Project CHECO

Project CHECO. Initiated by the United States Air Force during the Vietnam War, this comprehensive effort was designed to create a contemporaneous historical record of air operations across Southeast Asia. Established under the auspices of the Pacific Air Forces and the USAF Historical Division, it involved teams of historians, analysts, and military personnel directly in theater. The project produced a vast collection of detailed, real-time reports that have become a foundational primary source for understanding the air campaigns over North Vietnam, Laos, and Cambodia.

Background and Establishment

The genesis of the project stemmed from a recognized need within the United States Department of Defense for immediate, accurate documentation of evolving combat operations. Following the escalation of U.S. involvement after events like the Gulf of Tonkin incident, senior commanders, including those at Headquarters Pacific Air Forces, sought to avoid the historical gaps experienced in prior conflicts like the Korean War. Formal establishment occurred in 1962, with its administrative center initially at Tan Son Nhut Air Base in South Vietnam. The effort was closely aligned with the broader mission of the USAF Historical Research Agency to capture lessons learned. Key early proponents included officers within the Office of the Secretary of the Air Force who understood the operational and historical value of such a program.

Objectives and Scope

The primary objective was to provide a definitive, factual account of air warfare for use by operational planners and future historians. Its scope was exceptionally broad, encompassing all major air campaigns, including Operation Rolling Thunder, Operation Linebacker I, and Operation Linebacker II. It also covered specialized operations such as the Ho Chi Minh Trail interdiction campaigns and close air support missions during pivotal battles like the Battle of Khe Sanh and the Siege of Plei Me. The project extended to documenting the activities of allied forces, including the Republic of Vietnam Air Force, and operations in neighboring theaters like the Secret War in Laos. Analysts focused on tactics, weapon systems performance, command and control structures, and the overall effectiveness of air power.

Operations and Reporting

Operations were conducted by dedicated CHECO teams, often composed of field historians and veteran aircrew, who were deployed to major bases such as Da Nang Air Base, Udon Royal Thai Air Force Base, and Nakhon Phanom Royal Thai Air Force Base. These teams conducted interviews with participants from units like the 8th Tactical Fighter Wing and the 366th Tactical Fighter Wing shortly after missions. They gathered raw data from sources including mission reports, National Security Agency signals intelligence, and Central Intelligence Agency estimates. The process emphasized speed and accuracy, with reports frequently classified under levels like Top Secret or Secret to protect sensitive sources and methods. This real-time documentation allowed findings to be rapidly circulated to commands including the Military Assistance Command, Vietnam and the Joint Chiefs of Staff.

Key Reports and Findings

The project produced hundreds of substantive reports that have provided critical insights. Seminal studies include detailed analyses of the Siege of Điện Biên Phu (1967), the use of B-52 Stratofortress bombers in Arc Light missions, and the complex air operations during the Easter Offensive. Key findings often highlighted challenges such as the limitations of air power against a decentralized enemy, the political constraints imposed from Washington, D.C., and the technological evolution of surface-to-air missile defenses employed by the People's Army of Vietnam. Reports on operations like Commando Hunt provided exhaustive data on sensor-guided interdiction, while studies of the Son Tay Prison raid captured lessons on special operations. These documents collectively offered a nuanced, often critical, assessment of strategy and effectiveness.

Legacy and Deactivation

The legacy is profound, as its archives serve as an indispensable resource for historians at institutions like the Air University and the Center for Air Force History. Its methodology influenced subsequent historical data collection efforts in conflicts such as the Gulf War. Following the Fall of Saigon and the end of direct U.S. combat involvement, the project was gradually phased out, with its final reports completed in 1975. The vast collection of documents was transferred to the custody of the Air Force Historical Research Agency at Maxwell Air Force Base. Today, these declassified reports are heavily cited in scholarly works, official histories like the United States Air Force in Southeast Asia series, and analyses by think tanks such as the RAND Corporation, ensuring its detailed chronicle of air war continues to inform military scholarship and doctrine.
