DOW-UAP-D099, Intelligence Review of “Ghost Rocket” Incidents, 1947
This document is a U.S. Department of War General Staff intelligence review assessing incidents involving unidentified “Ghost Rockets” reported over Sweden and other Scandinavian countries beginning in May 1946. The review includes an analysis of observational reports, statements from the Swedish government, and reporting from the U.S. military attaché in Stockholm. The review highlights the inconclusive nature of the contemporary evidence available to substantiate reports from civilian and military observers. The review also documents a change in the public stance of the Swedish Defense Staff, which privately attributed the objects to Soviet V-1 missile tests launched from Peenemünde. Peenemünde is a then-occupied municipality in northeastern Germany that had been associated with the development of the V-1 and V-2 rocket program during World War II. The Swedish assessment publicly shifted from an unknown technological origin to one of a “celestial origin.” The review suggests that this shift was a deliberate effort to avoid diplomatic conflict with the Soviet Union. The report’s final assessment concludes that while most reported incidents were likely misidentified natural phenomena, the “best evidence” suggested a small number of “real incidents” involving low-flying V-1 type missiles, likely attributable to Soviet tests of captured German technology.

FEATURE SECTION "GHOST ROCKETS" OVER Flying missiles were first reported over southern Sweden in late May 1946 by the press, which gave the missiles the name of "Ghost Rockets." In June, the missiles also had been reported over Finland and Denmark. By July, the number of sightings over Sweden had greatly increased, and several also had been reported over Norway. The great majority of these reports were made by untrained observers and, as would be expected, varied widely in the description of the actual missiles as well as, of their course, altitude, and speed. Descriptions of the Missile The two most common descriptions of the missiles were "a ball of fire with a tail" and a "shiny cigar-shaped object." The reported direction of flight covered all points of the compass, with a northerly direction being slightly pre dominant. Variations in altitude ranged from treetop height to 160,000 feet, the higher altitudes almost exclusively being reported from Finland. Speeds reported were from 65 m. p. h. to ''lightning fast," with the majority described as having great or very great speed. The missiles generally have been described in horizontal flight; a few have been reported as diving into the ground or into lakes, or exploding in the air. In no case have fragments been found other than bits of material described as "nonmetallic slag." One of the few reports available from an individual who should be more reliable and competent than the average

GHOST ROCKETS ..sBORB'F layman is that of a Swedish Air Force pilot. On 14 August, at 1000 hours, he was flying at 650 feet over central Sweden when he saw a dark, cigar-shaped object about 50 feet long and 3 feet in diameter flying 200 feet above and approxi mately 6,500 feet away from him at an estimated speed of 400 m. p. h. The missile had no visible wings, rudder, or other projecting part; and there was no indication of any flame or Jight as has been reported in the majority of other sightings. His report states that the missile was maintaining a constant altitude over the ground and, consequently, was following the large features of the terrain. The last state ment casts doubt on the reliability of the entire report be cause of the inability of a missile, without wings, to maintain a constant altitude over hilly terrain. However, the pilot does imply that there may have been wings which he was unable to see, because he stated that it could not have been a Swedish jet plane as there was none flying in the vicinity at that time. The Scandinavian press, with the exception of the Com munist papers, initially reported the incidents in some detail and openly attributed them to missiles fired by the U. S. S. R. In August, a partial censorship was imposed on the press, restricting the publication of exact details or localities where missiles were seen. The Communist press has continued to ridicule the entire matter and claims that there was no basis for the reports that the missiles were of Soviet origin. In fact, a charge was made that they came from the United States and that Gen. Doolittle was sent over to observe the effects of the missiles I Official Investigations Official investigations of these reports were begun by the Swedish authorities in June. The Defense Staff requested the public to report any unusual observations, and by the

8ElCRET GHOST ROCKETS end of July almost 1,000 such reports had been received. The investigation has been carried out by the Swedish Defense Staff in a very peculiar manner. In the beginning, many of the key personnel were on summer leave, and they were not recalled to deal with the problem. Spokesmen for the Defense Staff repeatedly have told the United States Military Attache that they definitely believed there were rockets over Sweden, and that they were launched by the Soviets from Peenemtinde on the German Baltic coast. However, they have not been able to produce any evidence to support these statements. To date, no United States military or naval personnel in Sweden have seen any frag ments, points of impact, or other direct evidence to prove that guided missiles have appeared over Sweden. The official communiques issued to the press by the Defense Staff have not reflected the same tone as the state ments made by individual officers in conversations. In fact, the communiques themselves have varied. The last one, issued on 10 October, very strongly indicated that the great majority of the reported incidents were of celestial origin, which is a complete change from the one of 6 August when it was reported that, except in a few cases, they could not be Attitude of Swedish Officials To arrive at any definite conclusion from the conflicting evidence available on these reported missiles is impossible. The contradictory attitude of Swedish officialdom would tend to indicate that it was doing very little to arrive at a definite conclusion, perhaps for political purposes. The com plete change in attitude between the communiques issued on * In September and October, flying objects were reported over widely separate points in Europe and Africa, including Belgium, Greece, Italy, Morocco, and Austria. In the main, these reports have not been confirmed and appear to be due to explainable ca.uses, such as meteors or Very flares, fireworks, etc.

GHOST ROCKETS 8:SORR1' 6 August and IO October indicates that the Swedish Staff was trying to minimize the entire matter which had grown to such a size that the Staff was afraid of its having official repercussions on Swedish-Soviet relations. The Soviets are known to be working on various guided missiles. They have the ability to produce, and probably have tested, missiles of the V-1 type. Without warheads and with slightly improved motors, these missiles could have a range of 500 miles, and are the only available German missiles believed capable of horizontal flight at low altitudes. There is some evidence that such work has been carried out
Where this file fits in the PURSUE archive
This file is one of DoD's 257 files in the Trump PURSUE disclosure. Within the DoD agency block it ranks #156 of 257 by Anomalousness Index. Across the entire 450-file archive it ranks #280 of 450.
That places it in the lower-scoring band of the archive (280 of 450 by score), typical of investigative-record style files where the report is paper-based rather than instrumented.
Anomalousness Index: 56/100
Evidentiary weight that this encounter remains unexplained after conventional analysis. Not a probability of extraterrestrial origin - that number is not honestly computable from the released files and this tracker refuses to publish it.
🤖 AI-ASSISTED SCORING · methodology
The six rubric components break down for this file as follows. Each component has a weighted contribution to the final score; the per-component explanation below describes what this file's particular value on that component means in the rubric's framework.
Reported by a witness with no instrumented record. The lowest tier in the rubric's sensor axis. Eyewitness perception in field conditions, even when the witness is highly credentialed, scores below capture by any instrumented modality. This report reached the federal record through the Department of War.
Trained U.S. military personnel reporting from an operational mission context. A high witness-credibility tier, ranked in the rubric below astronaut, trained-aviator, and federal-agent testimony. This is the witness profile shared by the entire AARO-submitted infrared-capture cluster that anchors the 66-point score band.
Single-witness or single-instrument capture. This is the corroboration tier for the overwhelming majority of the PURSUE archive on the released metadata - the rubric records the honest limit of the underlying record rather than inferring multi-witness corroboration that the released summaries do not establish. A small number of files with an independent second witness or instrument score on the multi-witness/multi-instrument tier above this one.
No kinematic measurements - speed, acceleration, vector - are published in the released file with sufficient precision to score on the kinematic axis. The rubric does not infer kinematic anomaly from narrative observer estimates. Every file in the archive carries this value, which is itself an observation about the disclosure: kinematic-grade telemetry was not part of what was released.
A conventional candidate explanation has been considered but is not dispositive. Every file in the archive scores this way - reflecting that the underlying release metadata systematically caveats strong determinations in either direction. The released summaries warn against reading them as conclusive analytical judgments, and the rubric respects that.
Released as open after formal review by the originating agency. The file passed through a review process and was published in that posture - a stronger disposition signal than 'unresolved with no review,' because review has occurred and the open status is the agency's published conclusion.
Bottom line on the score: the Anomalousness Index of 56/100 reflects evidentiary weight that this specific file's encounter remains structurally unexplained by the rubric's six axes - it is not a claim that the underlying event involved anything non-conventional, and it is not comparable across rubrics that use different weights.
