Para trabajar en red se necesita poder transmitir mucha información con poca posibilidad de ser interferida y detectada. Hasta ahora la red se solía hacer con MIDS/Link 16, pero ahora se quieren otras soluciones (se barajan distintas posibilidades, supongo que habrá que esperar a ver qué se decide en la OTAN), por ejemplo las que han empezado a implementar los cazas furtivos useños: (de http://aviationweek.com/defense/5th-4th ... iscal-2015 )
Además de lo anterior está el MIDS-JTRS: (de http://www.naval-technology.com/news/ne ... rs-4737177 )Though called "5th to 4th," a major long-term issue is how to allow for the F-22 and F-35 to communicate without using Link 16 alone, which would compromise their stealthy operations. Though both are manufactured by Lockheed Martin to meet Air Force needs, they were designed in different eras. F-22s can essentially only "talk" to other F-22s through a dedicated, low-probability-of-detection/low-probability-of-intercept system. The F-35, by contrast, uses the Multi-function Advanced Datalink (MADL) system, which employs a different waveform; the F-35 is slated for its Air Force operational debut as early as August 2016....
...Both the F-22 and F-35 can receive Link 16 signals, but doing so might compromise their location if operations require stealth. So one question being addressed by Air Force officials is how to provide connectivity that is LPI/LPD while fifth-generation fighters are in the most dangerous airspace, where they were designed to operate.
Genatempo says the service is open to taking incremental steps toward the ultimate goal of fielding a direct link between the F-22 and F-35. He says cost is a key concern. "The biggest part I am trying to keep a cost control on is the development piece," he says. Production numbers would ultimately be dictated by the available budget.
The service hopes to eventually network the stealthy fighters and fourth-generation combat forces with other Pentagon assets, such as intelligence, surveillance and reconnaissance aircraft and satellites, Genatempo says, although this is not a firm requirement.
Boeing, Northrop Grumman and Lockheed Martin are all expected to submit concepts for MAPS. Northrop Grumman has demonstrated a similar gateway capability through the Jetpack joint capability technology program. Jetpack is designed to translate F-22 and F-35 messages into Link 16 messages to distribute the data to fourth-generation fighters (or forces operating on Link 16).
Lockheed Martin, by contrast, has demonstrated the ability to use a new waveform developed by L-3 Communications called Chameleon for direct communications among F-22s and F-35s without the use of a gateway. Lockheed Martin demonstrated Chameleon during flight trials in December; officials say signal strength remained under the detection threshold for an anti-access environment and the waveform can be transmitted via L-band antennas already on both platforms and only used for operations now at test ranges.
Lockheed Martin has spent its own internal research and development funding to develop the system, dubbed Project Missouri. What is unique about Project Missouri is its ability to allow for data to go back and forth using the Chameleon waveform without revealing the location of the stealthy aircraft, a plus for operations in highly defended airspace.
Y seguro que me dejo bastantes cosas más... el futuro es el combate en red (y por tanto es fundamental definir los drones que principalmente la nutrirán... y también, claro, el protocolo de la red)... los cazas... bueno sí, supongo que alguno se necesitará.Data Link Solutions (DLS), a joint-venture between BAE Systems and Rockwell Collins, is set to test enhanced communications capabilities between fifth and fourth generation fighter jets.
Under a contract awarded by the Space and Naval Warfare Systems Command (SPAWAR), the company will demonstrate the multifunction advanced data link (MADL) on the multifunctional information distribution system (MIDS) joint tactical radio system (MIDS JTRS).
For the testing that is planned to be conducted in the third quarter of this year, the company will use a MADL data link on a MIDS JTRS transceiver, communicating with fifth-generation stealth fighter reference implementation.
