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.
