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.

Don’t Touch Their Junk: USAF’s SSA Tracking Space Debris

Space Fence concept

Space is big. Objects in space are very dangerous to each other. Countries that intend to launch objects into space need to know what’s out there, in order to avoid disasters like the 2009 collision of 2 orbital satellites. All they need to do is track many thousands of man-made space objects, traveling at about 9 times the speed of a bullet, and residing in a search area that’s 220,000 times the volume of Earth’s oceans.

The US Air Force Materiel Command’s Electronic Systems Center at Hanscom Air Force Base in Massachusetts leads the USA’s Space Fence project. It’s intended to improve space situational awareness by tracking more and smaller objects, while replacing legacy systems in the Space Surveillance Network (SSN) as they retire. With a total anticipated value of around $6.1 billion over its lifetime, Space Fence will deliver a system of 2-3 geographically dispersed ground-based radars to provide timely assessment of space objects, events, and debris. International cooperation will supplement it, as part of overall Space Situational Awareness efforts. Failure is not an option. Or is it?

Skynet 5: UK MoD’s Innovative SATCOM Solution

Skynet 5 satellite model

When militaries around the world have wanted to expand their satellite communication (SATCOM) capacity, they traditionally have had 2 choices – either pay a satellite manufacturer billions of dollars to build a satellite constellation and then own and operate the constellation themselves or lease capacity on commercial satellites, with all the attendant concerns about availability and security.

The UK Ministry of Defence (MoD) came up with an innovative approach to expanding its SATCOM capacity called Skynet 5.

Through a GBP 3.6 billion UK MoD private finance initiative (PFI), EADS Astrium manufactures the Skynet 5 satellites and Paradigm owns, manages, and operates the Skynet constellation. The satellites are built to UK military specifications and the UK is committed to purchasing satellite capacity from Paradigm, an EADS Astrium subsidiary.

Space Based Space Surveillance: Follow On Needed

SBSS Constellation

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.

Hypersonic Rocket-Plane Program Inches Along, Stalls, To Restart

FALCON HTVs

The path toward a hypersonic space plane has been a slow one, filled with twists and turns one would expect given the technological leap involved. Speeds of Mach 8+ place tremendous heat and resistance stresses on a craft. Building a vehicle that is both light enough to achieve the speeds desired at reasonable cost, and robust enough to survive those speeds, is no easy task.

Despite the considerable engineering challenges ahead, the potential of a truly hypersonic aircraft for reconnaissance, global strike/ transport, and low-cost access to near-space and space is a compelling goal on both engineering and military grounds. The question, as always, will be balancing the need for funding to prove out new designs and concepts, with risk management that ensures limited exposure if it becomes clear that the challenge is still too great. In October 2008, the US Congress decided that FALCON/Blackswift had reached those limits. That decision led to the program’s cancellation, though some activities will continue.

Requests for Proposals Round Up, Early-September 2011

Federal Business Opportunities (FBO) has recently released the following Requests for Proposals (RFP), modifications and other notifications:

• The US Navy adds an additional clause and extends the closing date to 9th September for its RFP for a Firm Fixed Price (FFP) contract for the acquisition of engineering and technical support services for the Virginia Class (SSN 774) submarine and the Ohio Replacement Program (ORP).

Iridium’s NEXT Satellites: Global Reach, New Partnerships

Iridium constellation

Most of us remember Iridium as the Motorola-backed, multi-billion dollar commercial satellite phone flop. The expensive, bulky phones, the $2 per minute airtime charge, and the inability to use the phone inside buildings doomed the project, which came online when the cell phone market was taking off. Despite all these problems, the US military found the low-bandwidth satellites and phones very useful in remote areas. So the Pentagon backed an effort for the constellation to be acquired by investors at a fraction of the original $5 billion development cost, and became the revived satellite company’s largest customer.

Iridium Communications Inc. has been steadily picking up customers beyond the Pentagon. They now have almost 360,000 subscribers, and in 2007, they began planing a second-generation satellite constellation called Iridium NEXT. With launches expected to begin in 2015, Iridium NEXT will offer higher data speeds, flexible bandwidth allocation, and IP-based routing. In the meantime, militaries have found innovative ways to use Iridium’s services, making Iridium NEXT a privately-held but significant space resource for future military operations.

Up to $65M to Maintain Key COBRA DANE Radar

COBRA DANE

March 29/11: Raytheon Technical Services Co. in Dulles, VA receives an $11.9 million firm-fixed-price radar operations and maintenance contract modification. The firm will ensure the availability of the COBRA DANE radar facility, to a performance standard that can “collect 100% of the tasked data collection opportunities that pass through its field of view.” Work will be performed in Indianapolis, IN. The AFISRA/A7KRB at Patrick AFB, FL manages the contract (FA7022-11-C-0010).

Raytheon’s April 25/11 release placed the contract total at up to $65 million, but discussions with Raytheon confirmed that their figure included the 4 option years, as well as the initial base year announced by the Pentagon.

The AN/FPS-108 Cobra Dane radar sits on Shemya island in the Alaskan Aleutians. It has a face nearly 100 feet in diameter, and plays a number of key roles within the USA’s advanced long range radar network. One of its most important “tasked data collection opportunities” is its constant monitoring of Russia’s Kamchatka peninsula and Kura ballistic missile test range, hence that 100% requirement. Other key missions include monitoring the growing space hazard of orbital debris, and missile defense monitoring for NORAD and the US Missile Defense Agency.

PanSTARRS: Astronomy & Asteroid Assessment

Bruce Willis missed…

Kirkland AFB, NM recently entered into a cooperative effort with the University of Hawaii of Honolulu, Hawaii under the Panoramic Survey Telescope and Rapid Response System (PanSTARRS) multi-year program.

PanSTARRS will address numerous science applications ranging from the structure of the Solar System to the properties of the Universe of the largest scales. It will also be able to detect and catalog large numbers of earth-orbit crossing asteroids, or near earth objects (NEO) that present a potential threat to mankind. That last component to the mission is especially intriguing, as there is a long history of partial efforts in this direction within the US and elsewhere. So, where does this award fit in?

Modular Space: DARPA’s F6 Program

System F6 concept

Satellites are currently big, expensive to build and launch, vulnerable, impossible in practice to upgrade on-orbit, difficult to replace – and critical to military effectiveness. That’s a really bad combination. Now add program risk and cost inflation driven by those issues, as the military tries to launch the most advanced technologies it can, in a uniquely ‘no fail’ environment.

DARPA’s System F6 program aims at nothing less than a revolution in satellite technology, aimed at removing those constraints. If successful, it will develop and demonstrate the basic building blocks of a totally new space architecture, in which traditional integrated satellites are replaced by clusters of smaller, cheaper, wirelessly-interconnected space modules that form a “virtual” satellite.
