BOMBARDIER CHALLENGER 604
Bombardier Challenger 604: The Best-Seller
The 1995 Avionics Revolution
In 1995, Bombardier introduced the Challenger 604 — the aircraft that became the most popular Challenger ever built. With 365+ deliveries, the 604 combined the proven 601 airframe with Rockwell Collins Pro Line 4 "glass" avionics, more powerful CF34-3B engines, and increased fuel capacity.
Specifications That Dominated
• Range: 7,456 km (4,025 nm) — transatlantic with reserves
• Speed: 870 km/h (470 knots) — faster than predecessors
• Capacity: 10 – 12 passengers in the updated cabin
• Avionics: Pro Line 4 — first Challenger with full glass cockpit
• Production: 365+ aircraft — the best-selling Challenger variant

The 604 introduced saddle tanks for increased fuel, reinforced landing gear, and structural revisions that extended service life. It became the backbone of corporate fleets, charter operators, and government missions worldwide.
The Market Today
Pre-owned Challenger 604 aircraft trade between $3M and $6M — remarkable value for the best-selling large cabin jet. Operating costs: $2,800 – 3,500 per hour — reasonable for the capability and reliability.
The Verdict
The Challenger 604 is the aircraft that defined large cabin aviation for a generation. It took everything that worked in the 601 and modernized it for the 21st century.

For the buyer seeking a Challenger 604, you're acquiring the best-seller — the aircraft that proved Bombardier's formula was timeless.
