In 1988, Allison Engine Company (then owned by General Motors) and Rolls-Royce plc began joint studies of a {{cvt|33|kN}} RB580 to power the proposed Short Brothers FJX regional jet, combining the T406 core with a Rolls-Royce low-pressure spool.

By late 1989, amid growing importance of the Rolls-Royce Trent engine and uncertainty over the Short Brothers project, Rolls-Royce quit. Allison Engine Company pursued the engine alone, revising the design as a new wide-chord snubberless (or clapperless) titanium fan and low-pressure turbine.

On March 23, 1990, Allison's GMA 3007 was selected to power the Embraer EMB-145 regional jet. In September 1990, it was selected for the Cessna Citation X.

The engine was first ground tested in mid-1991. On August 21, 1992, the engine had its first test flight on a Cessna Citation VII testbed aircraft.

In 1995, Rolls-Royce bought Allison Engine Company and the engine had its first flight on the EMB-145.

The Citation X AE3007C, producing {{cvt|28.655|kN|lbf}}, was certificated by the FAA in February 1995; while the

EMB-145 AE3007A, producing {{cvt|39|kN|lbf}}, was certificated in mid-1996.{{cite news |url= https://www.flightglobal.com/news/articles/baby-big-fan-17332/ |title= Baby big fan |author= Guy Norris |work= Flight International |date= 10 April 1996}}

In 1995, Teledyne Ryan selected the AE3007H for the Tier II+ unmanned surveillance aircraft (now the Northrop Grumman RQ-4 Global Hawk), which required long-endurance at up to {{cvt|70,000|ft|lk=in}}.

It was tested at these altitudes in February 1996 at the Arnold Engineering Development Center in Tennessee and the first was delivered in May 1996.

More than 3,400 engines have been delivered.{{cite news |url= https://www.rolls-royce.com/products-and-services/defence-aerospace/transport-tanker-patrol-and-tactical/ae-3007.aspx |title= AE 3007 for Transport, Tanker, Patrol & Tactical |publisher= Rolls-Royce}}

In 2014, 2,976 civil engines were installed.{{cite web |url= https://www.rolls-royce.com/~/media/Files/R/Rolls-Royce/documents/investors/results/2017-half-year-civil-engine-deliveries-installed-base-and-thrust.pdf |title= Civil engine deliveries installed base |date= 2017 |publisher= Rolls-Royce}}

In 2017, the AE 3007 in the ERJ family had flown over 53 million hours and over 44 million cycles.{{cite news |url= https://www.rolls-royce.com/~/media/Files/R/Rolls-Royce/documents/civil-aerospace-downloads/AE-3007-infographic-24-10-17.pdf |title= AE 3007 infographic |publisher= Rolls-Royce |date= 24 Oct 2017}}

It was flown for more than 60 million hours.{{cite news |url= http://www.rolls-royce.com/products-and-services/civil-aerospace/business-aviation/ae-3007.aspx |title= AE 3007 for business aviation |publisher= Rolls-Royce}}

The engine is manufactured at the Rolls-Royce North America engine plant in Indianapolis, Indiana.{{cite web |url= https://myaeroengine.com/OnWingCare/LINKS/AE3007_tcm92-5744.pdf |title= Rolls-Royce AE3007: Power for Embraer and Cessna |publisher= Rolls-Royce}}

The AE 3007 is a direct drive turbofan engine with a single stage fan, a 14-stage axial compressor with 6 stages of variable vanes including inlet guide vanes, an annular combustor, a two-stage high pressure turbine and a 3-stage low pressure turbine.

The accessory gearbox is mounted at its bottom and two single channel FADEC units are mounted in the aircraft.

It has fore and aft mounting provisions for underwing pylon or aft fuselage installation.{{cite web |url= https://www.easa.europa.eu/system/files/dfu/AE3007_TCDS%20EASA.IM_.E.044%20issue%2005_20150522_1.0.pdf |title= Type Certificate Data Sheet No. IM.E.044 for AE 3007 Series Engines |date= 22 May 2015 |publisher= EASA}} The AE 3007 has a thrust-specific fuel consumption (TSFC) of {{cvt|0.36|tsfc}} at static sea level takeoff and {{cvt|0.65|tsfc}} at a cruise speed of Mach 0.8 and altitude of {{cvt|10,670|m|order=flip}}.{{cite book |author=Élodie Roux |title=Turbofan and turbojet engines: Database handbook |url={{GBurl|_5vA_5XK33sC|p=50}} |page=50 |year=2007 |publisher=Elodie Roux |isbn=9782952938013 |oclc=879328119}} The engine's A variant was designed to produce a cruise thrust of {{cvt|1,420|lbf|kN kgf lbf|order=out}} at Mach 0.8 and {{cvt|41,000|ft}} altitude.{{cite magazine |magazine=Flying |issn=0015-4806 |title=Citation X is a 10 |url={{GBurl|1P3-28GOf-MC|p=106}} |publication-date=June 1991 |given=Nigel |surname=Moll |pages=106–108, 110, 114}}
