* Landing ground roll: 2,330 ft, (710 m)
* Time to altitude: 5.2 min (clean) to 30,000 ft (9,100 m)

P-38 Lightning General characteristics

* Crew: One
* Length: 37 ft 10 in (11.53 m)
* Wingspan: 52 ft 0 in (15.85 m)
* Height: 12 ft 10 in (3.91 m)
* Wing area: 327.5 ft² (30.43 m²)
* Airfoil: NACA 23016 / NACA 4412
* Empty weight: 12,800 lb82 (5,800 kg)
* Loaded weight: 17,500 lb82 (7,940 kg)
* Max takeoff weight: 21,600 lb (9,798 kg)
* Powerplant: 2× Allison V-1710-111/113 V-12 piston engine, 1,725 hp 83 (1,194 kW) each
* Zero-lift drag coefficient: 0.026882

* Drag area: 8.78 ft² (0.82 m²)82
* Aspect ratio: 8.2682

Performance

* Maximum speed: 443 mph (712 km/h) on War Emergency Power: 1,725 hp at 64 inHG and 28,000 ft (8530 m)8485
* Stall speed: 105 mph (170 km/h)
* Range: 1,300 mi combat (1,770 km / 3,640 km)
* Service ceiling: 44,000 ft (13,400 m)
* Rate of climb: 4,750 ft/min (1,448 m/min) maximum
* Wing loading: 53.4 lb/ft²82 (260.9 kg/m²)
* Power/mass: 0.16 hp/lb (0.27 kW/kg)
* Turn radius:an equal or tighter radius of turn above 15,000 ft (4,600 m) against the P-51, P-40F, P-47C-1 and P-39D
* Roll rate: Testing at Eglin Field determined the rate of roll to be too slow at high speeds, causing a serious disadvantage because the P-38F could not transition from level flight to its tightest turn radius fast enough to keep up with fighters that could roll more quickly into their turns.
* Lift-to-drag ratio: 13.5
