The study conducted by IHS Jane's Aerospace and Defense Consulting, compared the operational costs of the Gripen, Lockheed Martin F-16, Boeing F/A-18 Super Hornet, Dassault’s Rafale, Eurofighter Typhoon and the F-35 aircraft.
“At an estimated $4,700 per hour (2012 USD), the Gripen compares very favorably with the Block 40 / 50 F-16s which are its closest competitor at an estimated $7,000 per hour,” says the report, adding, “The F-35 and twin-engined designs are all significantly more expensive per flight hour owing to their larger size, heavier fuel usage and increased number of airframe and systems parts to be maintained and repaired. IHS Jane’s believes that aircraft unit cost and size is therefore roughly indicative of comparative CPFH.”
In comparison, the figure for the F/A-18 Super Hornet ranged from USD 11000 to USD 24000, depending on degree of operational capability. The figure for the Rafale was USD 16500 per flying hour and number for the Eurofighter Typhoon, derived from British Parliamentary figures and seeming to cover only fuel usage, was USD 8200. But Jane’s estimate of the actual Cost Per Flying Hour for the Eurofighter, keeping in mind supplies and scheduled maintenance raised the figure up to USD 18000.
The cost of operation of the F-35 appears to be in a whole other league. Jane’s cites Royal Australian Air Force (RAAF) estimates for the conventional F-35 A, assuming operational service over 30 years with 200 hours per year for each aircraft, to amount to USD 21000 per hour of flight. The paper also sources US Navy projections of the cost of operation of the F-35 B & C variants until the year 2029, which come to USD 31000 per flight hour.
