Lockheed P-38 Lightning

2208:, 600 of these stop-gap Lightnings with an improved 20 mm cannon and a bomb capacity of 3,200 lb (1,500 kg) were produced on one line beginning in May 1943 while the near-definitive P-38J began production on the second line in August 1943. The Eighth Air Force was experiencing high-altitude and cold-weather issues which, while not unique to the aircraft, were perhaps more severe as the turbosuperchargers upgrading the Allisons were having their own reliability issues, making the aircraft more unpopular with senior officers out of the line. This was a situation unduplicated on all other fronts where the commands were clamoring for as many P-38s as they could get. Both the P-38G and P-38H models' performances were restricted by an intercooler system integral to the wing's leading edge, which had been designed for the YP-38's less powerful engines. At the higher boost levels, the new engine's charge air temperature would increase above the limits recommended by Allison and would be subject to detonation if operated at high power for extended periods of time. Reliability was not the only issue, either. For example, the reduced power settings required by the P-38H did not allow the maneuvering flap to be used to good advantage at high altitude. All these problems really came to a head in the unplanned P-38H and sped the Lightning's eventual replacement in the 8th Air Force; fortunately, the 15th Air Force was glad to get them. 392: 633:

spring-loaded servo tabs on the elevator trailing edge designed to aid the pilot when control yoke forces rose over 30 pounds-force (130 N), as would be expected in a high-speed dive. At that point, the tabs would begin to multiply the effort of the pilot's actions. Expert test pilot Ralph Virden was given a specific high-altitude test sequence to follow and was told to restrict his speed and fast maneuvering in denser air at low altitudes, since the new mechanism could exert tremendous leverage under those conditions. A note was taped to the instrument panel of the test craft underscoring this instruction. On 4 November 1941, Virden climbed into YP-38 #1 and completed the test sequence successfully, but 15 minutes later, was seen in a steep dive followed by a high-G pullout. The tail unit of the aircraft failed at about 3,500 ft (1,000 m) during the high-speed dive recovery; Virden was killed in the subsequent crash. The Lockheed design office was justifiably upset, but their design engineers could only conclude that servo tabs were

2280:. In tests, the P-38K-1 achieved 432 mph (695 km/h) at military power and was predicted to exceed 450 mph (720 km/h) at War Emergency Power with a similar increase in load and range. The initial climb rate was 4,800 ft (1,500 m)/min and the ceiling was 46,000 ft (14,000 m). It reached 20,000 ft (6,100 m) in five minutes flat; this with a coat of camouflage paint, which added weight and drag. Although it was judged superior in climb and speed to the latest and best fighters from all AAF manufacturers, the War Production Board refused to authorize P-38K production due to the two- to three-week interruption in production necessary to implement cowling modifications for the revised spinners and higher thrust line. Some had also doubted Allison's ability to deliver the F15 engine in quantity. As promising as it had looked, the P-38K project came to a halt. 3199: 2193:, using more powerful Allisons of 1,400 hp (1,000 kW) each and equipped with a better radio. A dozen of the planned P-38G production were set aside to serve as prototypes for what became the P-38J with further uprated Allison V-1710F-17 engines (1,425 hp (1,063 kW) each) in redesigned booms, which featured chin-mounted intercoolers in place of the original system in the leading edge of the wings and more efficient radiators. Lockheed subcontractors, however, were initially unable to supply both of Burbank's twin production lines with a sufficient quantity of new core intercoolers and radiators. War Production Board planners were unwilling to sacrifice production, and one of the two remaining prototypes received the new engines, but retained the old leading-edge intercoolers and radiators. 809:. British displeasure with the Lockheed order came to the fore in July, and on 5 August 1941, they modified the contract such that 143 aircraft would be delivered as previously ordered, to be known as "Lightning (Mark) I", and 524 would be upgraded to US-standard P-38E specifications with a top speed of 415 mph (668 km/h) at 20,000 ft (6,100 m) guaranteed, to be called "Lightning II", for British service. Later that summer, an RAF test pilot reported back from Burbank with a poor assessment of the "tail flutter" situation, and the British cancelled all but three of the 143 Lightning Is. As a loss around US$ 15M was involved, Lockheed reviewed their contracts and decided to hold the British to the original order. Negotiations grew bitter and stalled. Everything changed after Japanese 1105:

fighters also targeted transport aircraft, and later in the campaign, they were sometimes tasked with ground-attack missions. When tied to bomber-escort duties, the P-38 squadrons were vulnerable to attack from above by German fighters, who selected the most advantageous position and timing. The initial tactical doctrine of the American units was for the P-38s to fly near the bombers at all times rather than to defend aggressively or to fly ahead and clear the airspace for the bombers, and many American pilots were downed because of this limitation. Losses mounted, and all available P-38s in the UK were flown over to North Africa to restore squadron strength. After this painful experience, the American leadership changed tactics, and in February 1943, the P-38s were given free rein in their battles.

1557:, in which eight Japanese troop transports and four escorting destroyers were sunk. Two P-38 aces from the 39th Fighter Squadron were killed on the second day of the battle: Bob Faurot and Hoyt "Curley" Eason (a veteran with five victories who had trained hundreds of pilots, including Dick Bong). In one notable engagement on 3 March 1943, P-38s escorted 13 B-17s (part of an attack including B-25 Mitchells and Beaufighters) as they bombed the Japanese convoy from a medium altitude of 7,000 ft (2,100 m), which dispersed the convoy formation and reduced their concentrated antiaircraft firepower. A B-17 was shot down and when Japanese Zero fighters machine-gunned some of the B-17 crew members who bailed out in parachutes, three P-38s promptly dived into action, claiming five Zeros. 1628: 598: 2174:

it could enter an unrecoverable dive due to a sonic surface effect at high subsonic speeds. The 527 P-38Fs were heavier, with more powerful engines that used more fuel, and were unpopular in the air war in Northern Europe. Since the heavier engines were having reliability problems and with them, without external fuel tanks, the range of the P-38F was reduced, and since drop tanks themselves were in short supply as the fortunes in the Battle of the Atlantic had not yet swung the Allies' way, the aircraft became relatively unpopular in minds of the bomber command planning staffs despite being the longest-ranged fighter first available to the 8th Air Force in sufficient numbers for long-range escort duties. Nonetheless,

522:, commander of the USAAC, approved of the record attempt and recommended a cross-country flight to New York. The flight set a speed record by flying from California to New York in seven hours and two minutes, not counting two refueling stops. Kelsey flew conservatively for most of the way, working the engines gently, even throttling back during descent to remove the associated speed advantage. Bundled up against the cold, Arnold congratulated Kelsey at Wright Field during his final refueling stop, and said, "don't spare the horses" on the next leg. After climbing out of Wright Field and reaching altitude, Kelsey pushed the XP-38 to 420 miles per hour (680 km/h). Nearing his destination, Kelsey was ordered by 2485:

sideplane area to augment the vertical rudders. This arrangement was removed and a final third version was fabricated that had the booms returned to normal length but the tail raised 33 in (84 cm). All three tail modifications were designed by George H. "Bert" Estabrook. The final version was used for a quick series of dive tests on 7 December 1942 in which Milo Burcham performed the test maneuvers and Kelly Johnson observed from the rear seat. Johnson concluded that the raised floatplane tail gave no advantage in solving the problem of compressibility. At no time was this P-38E testbed airframe actually fitted with floats, and the idea was quickly abandoned, as the U.S. Navy proved to have enough

Corps requirement for pursuit aircraft to carry no more than 500 lb (230 kg) of armament including ammunition, and to bypass the USAAC restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (450 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt

The P-38 cannon used heavier 20 mm rounds, creating a different trajectory, so it was inclined upward slightly more than the four machine guns such that the trajectories of the cannon rounds and .50-caliber bullets came together between 350 and 400 yards. Nose-mounted guns did not suffer as much from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas the wing guns of other fighters were optimized for a specific range. The 716: 2853: 2231: 1016:. The fighter's long range made it well-suited to the campaign over the almost 1,200-mile (1,900 km)-long island chain, and it was flown there for the rest of the war. The Aleutians were some of the most rugged environments available for testing the new aircraft under combat conditions. More Lightnings were lost due to severe weather and other conditions than enemy action; cases occurred where Lightning pilots, mesmerized by flying for hours over gray seas under gray skies, simply flew into the water. On 9 August 1942, two P-38Es of the 343rd Fighter Group, 2197: 2814: 2247:

While the P-38J used the same V-1710-89/91 engines as the H model, the new core-type intercooler more efficiently lowered intake manifold temperatures and permitted a substantial increase in rated power. The leading edge of the outer wing was fitted with 55 US gal (210 L) fuel tanks, filling the space formerly occupied by intercooler tunnels, but these were omitted on early P-38J blocks due to limited availability.

600 mph (970 km/h), although the indicated air speed was later corrected for compressibility error, and the actual dive speed was lower. Lockheed manufactured over 200 retrofit modification kits to be installed on P-38J-10-LO and J-20-LO already in Europe, but the USAAF C-54 carrying them was shot down by an RAF pilot who mistook the Douglas transport for a German Focke-Wulf Condor. Unfortunately, the loss of the kits came during Lockheed test pilot Tony LeVier's four-month morale-boosting tour of P-38 bases. Flying a new Lightning named

Stigler said the Lightning "could turn inside us with ease and they could go from level flight to climb almost instantaneously. We lost quite a few pilots who tried to make an attack and then pull up... One cardinal rule we never forgot was to avoid fighting the P-38 head on. That was suicide." Stigler said the best defense was to flick-roll the Bf 109 and dive, as the Lightning was slow in the first 10° of roll, and it was not as fast in a dive. 6347: 691:) taking the shipment to England. Back in Burbank, P-38Js coming off the assembly line in spring 1944 were towed out to the ramp and modified in the open air. The flaps were finally incorporated into the production line in June 1944 on the last 210 P-38Js. Despite testing having proved the dive flaps effective in improving tactical maneuvers, a 14-month delay in production limited their implementation, with only the final half of all Lightnings built having the dive flaps installed as an assembly-line sequence. 546: 2941: 1254: 2892: 969:. Other P-38s followed this route with some lost in mishaps, usually due to poor weather, low visibility, radio difficulties, and navigational errors. Nearly 200 of the P-38Fs (and a few modified Es) were successfully flown across the Atlantic in July–August 1942, making the P-38 the first USAAF fighter to reach Britain and the first fighter ever to be delivered across the Atlantic under its own power. Kelsey himself piloted one of the Lightnings, landing in Scotland on 25 July. 585:. The first YP-38 was not completed until September 1940, with its maiden flight on 17 September. The 13th and final YP-38 was delivered to the USAAC in June 1941; 12 aircraft were retained for flight testing and one for destructive stress testing. The YPs were substantially redesigned and differed greatly in detail from the hand-built XP-38. They were lighter and included changes in engine fit. The propeller rotation was reversed, with the blades spinning outward (away from the 3285: 769: 3006: 1038: 613:), steepening the dive. Once caught in this dive, the fighter would enter a high-speed compressibility stall and the controls would lock up, leaving the pilot no option but to bail out (if possible) or remain with the aircraft until it got down to denser air, where he might have a chance to pull out. During a test flight in May 1941, USAAC Major Signa Gilkey managed to stay with a YP-38 in a compressibility lockup, riding it out until he recovered gradually using 1665:, flying reconnaissance over the Balkans, ground attack, naval cooperation, and air-superiority missions. Due to old engines, pilot errors, and lack of experience in operations, large numbers of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the scrapyard. 2170:. When deployed at the 8° maneuver setting, the flaps allowed the P-38 to out-turn many contemporary single-engined fighters at the cost of some added drag. However, early variants were hampered by high aileron control forces and a low initial rate of roll, and all such features required a pilot to gain experience with the aircraft, which in part was an additional reason Lockheed sent its representative to England, and later to the Pacific Theater. 2433: 2468: 2840: 2924: 2879: 507: 2368: 530:) into a slow landing pattern behind other aircraft. Carburetor icing caused it to be brought down short of the Mitchel runway, and it was wrecked. However, on the basis of the record flight, the Air Corps ordered 13 YP-38s on 27 April 1939 for US$ 134,284 (~$ 2.31 million in 2023) each.

The Model 822 would have featured folding wings, an arresting hook, and stronger undercarriage for carrier operations. The navy was not interested, as they regarded the Lightning as too big for carrier operations and did not like liquid-cooled engines, anyway, and the Model 822 never went beyond the paper stage. However, the navy did operate four land-based F-5Bs in North Africa, inherited from the USAAF and redesignated 2310: 2827: 3717: 49: 2866: 650:

dangerously steep test flights were flown to document their performance. Explaining to Wolfe in Report No. 2414, Kelly Johnson wrote, "the violence of the vibration was unchanged and the diving tendency was naturally the same for all conditions." The external mass balances did not help at all. Nonetheless, at Wolfe's insistence, the additional external balances were a feature of every P-38 built from then on.

1250:, while six airmen parachuted out. According to US sources, he also damaged three more bombers on that occasion. On 4 September, the 301st BG reported the loss of B-17 "The Lady Evelyn," 42–30344, downed by "an enemy P-38". War missions for that plane were limited, as the Italian petrol was too corrosive for the Lockheed's tanks. Other Lightnings were eventually acquired by Italy for postwar service. 1402: 1636:

air superiority in Europe, when pilots fought against a very determined and skilled enemy. Lieutenant Colonel Mark Hubbard, a vocal critic of the aircraft, rated it the third-best Allied fighter in Europe. The Lightning's greatest virtues were long range, heavy payload, high speed, fast climb, and concentrated firepower. The P-38 was a formidable fighter, interceptor, and attack aircraft.

830:. The A&AEE example was unarmed, lacked turbochargers and restricted to 300 mph (480 km/h); though the undercarriage was praised and flight on one engine described as comfortable. These three were subsequently returned to the USAAF; one in December 1942 and the others in July 1943. Of the remaining 140 Lightning Is, 19 were not modified and were designated by the USAAF as 934:

the result of subcontractor production variation. Arnold ordered further tests with larger drop tanks in the range of 300 to 310 US gal (1,100 to 1,200 L); the results were reported by Kelsey as providing the P-38 with a 2,500-mile (4,000 km) ferrying range. Because of available supply, the smaller drop tanks were used to fly Lightnings to the UK, the plan called

After another heavy toll in January 1943, 14th FG had to be withdrawn from the front to reorganize, with surviving pilots sent home and the few remaining Lightnings transferred to the 82nd. The 14th was out of action for three months, returning in May.

1526: 3249:. His health, both physically and mentally, had been deteriorating. Saint-Exupéry was said to be intermittently subject to depression and talk had arisen of taking him off flying status. He was on a flight over the Mediterranean, from Corsica to mainland France, in an unarmed F-5B photo-reconnaissance variant of the P-38J, described as being a "war-weary, nonairworthy craft". 3096:. Hit by cannon and machine-gun fire, the "Sonia's" propeller visibly slowed, but Shimada held his course. Lindbergh pulled up at the last moment to avoid collision as the damaged "Sonia" went into a steep dive, hit the ocean, and sank. The unofficial kill was not entered in the 475th's war record. On 12 August 1944, Lindbergh left Hollandia to return to the United States. 1182:, third-highest scoring German pilot on the Western front with 112 victories, recalled: "The P-38 fighter (and the B-24) were easy to burn. Once in Africa, we were six, and met eight P-38s and shot down seven. One sees a great distance in Africa and our observers and flak people called in sightings and we could get altitude first and they were low and slow." 2666:: This production variant was built in 1943 with improvements to each batch, notably an increase of Hp that came with an improved turbocharger. It also included chin radiators, flat bullet-proof windshields, power-boosted ailerons, and increased fuel capacity* 2970 were built. Some were modified to pathfinder configuration and to F-5C, F-5E, and F-5F. 1522:, the United States' highest-scoring World War II air ace (40 victories in P-38s), flew directly at his targets to ensure he hit them, in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft, which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific. 1506:

18,000–25,000 ft (5,500–7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpit temperatures were not a problem at low altitude in the tropics. In fact, the cockpit was often too hot since opening a window while in flight caused buffeting by setting up turbulence through the

Results of the bombing were not observed by the USAAF pilots because of the smoke. The dive-bombing mission profile was not repeated, though the 82nd Fighter Group was awarded the 467:

4,000 rpm with roughly every sixth projectile a 20 mm shell. The duration of sustained firing for the 20 mm cannon was about 14 seconds, while the .50-caliber machine guns worked for 35 seconds if each magazine were fully loaded with 500 rounds, or for 21 seconds if 300 rounds were loaded to save weight for long-distance flying.

2255:, modified to full P-38J-25-LO specifications at Lockheed's modification center near Belfast, LeVier captured the pilots' full attention by routinely performing maneuvers during March 1944 that common 8th Air Force wisdom held to be suicidal. It proved too little, too late, because the decision had already been made to re-equip with Mustangs. 2306:(HVARs) on pylons were placed beneath each wing, and later, five rockets were on each wing on "Christmas tree" launch racks, which added 1,365 lb (619 kg) to the aircraft. The P-38L also had strengthened stores pylons to allow carriage of 2,000 lb (900 kg) bombs or 300 US gal (1,100 L) drop tanks. 542:, angrily characterized the accident as an unnecessary publicity stunt, but according to Kelsey, the loss of the prototype, rather than hampering the program, sped the process by cutting short the initial test series. The success of the aircraft design contributed to Kelsey's promotion to captain in May 1939. 2590:: Former Armée de l'air order for 667 aircraft (being reduced to 143 Lighting Is), it was taken by the Royal Air Force, three delivered to RAF, and the remainder of the order was delivered to USAAF. It used C-series V-1710-33 engines without turbochargers, and right-hand propeller rotation (not counter). 1611:

P-38 J and L had tremendous success flying out of Italy into Germany at all altitudes.
