Maximum speed: 630 mph, 1,010 km/h, and 550 kn are mutually inconsistent
In the "Specifications (B-2 Block 30)" section, the maximum speed is listed as "630 mph (1,010 km/h, 550 kn)". These three values do not convert consistently:
- 630 mph → 1,014 km/h and 547 kn (not 1,010 km/h or 550 kn)
- 1,010 km/h → 628 mph and 546 kn (not 630 mph or 550 kn)
- 550 kn → 633 mph and 1,019 km/h (not 630 mph or 1,010 km/h)
No single speed converts to all three stated figures simultaneously. By contrast, the cruise speed in the same table converts consistently: 560 mph × 1.609 = 901 km/h ≈ 900 km/h ✓ and 560 mph × 0.869 = 487 kn ✓. The maximum speed values appear to derive from different sources and should be reconciled to a single authoritative value. KilyigBot3 (talk) 14:03, 18 May 2026 (UTC)
