13 - Arado Ar 234 B-2

Arado Ar234 B-2 in Norway

The Luftwaffe's super reconnaissance aircraft

by Bjørn Jacobsen

The 234 was the WWII equivalent to the Cold War’s U-2.

It flew faster and higher than any allied aircraft and was the world's first operational jet powered reconnaissance and bomber. With a speed of 742 km/h (461m.p.h) and operating altitude of over 30.000ft, not one of the allied planes could overtake the Arado.

 

Ar 234 was actually the only aircraft that could operate over allied territory in 1944-1945 - and get safely home again.

 

The Ar 234 began its career as reconnaissance aircraft as early as under the D-Day in 1944, while the corresponding allied aircraft were only on the drawing board.

 

Arado 234 in Norway

It was in January 1945 that FAGr.5 (FernAufklärungsGruppe 5) moved to Sola (Norway), equipped with three Ar 234B-2b.

 

The mission was reconnaissance support for German submarines off Scapa Flow.

The squadron was named Einsatzkommando 1./FAGr.1

 

The squadron flew reconnaissance missions over Scotland and England and RAF Spitfire was sent up to intercept the planes, but none had any chance to get near the Arados

 

As a bomber, the Arado 234 was most of all used by the KG 76 (but also other Geschwaders had the Ar 234). All these units were based in Germany.

 

Early in the morning 5th May 1945, most of the Arado 234 in Germany took to the skies and flew to their sister squadron in Norway.

 

Not all arrived: Some returned to Germany with engine trouble and one crashed in the North Sea - but when the Allied Forces arrived at Sola on Sunday the 10th May, ten Ar 234B-2 was parked at the airport, to the delight of the British and American Air Forces!

Above: This is one of the few pictures of the Ar 234B-2 aircraft at Sola/Forus in summer 1945.

The two planes to the left belong to KG 76 and came to Sola on the 5th May.

Note that the aircraft to the left still have winter camouflage.

The third plane from the left is from 1 (F) / 33

The plane far to the right is the "Norwegian" 9V+BH

Note also that the rudders are removed to prevent unauthorized use.

 

 

I am going to build the “Norwegian” Ar 234B-2b (9V+BH) W.Nr 140493

of Eins.kdo 1./FAGr.1 as it appeared on Sola

when the war ended on May the 8th 1945

 

The Cockpit

The first thing to build is the

cockpit.

 

The cockpit in the Ar 234B-2 differs from most other cockpits during this period.

 

Although several of German bombers had Plexiglas noses, they were not at all similar to the cockpit in Ar 234

 

In Ar 234B-2 the pilot sat alone in

the very front of the nose, with

instruments on all sides.

 

When you see pictures from the

cockpit, you will almost think that

this is a modern spacecraft (!)

not a WWII plane.

 

The interior of the cockpit is painted

with RLM 66 (SchwartzGrau).

 

With help from Photo Etched

parts from Eduard, the cockpit is

almost finished

 

Some of the instruments

in the cockpit roof is

waiting to be placed,

but altogether, it is

beginning to look like

a 234-cockpit.

 

The entrance to the

cockpit was through a

Plexiglas hatch in the

top of the canopy.

Through the hatch,the pilot dropped straight down into the seat.

 

The seat was an "ejection seat", which was a revolutionary new

invention. No Allied aircraft had something similar.

 

 

 

The Cameras

All the Ar 234B-2 belonging to

Eins.kdo 1./FAGr.1 at Sola was

unarmed reconnaissance aircraft.

 

That the aircraft had no armament

was of little concern to the pilots.

 

No Allied aircraft were able to

engage them anyway.

 

The aircraft had two big Carl Zeiss

ReihenBild cameras.

There was no zoom on the

cameras, so they used two

cameras with different focal lengths.

 

The negatives were 30x30cm

and each camera could take

up to120m film. The cameras were placed in the rear part of the fuselage

 

The aerial photographs they took over Britain were reported to be of

great value to Germany

Wheels and wheel wells

The wings on Ar 234 was so thin that they did not gave room for the

landing gear and main wheels

 

The wings were placed so high on the fuselage that a landing gear would be very long and have problems being folded.

 

The landing gear had to be placed somewhere else and the fuselage was the obvious solution.

 

The problem was that the wings also had no space for fuel. Fuel had therefore to be placed in the fuselage and since the RLM (the German

Aviation Ministry) demanded fuel for at least 2.000 km (1.240 miles),

there was so much fuel in the fuselage – and no room for the main wheels.

 

The result was that the first prototypes had no wheels at all.

The aircraft started on a sled and landed on skids under the belly and

under the engines

 

This was no good solution, and after hard work, the aircraft constructors

managed to place two large low-pressure tires in the fuselage

 

Each wheel well had two doors, one of which was only opened when

the wheels were pulled in or out of the fuselage

 

For a model builder, this makes it difficult to position the landing gear in

the small

opening that is

left when the

main door is

closed.

 

Landing gear

and wheel wells

are painted with

RLM 02

 

 

 

Fuselage Assembly

The cockpit, the wheel wells, the cameras are in place and the extra weight is glued behind the cockpit

to prevent the aircraft to be a tail sitter.

Then the fuselages are glued together..

That means putty and sanding. Both the cockpit section and the fuselage needed adjustments and fillings to be fine.

I used the following After Markets products when building the Arado Ar 234

 

Photo Etched parts from Eduard

 

Wheel bay and cockpit set from Aires

 

Etched parts, fuel box, wing flaps, wheels and parachute bay from CMK/Czech Master Kits

 

Canopy from Squadron

 

Landing Gear from Scale Aircraft Conversions

 

 

 

The Cockpit Section

The cockpit section is now in place.

What is lacking is some paint and the

open hatch on top of the canopy.

The hatch will be glued om at the very

end when everything else is done.

The picture to the right is of an

Ar 234B-2 which is restored in the U.S.

 

This aircraft was one of KG76 aircraft

that the Americans took from Sola in

summer 1945

 

 

 

 

The Wings

I have cut out the flaps so they can later be fixed in the lowered position.

I use the wing flaps from CMK/Czech Master Kits

 

Then of course, a some putty and sanding is necessary before the wings

look way I want

 

 

 

 

Priming and Painting

According to the best Arado specialist in Norway, Frithjof Ruud, the

Americans have used the “wrong” colors when they restored the

aircraft (see picture above)

 

I am therefore going to use the colors which actually were used on the

aircraft in 1945.

 

The machine had a splinter camouflage of RLM71 (Dunkel Grü / Dark

Green) and RLM70 (Schwartzgrün / Black Green) with RLM65

(Hell Blau / Light Blue) on

the underside.

 

For RLM71, I used Vallejo

Olive Grey and for the

RLM70 I used Vallejo

Black Green.

The color which I find

closest to the RLM65 was

AKAN Hellblau.

 

The colors was lightened

to a 1:48 version

 

The paint on the Ar 234

was much brighter than

on other German aircraft.

 

It was important to reduce

drag as much as possible

on these super-fast planes.

 

Therefore, they used a

special plastic filler to

cover all the rivets and

panel joints on the fuselage.

 

The hull was then

polished to a very smooth

and glossy surface.

 

 

 

 

 

Wheels and Engines

The wheels and landing gear are put in place and 9V+BH is finally standing on its own.

 

The next step is to attach the Junkers Jumo 004B-1 turbojet engines to the wings.

 

When the engines are in place and the cockpit hatch is fitted and the plane presents itself as the extremely effective and innovative jet from 1945
