Bangladesh Air Force F-7 BGI Crash: A Closer Look at the Chinese MiG-21 Variant
On July 21, 2025, a tragic incident shook Dhaka, Bangladesh, when a Bangladesh Air Force (BAF) F-7 BGI training jet crashed into Milestone School and College in the Uttara area, claiming at least 19 lives, including the pilot, Flight Lieutenant Mohammed Toukir Islam, and injuring over 100 people, many of them students. The aircraft, a Chinese-made F-7 BGI, is a modernized variant of the Soviet-era MiG-21, and this devastating crash has reignited scrutiny over the reliability of Chinese-built military aircraft. Here’s what we know about the F-7 BGI and the circumstances surrounding the incident.
The F-7 BGI: A Chinese Evolution of the MiG-21
The F-7 BGI, developed by China’s Chengdu Aircraft Corporation, is an advanced variant of the Chengdu J-7 series, which itself is a licensed and reverse-engineered version of the Soviet Mikoyan-Gurevich MiG-21. The MiG-21, often referred to as the "Grandpa fighter jet," was one of the most mass-produced fighter aircraft in history, known for its speed and affordability but also for its high accident rate due to design limitations. The F-7 BGI, tailored specifically for the Bangladesh Air Force, represents a modernized take on this aging platform, incorporating upgrades to meet contemporary needs while remaining cost-effective.
Key Features of the F-7 BGI
- Top Speed: Mach 2.2, enabling rapid response in short-range missions.
- Weapons: Equipped with five hardpoints for air-to-air missiles (e.g., PL-5, PL-7, possibly PL-9), laser- and GPS-guided bombs, and up to 3,000 lbs of bombs or unguided rocket pods.
- Radar System: Features the KLJ-6F fire-control radar, capable of tracking six targets and engaging two simultaneously at a range of over 86 km.
- Cockpit: Boasts a fully digital glass cockpit with three multifunctional heads-up displays (HUDs) and hands-on throttle-and-stick (HOTAS) controls for enhanced pilot situational awareness.
- Airframe: Based on the J-7G2 design with a double-delta wing, improving lift, reducing stall risk, and enhancing maneuverability compared to earlier MiG-21 variants.
- Service Ceiling: 17,500 meters (57,420 feet).
- G-Load Tolerance: +8 g / -3 g, supporting agile combat maneuvers.
- Thrust: 82 kN with afterburner, providing robust performance for a lightweight fighter.
- Additional Capabilities: Can carry C-704 anti-ship missiles for maritime strike missions and supports helmet-mounted sights for improved target acquisition.
Despite these upgrades, the F-7 BGI lacks beyond-visual-range (BVR) missile capability, limiting its effectiveness in modern air combat. It is primarily used for short-range aerial combat, light attack roles, and pilot training, making it a budget-friendly option for air forces like Bangladesh’s.
The Crash: What Happened?
The F-7 BGI involved in the crash took off from a nearby airbase at 1:06 PM local time on a routine training mission. Approximately 12-24 minutes later, it plummeted into the Milestone School and College campus in Dhaka’s Diabari area, striking a two-story building, possibly the canteen or junior section, during lunchtime when many students were present. The impact caused a massive fire, with thick smoke and flames visible in footage from the scene. The crash killed at least 19 people, including 16 children, two teachers, and the pilot, and injured over 100 others, with many sustaining severe burns. At least eight victims were reported in critical condition.
According to the Inter-Services Public Relations (ISPR) department, the aircraft experienced a “technical malfunction” shortly after takeoff. The pilot, Flight Lieutenant Taukir Islam Sagar, reportedly attempted to steer the jet away from densely populated areas to minimize damage, but the aircraft ultimately crashed into the school. Rescue operations were swiftly launched, involving eight fire service units, Bangladesh Army personnel, air force helicopters, and two Border Guard Bangladesh platoons. Victims were rushed to the National Institute of Burn and Plastic Surgery and Combined Military Hospital, with calls for blood donations to support the injured.
Why the F-7 BGI? Bangladesh’s Acquisition and Use
Bangladesh acquired 16 F-7 BGI jets between 2011 and 2013 as part of an effort to modernize its aging air fleet. In 2022, China reportedly donated an additional 36 units, expanding the BAF’s F-7 fleet. Despite being considered outdated by global standards, the F-7 BGI remains in service due to its low cost and reliability for training and light combat duties. The BAF operates several F-7 variants, including FT-7MB Airguards and F-7BG interceptors, alongside other aircraft like MiG-29s and FT-6s (based on the MiG-19).
The F-7 BGI’s affordability and tailored design made it attractive for Bangladesh, a nation with budget constraints. Its modern avionics and improved maneuverability, thanks to the double-delta wing, offer advantages over older MiG-21 variants. However, the aircraft’s roots in the 1960s-era MiG-21 design mean it inherits some limitations, including narrow safety margins and high pilot skill requirements, especially during low-altitude training missions.
Renewed Scrutiny on Chinese-Made Aircraft
This crash marks the second F-7 incident for the BAF in 2025, following a crash in the Bay of Bengal in June. Previous incidents include a 2018 crash in Tangail’s Madhupur region, highlighting a pattern of operational failures. The F-7’s reputation as a “Flying Coffin,” inherited from the MiG-21, is compounded by reported issues with Chinese manufacturing, such as inconsistent quality control, defective components, and poor after-sales maintenance support. A similar crash involving a Myanmar Air Force F-7 in June 2025, which killed the pilot and five villagers, further raised concerns about the reliability of Chinese-built jets.
Posts on X have echoed these sentiments, with users questioning the safety of Chinese aircraft and pointing to broader issues with China’s defense exports. For instance, during the India-Pakistan conflict following Operation Sindoor, Pakistan’s F-7s reportedly suffered mechanical failures, and Chinese PL-15 missiles misfired, underscoring doubts about their efficacy in high-stakes scenarios.
Investigation and Aftermath
Bangladesh’s interim government, led by Muhammad Yunus, has declared a national day of mourning on July 22, 2025, with flags flown at half-mast. Yunus expressed “deep grief and sorrow,” calling the loss “irreparable” and directing authorities to prioritize medical treatment and investigate the crash’s cause. A high-level BAF investigation committee is examining whether the incident resulted from technical failure, pilot error, or other factors. Ousted Prime Minister Sheikh Hasina and opposition leader Tarique Rahman have also called for comprehensive support and rescue efforts.
The tragedy has sparked debate about the safety of low-flying military aircraft over densely populated areas like Dhaka and the continued use of aging platforms like the F-7 BGI. As rescue operations continue and the nation grieves, the crash underscores the human cost of military accidents and the challenges of balancing cost-effective procurement with operational safety.
Conclusion
The F-7 BGI, while an upgraded and cost-effective variant of the MiG-21, remains a product of an outdated design with inherent risks. Its role in the Bangladesh Air Force highlights the trade-offs of affordability versus reliability, particularly for training missions in urban areas. As investigations proceed, this tragic crash may prompt Bangladesh and other nations to reassess their reliance on Chinese-made aircraft and prioritize safety in military aviation.
