19–20 November 1945: A Bell-Atlanta B-29B-60-BA Superfortress, 44-84061, named Pacusan Dreamboat, piloted by Colonel Clarence Shortridge Irvine and Lieutenant Colonel G.R. Stanley, flew non-stop and unrefueled from Guam, the largest and southernmost island in the Mariana Islands of the Western Pacific, to Washington, D.C. The four-engine heavy bomber covered the 8,198 miles (13,193 kilometers) in 35 hours, 5 minutes. It set a Fédération Aéronautique Internationale (FAI) record for Distance in a Straight Line: 12,739.59 kilometers (7,916.01 miles).¹
Pacusan Dreamboat was modified specifically for a series of long-distance flights. A standard production B-29B, a light-weight variant of the Boeing B-29 Superfortress, it did not have the four power gun turrets with their .50-caliber machine guns. A radar-directed 20 mm cannon and two .50-caliber machine guns in the tail were the only defensive weapons. Much of the standard armor plate was also deleted. It weighed 69,000 pounds (31,298 kilograms) empty and 137,000 pounds (62,142 kilograms) fully loaded. Pacusan Dreamboat was further lightened. The tail guns were removed and the tail reshaped. It had an empty weight of 66,000 pounds (29,937 kilograms). Its takeoff weight on this flight was 151,000 pounds (68,492 kilograms).
Pacusan Dreamboat carried a 12-man crew and 10,000 gallons (37,854 liters) of gasoline.
Pacusan Dreamboat set a number of distance and speed records, including Honolulu, Hawaii to Cairo, Egypt and Burbank to New York in 5 hours, 27 minutes, averaging 451.9 miles per hour (727.26 kilometers per hour).
The Pacusan Dreamboat was stricken from the Air Force inventory 8 August 1954 and reclaimed at Tinker Air Force Base, Oklahoma City, Oklahoma.
1 November 1954: The United States Air Force begins to retire the Boeing B-29 Superfortress from service. In the above photograph, B-29A-20-BN 42-94012 is at the aircraft storage facility, Davis-Monthan Air Force Base, Tucson, Arizona, “The Boneyard.” The dry desert climate and hard, alkaline soil make the base ideal for long-term aircraft storage. The Santa Catalina Mountains are in the background.
The B-29 Superfortress was the most technologically advanced—and complex—aircraft of World War II. It required the manufacturing capabilities of the entire nation to produce. Over 1,400,000 engineering man-hours had been required to design the prototypes.
The Superfortress was manufactured by Boeing at Seattle and Renton, Washington, and Wichita, Kansas; by the Glenn L. Martin Company at Omaha, Nebraska; and by Bell Aircraft Corporation, Marietta, Georgia.
There were three XB-29 prototypes, 14 YB-29 pre-production test aircraft, 2,513 B-29 Superfortresses, 1,119 B-29A, and 311 B-29B aircraft. The bomber served during World War II and the Korean War and continued in active U.S. service until 1960. In addition to its primary mission as a long range heavy bomber, the Superfortress also served as a photographic reconnaissance airplane, designated F-13, a weather recon airplane (WB-29), and a tanker (KB-29).
The B-29 was operated by a crew of 11 to 13 men. It was 99 feet, 0 inches (30.175 meters) long with a wingspan of 141 feet, 3 inches (43.068 meters). The vertical fin was 27 feet, 9 inches (8.305 meters) high. The wings had a total are of 1,720 square feet ( square meters). The angle of incidence was 4° with 4° 29′ 23″ dihderal. The leading edges were swept aft 7° 1′ 26″. The bomber’s empty weight was 71,500 pounds ( kilograms) with a maximum takeoff weight of 140,000 pounds ( kilograms).
The B-29 was powered by four air-cooled, supercharged, 3,347.66-cubic-inch-displacement (54.858 liter) Wright Aeronautical Division Cyclone 18 (also known as the Duplex-Cyclone) 670C18BA4 (R-3350-23A) two-row 18-cylinder radial engines, which had a Normal Power rating of 2,000 horsepower at 2,400 r.p.m., and 2,200 horsepower at 2,800 r.p.m. for takeoff. They drove 16 foot, 7 inch (5.055 meter) diameter, four-bladed, Hamilton Standard constant-speed propellers through a 0.35:1 gear reduction. The R-3350-23A was 6 feet, 4.26 inches (1.937 meters) long, 4 feet, 7.78 inches (1.417 meters) in diameter and weighed 2,646 pounds (1,200 kilograms).
The maximum speed of the B-29 was 353 knots (406 miles per hour/654 kilometers per hour) at 30,000 feet (9,144 meters), though its normal cruising speed was 198 knots (228 miles per hour/367 kilometers per hour) at 25,000 feet (7,620 meters). At its maximum takeoff weight, the B-29 required 1 hour, 1.5 minutes to climb from Sea Level to 20,000 feet (6,096 meters). The bomber’s service ceiling was 43,200 feet (13,167 meters). The combat range was 3,445 nautical miles (3,964 statute miles/6,380 kilometers) and its maximum ferry range was 4,493 nautical miles (5,170 statute miles/8,321 kilometers).
The Superfortress could carry a maximum of 20,000 pounds (9,072 kilograms) of bombs in two bomb bays. For defense it had 12 Browning M2 .50-caliber machine guns in four remote-controlled turrets and a manned tail position. The B-29 carried 500 rounds of ammunition per gun.
A number of B-29 Superfortresses are on display at locations around the world, but only two, the Commemorative Air Force’s B-29A-60-BN 44-62070, Fifi, and B-29-70-BW 44-69972, Doc, are airworthy. (After a lengthy restoration, Doc received its Federal Aviation Administration Special Airworthiness Certificate, 19 May 2016.)
