The Mirage fighter aircraft, known for its agility and performance, has several variants, and the maximum vertical speed it can achieve depends on the specific model and its engine capabilities. However, providing specific real-world performance data for all possible Mirage variants is beyond my capabilities as i'm not into that for quite a while.
Generally, fighter aircraft like the Mirage are designed for high-performance maneuvers, and their maximum vertical climb rates can be quite impressive. They can climb vertically at rates exceeding 50,000 feet per minute (approximately 254 meters per second) in some cases.
To get the most accurate and up-to-date information on the maximum vertical speed of a particular Mirage fighter variant, it is best to refer to official documents from the aircraft's manufacturer or consult with relevant aviation authorities. These specifications are subject to change with advancements in technology and modifications made to the aircraft.
