Detailed analysis of the total cost of a fifth-generation fighter jet: acquisition, maintenance, training, ammunition, and MCO.

Acquiring a fifth-generation fighter jet is much more than just a purchase. Beyond the initial purchase price, the total cost of ownership includes considerable expenses related to pilot training, maintenance, ammunition, and operational maintenance (MCO). These costs, which are often underestimated, can represent several times the purchase price of the aircraft over its operational life. In this article, we will take a detailed look at these various expense items to understand the true cost of owning a 5th generation fighter jet.

Initial acquisition cost

The cost of acquiring a 5th generation fighter jet is a significant expense, far beyond the simple unit price of the aircraft. For example, the Lockheed Martin F-35A, the standard version with conventional takeoff, is currently priced at around $80 million per unit. This figure varies depending on configuration options, onboard systems, and negotiated purchase volumes. The F-35B, with short takeoff and vertical landing capabilities, often exceeds $100 million. By comparison, the Dassault Rafale F4, although equipped with advanced systems, is classified as a 4++ generation aircraft, with an estimated unit production cost of $70 million, excluding optional equipment and integrated weapons.

But these figures represent only the tip of the iceberg. The overall cost of a program such as the F-35, which began in the 1990s, includes not only the production of more than 3,000 aircraft, but also development, testing, infrastructure, training, and logistical support costs. According to official data from the US Government Accountability Office, the total cost of ownership of the F-35 is estimated at over $1 trillion, or approximately €930 billion, over a period of 55 years. This figure includes initial research expenditure, integrated logistics, software, simulators, and technical infrastructure upgrades. In other words, the visible unit price does not reflect the full financial commitment required to acquire a fifth-generation fighter jet. This is a government program involving multi-year budgets and long-term strategic dependence on supply chains and related services.

Maintenance and MCO costs

Operational maintenance and servicing are one of the largest items in the overall budget for a fighter jet. For a 5th generation aircraft, these recurring costs can represent between 45% and 60% of the total cost of ownership over its entire life cycle, i.e. an average operating life of between 30 and 40 years. Contrary to popular belief, the expense does not stop after purchase: every hour of flight, every part replaced, and every technical inspection has a significant impact on public finances.

For the Dassault Rafale, estimates by the French Defense Procurement Agency (DGA) put the annual maintenance cost at between $2.7 million and $3.5 million per aircraft. This includes spare parts, regular inspections (preventive and corrective), ground crew, maintenance of Snecma M88 engines, and the necessary logistical infrastructure (hangars, test benches, workshops).

In the case of the F-35, these costs are even higher. The most recent estimate puts the hourly flight cost for the F-35A version at €41,000. This figure can be explained by the aircraft’s technological density, its sensitivity to weather conditions, the complexity of its stealth coatings, and its dependence on a global supply chain centralized at Lockheed Martin. In addition, the integrated systems (sensors, ALIS/ODIN software architecture, electronic warfare) require continuous monitoring and regular updates.

Added to these direct costs are those of outsourced or semi-internalized MCO, including long-term industrial support contracts. These services, which are necessary for the operational availability of the fleet, represent a critical lever in budget planning. An aircraft that is not available for flight costs just as much, without producing any effective military capability.

The cost of pilot training

Training fighter pilots is a critical and particularly high investment in the life cycle of a fifth-generation fighter aircraft. It is not just a matter of teaching piloting, but of training personnel capable of mastering complex combat systems, including data fusion, electronic warfare, high-speed maneuvers, and networked flight. The initial training of a pilot to operational standard, including the theoretical phase, simulators, training on training aircraft (such as the Pilatus PC-21 or the Alphajet) and then on combat aircraft, can cost a total of $5 to $8 million per pilot.

Qualification on a fifth-generation fighter aircraft such as the F-35 requires in-depth familiarization with fully integrated systems, including mission software, augmented vision helmets, and multifunctional sensory interfaces. These specific features increase training time and costs. The intensive use of high-fidelity simulators helps to limit some of the costs, but cannot replace real training.

Once qualified, a pilot must fly approximately 180 to 200 hours per year to maintain their tactical and technical skills. Each hour of flight requires several hours of maintenance and preparation. For a Rafale, this represents between 6,000 and 6,400 hours of maintenance per aircraft each year. This volume of activity, combined with the salary costs of pilots (qualified senior officers), fuel costs, logistics, and training infrastructure, amounts to $800,000 to $1 million per aircraft per year.

In the case of the F-35, dependence on specific training infrastructure and proprietary software imposes even higher costs, estimated at between $1.2 million and $1.5 million per year per pilot. The complexity of the systems and the management of software obsolescence make training updates frequent, increasing the budgetary burden. These expenses are unavoidable to ensure operational availability and the safety of modern fighter aircraft missions.

The cost of ammunition and armament

Armament is a major budget item in the ownership of a fighter aircraft, particularly for 5th generation aircraft designed to use a wide range of smart munitions. Unlike older aircraft, these platforms are optimized for high-value precision-guided weapons, whether for air-to-air, air-to-ground, or multi-role support missions. This ammunition, most of which is non-reusable, must be replenished regularly, including outside of conflicts, for exercises and live firing.

A medium-range air-to-air missile such as the MICA EM or MICA IR, commonly integrated into the Rafale, costs around $2 million per unit. The Meteor, a new-generation long-range air-to-air missile, costs $2.5 to $3 million depending on the contract. On the air-to-ground side, a SCALP-EG cruise missile, used for long-range strategic strikes, costs nearly $1 million per shot. GBU-12 Paveway II guided bombs, used in tactical support missions, are valued at between $35,000 and $70,000 each, depending on the guidance kit and bomb body used.

The costs are even higher for ammunition compatible with the F-35. The JSOW (Joint Standoff Weapon), used for air-to-ground strikes at a safe distance, exceeds $300,000, while an AIM-120 AMRAAM missile used for air interception is estimated at $1 million. These weapons must be compatible with the aircraft’s internal bays to maintain stealth, which limits options and increases design costs.

Added to these costs are those associated with batch obsolescence, inventory maintenance, pilot training in the actual use of weapons systems, and requalification campaigns. In real or simulated conditions, ammunition is used on a regular basis to maintain a high level of operational readiness. Each training shot with live ammunition, each test or demonstration mission contributes to a significant increase in the annual operating budget allocated to each fighter jet.

The cost of owning a fifth-generation fighter jet far exceeds the initial purchase price. When maintenance, MCO, pilot training, and ammunition costs are factored in, the total cost over the aircraft’s lifetime can reach several hundred million dollars. It is therefore essential for armed forces to take all these factors into account when purchasing new fighter jets.
