End of WWII
a diorama by Bjørn Jacobsen
August 6: Hiroshima bomb dropped.
August 8: Soviet Union declares war on Japan and invades Manchuria.
August 9: Nagasaki bomb dropped.
August 10: Emperor Hirohito breaks the cabinet deadlock and decides that Japan must surrender.
August 14: Japan agreed to unconditional surrender
August 15: Emperor Hirohito announced the surrender in a radio broadcast.
September 2: Japan formally surrender in Tokyo Bay aboard the USS Missouri
This diorama was initially a Group Build with the title “End of WWII”. I felt this was an interesting task and soon realise that the atomic explosion over Hiroshima was (at least in my opinion) the one single incident that represent the end of this global war.
I have tried to make a diorama to commemorate this terrible event.
The Boeing B-29 Superfortress
The big four engine Boeing B-29 Superfortress
was one of the most complicated and expensive
airplane produced by the United States during
World War II.
The first B-29 was delivered to USAAF in May
1944 and nearly 4.000 were built before the plane
was retired in 1960.
In WWII, the B-29 was used in the Pacific theatre
as a high-altitude strategic bomber, but the B-29
also excelled in low-altitude night time incendiary
It was very advanced for its time and featured a
pressurized cabin, all dual wheeled, tricycle landing gears, and a remote, electronic fire-control system that controlled four machine gun turrets. A manned tail gun installation was semi-remote.
The B-29 had a crew of eleven.
It had a length 99 ft. (30.18 m), a wingspan of 141 ft 3 in (43.06 m) and a range of 3.250 mi (5.230km), the ferry range was 5,600 mi (9,000 km) and had 10 × .50 in (12.7 mm) Browning M2/ANs in remote-controlled turrets and the standard bomb load was 20,000 lb (9,000 kg)
One of the B-29's final roles in World War II was carrying out the atomic bomb attacks on Hiroshima and Nagasaki.
The B-29, which dropped the atomic bomb over
Hiroshima August 6 1945, became World War II's
most famous airplane.
The bomber was one of 15 B-29s with the
"Silverplate" modifications necessary to deliver
atomic weapons. These modifications included
an extensively modified bomb bay with pneumatic
doors and British bomb attachment and release
systems, reversible pitch propellers that gave
more braking power on landing, improved engines
with fuel injection and better cooling, and the
removal of protective armour and gun turrets.
The pilot of the atomic bomb mission, Col. Paul
Tibbets, named the plane “Enola Gay” after his
The decision to drop the bomb was a difficult one
for the new President Harry S. Truman.
That single blast from the bomb – codenamed
“Little Boy” was the equivalent of 16.000 tons of
T.N.T. The force of the blast had the potential to
shorten the war and reduce the number of
American and Japanese causalities.
But that single blast also had the potential to kill
hundreds of thousands Japanese civilians.
Truman decided to go ahead and Col. Tibbets
and the crew of Enola Gay dropped the first
atomic bomb, which exploded 2,000 feet (600m)
above Hiroshima, destroying five square miles
of the city and killing 80,000 people immediately.
The final death toll was calculated at 135,000.
Hiroshima was chosen because it had not been
targeted during the US Air Force's conventional
bombing raids on Japan, and was therefore
regarded as being a suitable place to test the
effects of an atomic bomb.
It was also an important military base.
The Allies feared that any conventional attempt to
invade the Japanese home islands would result
in enormous casualties, and the bomb was seen
as a way of bringing the war against Japan to a
In addition, it may also have been a way of
demonstrating American military superiority over
the Soviet Union.
However, Hiroshima’s devastation failed to elicit
immediate Japanese surrender and three days later, on August 9 Major Charles Sweeney flew another
B-29 bomber with a plutonium bomb, even more powerful than the one used at Hiroshima. The bomb weighed nearly 10,000 pounds and produced a 22-kiloton blast.
The target was the city of Kokura, but thick clouds over Kokura, drove Sweeney to the secondary
The topography of Nagasaki, which was nestled in narrow valleys between mountains, reduced the bomb’s effect, but still about 40,000 people were killed instantly and a third of the city was destroyed. The final death toll was calculated as at least 50,000.
The day after the Nagasaki bombing Emperor Hirohito breaks the cabinet deadlock and decides that Japan must surrender. On the 14th of August, Japan agreed to the Allies' terms of surrender and on August 15, 1945, the Japanese Emperor announced his country’s surrender in a radio broadcast.
It brought six years of a global conflict to an end. A war that had accounted for the death of more than 60 million people.
The World War II was over at last
Boeing B-29 Enola Gay on Tinian in the Marianas Islands. The 509th’s distinctive tail code of an arrow inside a circle was changed to that of the 6th Bomb Group’s “circle R” by Tibbets after Tokyo Rose noted the tail codes of the newly-arrived aircraft in two separate radio broadcasts.
“Little Boy” exploded with the energy equivalent of 16,000 tons of TNT
The enormous devastation of the city of Hiroshima
The B-29 model of
The model is a 1/72 from Academy,
which was the only one I found of
the Enola Gay.
It is almost completely impossible to
see inside the fuselage when the
fuselages are glued together and I
therefore choose not to put any
energy in doing a nice interior.
It was quite obvious that the model
would be a “tail sitter” if not weighted
heavily in the front.
The kit consists of very few parts
and was very easy to put together.
The propeller shafts were easy to
lubricate and would hopefully spin
when I blow at them.
The plane was all in aluminium, so
the painting was easy enough,
except that it needed some patches
with different aluminium colours to
appear as the original plane.

"Enola Gay" is displayed at NASM's
Steven F. Udvar-Hazy Cente in
There is therefore no lack of pictures
and videos of this plane.
It would be impossible to recreate
the actual atomic explosion in a
diorama, and I therefore had to
make a painting of the explosion
and photograph the Enola Gay in
front of the painting (which was
mostly done on the computer)
Here are my pictures of "Enola Gay" and the "End of WWII":

Take-Off with the first atomic bomb in the belly. (The spinning propellers are achieved by blowing at them with a vent)

The atomic explosion over Hiroshima.
The bomb was dropped from 31,060 feet (9,470 m) and detonated at 2.000 feet (600m).
Of course, it would be impossible to make a diorama with the actual dimensions. I therefore have placed the B-29 far too low in the picture above, but this is the only way to capture the plane, the explosion and the city in the same picture.
The picture below is perhaps a little more realistic.
