James T. Lacatski is an engineer, former Defense Intelligence Agency (DIA) officer, and one of the founders of AAWSAP—Advanced Aerospace Weapon System Applications Program, a U.S. government–funded initiative into unidentified anomalous phenomena (UAP). He holds a B.S., M.S., and Doctor of Engineering degree in Nuclear Engineering, with expertise in directed‐energy systems, fusion plasmas, and missile threats. Before AAWSAP, Lacatski worked at the DIA’s Defense Warning Office, where he specialized in strategic foreign missile systems and annual missile threat assessments.

Lacatski proposed and marshaled the creation of AAWSAP around 2007, in partnership with colleagues and with support from Senator Harry Reid and others. The program was contracted to Bigelow Aerospace Advanced Space Studies (BAASS) in 2008, with Lacatski serving as Program Manager and Contracting Officer Representative. AAWSAP operated for about two to three years, employed roughly 50 full‐time investigators—many former military or law enforcement—produced tens of millions of dollars in research funding, and oversaw what supporters describe as the largest catalog of UAP‐related case reports compiled to that date.

Public accounts attribute to Lacatski a pivotal early experience: on visit to Skinwalker Ranch in Utah, he reportedly witnessed what he described as a “semi‐opaque, yellowish, tubular structure”—an observation that he considered technically anomalous and influential in shaping his belief that UFO phenomena might intersect with national security or advanced technology threat concerns. According to his words, some AAWSAP work went beyond observing sightings, extending into material studies, human effects, propulsion, power generation, and broader aerospace weapons research.

Where Lacatski’s role enters the ongoing disclosure debate is through these claims: that the U.S. government obtained and explored “craft of unknown origin,” sometimes without recognizable physical propulsion features; that AAWSAP wasan unusually large, technically detailed, but largely undocumented program; and that its records (including email archives) and relationships with later programs like AATIP and Kona Blue are contested or partially opaque. He has co-authored at least one insider book, “Skinwalkers at the Pentagon,” with Colm Kelleher and George Knapp, partially revealing what he says is previously untold detail about AAWSAP’s investigations and their significance.

Dr. Lacatski remains a figure of interest among researchers and policymakers exploring UAP because his claims challenge standard narratives: about the scale of government involvement, the technical scope of investigations, and the possibility that anomalies might represent something beyond conventional aerospace phenomena. His assertions are controversial and debated; what is confirmed by official records is limited, and many of his more extraordinary claims remain unverified.
