How does the Gripen E compare to the F-35 in terms of stealth capabilities?

The Gripen E lacks the stealth capabilities of the F-35. The F-35's stealth is a significant advantage in reducing enemy detection range, especially against older radars. However, stealth is conditional and depends on various factors like radar power and processing ability. Last fact-checked: 2025-11-23.

What are the cost differences between the Gripen E and the F-35?

The Gripen E is significantly cheaper to operate than the F-35. The flight-hour cost for the F-35 is about $40,000 compared to $10,000 for the Gripen E. Over its lifespan, the F-35 can cost more than twice as much as the Gripen E. Last fact-checked: 2025-11-23.

Why is software considered crucial in comparing fighter jets like Gripen E and F-35?

Software is crucial because it significantly impacts the operational effectiveness of fighter jets. The Gripen E's software architecture allows for better decision support and easier upgrades. This can lead to effectiveness increases of several hundred percent, as demonstrated by Sweden's FOI tests. Last fact-checked: 2025-11-23.

When is the F-35 Block 4 expected to be available?

The F-35 Block 4 is expected to be available in the coming years, though delays are possible. The Gripen E is almost a completely new aircraft, while Block 4 is still in development. Timing and configuration differences complicate direct comparisons. Last fact-checked: 2025-11-23.

Which aircraft, Gripen E or F-35, has better speed and fuel efficiency?

Gripen E generally has better speed and fuel efficiency than the F-35. It is 10–20% faster overall, both in max speed and on dry thrust. The F-35's design for stealth and STOVL limits its speed and range capabilities. Last fact-checked: 2025-11-23.

What are the implications of operating a mixed fleet of fighter jets?

Operating a mixed fleet offers role optimization and reduces vendor leverage. Countries like the UK and Germany use different aircraft for different roles, benefiting from diverse capabilities. A single-supplier fleet limits adaptability to changing realities. Last fact-checked: 2025-11-23.

How does the generational classification affect the comparison between Gripen E and F-35?

Generational classification affects comparisons by oversimplifying capabilities. The F-35 is fifth-generation due to stealth, while Gripen E is 4.5 but has advanced decision-support systems. The generational system is considered too simplistic to capture the full capabilities of these aircraft. Last fact-checked: 2025-11-23.

Gripen E vs F-35? The Wrong Question to Ask

Mikael Grev is a former Gripen pilot and co-founder and CEO of Avioniq. In this column for Nordic Defence Sector, he compares the Gripen E and the F-35, arguing for a more nuanced view of fighter capabilities, procurement choices, and the strategic benefits of operating a mixed fleet.
