She was a huge aircraft, as well she would have to be to meet the requirements.
She has six massive pusher piston engines mounted on a wing that spanned 230 feet. To this day this is the largest wingspan of any mass produced combat aircraft in history. The massive wing was seven and one-half feet thick and had a service pathway to the piston engines internally that allowed the engines to be worked on by the crew while in flight. The aircraft dwarfed the B-29 Super fortress which was the largest World War II bomber aircraft and which had delivered the nuclear bombs to Hiroshima and Nagasaki that ended World War II.
Initially, the cockpit was designed similar to the B-29, being flush to the cigar shaped fuselage.. Here is a picture of a B-29 compared to the initial B-36:
After World war II, relations with the USSR soured rapidly. Even though the US and her allies had worked together with the USSR to defeat Nazi Germany, the USSR itself developed into another brutal dictatorship that had visions itself of fomenting communist revolution throughout the world and ultimately controlling the world. Once the USSR developed nuclear weapons of its own, the need for the B-36 became paramount. Now, the massive weapons load, the tremendous range, and the relative high speed and high altitude of the B-36 became the natural tool to deter the Soviet Union.
The United States formed the US Air Force as a separate, independent service branch in 1947 and all B-36 bombers were immediately transferred to the USAF. Modifications were made to make the aircraft suitable for the new task of deterring the USSR. Her cockpit was redesigned and placed atop the fuselage. She got more powerful engines. In her new role of strategic deterrence, she became operational in 1949 and more orders were placed with production runs that would continue through 1954.
The confrontation between the US and her allies (The West) and the USSR and her allies (The East) was named the "Cold War," after the Berlin airlift of 1948, and particularly after the Soviet Union's first successful nuclear bomb detonation in 1949. The B-36 was the only American aircraft with the range and payload to carry all of the United States nuclear inventory from airfields on American soil to targets in the USSR. In order to carry the largest US nuclear weapons, the bomb bays had to be combined and the modification to allow this was called the "Grand Slam Installation."
Soon, B-36 bombers were available in numbers and operating from US air baises in the United States and from air bases of allies in Europe and the Western Pacific.
Despite its capabilities, the B-36 was designed in the era of piston engines driving propellers. In the late 1940s and throughout the 1950s, the jet age was ushered in. The "jet age" actually started towards the end of World War II when the Nazis introduced the first production jet fighter, the Me-262 twin engine fighter. But it began in earnest at the end of the 1940s and into the 1950s. In order to increase speed and range, the B-36 underwent a transformation that brought it into the jet age. In addition to its six massive piston engines, four jet engines were added. These were house outboard of the piston engines in a single nacelle on each wing which housed two of the jet engines.
Because of its unique nature with so many piston and jet engines, the crews of the B-36 often indicated that the had, "Six tuning and four burning."
Despite this, as time progressed in the 1950s, the B-36 was rapidly becoming obsolete. It was too slow and as time went on, was simply not capable of penetrating growing Soviet defenses with the high degree of success required for its nuclear delivery requirements. However, it's first jet rival, the Boeing B-47 Stratojet, which became fully operational in 1953, lacked the range to attack the Soviet homeland from North America without aerial refueling and could not carry the huge first-generation Mark 16 hydrogen bomb.
So, the B-36 served on, and General Curtis Lemay, the head of the US Air Force Strategic Air Command, kept the B-36 force, through intense training and development, an effective force to deliver nuclear weapons. During this time, the B-36 was the heart of the Strategic Air Command force. Its maximum payload was greater than any other bomber in the US inventory, including the newly developed B-52 which entered service in 1955.
Although the B-36 was slow and could not refuel in midair, she could fly missions to intercontinental targets and stay aloft for up to 40 hours at a time. In addition, through the mid and late 1950s, the B-36 maintained a phenomenal cruising altitude which made it possible for her to fly above the capabilities of most Soviet interceptors of the day, as well as their ground-based anti aircraft guns.
Nonetheless, the introduction of the B-52 in 1955 changed everything. This was clearly the aircraft that would replace the B-36. The B-52 was faster, it could fly as high and higher, and it could be refueled in mid-air giving it essentially unlimited range. Through the late 1950s the B-52 fleet grew, supplanting the B-36, and in 1959, the last B-36 strategic bomber aircraft were retired.
In addition, supersonic intercontinental bombers were being developed, including the Mach 2 B-58 hustler, which went into service in the 1960s, and the even faster, higher flying and very exotic B-70 Valkyrie, which was cancelled.
With the advent of Intercontinental Ballistic Missiles (ICBMs) beginning in the 1960s, aircraft like the B-36 were rendered completely, irrevocably obsolete. The newer, faster jet bombers served on due to America's desire to maintain a triad of nuclear deliver options, but the B-36 had seen its day.

Jimmy Stewart Military service (including the B-36)
I have had this model for some time but did not intend to build it for a couple of more years. However, over the Thanksgiving break this year, I once again watched the old movie, "Strategic Air Command," starring Jimmy Stewart. The movie features the B-36 heavily and I was moved to go ahead and move up the B-36 in my build queue. I am writing this part of my model review as a tribute to Jimmy Stewart.
Many people do not know it, but in addition to Jimmy Stewart being one of my favorite all time movie stars, he was also a great American patriot and military hero.
Though already a very successful movie star when World War II broke out, he was also a very successful aircraft racer. It was one of his hobbies and he was very good at it, winning numerous races, medals, and honors in the late 1930s.
But he came from a patriotic family, where his grandfathers and father had served in the US military. So when it became apparent to him that war was inevitable, he went down and enlisted in the US Army in March 1941, over eight months before Pearl Harbor. He did not ask for any favors though he had a college degree, was 33 years old and was very well known. No, Jimmy Stewart enlisted as a simple private.

When it was learned that he had significant flying experience, in addition to a college degree, he was transferred to the Army Air Corps. At 33 years of age, he was already six years older than the maximum age for new pilot recruits, but because the need was great, and because of his experience, this requirement was waived and he was inducted as a pilot. He was commissioned a Lt. in the USAAC in January 1942, one month after Pearl Harbor.
He wanted to go fight, but because of his age and notoriety, he remained state side, training others. In that role he was steadily promoted through Captain and to Major. But he continued to put in for combat duty, and finally, in 1943 it was granted.
He was transferred to England in command of the 703rd Bomber Squadron, flying B-24 Liberator bombers against Germany. while flying for the 703rd, he earned the Distinguished Flying Cross for his efforts
leading major bomber raids against the heavily defended 3rd Reich. He was promoted to the Operations Officer for the entire 453rd Bomber Group and continued flying combat missions.
