Leaving aside the recent debates surrounding the Embraer C-390, I believe that, with a longer-term perspective, a strategic gap that could completely change the rules of the game could be targeted: Boeing closed its C-17 Globemaster production line years ago, and currently, the Western world cannot purchase a brand-new "Heavy Strategic Transport Aircraft (60+ Tons)" capable of transporting, for example, main battle tanks in one piece over intercontinental ranges.
While the Airbus A400M is excellent at the tactical level, its 37-ton capacity attempts to meet the heavy logistics needs of modern armies. However, to close this enormous monopoly gap in the global market, I envision a brand-new "Big Brother" project that references the C-390's tactical jet cargo architecture, fly-by-wire and ramp engineering, but is redesigned with four engines and a wide body.
The only alternative bloc that could realize such a vision in the Western aviation world by breaking the Airbus and Boeing monopoly is a partnership between Türkiye, Brazil, and the UK. Türkiye and Brazil, sharing the industrial risk 40-40, could be the main engine of the project. While Brazil (Embraer) is bringing its aviation expertise to the table, Türkiye can integrate TUSAŞ's existing airframe design experience from the A400M consortium, its deepening aero-structural manufacturing capabilities with KAAN and HÜRJET, in addition to its civil market experience; and ASELSAN/HAVELSAN's avionics and mission computer capabilities. The UK, meanwhile, can adapt Rolls-Royce's proven Trent series civil wide-body engines to military standards, providing the 40,000+ lbf thrust per engine required for the aircraft, as well as system engineering consultancy. Furthermore, a "launch customer" order of 14-20 aircraft from the Turkish Armed Forces (TSK), expanding its overseas operational footprint, could provide the initial financial impetus for this project.
On the civilian aviation side, the withdrawal of massive industrial cargo aircraft like the Antonov An-124 and Il-76 from the global market after the Russia-Ukraine war has created a serious shortage of oversized cargo aircraft in civil logistics. A "Civil Freighter" version of this aircraft, stripped of military systems, could quickly find its place in the fleets of global giants like Turkish Cargo. This "dual-use" platform, achievable with an R&D budget of approximately 8-10 billion dollars and a realistic 10-year timeline, would both transform the Turkish Armed Forces into a global logistics power and elevate our defense industry to the world's top league.
Could the idea of a tripartite alliance to fill this strategic void, desperately sought by the Western world, Western aviation-related markets, and armed forces, be realized without being hampered by geopolitical obstacles... This is truly one of the dreams that has been on my mind for some time.
