Following the strategic roadmap laid out by President Viktor Sotona, Filip Kulštrunk — Executive Vice President and Chief Commercial Officer at AERO Vodochody AEROSPACE a.s. — expands on how Aero is translating its vision into commercial success. In this exclusive interview, he explains how the company is addressing the growing global demand for military pilot training, why the L-39 Skyfox stands out as a versatile and cost-effective solution, and how Aero’s integrated simulation technologies are shaping the future of NATO and EU training ecosystems.
What key trends in military pilot training do you consider decisive for the next decade, and how is Aero preparing for them?
There is a clear trend of increasing demand for pilot training across all phases, especially in connection with the acquisition of new combat aircraft. Pilot training programs must be properly adjusted, otherwise these platforms will not be deployed effectively. Western countries are simultaneously preparing to increase the number of trained pilots and are expanding their training programs to fulfill both NATO obligations and national requirements.
A major shift is the growing integration of tactical and combat elements into the early stages of training — areas that used to be taught much later. Training aircraft like the L-39 Skyfox now incorporate onboard simulation technologies, enabling students to experience realistic combat scenarios much earlier. These technologies also make it possible to link aircraft with ground-based simulators and simulate complex joint missions involving both airborne and ground-based pilots operating in virtual threat and target environments. This reduces the required number of actual flight hours, generating significant savings in operating costs. However, sufficient flight time remains essential to effective pilot development, which is why customers increasingly seek platforms with low acquisition and operational costs. Our L-39 Skyfox is an exceptionally well-positioned aircraft in this respect — offered with a comprehensive ground-based training system and attracting great interest thanks to its advanced technology and affordability.
How are customer expectations changing regarding the acquisition of training aircraft, and how is Aero adapting its commercial strategy?
Customers are focused on affordable solutions and efficient budget utilization. Due to the high costs of modern combat platforms, they seek training systems that allow them to redirect resources toward acquiring and operating more advanced combat aircraft. Another strong trend is the need to accelerate the training process and produce more pilots in less time — in other words, “more and sooner.” Aero addresses this by offering a well performing, reliable jet training aircraft coupled with a full suite of simulators and training software, eliminating the need for expensive twin-engine, trans-sonic platforms for training.
Moreover, customers expect training systems to help maintain or rebuild comprehensive tactical capabilities. Aero responds to the ongoing trend of “downgrading” tactical preparation — a result of financial or capacity constraints — by offering realistic simulation of advanced combat scenarios through the Skyfox platform. This enables pilots to prepare for fifth-generation operational environments even in early training phases.
What training systems does Aero currently offer its customers?
Aero provides a comprehensive training system, including aircraft capable of delivering full-spectrum flight and tactical instruction. We offer virtual training environments, simulated radar, and datalink-enabled connectivity between aircraft. This is complemented by a full ground-based training system, from basic to advanced simulators — such as those delivered to the Flight Training Centre in Pardubice or to Hungary in cooperation with VR Group. Aero is also developing the integration of live aircraft with simulators to create a so-called “Live Virtual Constructive” environment. This technology will soon be introduced to our customers, who have already expressed significant interest.
Another major advantage of the L-39 Skyfox is its ability to support real weapons training. The aircraft is built with up to five hardpoints, which can already accommodate a wide range of both training and live weapons. Aero has long-standing experience integrating weapons systems from various manufacturers, which is highly attractive for our customers around the world.
Which regions are currently strategic for Aero, and what steps are being taken to strengthen your market position?
We primarily focus on replacing legacy L-39 aircraft in Eastern Europe, Africa, and Asia. However, we are increasingly penetrating markets in Western Europe and NATO countries, where customers value the cost-effectiveness of our solution and are often surprised not only by the Skyfox’s flight performance but also by its advanced technological capabilities. Thanks to this combination, we can train pilots to nearly the same level as more powerful platforms, but at a significantly lower cost. I would confidently say that today we can cover 95% of a full pilot training syllabus for fourth- and fifth-generation aircraft at just 50% of the cost compared to supersonic training platforms.
Which contracts could most significantly influence the future of the Skyfox platform?
A key strategic objective is to expand the Skyfox fleet at the CLV in Pardubice to a total of twelve aircraft — a move that reflects growing demand from the Czech Armed Forces and NATO. We are also pursuing a contract with Slovakia and working on major export opportunities in Africa, Eastern Europe, and Southeast Asia. A top priority is to establish a presence in one of NATO’s existing training centers in Western Europe or, possibly, in the US.
Are there ongoing campaigns or investments to expand production capacity and adopt new technologies?
Yes, we are both technologically and financially prepared to increase our production from the current 12 aircraft per year to 18, in response to growing demand. We are also modernizing our manufacturing processes across all programs, including expanding cooperation with Embraer and launching a new partnership with Lockheed Martin on the development of reconnaissance pods for various platforms.
What is the development potential of the Skyfox over the next five years?
We are preparing a new avionics upgrade that will bring the cockpit even closer to the experience of flying fifth-generation aircraft. In cooperation with Hungary and Saab, we are working on a “Gripenization” of the Skyfox cockpit to ease the transition for pilots moving to the Gripen. We also plan to expand the aircraft’s armament and sensor capabilities — including electro-optical systems, radar, and jammers — which will enhance operational flexibility without requiring major structural modifications.
What role should Aero play within the European defense industry?
Aero is already a cornerstone of the Czech aerospace sector, a major regional employer, and the holder of unique aerospace expertise within the country. However, we believe Aero should also be recognized as a strategic enterprise for the entire European Union. We are one of only two manufacturers in Europe capable of designing, developing, producing, and supporting a modern jet training aircraft end-to-end. We offer a proven platform that is globally competitive and uniquely positioned in the European context — alongside Leonardo’s aircraft.
We already supply major players around the world and are fully prepared to participate in the development of future European platforms, whether through the European Defence Fund or bilateral partnerships. From a geopolitical perspective, Aero plays a vital role in maintaining influence and strategic ties in key regions — especially in Africa and Asia — where we face increasing pressure and competition from countries like Russia and China. Our ambition is to be recognized as the most efficient European training and tactical platform for military pilots.
