The 307th Bombardment Group (Heavy) was activated in 1942 by the Army Air Corps Combat Command after an attack on Pearl Harbor thrust the United States into war with Japan. In succeeding years, the 307th’s participation in World War II, the Korean Conflict, and the Vietnam Conflict proved it to be one of the most renowned bombing units in military annals.

On April 15, 1942, the 307th began operations as a B-17 Flying Fortress bomber unit at Geiger Field, Washington. Its first mission to guard the northwestern United States and Alaskan coasts against armed invasion prepared the group for its later role in the Pacific Theater of World War II. After patrolling the coastline of America for five months, the 307th’s B-17s were replaced with the famous B-24 “Liberators.” Subsequently, the entire unit was transferred to Sioux City, Iowa, for a brief training period. After completing a three-week familiarization program, the 307th relocated its entire cadre and 35 bombers to Hamilton Field, California.

Three days later, the B-24s were deployed to Oahu in the Hawaiian Islands. An old Norwegian freighter slowly transported the remainder of the group to its “Pacific Paradise.” Upon arrival at Oahu, each of the group’s four squadrons was assigned to different Hawaiian locations; the 370th to Kipapa, the 371st to Wheeler Field, the 372nd to Kabuka, and the 424th to Mokaleia. Headquarters for the 307th was centered at Hickam Field. Finally settled at Oahu, 307th bombers began to search and patrol missions over the surrounding Pacific area. Maintaining a 24-hour vigil, the bombers were to avert any naval attack against the Hawaiian Islands. Stations were eventually set up on Espiritu Santo, New Hebrides, on Jan 13, 1943; Guadalcanal, Solomon Islands, on Aug 20, 1943; Los Negros, Admiralty Islands, on Jun 1, 1944; Wake Island on Sep 3, 1944; Morotai, New Guinea on Oct 17, 1944, and Clark Field, Luzon, the Philippines on Aug 27, 1945.

Group bombers received their first taste of combat on December 27, 1942. Twenty-seven of the group’s aircraft were deployed from Oahu to Midway Island. From here, the B-24s staged their first attack against an enemy fortress on Wake Island. The enemy was taken by surprise during the predawn raid. Before Japanese units responded with a barrage of anti-aircraft fire, 307th bombers had blasted 90 percent of the Wake stronghold. All aircraft returned safely from what was considered the longest mass raid of that time. It was from this and succeeding long-distance combat missions that the 307th Bombardment Group became known as the “Long Rangers.”

The 307th moved to Guadalcanal in February 1943. From their new location on the largest of the Solomon Islands, Group bombers attacked fortified Japanese airfields and shipping installations within the Southwest Pacific. At Guadalcanal, the 307th Bombardment Group was subjected to massive air attacks by enemy bombers and fighter aircraft. On a warm day in March 1943, three waves of Japanese planes blasted the airfield, causing the greatest number of 307th casualties during the war.

November 11, 1943, the 307th participated in the largest aerial strike of the South Pacific War. In conjunction with the United States naval elements, group bombers pounded enemy war and merchant ships at Rabaul, New Guinea. Amidst swarms of Japanese “Zeros” and heavy anti-aircraft fire, 307th aircraft released their bombs, leaving the port of Rabaul in complete ruin.

Throughout the remainder of the war, the 307th aircraft continued to cripple the debilitated enemy. Group elements neutralized Japanese forces at Yap, Truk, Palau, Balikapan, and the Philippines. Bombing strikes against Japanese shipping centers in the Philippines inhibited the enemy from gaining a further stronghold in the area. An unescorted attack by group aircraft against oil refineries at Balikpapan, Borneo, on October 3, 1944, helped assure an allied victory in the South Pacific.

Following V-J Day, 1945, the 307th aircraft ferried former American war prisoners from Okinawa to Manila. No longer needed, the group returned to the states in December 1945 and was subsequently deactivated. With barely time to form cobwebs, the 307th Bombardment Group was reactivated on August 4, 1946, and is still active today.

While in the Pacific, the 307th was awarded two Distinguished Unit Citations, one for an air strike against Truk on March 29, 1944, and another for a strike against the refineries at Borneo on October 3, 1944. The group was also awarded the Philippine Presidential Unit Citation for its active role in the Philippines campaign.

About the 307th Bomb Group—Did you know? The story of the 307th Bomb Group “Long Rangers” in World War II is an impressive one.

  • It was January 1943 when the unit was credited with its first Japanese Zero. The 307th Bomb Group gunners shot down an average of 25 percent of their Japanese fighter interceptors. 307th Bomb Group Crews encountered coordinated and concentrated interception by Japanese airmen over many Japanese-held islands without their own fighter escorts, including Rabaul, Truk, Yap, Palau, Balikpapan, and the Philippines.
  • Their first taste of combat came on Dec 24th, 1942, when 27 aircraft flew 1,260 miles to bomb selected targets on Wake Island. All planes returned safely from the flight after having flown 2,240 miles, the longest mass raid of the war to that time. As a result of this mission and the many long-distance flights to come, the 307th Bombardment Group (HV) soon became known as the “Long Rangers.”
  • The Group’s aircraft was the first over Tarawa, Naura, Ocean Island, the Marshall Islands, Corregidor, P.I., and the 307th BG was the first heavy bomber group to be tasked with the bombing of an enemy naval fleet.
  • Two Distinguished Unit Citations were awarded to the Group, one for action in the bombing of the Island of Truk, the most heavily defended and strongly fortified Japanese base in the Pacific. During withdrawal. Gunners of the Group destroyed 31 of the 75 attacking aircraft, probably destroyed 12 more, and damaged 10 in an air battle that lasted 43 minutes. This daring raid, made on 29 March 1944, neutralized the Island's airfields, making possible long-range flights without fighter protection. A 2nd Distinguished Unit Citation was awarded for the successful strike at the Balikpapan Oil Refineries in Borneo on 03 October 1944. The 307th had to fly their B-24 Liberator bombers for 17 1/2 hours for a round trip of 2,610 miles, the longest mass daylight mission ever flown by this type of aircraft.
  • They hit the Japanese in the air. They shot down 355 planes, 68 probable’s and 51 damaged. On the ground, they destroyed 170 airplanes, scores of airfields and supply dumps, oil refineries, and harbor installations. On the sea, they sunk 21,000 tons of shipping and damaged another 112,000 tons.
  • In November 1945, the 307th Bomb Group was deactivated, but with the Air Force’s Policy of preserving the names of the top fighting units of World War II, the 307th Bomb Group was reactivated as the 307th Bombardment Wing on 4 August 1946. Assigned to MacDill Air Force Base, Florida, and furnished with B-29 Aircraft. The 307th Bomb Wing took part in all Strategic Air Command Operations until the outbreak of the Korean War in July 1950.
  • They had a successful campaign in Korea and received another Distinguished Unit Citation for their extraordinary heroism in action against an enemy of the United Nations during the period of 11 to 27 July 1953. At this time, they flew 93 sorties and dropped 860 tons of bombs on targets at the Samanyu Air Field, where despite severe icing, intense enemy anti-craft fire, and coordinated search light fighter opposition, they rendered the airfield unserviceable.
  • During the course of the Korean operations, the Wing mounted 6,052 sorties against enemy targets. Flew 55,473 combat hours and dropped 51,757 tons of bombs.
  • The 307th Bomb Wing returned to the United States in 1954. The 307th Bomb Wing, the last remaining B-29 Wing in the Far East, returned in October 1954 to be equipped with the B-47 Stratojet bomber and reassigned to the new duty station at (Click this link-->)Lincoln Air Force Base, Nebraska
