The W86 was an American earth-penetrating ("bunker buster") nuclear warhead, intended for use on the Pershing II intermediate-range ballistic missile (IRBM). The W86 design was canceled in September 1980 when the Pershing II missile mission shifted from destroying hardened targets to targeting soft targets at greater range. The W85 warhead, which had been developed in parallel with the W86, was used for all production Pershing II missiles.[1]

Development work for the W86's penetrator case began in 1975 at Sandia National Laboratories. The weapon was intended to allow for the destruction of hardened structures and the cratering of runways while using smaller yields.[2]
