Back in the mid/late 80s AvWeek had an article on an engine Allison was testing that was in the 30,000lb thrust range but supposedly smaller than an F100 (ISTR they said F404-size but it's been 20 yrs). At the time it got me thinking there would be three companies proposing engines for the ATF and then all of a sudden nothing. Never heard another word about any advanced Allision engine design until MUCH later when RATTLRS comes into being and lo and behold there is Allison in the thick of things. Any idea whatever happened to the fighter engine?

Keep in mind that Allison was another underperforming subsidiary of General Motors until Rolls-Royce finally took over. Allison traditionally dominated in the high and low ends of the turboprop/turboshaft market, but had a poor track record in the military turbojet/turbofan market. Even the TF-41 was far more problematic than the Spey it was based on. It is easy to imagine that a preliminary study might have taken place, but Allison lacked the resources and management to compete directly with P&W or even GE for a fighter engine contract.

Speaking of Allison, anyone does know what is the Allison Type 701 C ? (timeframe, late '50s, and judging from the plane it had to propel, a jet)
