This paper describes four hardened basing concepts for B-52 bombers and summarizes existing data and analyses of their technical feasibility, survivability, and costs. The concepts are (1) "conventional" hardened hangers, (2) "Cliff Dweller," a superhard design that places aircraft inside mountain tunnels, (3) "Mountain Side," a design that includes parts of the conventional and Cliff Dweller systems, and (4) "Hardcore," a design that recovers aircraft at hardened support facilities rather than a system of hardened storage of aircraft.
