Northrop Grumman-Developed Multifunction Advanced Data Link Achieves Successful Flight Test Milestone for F-35 Program Fifth-Generation Data Link Allows Coordinated Tactics and Engagement in High-Threat Environments
"SAN DIEGO – April 23, 2013 –The Multifunction Advanced Data Link (MADL) waveform developed by Northrop Grumman Corporation was successfully demonstrated in a Lockheed Martin F-35 Lightning II joint strike fighter program flight test, validating an eight-year development effort to advance communication among fifth-generation aircraft.

MADL is a high-data-rate, directional communications link. It allows coordinated tactics and engagement to bring significant operational advantages to fifth-generation aircraft operating in high-threat environments. MADL is a key capability provided by Northrop Grumman's F-35 integrated communications, navigation and identification (CNI) avionics.

The F-35 CNI avionics flying onboard two Lockheed Martin F-35 aircraft established the MADL link between two airborne platforms for the first time. Data passed between aircraft via MADL was correlated with data from other F-35 sensors by Lockheed Martin's fusion system to form a simplified situational awareness picture on the cockpit displays.

"During the flight tests, MADL functioned reliably with excellent range at multiples of required specifications while demonstrating ability to network fifth-generation fighters," said Mike Twyman, vice president and general manager of the Defense Systems division for Northrop Grumman Information Systems. "This success is a significant achievement for the F-35 program and enabling joint aerial concept of operations."

The MADL flight test is an important element of Lockheed Martin's F-35 Block 2 software release, which provides advanced mission systems capability at Edwards Air Force Base, Calif., and other training and operational locations. At Edwards, MADL joined the CNI Link-16 and Variable Message Format network waveforms already in flight test on F-35 aircraft.

Northrop Grumman's integrated CNI system provides to F-35 pilots the equivalent capability of more than 27 avionics subsystems. By using its industry-leading software-defined radio technology, Northrop Grumman's design allows the simultaneous operation of multiple critical functions while greatly reducing size, weight and power demands on the advanced fighter. These functions include Identification Friend or Foe, automatic acquisition of fly-to points, and various voice and data communications, including MADL, which was approved by the U.S. Department of Defense Joint Requirements Oversight Council for use on all low-observable platforms...."

You missed a key announcement in there
"During the flight tests, MADL functioned reliably with excellent range at multiples of required specifications while demonstrating ability to network fifth-generation fighters," said Mike Twyman, vice president and general manager of the Defense Systems division for Northrop Grumman Information Systems.

It's good to see some "exceeded spec" news rather than "missed spec". :)

Good news indeed! Hey where is Maus92? I thought he would like to share in the good news about MADL's performance. Hey, I hear someone eating crow....could that be Mighty Maus :D?

Tested successfully at range "multiples" of spec can be said for other datalinks as well. The same could be said for DAS, capturing a known missile launch at extended range. And what exactly is that spec, for an interflight system? 10 miles? 20 miles? But props to NG/Harris/Raytheon for making it perform to spec

What seems to be ignored by the crow wishers is that the people who know how all the nets fit together realize MADLs shortcomings, and want another technology to enable wide area connectivity.

And yet MADL was not designed to be a WAN?

No, it was designed for high bandwidth comms between relatively closely spaced aircraft to share tactically significant data, images, stores and fuels states, etc, stealthily - all which makes it more of a "LAN," and less suitable for long range networking. The USAF has another network layer that they are developing to enable the "WAN," hopefully one that is more flexible and can be implemented by all blue force nodes.

It is what it is
It was designed to satisfy certain specs.
It exceeds it's specs by multiple times.
A good day for the Program.

In a sense both are right. MADL is intended to be a tactical data link, but that doesn't mean MADL doesn't have substantial range itself.

If you think about the fact that MADL is designed to reach outside of contested airspace from well within it that should give you some idea of at least the order of magnitude of the spec.

I wonder if this solution (or similar) will be applicable to the AWESOME F-35i?

Datalink solution is just around the corner By Arie Egozi 21 Mar 2013
"...Airforces that face many simultaneous missions have an operational demand for a lot of real-time information, of various types.

The solution is not simple, for the sender of the information and the receiver. But now it seems a solution is right around the corner.

An airborne datalink system will soon enable the Israeli air force to transmit and receive real-time video, data and audio simultaneously, using a small, lightweight radio....

...The source said the company had used advanced software and many off-the-shelf technologies to solve a "critical problem" of advanced airforces that use many types of manned aerial platforms in parallel to various unmanned air systems. Information has to be shared between them and "clients" on the ground in real time with a minimum of delay in voice transmissions."

A helmet update from Gen. Bogdan [from testimony earlier today before SASC]:

"We executed a short flight test program from November 2012 to March 2013 dedicated solely to exploring and understanding the helmet problems using developmental and operational test pilots flying a number of operationally representative missions. As a result of this testing, the program now understands and has mitigated the effects of ”green glow”, latency, jitter and alignment. Additional work still needs to be done to ensure that the program has a night vision camera that is effective for operations as our testing indicated that the current night vision camera is unsuitable for operational use. As risk reduction, the program continues to fund development of a night vision goggle-based alternative helmet solution. The goggle-based helmet development will continue until we see demonstrated improvement in all of the risk areas of the original helmet and until the government has secured a price agreement with the prime contractor showing significant cost reduction in the original helmet."
