The video circulating from Mashhad depicts Islamic Republic of Iran Air Force (IRIAF) fighter aircraft—variously identified as F-5, Kowsar, and Saeqeh types—conducting low-level patrol or flyover operations above a major funeral procession. These three aircraft designations are closely linked in Iran's military aviation lineage: the F-5 refers to the Northrop F-5E/F Tiger II, acquired by Iran in significant numbers during the Shah's rule in the 1970s and still operated today despite the airframes being more than four decades old. The Kowsar and Saeqeh are Iranian-developed derivatives built domestically by Iran Aircraft Manufacturing Industrial Company (HESA), leveraging reverse-engineered F-5 technology and airframe knowledge accumulated over decades of sanctions-driven self-sufficiency. The Saeqeh is distinguished by its twin vertical tail configuration, a modification from the original F-5's single-tail design, while the Kowsar is marketed as a more modernized single-seat light fighter with updated avionics.
For working pilots, particularly those with military or government-contract backgrounds, this kind of mission profile—armed aircraft conducting security patrol over a state funeral or mass public gathering—represents a specialized category of low-altitude, high-visibility flying that carries significant operational risk. Flying fighter aircraft at low level over dense urban crowds requires precise altitude and airspeed control, careful coordination with any temporary flight restrictions or ground security assets, and heightened situational awareness given the presence of large numbers of people, structures, and potential electronic or physical hazards near the flight path. These flights also serve a deterrent and symbolic function, projecting state authority and continuity during a moment of national significance, a practice seen in various forms across many countries during state funerals, though rarely executed with 1960s/70s-vintage fighter airframes still in frontline ceremonial and defensive roles.
The continued reliance on F-5-derived airframes decades after their original production ceased illustrates the broader trend of Iran's aviation sector operating under prolonged international sanctions and arms embargoes. Unable to procure modern Western or even most Russian and Chinese fighter platforms in quantity, Iran has invested heavily in domestic reverse-engineering and incremental upgrade programs to keep aging Cold War-era fleets operationally relevant. This is a notable case study for aviation professionals and analysts tracking how sanctioned states sustain airpower capability: extending airframe service life well beyond typical retirement windows through domestic manufacturing, avionics upgrades, and structural refurbishment programs, rather than fleet replacement.
More broadly, this event underscores how military aviation continues to serve ceremonial, state-security, and psychological functions well beyond combat operations, a dynamic relevant to corporate and business aviation operators who may need to navigate temporary airspace restrictions, NOTAMs, or heightened security postures when operating in or near regions experiencing major political transitions. Pilots planning international operations, especially those with routes touching Iranian airspace or nearby FIRs, should remain attentive to how politically significant events of this nature can trigger sudden airspace closures, military activity notices, or diplomatic tensions that affect overflight permissions and route planning in the broader Middle East corridor.
