Product Description
“One of my favorite ideas for a number of years[…]if a 2500-pound highly steamlined shape made of tool steel[…]were to be launched from altitude by an SR-71 it would hit sea level at speeds well above Mach 3. Such a bomb could go through 300 feet of earth. It could, for example, plug the tunnels through the Ural mountains. It could penetrate 33 feet of reinforced concrete.
We could expect the bomb to hit well within a thirty-foot target area when dropped from 85,000 feet.”
—from “Kelly: More Than My Share of It All”—Clarence L. “Kelly” Johnson, 1989

Speculative design for an air-dropped kinetic “energy bomb” weapon proposed by Lockheed in the 1960s for use in a bomber derivative of the SR-71. Although armed variants of the SR-71 would be proposed as late as the 1970s and early 1980s—aside from the related development of the YF-12 interceptor, which reached prototype stage—none were ever built.

This weapon is based off a low-drag Sears-Haack body with the approximate volume of the 2500 lb mass of hardened steel, as matched to fit within the dimensions of A-12/SR-71 weapon bays. With, according to my rough calculations, a coefficient of drag of roughly 0.052.

To put it plainer…it’s an unguided, supersonic, ton-and-a-half lawn dart that can be crammed onboard a Blackbird. For your bunker-busting or anti-shipping needs.
