A B-17 Flying Fortress releases bombs over the Focke-Wulf factory during the first major U.S. daylight raid deep into Germany.

On October 9, 1943, B-17 Flying Fortress bombers of the 303rd Bombardment Group (USAAF) carried out one of the most daring missions of the air war over Europe — a deep strategic bombing raid on the Focke-Wulf aircraft factory in Marienburg, Germany.

It was the first major American daylight bombing attack deep inside German territory, marking a turning point in the Allied air offensive against the Third Reich.

The Target: Focke-Wulf Aircraft Works:

The factory at Marienburg (today Malbork, Poland) was a key production center for Focke-Wulf aircraft, including fighters used by the Luftwaffe on multiple fronts.

Destroying this facility meant:

• Disrupting German aircraft production

• Weakening Luftwaffe fighter strength

• Forcing Germany to divert resources to air defense

The target was heavily defended and far beyond the range of continuous Allied fighter escort.

The B-17 Flying Fortress:

The B-17 was the backbone of the U.S. strategic bombing campaign:

• Four-engine heavy bomber

• Heavy defensive armament

• High-altitude precision bombing doctrine

Despite its nickname, the Flying Fortress was not invulnerable, especially when operating without long-range fighter cover.

The Mission and the Bombing Run:

During the attack:

• B-17s dropped heavy high-explosive bombs on the factory complex

• Bombs were released from high altitude under intense anti-aircraft fire

• The bombing caused significant damage to production facilities

The photograph captures the exact moment when bombs fall from the aircraft — a visual record of industrial warfare from the air.

German Fighter Interception:

On the return flight, the bomber formations were:

• Intercepted by Luftwaffe fighters

• Attacked repeatedly without escort protection

• Forced into defensive box formations

American losses were severe:

• Approximately 80 bombers were lost

• Hundreds of aircrew were killed or captured

The mission demonstrated both the reach and the cost of daylight strategic bombing.

Strategic Importance of the Raid:

Despite heavy losses, the Marienburg raid proved that:

• The USAAF could strike deep inside Germany

• German industrial centers were vulnerable

• Strategic bombing would become a central tool of Allied victory

Lessons learned from this mission accelerated the deployment of long-range escort fighters, such as the P-51 Mustang.

The Human Cost of Strategic Bombing:

Behind the statistics were:

• Young bomber crews flying into extreme danger

• Civilians working in industrial zones

• Entire cities exposed to total war from the air

Strategic bombing blurred the line between battlefield and home front.

Historical Significance:

This raid stands as:

• A milestone in the Allied air campaign

• A demonstration of both courage and sacrifice

• A reminder of the brutal economics of industrial warfare

It was not just an attack on a factory — it was an attack on Germany’s ability to continue the war.
