In 2012, GE was chosen to continue its ADVENT work into the AETD program. GE and Pratt & Whitney were selected over Rolls-Royce to continue the AETD program to mature fuel-efficient, high-thrust powerplants. Operational testing of the engine was expected to begin in 2013. Under AETD, GE had set

October 2009, Rolls-Royce was awarded the Phase II contract to continue component testing and integrate the developed technologies into a technology demonstrator engine. GE Aviation was also awarded funds to continue development of their technology demonstration core, which was unexpected as the

Generation Adaptive Propulsion (NGAP) program. The competing designs for NGAP are the

The objective of ADVENT is to develop an engine that is optimized for several design points, rather than the traditional single point. Instead of having an engine that is designed solely for high speed (like many current fighter engines are) or for high

Adaptive Engine Transition Program (AETP) was launched with the goal of developing and testing adaptive engines for the future sixth generation fighter programs, Penetrating Counter Air (PCA) or

In 2017, Pratt wrapped up tests of their three stream engine with a F135 core, which may be used on the
