Professional military education, August 1994 to May 1995. Required for advancement to senior officer ranks.

Service record

34-year career timeline

Highlighted entries mark assignments with direct relevance to the UAP/SAP investigation. Critical entries mark the two positions most central to the case.

Oct 1980 — Mar 1984

Payload Development Engineer, SAF/SP Office of Special Projects-6

Los Angeles AFB, California

First assignment. Classified satellite payload development under the Secretary of the Air Force's black-world office — the Air Force's interface with the National Reconnaissance Office.

Apr 1984 — Jun 1985

Chief, Payload Systems Division, Office of Special Projects-8

Los Angeles AFB, California

Promoted to division chief within the classified satellite enterprise at age ~27. Early indicator of fast-track status within NRO programs.

Jul 1985 — Sep 1988

Doctoral Student, MIT (Hertz Fellow)

Cambridge, Massachusetts

Three-year break for PhD. Married Susan Wilkerson in April 1985. Hertz Fellowship is among the most selective in applied science.

Oct 1988 — May 1992

Assistant Director, Systems Engineering, Office of Special Projects-13

Los Angeles AFB, California

Returned to classified satellite work at a more senior level. Sources note he received "large program leadership responsibilities" within the classified development units.

Jun 1992 — Jul 1994

Director, Mission Planning, Aerospace Data Facility

Buckley AFB, Colorado

Shifted to operations side. Aerospace Data Facility is a signals intelligence ground station — part of the NRO/NSA infrastructure.

Jun 1995 — Aug 1997

Commander, Operations Squadron, Aerospace Data Facility

Buckley AFB, Colorado

Returned to Buckley as squadron commander after Air War College. First command assignment.

Aug 1997 — Mar 2000

Chief Engineer, Navstar GPS Joint Program Office

Los Angeles AFB, California

Senior technical leadership of the GPS constellation program. First major non-classified assignment in the public record.

Apr 2000 — Sep 2001

System Program Director, Space Based Laser Project Office

Los Angeles AFB, California

Directed the Space Based Laser program — a directed-energy weapons system intended for orbital deployment. Bridges the space and directed-energy threads that define his later career.

Oct 2001 — May 2004

Director, AFRL Space Vehicles Directorate / Commander, Phillips Research Site

Kirtland AFB, New Mexico

First Kirtland assignment. Combined Space Vehicles + Directed Energy research under one command. This is when he enters the New Mexico ecosystem — Sandia, Kirtland, the foothills — that would become the geography of his disappearance 22 years later.

Jun 2004 — Oct 2005

Vice Commander, Ogden Air Logistics Center

Hill AFB, Utah

Logistics and sustainment command. Broadening assignment en route to general officer ranks.

Oct 2005 — Jun 2007

Vice Commander, Space and Missile Systems Center

Los Angeles AFB, California

Second-in-command of the Air Force's primary space acquisition organization. Promoted to Brigadier General (Dec 2007).

Jun 2007 — Jun 2009

Director, Space Acquisition, Office of the Under Secretary of the Air Force

Pentagon, Washington, D.C.

Pentagon-level oversight of all Air Force space acquisition. Transition toward the policy/oversight roles that follow.

Jun 2009 — May 2011

Director, Special Programs, OUSD(AT&L) / Executive Secretary, SAPOC

Pentagon, Washington, D.C.

The most sensitive assignment in this dossier. The Special Access Program Oversight Committee provides administrative visibility into every SAP across the entire Department of Defense — acquisition, intelligence, and operations. If any UAP-related programs exist within the SAP framework, this office would be in the oversight chain. Promoted to Major General.

May 2011 — Oct 2013

Commander, Air Force Research Laboratory

Wright-Patterson AFB, Ohio

Final command and capstone assignment. AFRL manages a $2.2B S&T portfolio across materials, sensors, propulsion, directed energy, space vehicles, and information. 10,800+ personnel. Wright-Patterson's institutional lineage traces back to 1947 Wright Field — the documented destination of Roswell debris. McCasland arrived at this command with prior SAPOC-level visibility into classified programs.

Oct 2013 — c. 2021

Director of Technology, Applied Technology Associates / BlueHalo

Albuquerque, New Mexico

Post-retirement civilian role. ATA specializes in precision pointing, inertial sensing, space situational awareness, and directed-energy-adjacent systems — the same technology stack from his military career. Returned to the Albuquerque / Kirtland ecosystem. BlueHalo was subsequently acquired by AeroVironment (2025).

c. 2021 — Feb 2026

Co-founder, DBE Consulting LLC

Albuquerque, New Mexico

Defense consulting firm advising DoD and DoE clients. Business partner is James Tegnelia — former DTRA Director, DARPA Deputy Director, Defense Science Board member. Also served on the Kirtland Partnership Committee and Universities Space Research Association boards.

Investigative relevance

Why this profile matters to the case

Documented

Three decades inside classified space programs

From his first assignment in 1980 through retirement in 2013, McCasland spent the majority of his career inside NRO-affiliated offices, classified satellite development, and SAP oversight. This is not someone with peripheral exposure to black programs.

Documented

SAPOC gave him the widest possible aperture

The Executive Secretary role provided administrative oversight across every SAP in the DoD. If UAP-related programs exist anywhere in the classified structure, his office would have been in the chain.

Claimed

DeLonge describes him as the orchestrator

WikiLeaks emails place McCasland at the center of the advisory network that became TTSA. DeLonge describes him as "very, very aware" and credits him with assembling the team: Elizondo, Semivan, Puthoff, Weiss.

Inferred

The career pattern is unusually convergent

NRO satellites → SAPOC oversight → AFRL command at Wright-Patterson → civilian directed-energy work in Albuquerque. Every thread in this investigation maps onto a stage of his career. That convergence is either coincidence or legibility.

Disputed

The retirement qualifier

Susan's statement that he "retired nearly 13 years ago with only common clearances since" is a specific pushback against the idea that he remained operationally involved. But knowledge doesn't expire with clearances. Whatever McCasland learned during his SAPOC tenure remains in his memory regardless of his current access status.
