9/12/2014 - HANSCOM AIR FORCE BASE, Mass. -- The
U.S. Air Force and NATO are undergoing a cooperative development effort
-- known as the DRAGON program -- to upgrade the cockpits of their E-3
Sentry Airborne Warning and Control System aircraft.
DRAGON stands for Diminishing Manufacturing Sources Replacement of
Avionics for Global Operations and Navigation. And just as its name
suggests, finding parts for the aging AWACS fleets is a main concern for
both the Air Force and NATO.
"As original equipment manufacturers discontinue support to 40-year-old
avionics, replacement parts are becoming harder and harder to come by,"
said Jennifer Pomphrett, DRAGON project manager.
Easily identified by its 30-foot rotating radar dome, E-3 AWACS use
on-board computers and radar to provide a detailed aerial picture of
airspace covering more than 200,000 miles in all directions.
The DRAGON program office, located at Hanscom Air Force Base, Mass., is
the driving force behind the replacement of non-sustainable, mainly
analog, equipment. Existing technology will be updated with commercially
available, digital avionics systems.
The flight deck modernization replaces most analog indicators with
modern digital multicolor graphical displays. In addition, nearly all of
the 1970s avionics are being replaced with updated airspace-compliant
subsystems. This modernization also allows for elimination of the
navigator, dropping the crew size from four to three, as well as adding a
Mode-5 Identification Friend or Foe capability.
All aircraft infrastructure such as engines, airframe and mission
systems will remain, but the upgraded E-3 flight deck will host a
plethora of new technology currently used by the commercial airline
industry.
Digital satellite-based communications; modern flight management system
suite architecture; and a digital cockpit that includes five glass
display screens will offer aircrews easy-to-use and customizable engine,
navigation and situational awareness data.
Other new capabilities will include a weather radar that can predict
wind shear, an Enhanced Ground Proximity Warning System, warnings,
cautions and advisories via an Engine Instrument and Crew Alert System
and a fully digital flight deck audio distribution system.
In addition to hard-to-find replacement parts, another reason for the
AWACS upgrade is due to changing national and international regulations
for civil airspace.
The International Civil Aviation Organizations has imposed new flight
mandates that need to be met by 2018. With the flight deck
modernization, both U.S. and NATO fleets will meet the mandates and will
have broader access to airspace.
"Unrestricted flight through preferred airspace takes the E-3 to the
fight when it needs to be there," said Sid Kimhan, DRAGON program
manager. In addition, "the shorter flying times provided by access to
preferred routes reduces costly wear and tear on the fleet and fuel
consumption."
The Air Force and NATO are progressing together through risk reduction
and engineering, manufacturing and development phases, but the
organizations will have separate contracts for the production,
deployment and operational stages.
"This cooperative effort is important because it leverages the 95
percent design commonality between the U.S. and NATO AWACS and promotes
interoperability, interchangeability, cost sharing and a common
sustainment and logistics pipeline," said Rob Stewart, DRAGON logistics
manager.
Boeing, which holds the current EMD contract, installed one digital
flight deck and avionics system onto the first NATO aircraft, N-1, and
will also install another system into an Air Force test aircraft, D-1,
in the coming months.
Ground testing for the NATO AWACS is slated for this month with an
anticipated first test flight scheduled for November. The Air Force
expects its 24 updated E-3s to be delivered by the fourth quarter of
fiscal year 2025.
"We're very pleased with the progress that's being made," said Lt. Col.
Brian Clifford, E-3 Operational Capabilities branch chief. "This
modernization will bring a whole new level of communication, navigation
and surveillance to the U.S. and NATO E-3 operational community."
