A new study by the Scientific Coalition for UAP Studies (SCU) has uncovered significant shifts in the behavior of Unidentified Anomalous Phenomena (UAP) from 1945 to 1975, suggesting these phenomena may involve intelligent actors with advanced technology.

Published on May 21, 2025, the study, titled “UAP Indications Analysis 1945-1975 Military and Public Activities,” provides fresh insights into UFO activities and their potential intentions.

The research, authored by SCU members Larry J. Hancock, Ian M. Porritt, Sean Grosvenor, Larry Cates, and Joshua Pierson, analyzes three decades of UAP incidents, revealing patterns that point to a focus on military atomic warfare facilities and a transition to nighttime interactions with the public.

Key findings include an early interest in atomic weapons sites, such as radioactive materials plants and Intercontinental Ballistic Missile (ICBM) facilities, with notable incidents like the 1967 Malmstrom event, where a UAP reportedly disabled multiple missile silos.

The study highlights a shift from high-visibility, daytime “display-type” activities—such as close approaches and radical flight maneuvers—in the 1940s and 1950s to more clandestine nighttime operations by the 1970s.

These later activities suggest possible human behavioral studies, with UAPs engaging in longer observations and closer approaches to small groups of witnesses.

The researchers also identified limited electronic communication attempts by UAPs, including coded Identification Friend or Foe (IFF) signals in 1957, hinting at an early contact protocol that later shifted away from overt engagement.
