The Space Development Agency will provide the unifying element in the Defense Department's future Joint All-Domain Command and Control concept, pulling together tactical networks developed by the services with a constellation of low-Earth orbit satellites.
With the JADC2 concept, the department envisions an overarching network capable of connecting sensors to shooters regardless of where they are located. That means U.S. Air Force sensors could feed data to U.S. Army shooters, or even National Reconnaissance Office sensors could send information to U.S. Air Force shooters.
“Each of the services have their own way to incorporate [tactical networks], and JADC2 is just a way to make sure they all have the same networking infrastructure to talk to one another, essentially,” SDA Director Derek Tournear said at the C4ISRNET Conference on May 6. “We plug directly into [JADC2] as the space layer to pull all of that communication together.”
Service efforts include programs like the Air Force's Advanced Battle Management System and the Army's TITAN ground system. What the Defense Department wants to ensure is that programs like these have a way to share data across the armed services.
“All of those are reliant on a way to be able to have a back end to go in space to be able to communicate across one another and across back to [the continental United States], etc. That's where the Space Development Agency's transport layer comes in,” Tournear said. “In fact, in the defense planning guidance, Secretary Esper put out the edict that basically said the transport layer will be the integrating aspect of JADC2 to be able to pull all of this tactical communication together in space.”
On May 1, the SDA released its solicitation for the first 10 satellites that will make up its transport layer — a space-based mesh network in low-Earth orbit. When fully developed, that transport layer will provide a global network that various sensors, shooters and tactical networks will be able to plug into for tactical communications.
A key part of that effort involves ensuring space-based sensors can feed into the services' battlefield networks in near-real time.
Once that transport layer is placed on orbit in 2022, the SDA wants to demonstrate space-based sensor data being downlinked to a ground station, then uplinked to the transport layer for dissemination to the tactical edge via TITAN and Link 16 tactical network. But ultimately, the SDA wants to cut out the ground station and move the data directly from the space-based sensor to the transport layer via optical cross links.
That's a stretch goal for those first 10 satellites, and the minimal viable product when the second tranche of 150 satellites is added in 2024, said Tournear.
Tournear declined to identify the SDA's mission partners on development of space-based sensors, which will need to use optical inter-satellite cross links to plug into the transport layer.

By: Mark Pomerleau The Army of the future will be leaner and that means junior officers will have more responsibility and more capability in their hands, a top Army general said Aug. 21. Lt. Gen. Theodore Martin, deputy commanding general of Training and Doctrine Command, said in future wars a platoon or company may be the unit that takes action. Martin, speaking at the TechNet Augusta conference, said that units have become smaller since World War I. Then, the U.S. military fought with huge field armies. World War II was fought with armies and corps, the Korean and Vietnam Wars were fought primarily with divisions, and the modern counterinsurgency wars have been fought with brigades, Martin said. With a potentially smaller, and leaner, structure, the junior officers that will command these units will have have capability within their power. “The type of assets that now reside at the brigade level, my grandfather ... if he were alive today [he] would be totally flabbergasted by what a colonel can bring to bear on the battlefield under his or her own authorities,” Martin said. Brigades today are led by colonels. In the future, Martin envision a lieutenant who will have grown up in a multidomain world with an education in the Army that is much different than that of today, and which prepared him or her for the future fight. Army leaders will expect that a platoon will take advantage of electronic warfare, cyber and information operations. This could mean the platoon will throw an electronic warfare grenade that will blind enemy mission command systems, jam radios and block similar attacks to keep friendly radios online. Then, as the platoon gets closer to its objective, perhaps they will send an email to the enemy commander saying something like their wife is cheating on them or their bank account has been emptied, as a way to create an additional distraction, Martin said. Martin acknowledged this vignette seems a little far-fetched, but in the multidomain battlefield “that's what we're going to be facing and it's a race to capability,” he said. https://www.c4isrnet.com/show-reporter/technet-augusta/2018/08/22/heres-how-one-army-leader-sees-the-future-of-war/

Airbus has revealed that it is exploring the introduction of military derivatives of the A320neo family. Speaking at the Singapore air show, Fernando Alonso, head of military aircraft at Airbus Defence & Space, said that the new platform could undertake missions such as VIP transport, intelligence, surveillance and reconnaissance and maritime patrol. "We have the knowledge of converting the A330 into the A330 MRTT [multirole tanker transport], and have a more efficient process." Alonso says that the efficiency of new-generation engines will enable a more capable military derivative. Any future conversion will require between "six to eight months" to complete, he says. Airbus is in talks with a number of operators, including the armed forces of Asia-Pacific nations such as Indonesia, Malaysia, New Zealand, the Philippines, alongside European stalwarts France, Germany and the Netherlands. The airframer is also working to add new capabilities to its existing military platforms: the A400M, A330 MRTT and C295. It will allow A400M operators to drop up to 60 paratroopers from both sides of the aircraft simultaneously, while the A330 MRTT is expected to be ready to conduct automatic air-to-air refuelling "in less than three years". Airbus is also exploring the possibility of allowing the remodelled widebody to take on ISR missions. Airbus is still proceeding with an "armed version" of the C295 medium transport, with the derivative in the engineering, development and testing phase. Flight tests will begin in late 2018. "There are big opportunities for us in Asia-Pacific: big fleets are here, budgets are here. We are able to fulfill needs in a more agile way," says Alonso. https://www.flightglobal.com/news/articles/singapore-airbus-explores-a320neo-military-derivati-445670/
