The Air Force is developing software and ground equipment to boost the protection of the Wideband Global satcom system. First in line for the upgrade are naval carrier strike groups. The Navy will get the new technology in 2022, about 18 months sooner than previously planned.
WASHINGTON — The Air Force is cyber hardening military satellite communications equipment amid worries that foreign hackers could infiltrate U.S. networks.
“Adversaries are getting better and more able to penetrate our unclassified or barely protected systems,” said Col. Tim Mckenzie chief of the advanced development division for military satellite communications at the Air Force Space and Missile Systems Center.
The bulk of military satcom services are provided by the Air Force Wideband Global Satcom, or WGS, satellites and by commercial operators. All these systems require additional protection from cyber attacks, Mckenzie told SpaceNews in a recent interview.
“Commercial satcom as well as our own purpose-built Wideband satellites were never designed to provide protection against some of the things we expect our adversaries to do in the near future,” he said.
In response, the Air Force is developing software and satcom ground equipment to boost the protection of WGS networks in the near term, and commercial systems at a later time. First in line for these upgrades are the Navy's aircraft carrier strike groups in the Pacific, Mckenzie said. The Air Force will have this technology available for carrier strike groups in 2022, about 18 months sooner than previously planned.
The central piece of the cyber security upgrade is anti-jam communications software — called the Protected Tactical Waveform (PTW). A ground system, the Protected Tactical Enterprise Service (PTES) will manage the transmission of the waveform over WGS satellites and terminals.
Boeing, which manufactures the WGS satellites, was awarded a seven-year, $383 million contract in November to develop the PTES.
“We are doing agile software development to enable early use of the PTW capability,” said Mckenzie.
The anti-jam software and ground system only will work initially with WGS networks, said Mckenzie. If a commercial provider opted to use the PTW waveform, the ground system could be updated to interoperate with that vendor's network.
Military satcom users will need to upgrade their satellite terminals with new modems to operate the PTW waveform. The Air Force two years ago awarded three contracts — $39 million to Raytheon, $38 million to L3 and $33 million to Viasat — to develop prototype modems. The Army, Navy and Air Force will run separate competitions to decide which modems they will acquire for their specific terminals. For carrier strike groups, the Navy will have to buy PTW-capable modems to upgrade its satellite terminals aboard ships.
In the long term, the plan is to add a new space component — either newly designed spacecraft or military communications payloads hosted on commercial buses. “Our goal is to have some protected tactical satcom prototype payloads on orbit in the fiscal year 2025 time frame,” said Mckenzie.
Whatever new hardware makes up the space segment, it will be compatible with the PTES ground equipment, he said. Mckenzie noted that the Air Force has been criticized for deploying satellites before the ground equipment is available. The PTW and PTES efforts reverse that trend. “We have learned lessons from being out of sync with terminals on the ground,” Mckenzie said. “We've been working for the last several years to develop modem upgrades that can be put into our existing terminals so we have terminals that can use PTW.”
To get fresh thinking on how to develop a secure satcom system, the Air Force Space Enterprise Consortium is funding four design and prototyping projects. These are four areas “where we're trying o reduce risk,” said McKenzie. The consortium was stood up in 2017 and given authorities to kick start projects with far less red tape than traditional Pentagon contracting. Mckenzie said the Air Force is interested in new ideas for constellation architectures, payload hosting concepts, advanced space processing and antenna designs.
McKenzie expects contracts for the development of protected tactical satcom payloads will be awarded in fiscal year 2020, with a goal to start launching new systems into orbit by 2025.
Boeing, Northrop Grumman, Raytheon and X-Band LLC have entered into cost-sharing agreements with the Air Force — contracts known as Other Transactions Authority — to map out constellation sizes, layouts, design lives, and concepts such as hosting of military payloads as a commercial service.
Boeing, Lockheed Martin, Northrop Grumman and SSL have signed OTA agreements to develop phased arrays and array fed reflectors antennas.
BAE Systems, L3 and SEAKR Engineering received OTA deals to investigate requirements for secure satcom applications such as geo-location, waveform processing, and anti-jam. Boeing and Southwest Research Institute are studying hosting concepts, such as identifying interface commonalities between commercial and military bus providers and recommends ways to simplify the integration.
Tom Becht, military satcom director at the Air Force Space and Missile Systems Center, said the protected tactical satcom effort has been underway for more than eight years and now is being accelerated as the Air Force seeks to respond to military commanders' needs in a more timely fashion. “The demand for protected satcom has significantly increased,” Becht said in an interview.
After the PTW, PTES and the new space segment are deployed, the next step will be to modernize the military's nuclear-hardened strategic satcom system, the Advanced Extremely High Frequency constellation. Most of the users of the AEHF system are tactical operators and the Pentagon eventually wants to have a dedicated strategic satcom constellation for nuclear command and control. “Tactical users will transition to the Protected Tactical Satcom system,” said Becht.
That transition could take decades, he said. “The aggregated [tactical and strategic] AEHF will be around until the mid 2030s or a bit longer.”

By: Eric Lofgren Congress' unprecedented fiscal response to COVID-19 has many in the defense community wondering whether belt tightening will hit the Pentagon. On May 19, the Congressional Progressive Caucus wrote a letter arguing for substantial defense budget cuts to support additional spending on the pandemic. Nonprofit progressive supporters have been asking to cut a much larger $350 billion each year from the Pentagon in their “Moral Budget” proposal. What the progressives perhaps do not fully appreciate is the “stickiness” of defense budgets. In economics, stickiness refers to rigidity in the movement of wages and prices despite broader economic shifts pushing for new equilibrium. The phenomenon is apparent in defense budgets as well. Most expectations are that the fiscal 2021 budget will remain over $700 billion. Consider an analogy: the 2008 financial crisis. Lehman Brothers collapsed just a couple weeks before fiscal year 2009 started, leaving that $666 billion defense budget largely beyond recall. The following years' budgets were $691 billion, $687 billion, $646 billion and then finally in FY13 a more precipitous 10 percent fall to $578 billion. It took four years for the Pentagon to really feel the squeeze of the financial downturn. The uninitiated may believe COVID-19 happened with enough of lead time to affect the FY21 budget. Congress received the president's budget in February 2020 and has until the start of October to make targeted cuts without encountering another continuing resolution. The defense budget, however, represents the culmination of a multiyear process balancing thousands of stakeholder interests. It reflects a vast amount of information processed at every level of the military enterprise. The Pentagon's work on the FY21 budget request started nearly two years ahead of time and includes a register of funding estimates out to FY25. Moreover, defense programs are devised and approved based on life-cycle cost and schedule estimates. Cuts to a thorough plan may flip the analysis of alternatives on its head, recommending pivots to new systems or architectures and upsetting contract performance. Not only are current budgets shaped by many years of planning, but they get detailed to an almost microscopic level. For example, the Army's FY21 research, development, test and evaluation request totaled $12.8 billion, less than 2 percent of the overall Pentagon request. Yet the appropriation identifies 267 program elements decomposing into a staggering 2,883 budget program activity codes averaging less than $10 million each. Congressional staff is too small to understand the implications of many cost, schedule and technical trade-offs. To gather information on impacts, the Pentagon is thrown into a frenzy of fire drills. More draconian measures, like the FY13 sequestration, leading to indiscriminate, across-the-board cuts can sidestep hard questions but comes at a significant cost to efficiency. Targeted cuts at a strategic level, such as to the nuclear recapitalization programs and other big-ticket items, can expect stiff resistance. First, there is real concern about great power competition and the damage that may be wrought by acting on short-term impulses. Second, targeted programs and their contractors will immediately report the estimated number of job losses by district. Before measures can get passed, a coalition of congressional members negatively impacted may oppose the cuts. Resistance is intensified considering the proximity to Election Day. Budget stickiness is built into the political process. The FY22 budget is perhaps the first Pentagon budget that can start inching downward. More than likely, severe cuts aren't in the offing until FY23 or FY24 at the very earliest. That gives time for policymakers to reflect on the scale of the rebalancing between defense and other priorities. In some important ways, congressional control of the Pentagon through many thousands of budget line items restricts its own flexibility. For example, continuing resolutions lock in program funding to the previous year's level until political disagreements can be resolved. The military cannot stick to its own plans, much less start new things. If budget lines were detailed at a higher level, such as by major organization or capability area, then the Pentagon could make more trade-offs while Congress debates. Similarly, if the Pentagon had more budget flexibility, then Congress could more easily cut top lines and allow Pentagon leaders to figure out how to maximize with the constraint during the year of execution. Congress could gain the option to defer the hard questions that can make cuts politically difficult. The Space Force recently released a proposal for consolidating budget line items into higher-level capability areas. It reflects the idea that portfolio-centric management is an efficient method of handling rapid changes in technologies, requirements or financial guidance resulting from economic shocks. Until such reforms are pursued, expect defense budgets to remain sticky. Eric Lofgren is a research fellow at the Center for Government Contracting at George Mason University.
