What is the Chinese-made F-7 jet that crashed into Bangladesh school?

A Bangladesh Air Force fighter jet on a routine training mission crashed into a college and school campus in the capital Dhaka on Monday (21 July) after what the military said was a mechanical failure.

At least 31 people were killed, most of them children.

Here's what we know about the F-7 BGI jet that went down:

What are F-7/J-7 fighter jets?

The F-7 BGI, which crashed soon after take-off, is a lightweight fighter jet, the final and most advanced version of China's Chengdu J-7/F-7 family, according to Jane's Information Group.

The Chengdu J-7 is the licence-built version of the Soviet era MiG-21 and is used for training and limited combat roles. The F-7 is the export variant of J-7.

The South Asian country's air force has operated F-7 variants since the 1980s. Dhaka signed a contract for 16 BGI version aircraft in 2011 and deliveries were completed by 2013 - the final batch of the manufactured jets.

Production of the jets

China manufactured the jets from 1965 to 2013, making it one of the longest-running fighter production lines there. Due to its affordability, the jet was widely exported, especially to developing nations.

The J-7 was fully decommissioned from the Chinese military by the end of 2023 but several countries still use the export variant.

Widespread usage of F-7

Pakistan, Bangladesh, Nigeria, Egypt, Iran and North Korea are among the countries that have used or still use variants of the F-7.

Pakistan is the largest operator of F-7 aircraft and has 66 of them, according to the London-based International Institute of Strategic Studies.

Pakistan also has one of China's most advanced warplanes, the J-10, and used it to launch air-to-air missiles to bring down at least two Indian fighter jets during the recent conflict between the two countries.

Past incidents involving the jets
