During the 1990s the same F-15 airframe (USAF S/N 71-0290) was further modified (canards and nozzles were retained) for the ACTIVE (Advanced Control Technology for Integrated VEhicles) program in which Pitch/Yaw Balance Beam Nozzles (P/YBBN) and advanced control-logic programming were investigated.
 In the ACTIVE configuration it was also used for the LANCETS (lift and nozzle change effects on tail shock) program, in which computed supersonic shockwave parameters were compared to those measured in flight.
 The LANCETS flight tests ended in December 2008.
 F-15 ACTIVE lasted from 1993–99.

The aircraft would later be used in the F-15 IFCS (Intelligent Flight Control System) program from 1999 to 2008.
The plane was also used for the Space-Based Range Demonstration and Certification project under the Exploration Communications and Navigation Systems program (SBRDC/ECANS) from 2006 to 2007, High Stability Engine Control (HISTEC) program and High-Speed Research Acoustics in 1997.
