According to the DSCA, Estonia is seeking to purchase six additional M142 HIMARS systems along with a substantial quantity of missiles and related support. The proposed package includes 856 launch pod containers with various types of Guided Multiple Launch Rocket System (GMLRS) munitions—M30A2 with alternative warheads, M31A2 with unitary warheads, and extended-range XM403 and XM404 variants—as well as 5,136 total rockets including 227mm calibre rounds.
The request also covers 182 MGM-140 M57 ATACMS ballistic missiles, a notably high number for a country of Estonia’s size. Additionally, the deal would include support equipment, logistics, and training services as part of the Foreign Military Sales programme.
The total value of the potential package is estimated at up to $4.23 billion. If the US Congress approves the request—or takes no action within 30 days—Estonia will be able to begin negotiations on the final Letter of Offer and Acceptance (LOA).
Given current defence budget projections, it is unlikely Estonia would acquire the entire package under a single agreement. According to the country’s draft budget, Estonia’s defence spending is expected to slightly exceed $2.8 billion in 2026.
Estonia already operates HIMARS systems, having ordered six launchers in December 2022 along with munitions and a logistics and training package worth over €200 million. The majority of that deal—$140.5 million—was financed through US military aid.
Delivery of the systems was completed in April this year, and in July, Estonia conducted its first live-fire exercises with the HIMARS on the island of Saaremaa. If the new request goes ahead, Estonia will double its HIMARS fleet and significantly expand its GMLRS and ATACMS missile stockpile.
