NEW DELHI: The defence ministry has withdrawn its tender for re-engining the Indian Air Force's Jaguar combat jets after one of the two contenders opted out, a leading defence journal says. The Request for Proposal (RfP), as the tender is known in technical parlance, was issued to Honeywell, which had offered its F-125IN engine and Rolls Royce, whose Adour-811 has powered the Jaguar's since their induction in the IAF in the late 1970s, India Strategic defence magazine reports in its current edition. The IAF would now have to submit a fresh proposal to the defence ministry, which will then issue another tender. This process is expected to take about a year. The economic times report.
