An airborne E-3G Sentry, operated by the Airborne Warning and Control System, or AWACS, Combined Test Force updated its electronic support measures, or ESM, database in flight over central Texas with a file transmitted from its reprogramming center at Eglin Air Force Base, Florida, using an existing beyond line-of-site satellite communications system.
The E-3G collected EW information using its existing ESM system and transmitted the in-flight recorded data to the 36th Electronic Warfare Squadron at Eglin AFB, Florida, using its satellite communications system. This test was conducted by 605th Test and Evaluation Squadron, Detachment 1, at Tinker AFB, Oklahoma, aligning with their mission to field innovation and develop tactics for the AWACS community.
"While most airborne EW systems provide self-protection, the primary purpose of the E-3G's ESM system is to provide situational awareness, combat identification, and threat warning for the rest of the assets in theater. Modern advanced radars are increasingly digital and can adapt faster than ever before, and the mission data update process needs to adapt along with it," said Maj. Jesse Snook, 605th TES, Det1 air battle manager.
Snook continued, "The E-3G has demonstrated its ability to exchange near real-time electronic warfare information with the experts on the ground and feed that information back into the fight immediately."
Within an hour, the 36th EWS processed and analyzed the E-3G's data, corrected deficiencies observed in the data, and transmitted the updated file back to the E-3G for immediate loading during the mission. The in-air update and in-air flight data transmissions were firsts for the E-3G. In addition, the concept referred to as Airborne Cooperative EW Integrated Reprogrammable Exchange, or ACEWIRE, was devised as a first step to accelerating antiquated reprogramming processes for the E-3G and the assets under its control.
