EA-6B Weapon Systems Trainers

ASI received a contract from NAWCTSD in September 1995 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. This contract was completed in October 1998.

ASI received another contract from NAWCTSD in August 1997 to upgrade the Device 2F143 and 15E22C trainers to EA-6B Block 89A configuration and to replace the Digital Radar Landmass Simulator (DRLMS) in Device 2F119A. The contract also included modification of the simulated electronic warfare radar receiver system and jammers to include new bands of coverage, modeling of new threats, and incorporation of the USQ-113/Connectivity Upgrade on the 2F119A and 15E22C Devices. NAWCTSD accepted ASI’s proposal to replace the existing hardware-intensive electronic environment simulation on Device 2F119A and Devices 15E22C with a digital environment generator, the Combat Electromagnetic Environment Simulator (CEESIM), resulting in greater simplicity of use, improved reliability and maintainability, and greater fidelity for the trainers. The Block 89A upgrade included incorporation of a dual MIL-STD-1553 data bus architecture extending across both the 2F143 and 15E22C trainers, extending the CDNU functionality to make it primary Navigation bus controller, and making the Central Mission Computer (CMC) the back-up Navigation bus controller and the primary EW bus controller. It also included replacement of the GPS with the Embedded GPS/INS (EGI) system, plus addition of enhanced communication capability including USQ-113, connectivity, the AN/ARC-210 radio system, and Advanced Narrow Band Digital Voice. ASI’s accomplishments included development of an Operational Trainer Program (OTP) for the CDNUs installed in the 2F143 Devices to enable them to tolerate freezing, repositioning, and slewing of the simulated aircraft. All trainer modifications were completed in September 2001.

ASI also received a contract from Lockheed-Martin Information Systems (LMIS) in October 2000 to participate as a key member of the Integrated Product Team developing the specifications for a completely new suite of trainers for the EA-6B aircraft. LMIS sought out ASI’s participation in this effort because of our extensive experience with the current EA-6B trainers. The specification development activity was completed in April 2001.
