History of The Azores - 20th Century

20th Century

During the Second World War, in 1943, the Portuguese dictator Salazar leased bases in the Azores to the British. This represented a change in policy. Previously the Portuguese government only allowed German U-boats and navy ships to refuel there. This was a key turning point in the Battle of the Atlantic, allowing the Allies to provide aerial coverage in the middle of the Atlantic (i.e. it closed the Mid-Atlantic Gap). This helped them to hunt U-boats and protect convoys.

In 1944, American forces constructed a small and short-lived air base on the island of Santa Maria. In 1945, a new base was founded on the island of Terceira and is currently known as Lajes Field. It was founded in an area called Lajes, a broad, flat sea terrace that had been a farm. Lajes Field is a plateau rising out of the sea on the northeast corner of the island. This air force base is a joint American and Portuguese venture. Lajes Field has, and continues to support US and Portuguese military operations. During the Cold War, the US Navy P-3 Orion anti-submarine squadrons patrolled the North Atlantic for Soviet submarines and surface spy vessels. Since its inception, Lajes Field has been used for refuelling aircraft bound for Europe, and more recently, the Middle East. The US Army operates a small fleet of military ships in the harbor of Praia da Vitória, three kilometers southeast of Lajes Field. The airfield also has a small commercial terminal handling scheduled and chartered passenger flights from other islands in the archipelago, Europe, and North America.
