The size of the bomb was constrained by the available aircraft, which were investigated for suitability by Norman Foster Ramsey. The only Allied aircraft considered capable of carrying the Fat Man without major modification were the British Avro Lancaster and the American Boeing B-29 Superfortress. [21] [22] [23] At the time, the B-29 represented the epitome of bomber technology with significant advantages in Maximum takeoff weight, range, speed, flight ceiling, and survivability. Without the availability of the B-29, dropping the bomb would likely have been impossible. However, this still constrained the bomb to a maximum length of 11 feet (3.4m), width of 5 feet (1.5m) and weight of 20,000 pounds (9,100kg). Removing the bomb rails allowed a maximum width of 5.5 feet (1.7m). [22] The 2010 Fat Boy Lo motorcycle is a new riff on one of the greatest hits to ever roll out of the Harley-Davidson design studio. Darker and lower than that original icon of fat-custom style, the Fat Boy Lo retains the bold presence of the Fat Boy while offering a fresh interpretation of the motorcycle that still defines the segment. In 1999 a new 1,450cc (88cuin) Twin Cam engine for the 2000 model year was used. This necessitated a bespoke engine variant and changes to the frame.

By Harley standards, it is not a heavy bike, the 330 kg’s (727 lbs) is greatly moved about and mastered again due to it’s low centre of gravity (all the weight is close to the ground versus a sport bike where engine and weight are positioned higher) and low, low seat. The target for the bomb was the city of Kokura, but it was found to be obscured by clouds and drifting smoke from fires started by a major firebombing raid by 224 B-29s on nearby Yahata the previous day. This covered 70% of the area over Kokura, obscuring the aiming point. Three bomb runs were made over the next 50 minutes, burning fuel and repeatedly exposing the aircraft to the heavy defenses of Yahata, but the bombardier was unable to drop visually. By the time of the third bomb run, Japanese anti-aircraft fire was getting close; Second Lieutenant Jacob Beser was monitoring Japanese communications, and he reported activity on the Japanese fighter direction radio bands.

Given the difference in displacement, it's no surprise that the H-D Twin Cam edges out the Suzuki mill at the dyno. The C90 produces 84.8 pound-feet at a low 2,800 rpm, and to be fair, that's a decent amount of torque that comes on very early. Still, the 103B takes the cake with 102.5 pounds of grunt at three grand. a b Nuke-Rebuke: Writers & Artists Against Nuclear Energy & Weapons (The Contemporary anthology series). The Spirit That Moves Us Press. 1 May 1984. pp.22–29. The original fat-custom icon commands the road with a steamroller stance. For 2022 its Lakester cast aluminum wheels are re-styled with 11 turbine-like spokes and an open center, and the classic Fat Boy® model tank badge is revised and now has a single trailing “wing” while retaining the centered star.

Robert Oppenheimer held conferences in Chicago in June 1942, prior to the Army taking over wartime atomic research, and in Berkeley, California, in July, at which various engineers and physicists discussed nuclear bomb design issues. They chose a gun-type design in which two sub-critical masses would be brought together by firing a "bullet" into a "target". [1] Richard C. Tolman suggested an implosion-type nuclear weapon, but the proposal attracted little interest. [2] A new seat is narrower, which along with the low seat height makes it possible for almost any rider to place both feet flat on the ground when the motorcycle is at rest. Now for the powerplants. The 103B in the Lo measures out at 1,689 cc for a slight size advantage over the 1,462 cc, C90 engine. Both run in a V-twin configuration; Harley in its typical 45-degree layout, and Suzuki with a slightly wider, 54-degree V. There are no shortage of 60-plus-degree V-twins out there, but the geometry just doesn't look right to someone used to Harley engines, and it affects the overall look of the bike. Suzuki gets credit for closing the angle just a little bit for a more natural-looking engine to Western eyes.Inspections of certain systems and components are required at 2,500 mile (4,000 km) intervals. See Owner’s Manual for full details. An estimated 35,000–40,000 people were killed outright by the bombing at Nagasaki. A total of 60,000–80,000 fatalities resulted, including from long-term health effects, the strongest of which was leukemia with an attributable risk of 46% for bomb victims. [55] Others died later from related blast and burn injuries, and hundreds more from radiation illnesses from exposure to the bomb's initial radiation. [56] Most of the direct deaths and injuries were among munitions or industrial workers. [57]

Fat Boys have a redesigned softail frame with Showa front and rear suspension and new twin-counterbalanced Milwaukee-Eight engines. The two 2018 variants comprise: Low and wide have always been the hallmarks of the Fat Boy line, and the newest additions to the family take it down even further. Unladen seat height on the base Fat Boy drops from 27.2 inches to 26.4 inches, while the Lo drops from 26.4 inches on down to an even 26 inches between the '15 and '16 models, respectively, though the Lo wasn't carried forward to 2017. The “S” starts out life already slammed down to 26 inches with only 4.7 inches of ground clearance, right on par with the Lo. Oppenheimer reviewed his options in early 1943 and gave priority to the gun-type weapon, [2] but he created the E-5 Group at the Los Alamos Laboratory under Seth Neddermeyer to investigate implosion as a hedge against the threat of pre-detonation. Implosion-type bombs were determined to be significantly more efficient in terms of explosive yield per unit mass of fissile material in the bomb, because compressed fissile materials react more rapidly and therefore more completely. Nonetheless, it was decided that the plutonium gun would receive the bulk of the research effort, since it was the project with the least uncertainty involved. It was assumed that the uranium gun-type bomb could be easily adapted from it. [5] Naming Campbell, Richard H. (2005).

To allow any rider to make a personal statement, Harley-Davidson offers a wide variety of motorcycle styles within the Cruiser segment, from nostalgic to very modern. A cruiser rider seeks to disconnect from an increasingly hectic life, and only the world’s most desirable motorcycle company can offer these riders so many ways to reach that goal. Authentic heritage meets modern technology for power, style, and the unadulterated riding experience – around town or along country roads. For 2022 new paint colors are offered across the Cruiser model line-up.
