Few aircraft of any era match the Mustang’s combination of range, speed and staying power.
North American Aviation completed the prototype airframe 102 days after the contract was signed in 1940, hung a Packard-built Merlin on the design three years later, and produced a fighter that could escort heavy bombers from England to Berlin and still fight when it arrived.
Around 150 airframes remain airworthy worldwide, almost all of them P-51D models flown on Limited category certificates by collections and private owners.
Eighty years after the last wartime delivery, the type is better supported than most out-of-production airframes of its generation.

History and Overview
Development and Background
The British Purchasing Commission approached North American Aviation in early 1940 wanting Curtiss P-40s built under license. The company offered a new design instead and completed the NA-73X airframe 102 days after the contract was signed, flying it on 26 October 1940. The RAF took the Allison-engined result into service as the Mustang Mk I in January 1942, using it for low-level tactical reconnaissance where its poor high-altitude performance did not matter.
Rolls-Royce test pilots at Hucknall fitted Merlin 65 engines to a small batch of airframes in 1942 and the aircraft’s character changed completely. North American adopted the swap using the Packard-built V-1650 and produced the P-51B and P-51C, as the Museum of Flight records. Performance above 25,000ft went from mediocre to class leading, and the Mustang became the escort fighter the Eighth Air Force had been waiting for.
The P-51D arrived in 1944 with a cut-down rear fuselage, a bubble canopy and six guns in place of four. It became the definitive variant, accounting for roughly half of all Mustangs built and the large majority of those flying today.
Design and Performance
Range came from the airframe rather than from brute fuel capacity. The laminar flow wing and the belly radiator duct, which recovered a little thrust from the cooling airflow, gave the Mustang a cruise drag figure no other single-engine fighter of the period matched. On 184 gallons of internal fuel it could reach Berlin and fight on arrival.
Construction is all-metal stressed skin, built when that was still comparatively new for fighters. The airframe is stressed to +8.0 and -4.0g and remains cleared for most aerobatic maneuvers in civil use, excluding sustained inverted flight, snap rolls, outside loops and inverted spins.
Systems are simple by later standards, which is part of why the type survives in numbers. A 1,000 psi hydraulic system operates the gear and flaps, the electrical system is 24 volt DC with a 100 amp generator, and the wheel brakes are non-boosted and fed from individual master cylinders. Nothing on the aircraft needs test equipment a well-equipped shop does not already own.
Variants
- Mustang Mk I, P-51 and P-51A — Allison V-1710 engines, strongest below 15,000ft. Flown by the RAF for tactical reconnaissance from 1942.
- A-36A Apache — Dive bomber development with dive brakes and bomb racks. 500 built.
- P-51B and P-51C — First Merlin Mustangs, razorback fuselage and four guns. B built at Inglewood, C at Dallas.
- P-51D — Bubble canopy, cut-down rear fuselage and six 0.50in guns. The definitive variant and the one almost always seen on the warbird circuit.
- P-51K — Dallas-built equivalent of the D, fitted with an Aeroproducts propeller.
- P-51H — Lightweight redesign, faster and lighter than the D, with smaller wheels and tires. 555 built and very few survive.
- F-6 series — Photographic reconnaissance conversions of the A, B, C, D and K.
- CA-17 and CA-18 Mustang — Commonwealth Aircraft Corporation production in Australia, including 80 assembled from North American parts.
- Cavalier Mustang — Postwar civil conversion by Trans Florida Aviation with a second seat, tip tanks and executive avionics. Around 20 built.
- TF-51D — Two-seat dual control conversion, originally by TEMCO and produced again in recent decades.
Operators
The USAAF was the largest wartime operator, alongside the RAF, RAAF, RCAF, RNZAF and the Chinese Nationalist air force. Postwar the type spread through Latin America, Israel, Sweden, Italy and Indonesia, and the Dominican Air Force flew Mustangs until 1984, the last military operator anywhere.
Civil ownership now accounts for the entire active fleet. The Commemorative Air Force, Planes of Fame, Comanche Fighters, Fagen Fighters and the Fighter Collection at Duxford all operate examples, and the balance sit in private hands flying airshow and heritage work.
Current Status
US production ended in 1945, with Commonwealth Aircraft Corporation continuing in Australia into the early 1950s. Roughly 150 airframes are airworthy worldwide according to the P-51 survivor register, with about 155 on the US civil register and around seven changing hands in an average year.
Values run from approximately $1.6 million for a substantial project to $3.5 million for a well restored flying aircraft, and past $5 million where combat provenance is documented. Support is better than the airframe’s age suggests: several shops manufacture parts under PMA, and the Packard V-1650 carries a civil TBO of about 600 hours with overhaul capacity available. Only one airworthiness directive applies to the type, 81-13-06, requiring periodic corrosion inspection of the Hamilton Standard propeller, as the type profile published for buyers sets out.
P-51 Mustang Landing Gear and Tires
Landing Gear Configuration
The Mustang uses retractable conventional gear with a notably wide main track, actuated by the aircraft’s 1,000 psi hydraulic system. The main legs retract inboard into the wing and the tailwheel retracts into the fuselage behind a pair of doors. Wheel brakes are non-boosted and hydraulically operated from individual master cylinders at the rudder pedals.
Tailwheel steering runs through an interconnect from the rudder pedals. Moving the stick fully forward unlocks it, at which point the wheel castors freely and steering falls to differential braking. Ground handling is unforgiving on this type, and tyres take a hard life during three-point arrivals and tight taxi turns as a result.
The single airworthiness directive on the aircraft, 81-13-06, concerns the propeller rather than the gear. Wheel, brake and tire condition are governed by the operator’s inspection program and the P-51D maintenance manual.
P-51 Mustang Tire Specifications
| Main gear tire size | 27 inch, Type I smooth contour |
| Main gear ply rating | 8PR per the Goodyear application chart. Goodyear’s current production tire in the size carries a 10PR rating |
| Tail wheel tire size | 12.5×4.5 |
| Tail wheel ply rating | Not stated against the P-51 in the Goodyear application chart. The same size is listed at 10PR on other types |
| Main wheel dimensions | 14 inch specified rim diameter, 8.94 inch between flanges |
| Main tire inflated dimensions | 26.95 to 27.78 inch outside diameter, 9.75 inch section width |
| Rated load and speed | 5,500 lb at rated inflation, 120 mph rated speed (Goodyear 270A01B3) |
| Compatible brands | Goodyear; Specialty Tires of America (Aero Classic) in the warbird sizes |
| Part numbers | Goodyear 270A01B3 (27 inch, 10PR, Aircraft Rib) |
Verify specifications against the aircraft’s Airworthiness Maintenance Manual and applicable airworthiness directives before ordering. Inflation pressures are set by the AMM for the specific airframe and configuration. Serial number, wheel type and any postwar modification can change the tire requirement.
Main Gear Tires
Main gear loading is high for a piston single. A 12,100 lb wartime maximum takeoff weight sitting on two main tires put the 27 inch Type I casing near the top of its capability, which is why the Goodyear application chart lists an 8 ply rating for the type rather than the lighter ratings normal on general aviation aircraft.
The current production tire in the size is the Goodyear Aircraft Rib 270A01B3, a 10 ply rating casing rated at 5,500 lb and 120 mph on a 14 inch rim. It is a tubeless construction used with a tube on this application, and it is the practical replacement where the original 8 ply rating specification is quoted. Goodyear’s application chart and databook carry both the fitment and the full dimensional data.
Specialty Tires of America produces warbird sizes under the Aero Classic name in both the historical diamond tread and a modern rib tread. Restorers generally choose the diamond pattern for period accuracy and the rib pattern where the aircraft flies regularly from paved runways. Confirm current availability in the 27 inch size before committing, since vintage sizes move in and out of production.
Tail Wheel Tire
The tailwheel takes a 12.5×4.5 tire. Goodyear lists that size against the P-51 in its application chart but gives no ply rating for the type, and the size does not appear in the company’s current tire specification tables, so it is sourced through warbird tire specialists rather than from mainstream general aviation stock. Confirm size, ply rating and tailwheel assembly configuration against the P-51D maintenance manual before ordering.

FAQs
Is the P-51 Mustang still in production?
No. US production ended in 1945 and Commonwealth Aircraft Corporation closed out Australian production in the early 1950s. Around 150 airframes remain airworthy, and tires, wheels and brake parts for the type are still obtainable through warbird channels.
How many P-51 Mustangs are still flying?
Roughly 150 worldwide, with about 155 on the US civil register including aircraft under restoration. Numbers move slowly in both directions as projects are completed and airframes are retired to static display.
What are the P-51 Mustang specifications?
The P-51D carries one pilot behind a 1,490 hp Packard V-1650-7 Merlin, with a 12,100 lb maximum takeoff weight, 184 US gallons of internal fuel, a 41,900ft service ceiling and 3,475 ft/min of climb. Maximum speed is 437 mph at 25,000ft. The table above lists dimensions and weights in full.
What is the range of the P-51 Mustang?
About 1,650 statute miles, or 1,434 nautical miles, on internal fuel. Wartime escort missions extended that considerably using drop tanks of up to 110 gallons each. Civil operators plan around a two hour endurance at 65 US gallons per hour with a small reserve.
What is the P-51 Mustang price?
Substantial projects list from around $1.6 million. Restored, flying aircraft sit between roughly $2 million and $3.5 million depending on restoration quality and engine time, and documented combat provenance pushes examples past $5 million. A TF-51D dual control conversion adds materially to the figure.
What does a P-51 Mustang cost to operate per hour?
Fuel alone runs 65 US gallons per hour. The dominant variable is engine reserve: the Packard V-1650 has a civil TBO of roughly 600 hours and an overhaul is a six-figure job, so most owners budget several hundred dollars an hour against that before fuel, insurance and maintenance. An annual inspection on a sound aircraft is comparatively modest.
Where can I find a P-51 Mustang for sale?
Listings appear on Controller, Trade-A-Plane, Barnstormers and AvBuyer, and specialist warbird brokers handle most transactions privately. Supply is thin, with roughly seven US aircraft changing hands in an average year.
What is the P-51 Mustang landing distance?
Operators generally want 3,000ft of runway or more, and most fly from considerably longer surfaces. Approach speeds are high for a piston single, brake energy is significant at typical landing weights, and directional control demands attention through the rollout. Consult the P-51D pilot’s handbook for figures at your operating weight and conditions.
What tire size does the P-51 Mustang use?
Main gear tires are the 27 inch Type I size, listed at an 8 ply rating in the Goodyear application chart. The tailwheel takes a 12.5×4.5 tire. The P-51H used smaller wheels and tires than the D, so confirm the size against the AMM for your serial number and configuration before ordering.
Which tire brands are approved for the P-51 Mustang?
Goodyear produces the 27 inch main gear size as the Aircraft Rib 270A01B3. Specialty Tires of America manufactures warbird sizes under the Aero Classic name in diamond and rib tread, and is frequently the only US source for the older casings. Availability in vintage sizes varies, so confirm the part number and ply rating before ordering.
How much do P-51 Mustang tires cost?
Considerably more than general aviation sizes and less than transport category tires. The 27 inch main gear casing is a low-volume item and prices reflect that. Tubes are a separate line item, and the tailwheel size is priced as a specialist product rather than a stock general aviation tire.
What is the tire pressure for the P-51 Mustang?
Take the figure from the P-51D maintenance manual for your airframe and wheel configuration rather than from a general reference. Tire manufacturer data gives rated inflation at rated load, which is not the same thing as the aircraft service pressure. Pressure is checked before every flight on this type.
How long do P-51 Mustang tires last?
Fewer landings than the equivalent general aviation tire, because the aircraft is heavy, fast on the runway and hard on rubber during three-point arrivals. Most Mustangs also fly low annual hours, so ozone and ultraviolet degradation, sidewall cracking and flat-spotting from long hangar storage retire tires as often as tread wear does.
How often should P-51 Mustang tires be changed?
Replace when tread reaches the wear limit, when cord or fabric is visible, or when cuts, cracking or flat spots are found at inspection. Aircraft that sit for long periods between airshow seasons need the sidewalls checked carefully. A licensed engineer and the maintenance manual govern the final call.
