Cactus Air Power At Guadalcanal

This study examines the role of the CACTUS Air Force during the battle for Guadalcanal. Hurriedly planned and executed, Guadalcanal was the first U.S. ground offensive in the Pacific. Starting as an unopposed amphibious assault, the operation turned into a six-month-long air, land, and sea battle to secure the island. Operating from an expeditionary airfield, the U.S. Marine Corps employed air power as its primary means of defending the island. The CACTUS Air Force conducted the campaign with limited air assets and was plagued by a variety of critical shortages, yet it managed to play a key role in the U.S. victory. This study focuses on the specific contributions of airpower during this campaign. It examines the role of air power in reconnaissance, deep, close, and rear area air operations. It also examines the factors that influenced how air assets were employed and the changes in U.S. concepts about air operations that were made to conduct the air campaign. CACTUS planes assisted in defeating several major Japanese attacks. However, the daily presence and routine operations of the CACTUS Air Force were its key contributions. CACTUS Air’s most important contribution was its ability to deny the Japanese air superiority and disrupt their freedom of action in the lower Solomon Islands.

The campaign for Guadalcanal, which stretched from August 1942 until February 1943, centered on Henderson Field. The airfield was captured by the US on 8 August and placed into operation by 20 August. As long as the airfield was kept operational and stocked with sufficient striking power, the Japanese could not run convoys with heavy equipment and large amounts of supplies to the island. Instead, they were forced to rely on night runs by destroyers which could not carry enough men or supplies to shift the balance decisively against the American garrison on the island. The American air contingent on the island, named the 'Cactus Air Force', comprised Marine, Navy and Army Air Force units. It had the challenging mission of defending the airfield against constant Japanese attacks, and more importantly, of striking major Japanese attempts to reinforce the island. The mission of neutralizing Henderson Field fell primarily to the Imperial Navy's Air Force flying out of airfields in the Rabaul area. The units charged with this mission were among the most accomplished in the entire Imperial Navy with a high proportion of very experienced pilots and a superb air superiority fighter (the famous 'Zero'). However, the distance from Rabaul to Guadalcanal handicapped Japanese operations and their primary bomber was terribly vulnerable to interception. This book traces the air campaign from both sides and explores the factors behind the American victory and the Japanese defeat. The text is supported by full-colour illustrations and contemporary photography.

Using diary entries, interviews and first-hand accounts, this vivid narrative brings to life the struggle in the air over the island of Guadalcanal between August 20 and November 15, 1942. The battle of Guadalcanal was the first offensive operation undertaken by the US and its allies in the Pacific War. The three months of air battles between August 20, 1942, when the first Marine air unit arrived on the island, and November 15, when the last enemy attempt to retake the island was defeated, were perhaps the most important of the Pacific War. “Cactus,” the code name for the island, became a sinkhole for Japanese air and naval power, as they experienced losses that could never be made good. For 40 years, the late Eric Hammel interviewed more than 150 American participants in the air campaign at Guadalcanal, none of whom are still alive. These interviews are the most comprehensive first-person accounts of the battle assembled by any historian. More importantly, they involved the junior officers and enlisted men whose stories and memories were not part of the official history, and thus provide a unique insight. In The Cactus Air Force, Pacific War expert Thomas McKelvey Cleaver worked closely with Eric to build on his collection of diary entries, interviews and first-hand accounts to create a vivid narrative of the struggle in the air over the island of Guadalcanal between August 20 and November 15, 1942.

Operation KE explores the air combat that attended the Japanese evacuation of Guadalcanal in early 1943 —a topic which has hitherto received very little attention. Operation KE was successful largely because Japanese strategic planning and tactical execution was basically sound. The traditional view holds that the Japanese got away with the initiative largely because the Americans let them; the US Pacific high command felt it was not worth the effort to try and stop them. Letourneau contends that this was not entirely the case. He argues that the Cactus Air Force and Guadalcanal-based naval units did their best to disrupt the evacuation, still believing that the Tokyo Express was bringing reinforcements and supplies to the 17th Army. Other US forces in the South Pacific did make a half-hearted and questionably-executed attempt to stop the Japanese, but were bluffed into adopting a ""wait-and-see"" posture. Operation KE focuses on the air war fought between the Cactus and US 13th Air Forces on the one hand and the Japanese Navy and Army Air Forces on the other, from mid-December, 1942 to mid-February, 1943. The book scrutinizes the US air strikes against the six KE-related Tokyo Express destroyer runs, plus related air strikes against the Japanese merchant marine, as well as air and naval base-suppression missions undertaken by both sides, to determine what actually happened in order to analyze why the Japanese evacuation succeeded and why Cactus failed to stop it. Background chapters attempt to assess the respective states of readiness of the Japanese and US air arms in the South Pacific to support on the one hand and counter on the other the execution of Operation KE. The central portion of the book narrates in some detail what actually occurred in the air and at sea -—including air strikes, fighter sweeps, base suppression missions, and naval sorties -—during the crucial prelude to and the actual playing out of the interrelated events that comprised the evacuation operation. Concluding chapters analyze, on both strategic and tactical levels, the Japanese planning and execution of Operation KE, and Cactus' initiatives to interdict KE's successful prosecution. The authors conclude that both the Japanese and the American states of readiness on the eve of Operation KE suffered in such matters as optimizing both resources and operating procedures, and combating a hostile environment. Consequently, both combatants were somewhat handicapped in their abilities respectively to carry out and contest Operation KE. The author contends that the Japanese developed a reasonably sound strategy that exploited those methods and tools of war then in use in the South Pacific; to achieve success, they maximized their own strengths while taking advantage of their adversary's limitations. Contrary to the traditional view, the authors are of the opinion that Japanese utilization of their newly-built airstrip at Munda in the Central Solomons played an important role in the success of Operation KE, which was in keeping with the long-range intention of developing Munda and Vila airstrips as major forward airbases to defend against any Allied push toward Rabaul through the Solomons. The U.S., on the other hand, by consistently misreading Japanese intent regarding Operation KE and pursuing a cautious offensive strategy, blunted the tactical impact of their initiatives to counter the evacuation. Several imprudent tactical decisions and a misallocation of resources further diluted the strength of US efforts."

A Marine flying ace and Medal of Honor recipient’s firsthand account of aerial combat in World War II’s Pacific theater. Young Jefferson J. DeBlanc always played cowboys and Indians dressed in a Captain Eddie Rickenbacker flying suit and Sam Browne belt and goggles. From his early childhood, he was fascinated with planes, and when he enrolled in Southwestern Louisiana Institute (now the University of Louisiana at Lafayette), he studied and excelled in pilot training. DeBlanc first saw action in World War II at the island of Guadalcanal in the South Pacific. From his very first day there, he proved himself as a talented fighter pilot. He shot down two Betty bombers on his first day and soon began to lead his own squadron in the air. Within weeks, he was part of the flying elite, the Marine Fighter Aces. The Guadalcanal Air War is DeBlanc’s firsthand account of his training and the events on Guadalcanal. It is DeBlanc’s journey as a man as he discovers the value of life, including his own. Because of the efforts of men like DeBlanc, the battles fought on and above Guadalcanal marked a turning point in the war and ended Japanese expansion. “A gallant officer, a superb airman, and an indomitable fighter . . . [He] rendered decisive assistance during a critical stage of operations.” —Harry S. Truman, Medal of Honor Citation
