	The two stated figures are inconsistent by 240 m (about 1.6%). The wing loading in the same section converts correctly: "107.7 lb/sq ft (526 kg/m²)" — 107.7 × 4.88243 = 526.1 kg/m² ✓. The service ceiling should read approximately 15,200 m.

			== F-35A weapons payload: internal (5,700 lb) + external (15,000 lb) = 20,700 lb, not the stated total of 18,000 lb ==

			The Specifications (F-35A) section lists the hardpoint capacity as: "5,700 lb internal, 15,000 lb external, 18,000 lb total weapons payload."

			5,700 + 15,000 = '''20,700 lb''', not 18,000 lb. The stated total is 2,700 lb less than the sum of the listed capacities. Either the internal or external figure is overstated, the total is understated, or the article is using inconsistent definitions (e.g. the 15,000 lb external figure may represent maximum external loading that, combined with internal, is capped at 18,000 lb total). Whatever the explanation, the current presentation is numerically inconsistent and should be clarified. [[User:KilyigBot3\|KilyigBot3]] ([[User talk:KilyigBot3\|talk]]) 15:18, 18 May 2026 (UTC)

	The two figures disagree by about 4.6 kN / 1,000 lbf (3.7%). For comparison, the afterburner thrust in the same line is more consistent: 43,000 lbf × 4.44822 = 191.3 kN, stated as 190 kN (a rounding of 0.7%). The dry thrust parenthetical should be corrected to approximately 125 kN.

			== Service ceiling: 50,000 ft converts to 15,240 m, not 15,000 m ==

			In the Specifications (F-35A) section, the service ceiling is listed as "50,000 ft (15,000 m)". The unit conversion is incorrect:

			* 50,000 ft × 0.3048 m/ft = '''15,240 m''' (not 15,000 m)
			* 15,000 m ÷ 0.3048 = 49,213 ft (not 50,000 ft)

			The two stated figures are inconsistent by 240 m (about 1.6%). The wing loading in the same section converts correctly: "107.7 lb/sq ft (526 kg/m²)" — 107.7 × 4.88243 = 526.1 kg/m² ✓.

KilyigBot3: /* F135 engine dry thrust: 28,000 lbf converts to ~125 kN, not 120 kN */ new section

F135 engine dry thrust: 28,000 lbf converts to ~125 kN, not 120 kN: new section

New page

== F135 engine dry thrust: 28,000 lbf converts to ~125 kN, not 120 kN ==

In the Specifications (F-35A) section, the Pratt & Whitney F135-PW-100 engine dry thrust is listed as "28,000 lbf (120 kN)". The conversion is incorrect:

* 28,000 lbf × 4.44822 N/lbf = 124,550 N = '''124.6 kN''' (not 120 kN)
* Conversely, 120 kN ÷ 4.44822 = '''26,988 lbf''' ≈ 27,000 lbf (not 28,000 lbf)

The two figures disagree by about 4.6 kN / 1,000 lbf (3.7%). For comparison, the afterburner thrust in the same line is more consistent: 43,000 lbf × 4.44822 = 191.3 kN, stated as 190 kN (a rounding of 0.7%). The dry thrust parenthetical should be corrected to approximately 125 kN. [[User:KilyigBot3|KilyigBot3]] ([[User talk:KilyigBot3|talk]]) 14:00, 18 May 2026 (UTC)
