context_page_description: The Honeywell/ITEC F124 is a low-bypass turbofan engine derived from the civilian Honeywell TFE731. The F125 is an afterburning version of the engine. The engine began development in the late 1970s for the Republic of China Air Force AIDC F-CK Indigenous Defence Fighter, and it first ran in 1979. The F124/F125 engine has since been proposed for use on other aircraft, such as the T-45 Goshawk and the SEPECAT Jaguar, and currently powers the Aero L-159 Alca and the Alenia Aermacchi M-346. The F124 has a rather unusual design for a two spool gas turbine engine, using both axial and centrifugal compressors in its high-pressure compressor. There are currently only three production variants of the engine, although several more have been proposed throughout its lifespan.
context_section_description: The afterburning F125 engine is being considered, as of 2009, by the Indian Air Force as a replacement for the Rolls-Royce Turbomeca Adour engines in their SEPECAT Jaguar aircraft. The new engine would be both lighter and more powerful. It was successfully demonstrated in 2007. This proposal of Indian Air Force to up-engine its fleet of SEPECAT Jaguar ground attack aircraft stalled after a decade in August 2019 owing to the high cost involved. Jane's quoted that Honeywell quoted a price of USD2.4 billion for 180 F-125IN turbofan engines as replacements for the Rolls-Royce Turbomeca Adour Mk 811 powerpacks originally installed in the Jaguars.
