Navy, Boeing Studying Block II Version of EA-18G Growler Electronic Attack Aircraft

ARLINGTON,
Va. — Boeing is in the wrap-up stages of a trade study and architecture
assessment of an upgrade — called Block II — to the Navy’s EA-18G Growler
electronic attack aircraft. The upgrade is an effort to enable the EA-18G to
keep up with the dynamic electronic warfare threats.

“It makes
sense that we would take something that was designed in the ‘90s and now
enhance it to be relevant for decades to come,” said Jennifer Tebo, Boeing’s
director of development for the F/A-18 and EA-18G, speaking to reporters May 7
at the Navy League’s Sea-Air-Space exposition.

“It makes sense that we would take something that was designed in the ’90s and now enhance it to be relevant for decades to come.”

“The current
thinking on that is that it is a retrofit program,” Tebo said. “There is no
official new-build Growler Block II. We will continue to work with the Navy to
determine what those needs are, how we might incorporate them into a new build.
We’re thinking of a retrofit program that would deliver capability in the 2025 timeframe.
We’ve already starting work in earnest and early this year got initial funding
from the Navy to start moving to the [System Functional Requirements] phase by the
end of this year to deliver that capability on time.”

Tebo said
that the Growler Block II enhancements will include some of the upgrades of the
Super Hornet Block III program, plus “enhanced sensitivity through the
modernization of the sensors on the platform. … It’s about adaptive and
distributive processing, having big computers to process and be able to react
to the threats that are out there today and into the future.”

“It’s also
about enhancing the crew-vehicle interface,” Tebo added. “As the Growler crews
get more and more information into the cockpit, they’re going to need a way to
reduce the workload to be able to digest and use it effectively. All of that is
accomplished through software-defined radios that are enabled through a
flexible and adaptable hardware architecture.”

Tebo said the
infrastructure and the architecture will “allow us to continually evolve
capability as the threat dynamic changes. The life of the Growler is very, very
long. We’re setting this up for the Navy to be able to continue add capability
rapidly to the Growler.

“It’s been a joint
effort and it will evolve as we pin down the requirements,” she said.

She confirmed
that the Next-Generation Jammer and the mid-band and low-band jammers “are
considered part of the future of the Growler and Growler Block II.”

Boeing’s
concept of Block II includes the conformal fuel tanks being included in the
Super Hornet Block III, but “the Navy will have to decide,” she said.

Also to be
decided is whether the Growler will go through a service life-extension
program. The Super Hornet fleet is going through a service-life extension from
6,000 flight hours to 10,000 hours.

“That is to be decided,”
Tebo said. “The Growler has a 7,500-hour service life compared to 6,000-hour
life of the Super Hornet. [The Growler] has not finished its service-life
assessment program yet.”
