SpaceX, L3 to provide hypersonic tracking satellites for Space Development Agency

WASHINGTON — SpaceX and and L3 Harris will contribute satellites to track hypersonic weapons to the Space Development Agency's planned mega-constellation, with the nascent agency announcing Oct. 5 it has selected the two companies to build its first wide field of view satellites.

Under the contracts, each company will design and develop four satellites equipped with wide field of view (WFOV) overhead persistent infrared (OPIR) sensors. Operating in low Earth orbit, the sensors will make up the inaugural tranche of the SDA's tracking layer — the Pentagon's new effort to track hypersonic weapons from space.

“This SDA tracking layer is going to consist of a proliferated, heterogeneous constellation of WFOV space vehicles that provide persistent global coverage and custody capability. That's going to combine with activities in the Missile Defense Agency as they build toward their Hypersonic and Ballistic Tracking Space Sensor (HBTSS) medium field of view (MFOV) space vehicles,” Acting Deputy Undersecretary for Research and Engineering Mark Lewis told C4ISRNET.

Per the announcement, SpaceX will receive $149 million, while L3 Harris will receive $193 million. According to SDA Director Derek Tournear, the awards were the result of a full and open competition, with the selection based purely on technical merit.

SpaceX has made waves with its Starlink constellation — a series of satellites built to provide commercial broadband from low Earth orbit — and the Department of Defense has tested using Starlink to connect various weapon systems. However, the company does not have a history building OPIR sensors.

According to Tournear, the company will work with partners to develop the sensor, which it will then place on a bus it is providing. SpaceX already has a production line in place to build a bus based on its Starlink technologies, added Tournear.

“SpaceX had a very credible story along that line — a very compelling proposal. It was outstanding,” he said. “They are one of the ones that have been at the forefront of this commercialization and commodification route.”

L3 Harris will develop an OPIR solution based on decades of experience with small satellites, small telescopes and OPIR technologies.

“They had an extremely capable solution. They have a lot of experience flying affordable, rapid, small satellite buses for the department,” noted Tournear. “They had the plant and the line in place in order to produce these to hit our schedule.”

Tracking hypersonic weapons

The contracts are the latest development as the SDA fleshes out its National Defense Space Architecture (NDSA), a new constellation to be comprised of hundreds of satellites primarily operating in low Earth orbit. These satellites are expected to make up tranche 0 of the SDA's tracking layer, which will provide global coverage for tracking hypersonic threats.

The glue that holds the NDSA together will be the transport layer, a space-based mesh network made up of satellites connected by optical intersatellite links. Like most planned SDA satellites, WFOV satellites will plug directly into that network.

“The idea is it connects to the National Defense Space Architecture — the NDSA transport layer — via optical intersatellite links,” said Lewis. “And that will enable low latency dissemination for missile warning indications. It will provide track directly to the joint war fighters.”

SDA issued two contracts in August for its first 20 transport layer satellites. York Space Systems was awarded $94 million to build its 10 satellites, while Lockheed Martin was awarded $188 million for its 10 systems.

That transport layer capability is essential to the tracking layer's mission.

Because they are so much closer to the Earth's surface than the U.S. Space Force's missile tracking satellites in geosynchronous orbit, the WFOV sensors will naturally have a much more limited field of vision. In order to track globe traversing hypersonic missiles, the WFOV satellites will have to work together.

Once the first satellite picks up a threat, it will begin tracking it until it disappears over the horizon. During that time, it is expected to transmit its tracking data to other WFOV satellites over the transport layer. So as the first satellite loses sight of the threat over the horizon, the next WFOV is ready to pick it up, and so on and so forth.

From there, the WFOV satellites will pass the tracking data — either directly or via the transport layer — on to the medium field of view satellites being developed by the Missile Defense Agency as their HBTSS.

“SDA is developing the low cost proliferated WFOV space vehicles that provide the missile warning and the tracking information for national defense authorities, as well as tracking and cueing data for missile defense elements,” explained Lewis. “Meanwhile, the Missile Defense Agency is developing the high resolution HBTSS MFOV space vehicles — those can receive cues from other sources including the WFOV system — and they'll provide low latency fire control quality tracking data.”

“The MFOV HBTSS satellites will then be able to hone in and actually be able to calculate the fire control solution for that missile, send those data to the transport satellites with a laser [communication] system ... and then the transport system will disseminate that to the weapons platform as well as back to" the continental United States, where MDA can broadcast that information, added Tournear.

MDA issued $20 million contracts to Northrop Grumman, Leidos, Harris Corporation and Raytheon to develop HBTSS prototypes in Oct. 2019. Tournear noted that proposals for HBTSS “are being written as we speak.”

Together, HBTSS and the SDA's tracking layer are meant to provide the data needed to take out hypersonic threats — which Congress is increasingly concerned by.

“It's part of an integrated DoD OPIR strategy. So the wide field of view sensors and the medium field of view sensors are really integral to this whole NDSA system and legacy strategic missile warning capability,” said Lewis, praising MDA and SDA for working together to build a heterogeneous solution.

Spiral development

Of course, this initial tranche won't provide global coverage up front. As part of its spiral development approach, SDA plans to continuously add satellites to its mega-constellation in two-year tranches, with each tranche including more advanced technology. The tracking layer is not expected to reach global coverage until 2026, said Tournear.

But as the constellation is built out, the more limited initial capabilities will be used to help integrate the space-based assets with war fighters.

“We call tranche 0 our war fighter immersion tranche,” said Tournear. “What that means is, its goal is to provide the data in a format that the war fighters are used to seeing on tactical timelines that they can be expected to see once we actually become operational. The whole purpose of tranche 0 is to allow the war fighters to start to train and develop tactics, techniques and procedures so that they can create operational plans for a battle where they would actually incorporate these data.”

With tranche 1 in 2024, the tracking and transport layers will essentially reach initial operating capability, said Tournear. That will include persistent regional coverage.

According to Tournear, the tranche 0 satellites are set to launch in September 2022.

Tournear told C4ISRNET his agency is planning to issue a separate solicitation for launch services later this week. That solicitation will cover all of the tranche 0 satellites, including the 20 transport layer satellites the agency ordered in August, the eight WFOV satellites and the HBTSS satellites.

    Finland’s Air Force chief tackles recruiting challenges and its quest for a future fighter

    By: Valerie Insinna TIKKAKOSKI, Finland — The Finnish Air Force is changing. In a matter of years, it will decide on its future fighter — a €7-€10 billion (U.S. $7.8-$11.2 billion) program that could tie Finland more closely to the country that wins the competition. It's revamping its command-and-control infrastructure. And like other international air forces, it's putting increased pressure on itself to boost readiness. Maj. Gen. Pasi Jokinen, who became the commander of Finland's Air Force in April, oversees the transformation. The job has its perks: During U.S. Air Force Chief of Staff Gen. Dave Goldfein's trip to Finland in July — his first visit to the nation — the two officers took a break from meetings and sat backseat in two Finnish F/A-18 Hornets for a training mission. Goldfein later said the flight signified the growing trust between the two air forces. Jokinen spoke on July 21 with Defense News, which traveled to Finland with Goldfein, about the service's readiness challenges and its modernization priorities. Tell me about your conversation here today with Gen. Goldfein. Well, we talked about a lot of interesting topics. We talked about the operation environment and the Finnish Air Force and what we do here, and the cooperation with the U.S. and all that. He obviously was aware of a lot of things, but we went into very good detail about everything like that. We know what's happening here, we are strongly here, we are committed here and everything is running smoothly. You said you talked about the operational environment for Finland right now. Can you characterize that, and is it changing? Well, I think we have been using that word “new normal” after Crimea and after 2014, so activity in the Baltic region and in this region is in a little bit elevated level — let's put it that way. And of course our eastern neighbor is actively doing things in Syria and eastern Ukraine. It has had some effects. It seems that they have this big exercise cycle, [in] running the Zapad [exercise] and how they rotate the different regions. In 2017 we saw again this western Russia exercise, and it was noted. It was at peak activity level. Activity-wise, 2017 was the highlight, and now we are calmed down a little bit, but still we are above the level before 2014. Is it fair to say that the number of intercepts peaked in 2017? Yeah, well, when their activity is high, our activity is high. And of course the Gulf of Finland, which is the international airspace nearby our border, that's one of the areas of interest. You used the word “intercepts,” though; that activity is there. I mean, of course then they are operating also in the other, the northeast and eastern border, but that's a solid border. I mean, obviously they are on their side and we are on our side. Then the international airspace where we meet, OK. The Gulf of Finland is mainly transit for mainland Russia to Kaliningrad and back, and in the southern Baltic Sea, or the Baltic sea down more south, there's more room to maneuver, do stuff like that. Here is the very narrow — long but narrow — corridor that normally there is no operational type of maneuvers, neither side, but it's a transit. But we like to know who is going where and all that. Then obviously one the things are that they do not always use transponders or flight plans. There are no flight plans, so we need to find out who is there. That has improved a bit over the years. The equipment is newer and they have the western transponders and they use them, so it's a little bit better situation that we had a few years back, but it's not 100 percent covered with the flight plans or transponders. As you look across the entire Air Force, what's your No. 1 concern? Is it budget? Is it what you're seeing threat-wise from potential adversaries? Well, I'm not concerned about the adversary. Things are relatively stable. We have good relations in all the directions, all directions there. Defense forces in general has been resourced relatively well. The readiness, of course, requires some money. And of course the Army has had a bigger transition the last few years out of the services, from a training organization into a readiness organization. There's of course a need for more money, for operating money also. And the government has been giving quite good money in the last few years. Now the future is not that bright. I mean, there's some dark clouds there. I'm concerned. Of course, the main procurement program, like the HX [fighter replacement program], seems to be well on track, and I'm very happy about that, and that is their main priority, of course, to keep that in schedule and in budget for the procurement side of the house. People have been — I don't know if “stressed” is the right word — but they have been under pressure for the readiness, and we've also gotten more vacant jobs. We are recruiting people, people on the field and into the practical work— so the aircraft maintenance, the surveillance tasks. It's very important that the recruitment works. Aside from HX, are there other modernization efforts that you're trying to keep on track? Well, we are, before the HX selection, before the HX comes in. Right now we are working on our C4I system. But we have had quite a lot of new pieces there and they are IOC [initial operational capability], becoming FOC [full operational capability]. Then whatever solution or whatever HX candidate is chosen, there is a requirement to be able to process and handle all that [information]. So we are working that before so when selection is done and it's actually coming in, the infrastructure is prepared for that. Obviously we need to then fine-tune it, depending on the selection, at the end of the day, but right now we are working on the basic infrastructure. What has Finland already fielded? What is coming up that is still in the planning stages or in the competitive stages? For the C4 side of house? Well, OK, we've got our sensors, relative new sensors for the surveillance sensors. And our networks and the infrastructure and the servers, kind of like the infrastructure there, both the networks and for the servers. They are relatively new. So it's there, and we are getting that into use as we speak or in the near future. Then it's all about the processes and methods and how to handle the data and how to use the data. So that's something that people in organizations need to learn. Not the hardware, but the people need to learn, so that's something that we are working on. Then, when we get the HX here and we know what it is, then we do the necessary adjustments. And it's obviously platform-specific and [dependent on] the requirements there. In all cases, we need to be able to be better in joint warfare inside Finland with data services and of course maintain the international interoperability portion, whether it's about tactical data links or whether it's other things. Did you discuss interoperability with the U.S. Air Force with Gen. Goldfein? Well, yeah, sure. Technology is one thing. You are interoperable and you can use the data and all that. But the processes [of] how you do it is one thing, but then there's this policy side of the house, that if you don't have the policy or to actually be there — interoperable all the time — then you just need to be prepared for that. We are an independent nation. We are not a NATO member, and we are not doing common planning. We are operating as neighbors here. Our AOR [area of responsibility] and the EUCOM [U.S. European Command] AOR and NATO AOR, they are all overlapping or next to each other. Coordination and deconfliction [are] some things that we need to be ready to do. The policy is important and the SOPs [standard operating procedures] and all that. The U.S. is interested in rapidly generating air power in times of crisis. How can the U.S. better defend its bases or set up new expeditionary air bases if needed? From what I understand, that's something that Finland has the capability to do. Did that come up in conversation, and do you think that there are things that the U.S. can learn from Finland in that area? In Finland, we have our main base. But yes, we can deploy and we can swarm, distribute our assets, and then have them under the command and control, and make centralized effects out of those distributed things. So yeah, that was talked about. Of course, it requires the ability to move and begin to move [your resources from the base]. It requires a good situational awareness and plans [for] how to do it, and then the timely execution of that. We've talked about the general concept, and yes, it was mentioned by Gen. Goldfein that they are looking for a more expeditionary mindset, that huge massive bases that you can generate the air power may not be the thing that you want to stick. Finland is not that small [of an] area. There are smaller nations than us, but still in the global or the U.S. scale, it's still a small area. The thing is to look for the agility and mobility and know what's happening and do the right things from there, either move or disperse. Is that a capability in which Finland continues to invest? Yeah, it's part of the HX program. So now the question is how much. It's good for that fight that you distribute, but the main operation is get out there and do the job, then come back and you can go out again. That is the important thing — that you get the effect in the air, what you're doing from the air or in the air. Then it's nice for the survivability part and all that to be distributed. That's what we are still looking [at]. But then, to what extent? That is to be determined. We will find it out when the HX goes forward. On HX, I understand Finland is looking for some industrial incentives. Has it become clear yet what each company might be willing to offer? We are in the middle of the process. I don't know whether the offers are final. We have the ideas that we are discussing. There is a requirement that we need to be able to do certain stuff in Finland, with the Finnish resources and [people with] Finnish passports. That is a requirement [that] is still there. How do you think Finland will have to balance the cost of this project with the capability it wants? That equation needs to be solved, but we have two years of time to solve it. We have the money — €7 billion to €10 billion. And we need to maximize the capability on that money. Are you making additional investments in intelligence, surveillance and reconnaissance capabilities? There is a desire to have the proper amount of ISR. Obviously the HX is going bring something into it, and we also have a recent area there that we are investigating. Probably when there's better visibility, when we are actually selecting and getting through HX, then we [will] know where the gaps are, and then we are going to fill them in [with] other programs. https://www.defensenews.com/2019/08/09/finlands-air-force-chief-tackles-recruiting-challenges-and-its-quest-for-a-future-fighter/

    USAF issues RFI for directed energy C-UAS technologies

    by Pat Host The US Air Force (USAF) is requesting information from industry about directed energy (DE) capabilities for counter-unmanned aerial system (C-UAS) technologies. The Air Force Life Cycle Management Center, Architecture and Integration Directorate (AFLCMC/XA) seeks to better characterise the technological, manufacturing, and performance capabilities of the industrial base to develop and produce upgrades to DE prototypes and related C-UAS subsystems. The directorate will use this information to inform its trade space analysis of solutions for engagement and mission level modelling and simulation (M&S), as well as programme cost estimates for potential future technical maturation of DE C-UAS systems. The USAF wants to research the industrial base for C-UAS capabilities related to fixed-site Air Base Air Defense (ABAD) against potential Group 1 and 2 UAS threats, which weigh 25 kg or less. These threats may have characteristics such as small size; low radar cross sections; low infrared (IR) or radio frequency (RF) signatures, or no RF signatures at all; the ability to hover; and low-altitude flight capabilities, which may render them difficult to detect and defeat. Additionally, these UASs are typically either controlled remotely from a ground control station (GCS) or can fly pre-programmed routes. Recent and pending procurements of DE C-UAS weapons require even further development and improvement, including connected and related, but not limited to, subsystems such as command-and-control (C2) suites, radar, and electronic warfare (EW). https://www.janes.com/defence-news/news-detail/usaf-issues-rfi-for-directed-energy-c-uas-technologies
