The first concrete runway was built in 1943 between Eichistrasse and Lake Alpnach. It had a length of 875 meters (2,871 ft). Furthermore, eight type U-43 aircraft shelters and bunkers for command and ammunition were built. 
As part of the Swiss Reduitstrategie in 1952, aircraft caverns were built into the rock of the adjacent Mueterschwanderberg Mountain. The former Mueterschwanderberg artillery fortress was also built into the mountain, but on the Nidwalden. In 1960, the cavern facility was officially handed over to the Directorate of Military airfields. Beginning in 1958, de Havilland DH-112 Venom jets operated from Alpnach. In 1973, they changed to the Hawker Hunter and in 1979 there was a further change to the F-5 "Tiger". Because of the Army XXI reforms, flight operations from the caverns were terminated. On 20 January 1964, the Army helicopter base opened at Alpnach. 

Today, Alpnach Air Base is the main logistical base of the helicopters of the Swiss Air Force. Standard helicopter types used at Air Base Alpnach are the Aérospatiale Super Puma, Eurocopter AS532UL Cougar Mk1 and Eurocopter EC 635.
