km, the 280-mm CTM-MR with a range of 160 km, and the 600-mm CTM-290 with a range of 290 km. Deliveries are expected to begin in early 2027.
This means that the Estonian military could receive a South Korean alternative to ATACMS in roughly a year. However, there is no precise information on when the long-range CTM-290 missiles will actually be delivered, so the timeline could extend beyond that.
The situation also highlights the rationale behind Estonia’s decision to acquire K239 Chunmoo systems in addition to HIMARS. This gives the country an alternative source of long-range rocket ammunition rather than leaving it dependent on a single supplier. Estonia is also continuing to order M142 HIMARS systems and purchased three additional US launchers in spring 2026.
Unless the United States changes its position sooner, however, Estonia will not have the ATACMS ballistic missiles it ordered back in 2022 for at least the next year. In the event of a war, this would leave a gap in Estonia’s ability to strike targets at ranges of up to 300 km.
The United States has reportedly used up almost all of its ATACMS and PrSM stocks during the war with Iran. Replenishing these inventories may not be quick, meaning it remains unclear when deliveries to allies could resume.
Croatia, meanwhile, has also cited the suspension of ATACMS deliveries as one of the reasons for acquiring K239 Chunmoo systems. At the same time, Croatia has not abandoned its plans to acquire HIMARS, meaning it too is pursuing a degree of diversification in its sources of rocket ammunition.
