Next-Stage C4ISR Bandwidth: The AEHF Satellite Program

The USA’s new Advanced Extremely High Frequency (AEHF) satellites will support twice as many tactical networks as the current Milstar II satellites, while providing 10-12 times the bandwidth capacity and 6 times the data rate transfer speed. With the cancellation of the higher-capacity TSAT program, AEHF will form the secure, hardened backbone of the Pentagon’s future Military Satellite Communications (MILSATCOM) architecture, with a mission set that includes nuclear command and control. Its companion Family of Advanced Beyond-line-of-sight Terminals (FAB-T) program will give the US military more modern, higher-bandwidth receiving capabilities, and add more flexibility on the front lines. The program has international components, and partners currently include Britain, Canada, and the Netherlands.

This article offers a look at the AEHF system’s rationale and capabilities, while offering insight into some of the program’s problems, and an updated timeline covering over $5 billion worth of contracts since the program’s inception.

Missile Envy: Modernizing the US ICBM Force

For 50 years, land-based Intercontinental Ballistic Missiles (ICBMs) have been part of the US primary strategic deterrence capability, the nuclear-armed triad that also includes submarine-launched ballistic missiles and long range heavy bombers.

Although the main target for the US deterrent – the Soviet Union – imploded in 1991, other threats – such as nuclear-armed rogue states and non-state actors – have emerged. To address these new threats, the US Air Force undertook a major ICBM modernization program.

To carry out this program, the USAF awarded a 15-year ICBM Prime Integration Contract (F42610-98-C-0001) in 1997 to a team led by Northrop Grumman. Since then, the team, which includes Lockheed Martin, Boeing, and ATK, has been carrying out a major modernization of the ICBM system to ensure its readiness.

Future GPS: The USA’s GPS-III Programs

GPS-III satellites, in conjunction with their companion OCX ground control, system are the Global Positioning System (GPS) future. They offer big advantages over existing GPS-II satellites and GCS, but most of all, they have to work. Disruption or decay of the critical capabilities provided by the USA’s Navstar satellites would cripple both the US military, and many aspects of the global economy.

The time-based GPS service is the most-used application of Einstein’s Theories of Relativity. GPS has become part of civilian life in ways that go go far beyond those handy driving maps, including crop planting, timing services for stock trades, and a key role in credit card processing. At the same time, military class (M-code) GPS guidance can now be found in everything from cruise missiles and various precision-guided bombs, to battlefield rockets and even artillery shells. Combat search and rescue radios rely on this line of communication, and so does a broadening array of individual soldier equipment.

This DII FOCUS article looks at the existing constellation, GPS-III improvements, the program’s structure, its progress through contracts and key milestones, and extensive PTN (Positioning, Timing & Navigation)/ GNSS (Global Navigation Satellite System) research links.

The Rockets’ Red Ink: from EELV to a Competitive Space Launch Future

The EELV program was designed to reduce the cost of government space launches through greater contractor competition, and modifiable rocket families whose system requirements emphasized simplicity, commonality, standardization, new applications of existing technology, streamlined manufacturing capabilities, and more efficient launch-site processing. Result: the Delta IV (Boeing) and Atlas V (Lockheed Martin) heavy rockets.

Paradoxically, that very program may have forced the October 2006 merger of Boeing & Lockheed Martin’s rocket divisions. Crosslink Magazine’s Winter 2004 article “EELV: The Next Stage of Space Launch” offers an excellent briefing that covers EELV’s program innovations and results, while a detailed National Taxpayer’s Union letter to Congress takes a much less positive view. This DID Spotlight article looks at the Delta IV and Atlas V rockets, emerging challengers like SpaceX and the new competition framework, and the US government contracts placed since the merger that formed the United Launch Alliance.

The International Wideband Global SATCOM (WGS) Program

The US military needs a bigger data firehose. In an era of streaming data from proliferating UAVs and other persistent surveillance platforms, and the need for control of those systems anywhere in the world, bandwidth is almost as important as fuel. Commercial satellite communications (SATCOM) can fill some of the gaps, but it’s expensive, and may not be available when needed. The Wideband Gapfiller SATCOM (now Wideband Global SATCOM) program began as a way to ease these problems in the near term, but went on to become one of the twin pillars of US military communications, alongside the hardened AEHF constellation. Both satellite types expanded their roles after the super-high bandwidth T-SAT program was canceled. Instead, the USA is adding WGS and AEHF satellites in space, even as it makes both programs multi-national efforts here on earth.

WGS is a set of 13-kilowatt spacecraft based on Boeing’s model 702 commercial satellite. These satellites will handle a significant portion of the USA’s warfighting bandwidth requirements, supporting tactical C4ISR(command, control, communications, and computers; intelligence, surveillance, and reconnaissance); battle management; and combat support needs. Upon its 2007 launch into geosynchronous orbit, WGS Flight 1 became the U.S. Department of Defense’s highest capacity communication satellite. WGS F4, launched in January 2012, offers further improvements, as do satellites from WGS F8. The constellation is set to grow to 10, including international participation.

This is DID’s FOCUS Article covering the WGS program’s specifications, budgets, travails, international partnerships, and contracts, with links to additional research materials.

Keep A Spare Handy: US Navy Orders its 5th MUOS COMSAT

Lockheed Martin recently announced a $339.6-million contract option from the U.S. Navy for the 5th and final planned satellite in the Mobile User Objective System (MUOS) constellation. Under the current plan, the 5th satellite would serve as an on-orbit spare, and the capstone of a $3.26 billion acquisition program – though schedule slips have delayed the launch of even the 1st MUOS satellite from 2009 to December 2011.

Budget Busters: The USA’s SBIRS-High Missile Warning Satellites

The Space Based Infrared System (SBIRS)-High satellite program is a key component of the USA’s future missile alert system, designed to give maximum warning and monitoring of ballistic missile launches anywhere in the world. The new satellites will replace the existing Defense Support Program (DSP) fleet. Their infrared sensors have 3x the sensitivity of DSP and 2x the revisit rate, while providing better persistent coverage.

Unfortunately, the program has been beset by massive cost overruns on the order of 400%, technical challenges that continue to present problems, and uncertainties about performance. Despite these problems, the U.S. Air Force is proceeding with the program, and has terminated potential alternatives and supplements. However, as part of a January 2015 effort to institute cost reforms, the Air Force will weaken requirements for the program, and at least three other major procurement programs.

DSP Satellites: Supporting America’s Early-Warning System

Defense Support Program (DSP) satellites have been monitoring the skies as America’s early-warning system for ballistic missile launches since their first launch in 1970. The current Satellite Early Warning System (SEWS) consists of 5 DSP satellites; 3 provide frontline operational service, with 2 available as backups should problems emerge with the primary satellites.

The program’s lifetime has seen the launch of 23 DSP satellites, and improvements to DSP via 5 upgrade sets have allowed those satellites to exceed their design lifespan. The USAF’s fact sheet lists the satellites’ unit cost at $400 million, though they do not mention what fiscal year baseline that figure is linked to. While the DSP satellites successfully detected Iraqi SCUD launches during Operation Desert Storm, testimony before Congress has noted that there are some classes of missiles the DSP constellation has trouble with. The USAF’s way over-budget SBIRS program was created to address that, but the DSP constellation will be up for a long time. This entry will be updated to cover new developments, contracts, and more.

Space Based Space Surveillance: Follow On Needed

In January 2001, a commission headed by then US Defense Secretary-designate Donald Rumsfeld warned about a possible “space Pearl Harbor” in which a potential enemy would launch a surprise attack against US-based military space assets, disabling them. These assets include communications satellites and the GPS system, which is crucial for precision attack missiles and a host of military systems.

“The US is more dependent on space than any other nation. Yet the threat to the US and its allies in and from space does not command the attention it merits,” the commission warned.

One of the systems that grew out of the commission’s report was the Space Based Space Surveillance (SBSS) project, which is developing a constellation of satellites to provide the US military with space situational awareness using visible sensors. After a slow start, SBSS Block 10 reached a significant milestone in August 2012 with its Initial Operational Capability, followed by full operational capability less than a year later. But lack of funding casts as shadow on whether this capability will be maintained beyond 2017. By 2014/15 the Air Force worked on a stopgap project as well as an effort to obtain proper funding for follow on satellites to be launched at the start of next decade.

Trident D-5 SLBM Maintenance: Rocket Motors, Guidance

Trident II D-5

Carried on SSBN-726 Ohio Class submarines, The Trident II D-5 is the US Navy’s submarine launched nuclear missile, with exceptional range for a sea-launched weapon and accuracy figures that rival or even exceed land-based ICBMs. These missiles are arguably the most important and effective component of the US nuclear deterrent, and they constitute Britain’s entire nuclear deterrent as well. They were first deployed in 1990, and are planned for continuous deployment to 2042.

The US Navy’s Strategic Systems Programs in Washington, DC and Lockheed Martin recently issued over $100 million in contracts related to the Trident II D-5 SLBMs, in order to maintain their propulsion and guidance systems.
