It was a cruise missile with an unshielded nuclear reactor for an engine, and it was meant to fly for weeks.<\/p>\n<p>The engine program was called Project Pluto. The missile was SLAM, the Supersonic Low Altitude Missile. Its own director nicknamed it the flying crowbar.<\/p>\n<p>It never flew a single mission.

Normally you heat that air by burning fuel. Project Pluto's engineers had a darker idea. They would heat it with a nuclear reactor.<\/p>\n<p>Strip out the fuel tanks and a nuclear-powered aircraft can fly almost forever. That was the whole point. SLAM could loiter for weeks, then dash toward its targets at three times the speed of sound, so low that no 1960s radar or interceptor could touch it.<\/p>\n\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img data-opt-id=1986126665  fetchpriority=\"high\" decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/ml5psubhxdln.i.optimole.com\/cb:EQu6.cc73\/w:auto\/h:auto\/q:mauto\/ig:avif\/https:\/\/migflug.com\/jetflights\/wp-content\/uploads\/sites\/4\/2026\/08\/project-pluto-slam-nuclear-ramjet-doomsday-missile-b0-1.jpg\" alt=\"A Project Pluto reactor test\" style=\"width:100%;height:auto;max-width:100%;display:block;border-radius:6px\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">The Tory nuclear ramjet reactors were tested in the Nevada desert, mounted on railcars because nobody dared let one fly.

SLAM would race across enemy territory at rooftop height, dropping hydrogen bombs one after another along a winding route, hitting city after city on a single mission.<\/p>\n<p>Its blunt, purposeful shape earned it a grim nickname from the project's own director, and the name stuck because it was accurate: this was not an elegant weapon, it was a club.<\/p>\n\n<div style=\"background:#f8f9fa;border-left:4px solid #d32f2f;padding:20px 22px;margin:18px 0 24px;border-radius:0 8px 8px 0;font-size:16px;line-height:1.7;display:flex;gap:20px;align-items:flex-start\"><div><em>&ldquo;the flying crowbar.&rdquo;<\/em><div style=\"margin-top:10px;font-size:14px;color:#555\"><strong>Ted Merkle<\/strong> &mdash; Project Pluto director, on the SLAM missile<\/div><\/div><\/div>\n<h2 style=\"padding-top:22px\">A weapon that killed just by passing<\/h2>\n<p>Here is the part that horrified even its creators. The reactor at the heart of SLAM had no shielding to save weight, so the missile left a trail of radioactive exhaust everywhere it flew. Its passage at low level produced a shockwave and a noise so violent that it could injure people on the ground.<\/p>\n<p>In other words, SLAM could kill you without dropping a thing. Just having it scream overhead, spewing fallout and a deafening boom, was a weapon in itself. That made it almost impossible to test, because where do you fly a machine that poisons everything beneath it?<\/p>\n\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/qQGBBsLiP6w\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;border-radius:8px\" allowfullscreen><\/iframe><\/div>\n<h2 style=\"padding-top:22px\">Tory roars in the desert<\/h2>\n<p>The reactor itself was real, and it worked. Engineers built test units called Tory-IIA and Tory-IIC and ran them at a remote site in the Nevada desert, bolting them to railcars because letting one fly was unthinkable.<\/p>\n<p>In 1964, Tory-IIC roared to full power for a few minutes, proving that a nuclear ramjet could actually breathe fire. It was a genuine engineering triumph, attached to a genuinely monstrous idea.<\/p>\n\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/CXoRg4CJ6kU\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;border-radius:8px\" allowfullscreen><\/iframe><\/div>\n<h2 style=\"padding-top:22px\">Too terrible to deploy<\/h2>\n<p>By mid-1964 the ground had shifted. Intercontinental ballistic missiles had arrived, delivering warheads faster and more cheaply than any low-flying nuclear cruise missile ever could. And SLAM raised a queasy question its planners could not answer: a weapon this provocative, this uncontrollable in testing, might be more dangerous to its owners than to the enemy.<\/p>\n<p>In July 1964 Project Pluto was cancelled. The flying crowbar never left the ground, and more than a few of the people who built it were quietly glad. Some weapons, it turns out, are so effective that even a superpower flinches.<\/p>\n\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/J-8Jarqv7hY\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;border-radius:8px\" allowfullscreen><\/iframe><\/div>\n\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img data-opt-id=1026504334  fetchpriority=\"high\" decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/ml5psubhxdln.i.optimole.com\/cb:EQu6.cc73\/w:auto\/h:auto\/q:mauto\/ig:avif\/https:\/\/migflug.com\/jetflights\/wp-content\/uploads\/sites\/4\/2026\/08\/project-pluto-slam-nuclear-ramjet-doomsday-missile-b1-1.png\" alt=\"The Nevada Test Site\" style=\"width:100%;height:auto;max-width:100%;display:block;border-radius:6px\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">Jackass Flats, Nevada, where the reactor roared to life at full power for the first and last time.
