The P-51 Mustang is the plane that won the battle over Germany. Other planes contributed but it was the Mustang that turned the air war over Germany irreversibly in the Allies’ favor. The Mustang had what every fighter plane should have, speed, maneuverability, and range. No study of military aviation development is complete unless it includes the Mustang.
The Mustang in World War II
The Mustang I had an engine without a supercharger. This meant its performance dropped off sharply above 17,000 feet. The USAAF[i] ordered a small number of Mustangs, designated P-51As and A-36s, for the ground attack role. The RAF liked the airframe so they looked for a supercharged engine that would improve its performance at high altitude. The P-51s were fitted with a Merlin 61 engine and this variant was the P-51B.[ii]
The Merlin engine solved not only the Mustang’s deficiency but a USAAF 8th Air Force deficiency. The high bomber losses over Germany forced the 8th Air Force to prohibit bombing mission beyond the range of escort fighters. The P-51Bs had the range to escort the bombers to any target in Germany.
On December 5, 1943 P-51s flew their first escort mission. The missions were over France and it was a relatively uneventful mission. The fighters didn’t shoot down any aircraft and the 8th Air Force lost only one fighter, a P-47, and 9 bombers. On December 11th an 8th Air Force P-51 scored its first kill and the first P-51 was lost. The Mustangs began to make their presence felt on March 6, 1944. The bombing targets were in Berlin. The 8th Air Force lost 69 heavy bombers and had another 6 written off. The 8th Air Force also lost 11 fighters, 5 of them Mustangs. The Luftwaffe lost 80 aircraft. The 8th Air Force sent 100 P-51s on this mission. The 8th Air Force credited the Mustangs with 43 air victories compared to 36 victories credited to the 615 P-47s that flew on the mission. This marked the turning point of the battle over Germany. From March 6 to March 23 the 8th Air Force credited Mustang pilots with shooting down 188 Luftwaffe aircraft for the loss of 44 Mustangs.[iii]
The number of escorting Mustangs grew and the ability of Luftwaffe fighters to reach the heavy bombers diminished:
- April 24, 1944 the 8th Air Force dispatched 246 P-51s. The total 8th Air Force effort was 754 heavy bombers and 867 fighters. Mustangs claimed 64 enemy aircraft in the air and 21 on the ground. P-51 losses were 12. Total enemy loss claims by fighters were 70 in the air and 58 on the ground. Eighth Air Force losses were 40 heavy bombers lost, one written off, and 17 fighters, with a P-38 written off. [iv]
- May 12, 1944 the 8th Air Force dispatched 381 P-51s. The total 8th Air Force effort was 886 heavy bombers and 735 fighters. Total enemy loss claims by fighters were 61 in the air and 5 on the ground. Mustangs claimed 33 enemy aircraft in the air and the 5 on the ground. Three Mustangs were lost. Eight Air force losses were 46 bombers and 9 written off and 7 fighters. [v]
- May 19, 1944 the 8th Air Force dispatched 363 P-51s. The total 8th Air Force effort was 888 heavy bombers and 700 fighters. Total enemy loss claims by fighters were 70 in the air and 7 on the ground. Mustangs claimed 41 enemy aircraft in the air and 4 on the ground. The 8th Air Force lost 11 Mustangs and 8 other fighters. Bomber losses were 28 shot down and 2 damaged beyond repair.[vi]
- May 27, 1944 the 8th Air Force dispatched 302 P-51s. The total 8th Air Force effort was 1,126 heavy bombers and 710 fighters. Total enemy loss claims by fighters were 35 ½ in the air and 9 on the ground. Mustangs claimed 35 ½ enemy aircraft in the air and 7 on the ground. The 8th Air Force lost 6 Mustangs and a P-38. Bomber losses were 24 shot down and 2 damaged beyond repair.[vii]
- May 30, 1944 the 8th Air Force dispatched 302 P-51s. The total 8th Air Force effort was 928 heavy bombers and 672 fighters. Total enemy claims by fighters were 50 in the air and 7 on the ground. Mustangs claimed all the ground victories and 48 air victories. The 8th Air Force lost 8 Mustangs and a P-47. Bomber losses were 12 shot down and 3 damaged beyond repair. [viii]
In May 1944 8th Air Force P-51s claimed 362 ½ enemy aircraft for the loss of 91 Mustangs and another 9 written off. The P-51 losses were from all causes.
The 15th Air Force began receiving P-51s in April 1944. The 15th Air Force Mustangs had their first major engagement on April 21, 1944. P-51s claimed 17 enemy aircraft for the loss of 2 Mustangs.[ix]
In July, 1944 Major Erich Hartmann who had 235 air victories to his credit[x] went after 4 Mustangs that were attacking another Bf 109. He shot down one P-51 and damaged another then other Mustangs came after him. He ordered his wingman to return to base. Hartmann soon was sandwiched between 8 Mustangs. Hartmann realized had the Mustang pilots been better shooters he would be dead. Hartmann’s plan was to keep turning and make his way back to his base where the base’s anti-aircraft guns would drive off the Mustangs. Before this happened the P-51 showed another advantage it had over its adversaries. Hartmann ran out of fuel and had to bail out.[xi] In this as in many other cases the aircraft with more fuel wins. In that combat P-51s shot down nearly ½ of the fighters in his Gruppe.[xii] As a result of this action orders came down that the unit was to no longer attack American fighters.[xiii]
Then General of the Luftwaffe fighter arm, Adolf Galland, went up in an FW 190 one day to survey an air battle. He shot down a straggling USAAF heavy bomber. Four Mustangs attacked him. He wrote in his book “I simply fled”.[xiv] He couldn’t outrun the P-51s. He saved himself by a ruse he previously used in the Battle of Britain. He opened fire with his guns. In such circumstances the opposing pilots couldn’t tell if the rounds were coming or going. If any of the empty shell casings struck the opposing aircraft that would give them more reason to believe they were being attacked. The Mustang pilots broke off their attack. On April 26, 1945 Galland attacked a B-26 formation with his Me 262 jet fighter. He shot down one and damaged a second. He turned to see what happened with the second B-26 when a Mustang gave Galland’s jet a long burst. The Mustang’s .50 caliber bullets heavily damaged his Me 262 and Galland was wounded. Galland would have bailed out except for rumors he heard of American pilots attacking jet pilots in their parachutes. He gave his aircraft another try and got one engine restarted. He returned to base and spent the remainder of the war in the hospital.
On November 8, 1944 Major Walter Nowotny and 5 other Me 262 jet fighters took off to attack the 8th Air Force bomber formations. Nowotny had shot down 257 enemy aircraft. He shot down a P-51D piloted by Lt. Robert W. Stevens. Then he reported one of his engines failed. It’s unknown if it was an engine malfunction or if it was battle damage. Nowotny was shot down and killed by other P-51s.[xv] Soon after Nowonty’s death the Luftwaffe disbanded Kommando Nowotny.

The Israeli Air Force acquired some P-51s in the fall of 1948. On November 20, 1948 Wayne Peake, a Gentile volunteer from America, intercepted a high flying RAF Mosquito. There was a failure in Peake’s oxygen system which blurred his vision. He fired a short burst before he ran out of ammunition. He thought the Mosquito got away. The Mosquito exploded over the Mediterranean. This caused the RAF to suspend reconnaissance flights over Israel. An Israeli P-51 is believed to have scored another air victory in its War of Independence.[i]
Mustangs flew missions in the 1956 Sinai Conflict. On one mission 6 P-51s attacked a convoy and destroyed 12 tanks and at least 25 other vehicles. Of the 15 planes the Israelis lost in the Sinai Conflict 10 were P-51s. Although the Egyptian Air Force had modern jet fighters, for 1956, all of the P-51 losses were to ground fire. [ii]

In 1945 North American developed the P-82 Twin Mustang. The P-82 was an attempt to deal with pilot fatigue from long range missions. The Twin Mustang had 2 P-51 fuselages mated together. One pilot would fly the plane to its patrol area and the other pilot would engage in combat.
On September 18, 1947 the United States Air Force (USAF) became a separate service. Among the changes the USAF made was to change the designation for fighter aircraft from “P” for Pursuit to “F” for Fighter. So the Mustangs in the USAF were referred to as the F-51s and the Twin Mustangs were referred to as F-82s.
North Korea invaded South Korea on June 25, 1950. The next day P-82s flew air cover over Inchon harbor. A North Korean fighter unsuccessfully attacked a pair of F-82s. The next day there was an air combat between 5 USAF F-82s and 5 North Korean Yak fighters. The F-82 shot down 3 of the Yaks without loss. These were the first air-air victories of the Korean conflict and the only victories for the F-82s. The USAF credited Lieutenants William G. Hudson and Charles B. Morgan, and Major James W. Little with the victories.[i]
The F-51s scored their first Korean air victories on June 29th. The Mustangs downed 4 Yaks. Lt. Orrin Fox scored 2 of these victories. Four members of the USAF received the Medal of Honor, all posthumously, during the Korean Conflict. One of these recipients was F-51 pilot Major Louis Sebille who after being wounded on a strafing mission crashed his Mustang into 2 partially hidden half-tracks. On December 28th a ground attack by Mustangs convinced 100 Chinese soldiers to surrender. Lt. J.G. Harrison scored the last air victory for an F-51 on June 20, 1951. He shot down a Yak fighter. That day a MiG-15 shot down an F-51. The USAF F-51s continued flying ground attack missions in Korea until January 1953. The Republic of Korea Air Force flew the F-51s missions until the cease fire and beyond. [ii]

Thank you for reading and commenting. I'm glad you found it interesting. An article about the USAF, a big topic.
RTalloni on April 04, 2019:
An interesting read about the Mustang and the battles you've mentioned. I didn't know the date the USAF was established as separate. September 18 might be a good day for you to post an article on the USAF.
Robert Sacchi (author) on January 30, 2018:
Thank you for reading and commenting. Mustangs were also used in the 1969 "Soccer War". In that one the Mustangs were defeated by Corsairs.
ata1515 from Buffalo, New York. on January 30, 2018:
Interesting statistics regarding the utility in various wars throughout the ages, you’ve provided a great compilation here.
Robert Sacchi (author) on July 12, 2017:
Yes, the exhaust driven supercharger, the turbosupercharger, is what gave many American fighters a big advantage at high altitudes. Since the heavy bombers normally flew at high altitudes it made these fighters excellent for fighter escort. Thank you for reading and commenting.
Peggy Woods from Houston, Texas on July 11, 2017:
This is an interesting article as always Robert when it comes to describing aircraft. Reading the comments it was also interesting that Randy Godwin flew in the two seated version of the P-51. I had never heard of engines being supercharged but it makes sense for those wishing to fly in higher altitudes. I always learn much by reading your posts about the different airplanes.
Robert Sacchi (author) on May 01, 2017:
Yes, was the range that put it in a class by itself. There were other fighters that could match its performance, the Spitfire and Tempest for example, but not its range.
Lawrence Hebb from Hamilton, New Zealand on May 01, 2017:
Great article, the P51 had an incredible range.
Robert Sacchi (author) on April 05, 2017:
Setank Setunk, thank you. Yes, the Mustang's range, and its ability to perform as good or better than its contemporaries that lacked its range, made it a really exceptional aircraft in 1943/1944.
Setank Setunk on April 05, 2017:
The Mustang is a very good fighter and ground attack platform. It benefits from being used for it's range at the point when a change in strategy broke the back of the Luftwaffe.
Starting in "Big Week" in 1944, massive bomber raids were conducted under Dolittle's strategy of keeping Allied fighters with the bombers and flying screens to and from the targets. Luftwaffe destroyer squadrons had to face Allied fighters and this decimated their ranks. This strategy lead to an increased bombing result which in turn reduced the number of replacement planes and pilots for the increased losses and down and down it went; Like a Market Crash.
The Mustang simply possessed the range, thanks to drop tanks, to accommodate this new strategy.
Like the B-17, the Mustang was a symbol of Allied victory and given more credit than deserved.
Robert Sacchi (author) on April 04, 2017:
Thank you Randy, I'm glad for you that you got to ride in a P-51.
Randy Godwin from Southern Georgia on April 04, 2017:
Another great article about my favorite WWII fighter, Robert. I had the honor of flying in a two seat version of the P-51 piloted by a man who flew them during the war. One cannot describe the pure power this wonderful aircraft is embodied with. I so admire those wonderful old pilots.....
Robert Sacchi (author) on April 04, 2017:
Alan , the P-51D had a Merlin inline rated at 1,695hp. The Spitfires VB & IX had Merlin V-12s rated at 1,440 hp & 1,710 hp respectively. The XIV had a Griffin 65 rated at 2,050 hp.
Robert Sacchi (author) on April 04, 2017:
Thank you C E Clark. I will have to look at Amazon-Kindle. I'm a little, pardon the pun, gunshy about aircraft articles. There are many top notch experts out there.
Alan R Lancaster from Forest Gate, London E7, U K (ex-pat Yorkshire) on April 04, 2017:
Interesting write-up on an indispensable US aircraft, Robert. RAF fighter pilots took to them like ducks to water for their versatility.
No mention here, though, of the drop tanks used by the Mustang squadrons to increase the range for bomber escort. I've seen documentaries where they were also deployed over Normandy as 'tank-busters', and very effective they were - not only on tanks. The Germans couldn't use their 'Big Bertha' either, for fear of attack by the Mustangs on Hitler's long-range heavy rail-mounted gun. This was one of the guns used in shelling the Russian cities such as Sevastopol. It took a 1,000 men half a day to set up, by which time the Mustangs were onto them.
You mention thar from when the RAF used them they were fitted with Merlin engines, although not which version. Both Spitfires and Lancaster bombers were fitted with Merlin engines but obviously not the same type. I suppose they must've been the same as used on Spitfires (then again which mark? The factories churned out a different mark of Spitfire every year of WWII).
C E Clark from North Texas on April 04, 2017:
While I've never been an airplane enthusiast, I did at least understand parts of this article better than I thought I would. ;) Seems very thorough and well written. You might consider compiling all of your articles on flying machines into a book and publishing it on Amazon-Kindle. Or grouping other articles that have commonality into a book. Last I knew, it doesn't cost anything to publish on A-K. Will post this on FB.
