The Howze Board was the informal name of the Tactical Mobility Requirements Board created at the direct request of Secretary of Defense Robert McNamara to review and test new concepts integrating helicopters into the United States Army. What became known as airmobility within the United States Army was a direct result of the Howze Board's findings. It was named after its chairman, Hamilton H. Howze.
The roots of the Howze Board may be found in the 1960 Army Aircraft Requirements Review Board (commonly referred to as the Rogers Board, after its chairman, Lieutenant General Gordon B. Rogers). The Rogers Board concentrated on evaluating aircraft designs (both helicopters and light fixed wing designs) for the Army and did not develop plans for their operational use, focusing instead on design issues and the question of how often replacement designs should be considered. It did recommend that an operational use study be considered, and mentioned the possibility of creating a unit to test operational concepts. Both these suggestions would find expression in the Howze Board.
The Howze Board was also shaped by the growing conflict in South Vietnam and tensions between the Army and Air Force regarding the Army's aviation program in general. Under earlier agreements, the Army could only operate aircraft under certain weight and size restrictions. There were also limits placed on arming such aircraft. The Air Force focused its objections on Army fixed wing aircraft (the OV-1 Mohawk and Caribou), and the Caribou was transferred to the Air Force in 1966. Before the Howze Board "the Caribou and the Mohawk were the two major symbols of Army-Air Force disagreement and more time was devoted to these systems than to the entire mobility concept itself."
International events and changes in the defense policy of the United States also played a role in the formation of the board. President John F. Kennedy's Secretary of Defense, Robert McNamara, began his own review of the Army's plans for aviation in late 1961 and came to the conclusion that the Army's plan was perhaps not aggressive enough in light of recent events (South Vietnam, the Berlin crisis, and even the Army's own reorganization of its divisions). Feeling that the Army's response to his concerns was still too cautious, he took the unusual step of directing the Secretary of the Army to form a board to review the Army's plans for aviation (especially helicopters) with a fresh approach (a "new look"). This approach was to ignore past policies and restrictions, and shift from ground-based systems to airmobile systems "if it would improve capabilities and effectiveness." McNamara's memo also named the individuals he wished to conduct this review, giving the Secretary of the Army no room to place his own appointees. Finally, McNamara indicated that he wanted the board to use field tests and exercises to validate its recommendations.
