A no-longer-secret submarine base can be yours for $17.3M

A so-called "secret" submarine base has been put on the market by the Royal Norwegian Navy. Like the rest of the world, real-estate devaluation has hit the base hard. Built for $494 million back in 1967, today's asking price of $17.3 million is a veritable fire sale. Built by NATO and shared with the Norwegian Navy and U.S. forces over the years, the sprawling lair includes a dry dock and a tunnel system burrowed into a mountain as well as 145,313 square feet of above-ground office space. Details about neighborhood safety, the nearby school system and any convenient submarine-accessible shopping options were not included in the ad.
