Air Intelligence Information Report: USSR Evaluated Aircraft Radar Tracks

This document is a collection of Air Intelligence Information Reports and related correspondence from the 314th Air Division, dated between February and March 1951. The primary content consists of detailed logs of radar tracks identified by the Wakkanai Radar Site near Sakhalin, Japan. These logs document numerous unidentified aircraft tracks detected during the night hours of February 21 and 22, 1951. The intelligence assessment explicitly identifies these tracks as Soviet aircraft. The reports highlight a notable increase in night-flying activity by Soviet forces compared to the period between March 1949 and February 1951. Analysts concluded that this trend suggested the Soviet military was either actively working to improve its night-flying proficiency or maintaining a high level of existing capability. In addition to the radar logs, the document contains internal correspondence regarding a separate matter involving a 'Flying Saucer' photograph. This photograph was submitted by an employee of the Allison Division of General Motors in Indianapolis, Indiana. The Technical Analysis Division of the Intelligence Department evaluated the image and concluded that the object in the photograph was likely an airplane model clipped from a magazine, and subsequently determined that no further action was required. The correspondence includes background checks on the employees involved in the photograph incident, noting their security clearances and potential connections to individuals in Washington, D.C., and Germany. The document is marked as 'CONFIDENTIAL' and includes instructions for its downgrading and eventual declassification after 12 years, in accordance with DOD Directive 5200.10.
