Over 4,700 B-17 Bombers Were Lost During World War II

Of the over 12,700 B-17 Flying Fortress bombers produced from 1935-1945, approximately 4,735 were lost in combat operations over Europe. That staggering number provides a sense of just how dangerous the air war over Germany was for the American bomber crews. On some of the costliest missions, over 20% of the bombers were shot down. Read on for the full story behind the B-17, its achievements and sacrifices during World War II, and how many of these iconic planes were ultimately lost.

Built for Precision Bombing

The Boeing B-17 was the first mass-produced, four-engine heavy bomber. It represented American faith in the concept of long-range strategic bombing campaigns against enemy industrial and military targets. The B-17 had a typical crew of 10 and was armed with up to 13 .50 caliber machine guns for defense. It could carry a bomb load of up to 6,000 pounds internally plus more on external racks.

When fully loaded with fuel and bombs, the B-17 could weigh over 60,000 pounds. Yet it had a maximum speed of 287 mph and a range of 2,000 miles. Those capabilities enabled the precision bombing of targets deep inside Germany.

Staggering Losses Over Europe

However, those bombing missions came at a horrific cost. B-17 squadrons suffered loss rates averaging 25% in 1943. Some raids lost 60 out of 300 planes – a 20% loss rate for a single mission.

Why were losses so high? Attacking heavily defended targets without fighter escorts left the B-17s extremely vulnerable. Losses peaked in October 1943 during the Schweinfurt-Regensburg raids:

Schweinfurt Mission, October 14, 1943

• 291 B-17s attacked the ball bearing factories at Schweinfurt
• 77 B-17s shot down (26% loss rate)
• 122 damaged
• 650 crew members killed or captured

Second Schweinfurt Raid, October 14, 1943

• 376 B-17s dispatched
• 60 B-17s shot down (16% loss rate)
• 138 damaged
• 600 crew members killed or captured

These loss rates were unsustainable. New tactics were clearly needed.

Improved Tactics and Survivability

By 1944, improved fighter escorts helped reduce loss rates to around 5%. New tactics like tighter bomber formations suppressed individual losses. The sheer determination of B-17 crews also took a toll on German defenders.

The B-17 itself was built for survivability. It could absorb extensive damage and keep flying. Stories abound of B-17s limping back to England with gaping holes, missing parts, and multiple dead engines. While certainly not indestructible, the B-17‘s toughness helped compensate for lack of escorts early on.

By the Numbers: B-17 Losses and Production

The heavy cumulative losses resulted from flying endless missions against heavily defended targets. Some key B-17 loss statistics:

• 12,732 B-17s produced between 1935-1945
• 4,735 B-17s lost in combat in Europe
• Over 1,200 destroyed in non-combat flying accidents
• More than 6,000 scrapped after the war

At the height of production in 1944, Boeing‘s Seattle plant built 16 B-17s per day. Those numbers were needed to sustain forces as more planes and crews were lost.

The Human Toll

For bomber crews, the odds of survival were dismal:

• A crew member had only a 25% chance of surviving 25 missions
• Over 26,000 airmen were killed in the European theater
• 28,000 became POWs after being shot down
• Thousands suffered debilitating physical and psychological trauma

B-17 combat losses exceeded those of any other U.S. aircraft in World War II. The sheer sacrifice of lives lost gives the cold statistics real meaning. Behind each number was a crew of 10 young men on a dangerous mission to defeat Nazi tyranny.

Restored Relics

Given the catastrophic losses, it is amazing that any B-17s survived the war intact. Out of over 12,700 built, around 45 exist today in complete form. Of those, fewer than 10 remain airworthy.

Restored B-17s now reside in museums and are highlights of air shows. In 2019, the B-17 nicknamed "Sentimental Journey" was offered for sale by the Commemorative Air Force. This iconic plane fetched an impressive $4.8 million at auction.

These renewed relics ensure future generations learn about and appreciate the B-17‘s role in securing victory in Europe. Their value also stems from honoring the memory of those who perished flying missions aboard them.

The Courage to Carry On

The sheer determination of B-17 crews in the face of devastating losses is inspiring. They believed deeply in their cause and duty. Families back home dreaded the sight of a Western Union telegram notifying them a loved one was lost. Yet new recruits continued signing up, as veterans kept flying mission after mission.

Some highly decorated veterans flew 50+ sorties. Colonel Frank Kurtz completed 50 missions as a B-17 pilot and had this to say:

"Looking back, I marvel at our audacity. War makes you do things you probably shouldn‘t do, but you do them anyway."

That spirit encapsulated the bravery and sacrifice of the men who flew the B-17. They put their lives on the line repeatedly to accomplish what needed to be done. The staggering cost will never be forgotten.

Over 4,700 B-17s and their crews were lost during World War II. But their sacrifice was not in vain, as they helped ensure victory over Nazi oppression. That is the lasting legacy of the B-17 and the brave men who flew her.
