Turkey’s expanding missile ambitions are reshaping the Middle East power balance as U.S.-Iran tensions intensify. Ankara plans a first-ever 2026 test of Roketsan’s new 300 ER air-launched ballistic missile, giving Turkish F-16s a supersonic strike reach of more than 500 kilometers. At the same time, Turkey is signaling diplomatic support for Iran’s sovereignty and warning that pushing Iran’s missile program into nuclear negotiations could trigger another devastating regional war. With Israel pressing Washington for tougher terms and talks in Oman ending inconclusively, the region faces a dangerous new escalation frontier.
