Everyone knows the F-35 has problems. So why is everyone buying it?

The world’s most expensive weapons program remains plagued by technical flaws, soaring costs, and uncomfortable questions about its combat value
The F-35 multi-role fifth-generation fighter has made headlines for various reasons: its deployment in the conflict with Iran, deliveries to nations participating in the F-35 program, new missiles designed for the aircraft, and staggering operational costs. Even though production of the F-35 has surpassed 1,000 units, doubts persist regarding the program’s overall effectiveness and the aircraft’s compliance with all the standards of a fifth-generation fighter. Let’s take a closer look. 
In June 2015, a report by an American test pilot appeared online under the title F-35A High Angle of Attack Operational Maneuvers. It revealed that the latest F-35 was outperformed in a mock dogfight by the fourth-generation F-16D aircraft. Despite the F-35’s advertised advantages, it struggled to get behind the F-16D and lagged in energy maneuverability and pitch rate. What the media overlooked was that the test involved an experimental prototype of the F-35 that lacked operational combat software. Additionally, this prototype was restricted to a 5.5 G overload limit compared to the F-16’s ability to withstand up to 9 G. Once the F-35 received a full software update (starting with Block 3F), the upgraded versions decisively outperformed F-16s and other fourth-generation aircraft during Red Flag exercises – not through maneuverability, but by leveraging their stealth capabilities at long ranges without entering close combat.
Therefore, the main advantage of the F-35 fifth-generation fighter is its stealth capabilities. For the US, stealth is the defining characteristic of fifth-generation aircraft. This refers to the low radar cross-section achieved through the aircraft’s design and specialized coatings that disrupt radar wave reflection. The American strategy hinges on the belief that stealth aircraft can employ long-range missile systems while remaining undetected by enemy aircraft, effectively avoiding dogfights by striking the enemy from a distance.
The second major advantage of fifth-generation fighters is their capability for network-centric warfare, utilizing information systems that enable not only data sharing but also directing other aircraft and managing drones. An ‘invisible’ aircraft can detect adversaries either directly or through its wingmen and is capable of orchestrating attacks independently or by coordinating strikes with other planes and drones. Technically, the F-35 is already equipped for such operations.
Other characteristics of the F-35 are more problematic. For example, fifth-generation fighters have a powerful engine capable of sustained supersonic flight without using an afterburner. While the F-35 formally meets these criteria, the F-35B and F-35C variants are restricted from flying above Mach 1.2 for extended periods due to risks of thermal damage to their stealth coatings and tail surfaces. How can a supersonic jet not fly at supersonic speeds? Moreover, the F-35A appears to struggle with sustained supersonic cruising. Compounding these concerns are reports in the media regarding the P&W F135 engine. Reportedly, it faces issues like turbine blade wear, overheating, and a shortage of components for timely repairs.
On top of that, the operational cost of the F-35 is historically high. The total cost of the development and lifecycle of the F-35 has soared to nearly $2 trillion and continues to rise, making it the most expensive weapons system in history. For end users, however, the hourly flight cost is what truly matters. Operating an F-35 runs between $35,000 and $42,000 per hour, while standard F-16s operate at around $22,000 per hour. Overall, this is extremely expensive for a mass-produced fighter.
