Now for the History of WWII Statistics.

276,000 aircraft were manufactured in the U.S.
43,000 planes lost overseas, including 23,000 in combat.
14,000 lost in the continental U.S. 

The U.S. civilian population maintained a dedicated effort for four years, many working long hours seven days per week and often also volunteering for other work.  WWII was the largest human effort in history.
Statistics are from Flight Journal magazine.

THE PRICE OF VICTORY (cost of an aircraft in WWII dollars)
B-17 $204,370.        P-40 $44,892.
B-24 $215,516.        P-47 $85,578.
B-25 $142,194.        P-51 $51,572.
B-26 $192,426.        C-47 $88,574.
B-29 $605,360.        PT-17 $15,052.
P-38 $97,147.          AT-6 $22,952.

PLANES A DAY WORLDWIDE
From Germany’s invasion of Poland 1 Sept, 1939 and ending with Japan’s surrender 2 Sept, 1945 — 2,433 days
From 1942 onward, America averaged 170 planes lost a day.

How many is a 1,000 planes?  B-17 production (12,731) wingtip to wingtip would extend 250 miles.  1,000 B-17s carried 2.5 million gallons of high octane fuel and required 10,000 airmen to fly and fight them.

THE NUMBERS GAME
9.7 billion gallons of gasoline consumed, 1942-1945.
107.8 million hours flown, 1943-1945.
459.7 billion rounds of aircraft ammo fired overseas, 1942-1945.
7.9 million bombs dropped overseas, 1943-1945.
2.3 million combat sorties, 1941-1945 (one sortie = one takeoff).
299,230 aircraft accepted, 1940-1945.
808,471 aircraft engines accepted, 1940-1945.
799,972 propellers accepted, 1940-1945.

According to the AAF Statistical Digest, in less than four years (December 1941- August 1945), the US Army Air Forces lost 14,903 pilots, aircrew and assorted personnel plus 13,873 airplanes — inside the continental United StatesThey were the result of 52,651 aircraft accidents (6,039 involving fatalities) in 45 months.

Think about those numbers.  They average 1,170 aircraft accidents per month — nearly 40 a day. (Less than one accident in four resulted in totaled aircraft, however.)

It gets worse…..
Almost 1,000 Army planes disappeared enroute from the US to foreign climes.  But an eye-watering 43,581 aircraft were lost overseas including 22,948 on combat missions (18,418 against the Western Axis) and 20,633 attributed to non-combat causes overseas.

In a single 376 plane raid in August 1943, 60 B-17s were shot down.  That was a 16 percent loss rate and meant 600 empty bunks in England.  In 1942-43 it was statistically impossible for bomber crews to complete a 25-mission tour in Europe.

Pacific theatre losses were far less (4,530 in combat) owing to smaller forces committed.  The worst B-29 mission, against Tokyo on May 25, 1945, cost 26 Superfortresses, 5.6 percent of the 464 dispatched from the Marianas.
On an average, 6,600 American servicemen died per month during WWII, about 220 a day.  By the end of the war, over 40,000 airmen were killed in combat theatres and another 18,000 wounded.  Some 12,000 missing men were declared dead, including a number “liberated” by the Soviets but never returned.  More than 41,000 were captured, half of the 5,400 held by the Japanese died in captivity, compared with one-tenth in German hands.  Total combat casualties were pegged at 121,867.

U.S. manpower made up the deficit.  The AAF’s peak strength was reached in 1944 with 2,372,000 personnel, nearly twice the previous year’s figure.

The losses were huge—but so were production totals.  From 1941 through 1945, American industry delivered more than 276,000 military aircraft.  That number was enough not only for U.S. Army, Navy and Marine Corps, but for allies as diverse as Britain, Australia, China and Russia.  In fact, from 1943 onward, America produced more planes than Britain and Russia combined.  And more than Germany and Japan together 1941-45.

However, our enemies took massive losses.  Through much of 1944, the Luftwaffe sustained uncontrolled hemorrhaging, reaching 25 percent of aircrews and 40 planes a month.  In late 1944 into 1945, nearly half the pilots in Japanese squadrons had flown fewer than 200 hours.  The disparity of two years before had been completely reversed. 

Experience Level:
Uncle Sam sent many of his sons to war with absolute minimums of training.  Some fighter pilots entered combat in 1942 with less than one hour in their assigned aircraft.

The 357th Fighter Group (often known as The Yoxford Boys) went to England in late 1943 having trained on P-39s.  The group never saw a Mustang until shortly before its first combat mission.

A high-time P-51 pilot had 30 hours in type.  Many had fewer than five hours.Some had one hour.

With arrival of new aircraft, many combat units transitioned in combat.  The attitude was,”They all have a stick and a throttle.  Go fly `em.” When the famed 4th Fighter Group converted from P-47s to P-51s in February 1944, there was no time to stand down for an orderly transition.  The Group commander, Col. Donald Blakeslee, said, “You can learn to fly `51s on the way to the target. 

A future P-47 ace said, “I was sent to England to die.”  He was not alone.  Some fighter pilots tucked their wheels in the well on their first combat mission with one previous flight in the aircraft.  Meanwhile, many bomber crews were still learning their trade: of Jimmy Doolittle’s 15 pilots on the April 1942 Tokyo raid, only five had won their wings before 1941.  All but one of the 16 copilots were less than a year out of flight school.

In WWII flying safety took a back seat to combat.  The AAF’s worst accident rate was recorded by the A-36 Invader version of the P-51: a staggering 274 accidents per 100,000 flying hours.  Next worst were the P-39 at 245, the P-40 at 188, and the P-38 at 139.  All were Allison powered.

Bomber wrecks were fewer but more expensive.  The B-17 and B-24 averaged 30 and 35 accidents per 100,000 flight hours, respectively– a horrific figure considering that from 1980 to 2000 the Air Force’s major mishap rate was less than 2.

The B-29 was even worse at 40; the world’s most sophisticated, most capable and most expensive bomber was too urgently needed to stand down for mere safety reasons.  The AAF set a reasonably high standard for B-29 pilots, but the desired figures were seldom attained.  The original cadre of the 58th Bomb Wing was to have 400 hours of multi-engine time, but there were not enough experienced pilots to meet the criterion.  Only ten percent had overseas experience. Conversely, when a $2.1 billion B-2 crashed in 2008, the Air Force initiated a two-month “safety pause” rather than declare a “stand down,” let alone grounding.

The B-29 was no better for maintenance.  Though the R3350 was known as a complicated, troublesome power-plant, no more than half the mechanics had previous experience with the Duplex Cyclone.  But they made it work.

Navigators:
Perhaps the greatest unsung success story of AAF training was Navigators.  The Army graduated some 50,000 during the War.  Many had never flown out of sight of land before leaving “Uncle Sugar” for a war zone.  Yet the huge majority found their way across oceans and continents without getting lost or running out of fuel — a stirring tribute to the AAF’s educational establishments.

Cadet To Colonel:
It was possible for a flying cadet at the time of Pearl Harbor to finish the war with eagles on his shoulders.  That was the record of John D. Landers, a 21-year-old Texan, who was commissioned a second lieutenant on December 12, 1941.  He joined his combat squadron with 209 hours total flight time, including 20 in P-40s.  He finished the war as a full colonel, commanding an 8th Air Force Group — at age 24.

As the training pipeline filled up, however those low figures became exceptions.  By early 1944, the average AAF fighter pilot entering combat had logged at least 450 hours, usually including 250 hours in training.  At the same time, many captains and first lieutenants claimed over 600 hours.

FACT:
At its height in mid-1944, the Army Air Forces had 2.6 million people and nearly 80,000 aircraft of all types.  Today the US Air Force employs 327,000 active personnel (plus 170,000 civilians) with 5,500+ manned and perhaps 200 unmanned aircraft.  The 2009 figures represent about 12 percent of the manpower and 7 percent of the airplanes of the WWII peak.

IN SUMMATION:
Whether there will ever be another war like that experienced in 1940-45 is doubtful, as fighters and bombers have given way to helicopters and remotely-controlled drones over Afghanistan and Iraq.  But within living memory, men left the earth in 1,000-plane formations and fought major battles five miles high, leaving a legacy that remains timeless.

This is an excellent summary of the effort required in WWII.  It focuses on the American side of things, but the British, Germans and Japanese expended comparable energy and experienced similar costs.  Just one example for the Luftwaffe; about 1/3 of the Bf109s built were lost in non-combat crashes.  After Midway, the Japanese experience level declined markedly, with the loss of so many higher-time naval pilots. 

WW II Trivia:

You might enjoy this from Col D. G. Swinford, USMC, Ret and history buff. You would really have to dig deep to get this kind of ringside seat to history:1. The first German serviceman killed in WW II was killed by the Japanese (China, 1937), the first American serviceman killed was killed by the Russians (Finland 1940); highest ranking American killed was Lt Gen Lesley McNair, killed by the US Army Air Corps. So much for allies.

2. The youngest US serviceman was 12 year old Calvin Graham, USN. He was wounded and given a Dishonorable Discharge for lying about his age. His benefits were later restored by act of Congress.

3. At the time of Pearl Harbor, the top US Navy command was called CINCUS (pronounced ‘sink us’), the shoulder patch of the US Army’s 45th Infantry division was the Swastika, and Hitler’s private train was named ‘Amerika.’ All three were soon changed for PR purposes.

4. More US servicemen died in the Air Corps than the Marine Corps. While completing the required 30 missions, your chance of being killed was 71%.

5. Generally speaking, there was no such thing as an average fighter pilot. You were either an ace or a target.  For instance, Japanese Ace Hiroyoshi Nishizawa shot down over 80 planes.  He died while a passenger on a cargo plane.

6. It was a common practice on fighter planes to load every 5th round with a tracer round to aid in aiming. This was a mistake. Tracers had different ballistics so (at long range) if your tracers were hitting the target 80% of your rounds were missing.  Worse yet tracers instantly told your enemy he was under fire and from which direction. Worst of all was the practice of loading a string of tracers at the end of the belt to tell you that you were out of ammo. This was definitely not something you wanted to tell the enemy. Units that stopped using tracers saw their success rate nearly double and their loss rate go down.

YOU’VE GOT TO LOVE THIS ONE……..

7. When allied armies reached the Rhine, the first thing men did was pee in it. This was pretty universal from the lowest private to Winston Churchill (who made a big show of it) and Gen. Patton (who had himself photographed in the act).

8. German Me-264 bombers were capable of bombing New York City, but they decided it wasn’t worth the effort.

9. German submarine U-1206 was sunk in 1945 by a malfunctioning toilet.

10. Among the first ‘Germans’ captured at Normandy were several Koreans. They had been forced to fight for the Japanese Army until they were captured by the Russians and forced to fight for the Russian Army until they were captured by the Germans and forced to fight for the German Army until they were captured by the US Army.

AND LAST….

11. Following a massive naval bombardment, 35,000 United States and Canadian troops stormed ashore at Kiska, in the Aleutian Islands. 21 troops were killed in the assault on the island. It would have been far worse if there had actually been any Japanese on the island!
