Great Circle Route: Anchorage to Moscow Flies East, Not West

On a nonstop flight from Anchorage (ANC) to Moscow (SVO/DME/VKO), the shortest path follows a great circle route arcing northeast across the Arctic Ocean—not west across the Pacific.

Why East? The Geometry of Spheres

On a globe, the shortest distance between two points is a great circle arc. Anchorage (61°N, 150°W) and Moscow (56°N, 38°E) are separated by ~152° of longitude—but the polar route cuts the corner:

• Great circle distance: ~4,500 miles (7,240 km)
• Route: ANC → North over Beaufort Sea → North Pole vicinity → South over Franz Josef Land / Kara Sea → Moscow
• Direction: Initial heading ~015° (north-northeast); overall azimuth trends eastward

Why Not West?

Flying west (ANC → Japan → Siberia → Moscow) follows the rhumb line (constant compass heading) but covers ~6,500+ miles—2,000 miles longer. The earth's curvature makes the polar route dramatically shorter.

Real-World Operations

• No scheduled nonstop exists (range ~4,500 mi; requires 777-200LR/A350-900ULR; demand insufficient)
• Typical routings: ANC → SEA/ORD/DTW → SVO (1-stop, 12-15 hrs) or ANC → ICN/HND → SVO
• Polar routes: Many US-Asia/Europe flights already use Arctic corridors (FAA/ Russian FIR coordination)
• ETOPS/Regulatory: Requires polar-certified aircraft, crews, recovery airports (Yellowknife, Iqaluit, Longyearbyen)

Historical Note

Cold War: US reconnaissance (RC-135, U-2) flew similar polar tracks monitoring Soviet Arctic. Modern: Cargo flights (FedEx, UPS) ANC → Europe often use polar routes.
