Scalar weapons and UFO shootdowns
Scalar weapons and UFO shootdowns refers to the claimed history of US military and other governments attempting to bring down non-human aerial vehicles using radar, directed-energy beams, and related electromagnetic technologies, with the 1947 Roswell crash cited as a possible early instance and additional recoveries alleged in later decades.
The Roswell crash and radar interference
Philip Corso, who held the Army's Roswell file at the Pentagon Foreign Technology desk from 1961, recorded Army scientists' assessment that the Roswell vehicle was brought down by a combination of the severe electrical storm over New Mexico on the night of July 4–5, 1947, and the persistent tracking radars operating from the 509th Bomb Wing at Roswell Army Air Field and from the missile and nuclear testing facilities at Alamogordo: "the object that was either caused by lightning or by our targeting radar, some say, and fell out of the sky that night." Army R&D scientists specifically theorized that the craft's electromagnetic propulsion system — which navigated by manipulating an electromagnetic field — was disrupted by radar lock-on signals emanating from the 509th or Alamogordo, causing the vehicle's guidance to fail.
Lue Elizondo, drawing on information from Hal Puthoff and other sources within the AATIP program, wrote that the UAP that crashed at Roswell "had been conducting some sort of reconnaissance on our budding atomic program when the unexpected happened. An electromagnetic pulse generated from one of the nearby test ranges had inadvertently intervened with the craft's technology and caused it to crash." Puthoff's specific theory, as relayed by Elizondo, was that if EMP from DoD nuclear testing experiments had accidentally downed the Roswell craft, this implied the vehicle had "an Achilles' heel" — a vulnerability to directed energy sources analogous to conventional electronics: "If the Roswell aircraft were downed with an EMP by accident, this could mean the aircraft had an Achilles' heel. It might mean that their tech then functioned in many ways similar to modern aircraft and motor vehicles in that they may have some sort of circuitry or vulnerability to directed energy sources."
The radar-interference hypothesis also appeared in a declassified FBI memorandum dated March 22, 1950, from Special Agent in Charge Guy Hottel in Washington, D.C. to FBI Director J. Edgar Hoover, which stated that three flying saucers "were found in New Mexico due to the fact that the Government has a very high-powered radar set-up in that area and it is believed the radar interferes with the controlling mechanism of the saucers." The Hottel memo — one of the most-viewed documents in the FBI's online reading room — represented an early official acknowledgment, however secondhand, that electromagnetic interference was understood as a possible cause of UFO crashes as early as 1950.
The proximity of the crash to the Trinity site — the location of the July 1945 first nuclear detonation at the White Sands Missile Range — was noted by several researchers as potentially significant: the area around Alamogordo and White Sands represented the densest concentration of high-power radar and electromagnetic testing equipment in the United States at that time, making the Roswell area a zone of unusually intense electromagnetic activity that may have been hostile to an electromagnetically-propelled vehicle.
Corso's electromagnetic pillars account
In private interviews with journalist Paola Harris, Corso offered an account of the Roswell crash mechanism that went beyond standard radar interference. Harris recorded Corso describing "electromagnetic pillars" — rotating columns of electromagnetic energy generated by the intense electrical storm over New Mexico — that functioned as a dimensional gateway: "The night when this crash happened, Mac Brazel said there was a bolt of lightning hit. Wilbur Smith, the Canadian physicist told me about the electrically charged electromagnetic pillars. If a plane or a ship is in water, and there is a lighting hit, the nuclear binding comes apart. When one of these electromagnetic pillars is moving and something hits it, it can cause wildfires, they can become invisible." Corso told Harris that in 1947, two craft collided with "two whirling electromagnetic pillars that held a storm-induced gateway between them," and that one UFO crashed while one "showed up ten years later near Red Canyon, N.M."
According to Harris, Corso understood radar as a deliberate factor in UFO crashes: "On later occasions, the Colonel told me that they received orders to shut their radars off during the day. He knew that radar interfered with the navigation systems of these crafts. Obviously, he had not always done that and we know there were several UFO crashes in New Mexico." In a personal encounter Corso described to Harris at Red Canyon, a non-human being directly requested that Corso shut down his radars so it could depart, implying the craft could not fly while the radar field was active: "He wanted me to shut down my radars so he could leave."
Radar lock-on as a weapon
According to Corso, established the mechanism by which radar could inadvertently — or deliberately — damage or down a craft using electromagnetic propulsion: targeting radar signals, designed to guide missiles to aerial targets, "somehow interfered with their navigational ability and the vehicle's flight became erratic. If we were especially fortunate and able to boost the signal before they broke away, we could actually bring them down." This implied a passive effect of standard military radar, not a purpose-built scalar weapon.
Corso observed this behavior directly during his posting to West Germany with an anti-aircraft missile battalion in the late 1950s, where unidentified craft would approach US installations and then react to targeting radar engagement by becoming unstable: "Whenever we'd get just about there for an aerial sighting, they'd take off out of the atmosphere at speeds over 7,500 miles an hour."
Ramstein 1974
Corso documented a claimed successful missile shootdown near Ramstein Air Force Base in Germany in May 1974: "an army air defense battalion did with an antiaircraft missile near Ramstein Air Force Base in Germany in May 1974. The spacecraft managed to crash land in a valley. The craft was retrieved and flown back to Nellis Air Force Base in Nevada." This represents the most specific claimed instance of a deliberate US military shootdown of a non-human vehicle.
Directed-energy development
The vulnerability of electromagnetically-propelled craft to targeted energy beams was recognized from the earliest analysis of the Roswell vehicle: since lightning — itself a "directed energy beam of one of the highest magnitudes" — may have contributed to the 1947 crash, Army scientists concluded that artificially generated electron beams would have analogous effects: "if the craft had been brought down by lightning, itself a directed energy beam of one of the highest magnitudes, then it revealed their vulnerability to bolts of electrons. That stimulated the thinking of army scientists and researchers into the analysis of the potential of a directed energy beam weapon."
The Advanced Research Projects Agency (ARPA) began experiments with a particle beam accelerator designated "Seesaw" in 1958, designed to fire intense beams of electrons or neutral hydrogen atoms at incoming targets. Corso cited the Roswell analysis as a direct driver of this program and of subsequent laser development, writing to General Arthur Trudeau in 1962 that directed energy weapons offered military benefits including the potential to track and shoot down UFOs: "We saw the lasers too as our best weapon for not only tracking UFOs from the ground, from aircraft, or from satellites but, if we could boost the power to the necessary levels, for shooting them down."
Bluegill Triple Prime and Operation Dominic
Harald Malmgren, a presidential advisor who served as a cost analyst for the Operation Dominic nuclear test series in 1962, described the Bluegill Triple Prime test — an X-ray-based missile defense detonation conducted in October 1962 at Johnston Atoll during the Cuban Missile Crisis — as having also functioned as a UFO shootdown. Malmgren reported that during the test, a "tag-along" unidentified object was monitoring the nuclear detonation and was knocked down by the X-ray-induced electromagnetic pulse: "the report said this appeared to knock down this device they call it. I said the tag-along." The Navy recovered the downed object, but Malmgren was denied further access: "Tell me about it. Oh, we can't do that. You need to know about the incoming missile and the test but not about the tag-along."
Malmgren confirmed to his daughter Pippa and co-author Jeffrey Cruikshank — as well as to Senate Intelligence staffer Kirk McConnell — that "the entire Bluegill shoot down was an attempt to down a UFO" and that "we downed a UFO that was monitoring, closely monitoring that test and it tumbled into the ocean and that the Navy picked it up." The underlying mechanism was EMP disruption of the craft's navigation: EMP disrupts local magnetic fields, and craft using quantum sensing of the Earth's magnetosphere for navigation would lose stability when that field was locally perturbed.
Roswell survivor and the directed-energy concept
Malmgren relayed on his deathbed that the CIA and Atomic Energy Commission obtained the concept for directed-energy UFO shootdowns from a non-human being that survived the 1947 Roswell crash: "the CIA and Atomic Energy Commission got the very idea of shooting down UFOs with directed energy from an extraterrestrial being that survived the Roswell crash in 1947." Richard Bissell, then deputy director of plans for the CIA, subsequently briefed Malmgren on otherworldly technologies and confirmed the connection between the nuclear testing program and the UFO phenomenon. Per Malmgren, the trajectory from the surviving being's information to the Bluegill tests to the Strategic Defense Initiative represented a continuous line of development: the US military learned it could "bait UFO with nukes and destabilize their flight paths with EMP" and progressively refined this capability over three decades.
SDI and the space-based defense layer
The Strategic Defense Initiative (SDI), announced by President Reagan in 1983, is described by Corso as having a dual mandate: defense against Soviet ballistic missiles and — as the primary classified rationale — achievement of the capability to "disable enemy spacecraft," drawing on alien technology recovered from Roswell (lasers, accelerated particle-beam weapons, and stealth aircraft features) as its core toolkit: "in the end we were able to deploy enough of the Strategic Defense Initiative, 'Star Wars,' to achieve the capability of knocking down enemy satellites, killing the electronic guidance systems of incoming enemy warheads, and disabling enemy spacecraft, if we had to, to pose a threat."
Corso described the Army space station proposals of the early 1960s as explicitly targeting extraterrestrial craft: "The space station would, according to the army plan, effectively provide the platform for testing Earth to space weapons, and these, General Trudeau and I agreed, would be primarily directed against the hostile extraterrestrials who were the real threat to our planet."
Steven Greer, founder of the Disclosure Project, has argued that the current generation of anti-UAP weapons has advanced well beyond radar interference into genuinely exotic scalar technology. In a 2024 interview, Greer described classified weapons systems that use recovered extraterrestrial electronics as their functional basis — "hundreds of thousands of years more advanced than what the normal person knows about" — and identified them as having already been weaponized and used against ET craft: "Those weapon systems are targeting ET craft and other places out in space. They're going beyond the speed of light. These are quantum potential weapons that are scalar, that go way beyond the speed of light and are very dangerous. And these are under the control of" a covert private group operating outside governmental oversight. Greer's claim represents a significant escalation of the Corso framework: where Corso described targeting radar inadvertently and then deliberately disrupting electromagnetic propulsion, Greer describes intentional weapons capable of engaging craft at superluminal velocities — implying the scalar weapon itself operates via tachyon or quantum potential effects rather than any conventional electromagnetic mechanism. Per Greer, the weapons technology was derived from exactly the recovered extraterrestrial systems it is now used against.
Pattern of crashes near nuclear zones
Researchers including Michael Salla have noted a recurring pattern of non-human vehicle events concentrated around US nuclear and electromagnetic testing facilities: the July 1947 Roswell crash occurred directly adjacent to White Sands, the 509th nuclear bomber wing, and the Alamogordo nuclear test range; and the three major sites where US government facilities hold recovered craft — Norton Air Force Base, Edwards Air Force Base, and Nellis — are all located in the same southwestern electromagnetic testing corridor. According to Corso, suggests the military concluded that nuclear test zones and concentrated radar fields posed an inherent navigational hazard to electromagnetically-propelled vehicles, and that this made such zones natural sites for both crashes and for the development of anti-vehicle capabilities.
Government insiders interviewed by Linda Moulton Howe corroborated this pattern, stating that "microwave radar experiments conducted at White Sands Missile Range in the 1940s might have interfered with the extraterrestrial craft guidance systems."Cite error: Closing </ref> missing for <ref> tag This marks the first time a self-identified program insider corroborated the radar-crash theory on a mainstream public platform, independent of both Corso's published account and Greer's Disclosure Project witnesses.
Electromagnetic vulnerability — the engineering perspective
Defense engineer Dave Rossi, who works on advanced propulsion experiments, offered an independent engineering analysis of radar interference with UAP craft consistent with Corso's observations. According to Rossi, ordinary military tracking radar could destabilize the propulsion of electromagnetically-propelled craft, describing the interaction as "a form of understanding science more than technology" — an insight into the fundamental physics of how electromagnetic navigation systems respond to external field disruption rather than a purpose-built weapon. He attributed the vulnerability to the same physics underlying all field-based propulsion: craft that navigate by manipulating a local space-time metric are susceptible to any external electromagnetic signal that perturbs that metric.
Pais and Rossi describe field-based propulsion systems as operate by curving local space-time — "not viewing things as a straight line but rather as a curve" — and that any external electromagnetic interference capable of disrupting this curvature would effectively disable the craft's navigation: "a lot of these effects that we're seeing whether it's out of the MH-370 video or whether it's out of, you know, a UAP or, you know, even paranormal experiences — a lot of this has to do with the notion of curving space-time." This provides an engineering-level explanation for the pattern Corso described: radar signals used for targeting do not damage craft through kinetic or thermal mechanisms but by introducing coherent electromagnetic energy into the field environment the craft's propulsion system depends on — analogous, as host Ashton Forbes noted, to a sonic attack disrupting Venom's symbiosis in comic book fiction, or kryptonite against Superman: not a direct weapon but a field incompatibility.
Radiant Technology and Prompt Global Strike
Attorney Danny Sheehan identified a classified weapons program called "Radiant Technology," headquartered at Wright-Patterson Air Force Base, with its operational home at the Redstone Rocket Range in Alabama. Sheehan stated that the program — known as Prompt Global Strike — was attempting to apply recovered craft technology to propel American nuclear missiles capable of being "launched stateside and hit into the center of China or Russia within 2 minutes." Sheehan characterized the weaponization impulse: "these guys live in the world of, as soon as they see, oh, a crash UFO man, we can make a weapon out of that."
Corso's Art Bell interview (1997)
In a radio interview with Art Bell, Corso confirmed publicly that his radars had directly tracked anomalous objects over White Sands during his command of the range battalion: "There were some experiences that happened. My radars were picking up objects at White Sands when I commanded the range battalion. Traveled three or 4000 miles an hour." This public statement — made on one of the most widely heard radio programs of the 1990s — moved Corso's radar-interference thesis from a classified footnote in a memoir to a mainstream media claim, generating the wave of press attention that contributed to Congressional testimony sessions on the Roswell file in subsequent years.
How it became known
The radar-interference shootdown hypothesis first appeared in published form in Corso's The Day After Roswell (1997). The principle — that high-powered targeting radar could interfere with electromagnetic navigation systems — was corroborated circumstantially by the pattern of contemporary radar tracking records from the 509th, Alamogordo, and White Sands, first reviewed in their classified form by Corso at the Pentagon in 1961. The Ramstein 1974 claim has not been independently corroborated in open sources, but is consistent with the overall model Corso describes for targeting radar interference. The Guy Hottel FBI memo of 1950 provided the earliest known official documentation of the radar-interference theory, predating Corso's public account by nearly five decades. Harris's Conversations With Colonel Corso (2017) added Corso's unpublished private accounts of electromagnetic pillars and direct contact with a non-human being who confirmed radar's disabling effect. Malmgren's deathbed disclosures, reported posthumously via Jesse Michels, connected the radar-interference vulnerability to the deliberate weaponization program that ran from Operation Dominic through the Strategic Defense Initiative. Michael Salla's academic work on exopolitics and SDI has provided the most sustained secondary analysis of Corso's claims about the anti-extraterrestrial rationale for directed-energy weapons development.
Disclosure Project witness testimony
Multiple witnesses assembled by the Disclosure Project in 2001 independently corroborated the deliberate-shootdown thesis. Master Sergeant Dan Morris, a retired USAF career noncommissioned officer who was recruited into the National Reconnaissance Office and held what he described as a "cosmic top-secret clearance, thirty-eight levels above top secret," stated directly that "our military deliberately caused the 1947 ET craft crashes near Roswell" and that the military "captured one of the ETs, which they kept at Los Alamos for three years, until he died." Morris warned that continued weaponization against ET craft "could force them to retaliate, and that would be our destruction."
A scientist and engineer identified only as "Dr. B.," who had worked on anti-gravity, chemical warfare, and "extremely high-energy space-based laser systems and electromagnetic pulse technology," confirmed "direct knowledge of the fact that certain groups have used these space-based systems to successfully shoot down extraterrestrial spacecraft and their occupants."
A former Boeing surface technician identified as "A.H.," whose contacts spanned the NSA, CIA, NASA, JPL, and NRO, reported that "a group in the FBI discovered that radar testing was causing interference with some of the ETVs and that this was what was causing so many crashes." A.H.'s CIA contact separately confirmed that "the USAF had shot down some of these spacecraft." General Curtis LeMay personally "confirmed the ETC crash at Roswell" to A.H.
ET interception of human weapons
The relationship is not one-directional. Disclosure Project witness Air Force Colonel Dedrickson of the Atomic Energy Commission reported that the United States attempted to detonate a thermonuclear weapon on the Moon; when the missile went exo-atmospheric, it was allegedly intercepted by an extraterrestrial vehicle and dematerialized before reaching its target. Greer also states that at least one human-made classified exotic vehicle was downed in Iran and had to be retrieved by a U.S. operation — illustrating the global operational reach of these programs.
