ASI received a contract from NAWCTSD to modify the five EA-6B trainers located at NAS Whidbey Island and MCAS Cherry Point: Device 2F119A Weapon Systems Trainer (WST), two Device 2F143 Operational Flight/Navigation Trainers (OF/NT), and two Device 15E22C Team Tactics Trainers (TTT). These trainers make extensive use of unmodified aircraft equipment and operational flight software.

The contract included computer rehost of all five trainers, from a mix of Encore 32/67, 32/77, and 32/97 models to Encore RSX computers.

It included incorporation of an Electronic Flight Instrument System (EFIS) in place of simulated flight instruments, incorporation of EFIS repeaters at the Instructor/Operator Station (IOS), incorporation of the Control Display Navigation Unit (CDNU), simulation of VOR/ILS, and simulation of a Global Positioning System (GPS) in Device 2F119A and both 2F143 Devices. It included upgrading the single-board computer driving the MIL-STD-1553 data bus system on the 15E22C Devices, and upgrading the visual system image generator on the 2F143 Devices. It also included integrating Device 2F143 with Device 15E22C at each site so that they can operate either independently of each other simultaneously, or jointly as a single WST. This necessitated replacement of the communication systems in all four trainers.
