WASHINGTON — The airplane that may at some point be the Air Pressure’s subsequent digital warfare plane, the EC-37B Compass Name, has made its first flight and the contractor dealing with this system says it’s on observe to be delivered to the service for testing subsequent yr.
The present model of the Compass Name, the EC-130H, performed a lesser-known — however important — position within the final 20 years of conflict within the Center East area, jamming the communications and bomb transmissions of militant teams such because the Taliban and Islamic State. However these decades-old air frames — a few of which date again to the Vietnam Conflict period — are growing old and sorely want changing.
The Air Pressure in 2017 awarded a contract to L3Harris Applied sciences to hold out the Compass Name’s crossdeck program, which transplants the digital warfare tools from the legacy EC-130Hs into new Gulfstream G550 enterprise jets. BAE Methods handles the digital warfare parts of the Compass Name.
L3Harris has carried out roughly a dozen check flights of its first Compass Name on the Gulfstream facility in Savannah, Georgia, Luke Savoie, president of the corporate’s aviation companies sector, mentioned in a Monday interview. The preliminary flight of the brand new Compass Name befell Aug. 25.
These flight checks — together with high-altitude flights at round 40,000 toes and different checks to ensure it might function in low temperatures — are supposed to certify the structural modifications L3Harris made to the plane to accommodate the huge quantities of digital tools it should carry, Savoie mentioned.
“It’s about waking the plane up after its modification, earlier than it will get into its subsequent section,” Savoie mentioned.

The Air Pressure presently flies G550s below the designation C-37B to move high-ranking authorities or Protection Division officers around the globe.
However as a substitute of luxurious cabins and plush seating for VIPs, the EC-37B might be filled with a broad array of electronics meant to sow confusion in enemy ranks.
In a 2017 interview with Air Pressure Occasions, the previous commander of the forty third Expeditionary Digital Fight Squadron mentioned the Compass Name’s job within the conflict in opposition to ISIS was to jam their communications and radar every day.
“The underside line is, when you can’t discuss, you possibly can’t battle,” then-Lt. Col. Josh Koslov, who’s now a colonel, mentioned on the time. “Our job is to create large confusion within the [ISIS] community.”

Savoie mentioned the EC-37B, when full, will have the ability to fly a lot increased and sooner than the older Compass Calls. The Air Pressure mentioned the EC-130H has a ceiling of 25,000 toes and might hit 300 miles per hour. However Savoie mentioned G550s can usually fly into the mid-40,000 foot vary and almost twice that velocity, increasing the vary of what its EW methods can goal.
“Twice the altitude is twice the horizon, you can see the world you can have an effect on and work together with,” Savoie mentioned. “It’s all about altitude and velocity.”
However as a result of the EC-37B is predicated on the commercially obtainable G550, and never a military-specific airframe, Savoie mentioned it’s anticipated to be simpler for the Air Pressure to keep up. The brand new Compass Name will have the ability to be maintained primarily within the discipline, he mentioned, with out the necessity for important depot upkeep time just like the decades-old EC-130Hs require. This, he added, will imply much less plane downtime.
Flying the older EC-130Hs within the harsh and dusty Center East atmosphere for many years proved taxing. Maintainers wanted to frequently examine the airframes for structural weaknesses and be careful for issues with its wiring and engines. Sustaining the brand new digital warfare tools that had been added to the outdated planes — considered one of which first flew in 1964 — additionally was a big problem.
The modification to the G550s to make them into Compass Calls will happen in two phases, Savoie mentioned. The primary section, performed in Savannah, entails modifying the outside, together with increasing the plane’s facet panels, nostril, and tail and putting in radomes, exterior arrays and antennas. L3Harris can also be putting in the majority of the wiring harnesses, liquid cooling methods and energy distribution methods in that section.
Through the design course of, Savoie mentioned, L3Harris used as a blueprint the best way G550s had been beforehand modified into the Conformal Airborne Early Warning, or CAEW, plane flown by Israel and Singapore’s air forces. Following the CAEW design, as a substitute of making a brand new design, simplified the method and decreased threat, he mentioned.
The flight checks went easily, he mentioned, with no flutter issues or different points that may come up when modifying plane with distinctive shapes.
However when an plane is modified, components similar to the middle of gravity additionally change, he mentioned. So L3Harris had to make sure autopilot features and avionics, amongst different gadgets, had been responding to how the plane is presently formed and working appropriately.
“Clearly, everytime you make important outer mould line modifications to an plane, [there are] tweaks to the avionics, particularly superior methods like Gulfstream employs,” Savoie mentioned. “That’s what our flight check has confirmed out, that these modifications have been efficient.”
Within the second section, which is able to happen on the L3Harris facility in Waco, Texas, the corporate will set up mission-specific {hardware}, similar to crew consoles and stations. L3Harris already conducts depot upkeep for EC-130s in its Waco facility.
The digital warfare tools that might be put in within the new Compass Calls will partly be drawn from the legacy plane, and partly new tools, Savoie mentioned. Some components within the older plane wanted extra miniaturization; in different circumstances, parts had been out of date or outdated.
“We’re incorporating the DNA of the EC-130H — not simply the DNA, we’re doing organ transplants,” Savoie mentioned.
Over the EC-130H’s 20 years within the Center East, Savoie mentioned, the Air Pressure realized it wanted to be agile and shortly alter to deal with rising threats or counter new capabilities.
The EC-37B is meant to be equally agile, by making it straightforward so as to add new capabilities — possible with software program updates — when the necessity arises, he mentioned.
Savoie mentioned L3Harris’ first Compass Name, referred to as plane one, is anticipated to complete the primary section modifications this month. On the identical time, the corporate has began laying the groundwork for the second section by conducting preassemblies and making a mockup plane. The primary plane is anticipated to reach in Waco on the finish of October.
L3Harris is engaged on modifying six plane into EC-37Bs, Savoie mentioned, and the Air Pressure ultimately hopes to have 10 in its fleet.
L3Harris will end modifying the primary EC-37B in 2022 and ship it to the Air Pressure for its personal developmental check cycle by the top of subsequent yr, he mentioned. He declined to say when the next EC-37Bs may be delivered.
