It had a maximum speed of over 500 knots (925 km/h) and a range of around 1,500 nautical miles (2,780 km), depending on payload and fuel configuration. It was powered by two General Electric CJ610 turbojet engines, providing a thrust output of around 2,850 pounds each.
Several variants of the Learjet 25 were produced, including the Learjet 25A, 25B, 25C, and 25D. These variants featured various improvements and modifications, such as increased fuel capacity, upgraded avionics, and improved performance. The Learjet 25D was particularly notable for its extended range and upgraded systems.
The Learjet 25 played a significant role in popularizing the concept of the business jet, offering executives and high-net-worth individuals a fast and convenient means of air travel. Its success paved the way for further developments in the Learjet series and contributed to the growth of the business aviation industry.
