The United States (US) has approved the sale of up to three Boeing P‑8A Poseidon maritime patrol aircraft to NATO ally Denmark, in a deal estimated to be worth $1.8 billion.
On December 29, 2025, the Defense Security Cooperation Agency said the State Department had “made a determination approving a possible foreign military sale” to Denmark.
The $1.8 billion price tag would include multi-mission maritime patrol and reconnaissance aircraft with indirect fire protection capability and related equipment.
According to the Defense Security Cooperation Agency, Denmark requested the purchase of up to three P‑8A Poseidon aircraft plus a wide range of military systems.
In a statement, the Defense Security Cooperation Agency claimed that the sale would “support the foreign policy goals and national security objectives of the United States by improving the security of a NATO Ally that is a force for political stability and economic progress in Europe”.
The agency added: “The proposed sale will enhance Denmark’s capability to meet current and future threats by providing a credible force that is capable of deterring adversaries and participating in NATO operations. The proposed sale will support its goal of improving national and territorial defense as well as interoperability with US and NATO forces.”
The implementation of the sale would require as many as 14 government and contractor representatives to travel to Denmark for a duration of up to two years.
There, they would support aircraft fielding and maintenance, mission systems, training, and logistics and engineering technical assistance.
The Boeing P-8 Poseidon is a multi-role maritime patrol aircraft, equipped with a naval search radar for search and tracking capability.
It can also be fitted, both internally and externally, with an array of armaments dedicated to submarine and anti-ship warfare, such as torpedoes, mines, depth charges and anti-ship missiles.
