DOW-UAP-D099 Intelligence Review of Ghost Rocket Incidents, 1947

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.
Conclusions
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
at Stolp (in Polish-administered Germany) or on the Baltic
islands of Oesel or Dago. Three of the people reporting
sightings have mentioned the noise of an outboard motor,
a characteristic of the impulse duct motor used on the V-1
by the Germans; and one of them stated that what he saw
looked like the V-1 he had seen over London during the war.
Others have reported little or no sound, a condition which
may indicate the use of a turbo-jet instead of a pulse-jet.
The best evidence, at present, is that there have been only
2 or 3 real incidents, perhaps as many as 5 or 10, of low-flying
missiles of the V-1 type. The high-altitude missiles reported
seem definitely to have been meteors or fireworks. The
Swedish Defense Staff probably has taken advantage of the
situation for political purposes and allowed the newspapers
to make a big story out of the missiles, without admitting
that the Staff had any evidence to indicate that there actually
were any such missiles. This was done at a time when the
Swedish public was demanding reductions in defense expendi
tures.
