This Airbase was the largest underground military base and airport in all of the former Yugoslavia. The property is located on the current border of Bosnia and Croatia. The complex was built in 1948 - It was codenamed 505. The construction was completed 20 years later. The purpose of the facility was to establish, integrate and coordinate the nationwide early warning network of the Socialist Federated Republic of Yugoslavia, similar to NORAD (North American Air Defense Command). There were semicircular concrete shields, spaced ten meters apart to reduce the impact of the attack on the object. The complex had an underground water source, power generators, crew quarters and other strategic military facilities. Aircraft was used in 1991 during the Yugoslav War. Yugoslav People's Army During the withdrawal, it destroyed the runway by detonating explosive charges. In order to prevent any further use of the complex, Serbian troops detonated 56 tons of explosives. During exploration, a possible meeting of the police, the border guards of Croatia and the army should be reconsidered. The tunnels are buried, due to the underground connection with Bosnia, which would constitute a "wild" border crossing.

At a loose end this afternoon I met up with Landie Man and after some faff found ourselves in Newbury, I'd wanted to see the fire plane at the Greenham site for a long time so now was a good chance...a very interesting little piece of base history.
Oh, and it was bloody cold.
