Is the Pentagon Losing the Arms Race in Space?

 

March 18, 2015 By Franz-Stefan Gady – The Diplomat

 

Pentagon officials are deeply worried about Chinese and Russian anti-satellite weapons. Are their concerns justified?

 

This year, the Pentagon will try to step up its weapons modernization programs and boost investments in cutting-edge defense technology. As the principal rationale behind the Pentagon’s push, top Department of Defense officials cite the fear that the United States will lose its relative technological superiority thanks to the burgeoning technical capabilities of the Chinese and Russian militaries .

Yesterday, speaking at the McAleese/Credit Suisse Defense Programs Conference, Robert O. Work, deputy U.S. secretary of defense, noted that “because of budget uncertainty and restrictions imposed by Congress, and because of our unrelenting focus on the readiness of forward deployed forces, we’re chronically underinvesting in new weapons and capabilities.”

He further emphasized, “That should give all of us pause because our technological dominance is no longer assured (…) We see several nations developing capabilities that threaten to erode our long-assured technological overmatch and our ability to project power.” Chinese and Russian growing military capabilities are  particularly worrisome for the Pentagon’s leadership.

The American military’s chief weapons buyer, Under Secretary of Defense for Acquisition, Technology and Logistics Frank Kendall, said during his presentation at the conference that the erosion of the U.S. technological edge in the space domain is “particularly bad” due to Chinese and Russian growing anti-satellite capabilities.

These capabilities potentially include cyber and electromagnetic attacks, jamming operations, and ground-based lasers as well as anti-satellite (ASAT) missiles. For example, China destroyed a defunct weather satellite with a missile in 2007. In addition, Beijing tested a missile-fired anti-satellite kill vehicle in the summer of 2014, disguising it as a ballistic missile defense test. Russia is allegedly developing a satellite hunter — a spacecraft able to track enemy satellites and destroy them — according to media reports.

U.S. officials are especially concerned about threats to U.S. Advanced Extremely High Frequency (AEHF) satellites. “If an adversary were to take out one, just one satellite in the constellation, a geographic hole is opened and we potentially have a situation where the president can’t communicate with forces in that part of the world,” one official underlined.

However, many analysts note that the current threat scenarios have much more to do with the ongoing debate about sequestration — across the board budget cuts — and the fiscal year 2016 defense budget request (see: “The Defense Budget Debate Rages On”) than the actual danger to U.S. satellites from Chinese and Russian weapons.

As Diplomat contributor Jaganath Sankaran noted back in 2014: “While these concerns have some validity, all U.S. military satellites are not equally vulnerable to a Chinese ASAT attack. Furthermore, the benefits from an ASAT attack are limited and would not confer decisive military advantage in every plausible conflict.”

“The substantial range of orbital altitude — 1,000 kilometers to 36,000 kilometers — from which satellites operate poses a challenge to China’s ability to attack U.S. military satellites (…) Unlike the U.S., China has a very limited satellite tracking capability, most of which are based in its territory and possibly a few ships,” he adds.

More importantly he emphasized that “the presence of alternate platforms and built-in redundancies substantially limit the advantages that China can obtain from anti-satellite operation against the U.S.”

In November 2014, the Pentagon launched the Defense Innovation Initiative (DII), an initiative to maintain America’s military dominance for the 21st century and to develop a new third offset strategy. “The DII’s leading focus is to identify, develop and field breakthrough technologies and systems and to develop innovative operational concepts to help us use our current capabilities in new and creative ways,” Deputy Secretary Work said.

Ultra-Secure AEHF Satellites Connect United Kingdom Users for First Time

U.S., Canada, The Netherlands, U.K. Begin Coalition Testing

 

SUNNYVALE, Calif., June 10, 2014 – Lockheed Martin

 

All partner nations are now using the Advanced Extremely High Frequency (AEHF) protected communications satellite system after the United Kingdom connected earlier this year. Four nations will use the Lockheed Martin-produced [NYSE: LMT] satellites for their most important transmissions, from commanders-in-chief to troops in the field.

 

The U.K. connection follows Canada’s first successful call in May, 2013, and The Netherlands’ initial connection came two months later. Over the past year AEHF facilitated many connections between international users, and U.S.-led tests in April included all four partners.

 

“AEHF is a keystone in global security. It is the only system that can provide highly-protected communications, circumventing our adversaries’ jammers in most wartime operations,” said Mark Calassa, vice president of Protected Communication Systems at Lockheed Martin. “We are committed to driving this capability forward. All four partners are connected, and we are marching steadily toward Multi-Service Operational Test and Evaluation.”

 

U.K. armed forces started to connect over the course of several weeks beginning Feb. 25. They used two terminal variants to communicate with AEHF-2: One made for connections on land and another designed for users at sea. Service members contacted the satellite at Colerne Airfield, Wiltshire, with the shore variant of the Navy Multiband Terminal (NMT). In separate tests, U.K. users connected via the NMT ship variant from Telemetry & Command Station Oakhanger, Hampshire.

 

“AEHF not only delivers higher-bandwidth communications for the U.K., it makes communications with allies faster and easier,” Calassa said. “AEHF is showing it can handle the demands of protected coalition communications at high speeds, connecting nations with their own users and allied users across the globe.”

 

The four-nation AEHF program is led by the U.S. Air Force Space and Missile Systems Center at Los Angeles Air Force Base, California. Lockheed Martin is under contract to deliver the Mission Control Segment and six AEHF satellites, which are assembled at the company’s Sunnyvale, California, facility.

 

Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 113,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation’s net sales for 2013 were $45.4 billion.

Fourth AEHF Protected Communications Satellite Begins Integration Months Ahead of Schedule


SUNNYVALE, Calif., April 8, 2014 – Lockheed Martin

 

The fourth Advanced Extremely High Frequency (AEHF) satellite produced by Lockheed Martin [NYSE: LMT] is taking shape after early deliveries of its payload and propulsion core. AEHF-4, expected to launch in 2017, will enable the constellation to reach full operational capability.

The propulsion core manufactured by Lockheed Martin and payload produced by Northrop Grumman arrived at the AEHF integration facility in Sunnyvale, Calif., earlier in the year. Both were delivered significantly ahead of baseline schedule. The propulsion core arrived eight months early, and the payload arrived two months early.

“We’re driving a shorter timeline for bigger cost savings. In fact, we are putting plans in place to finish six months ahead of our baseline schedule,” said Mark Calassa, vice president of Protected Communication Systems at Lockheed Martin. “AEHF’s propulsion system reflects Lockheed Martin’s investment in more efficient spacecraft. To complement its traditional chemical propulsion, AEHF uses the highest power electric propulsion system ever flown for orbit raising and station keeping.”

Lockheed Martin is under contract to deliver six AEHF satellites and the mission control segment. Users are testing AEHF-1, AEHF-2 and AEHF-3 on orbit, and the fourth satellite will enable the system to reach full operational capability. The fifth and sixth satellites will add to the capacity of the operational system and are being assembled at Lockheed Martin.

AEHF is the most secure communications satellite system used by the U.S. government. Its jam-resistant communications are resilient against enemy forces, including nuclear attack, and a single AEHF satellite provides greater capacity than its compatible legacy five-satellite Milstar system. AEHF’s five-fold increase in data rates speed up protected communications, such as real-time video, battlefield maps and targeting data. The constellation serves troops and national leaders, including the president and Pentagon officials.

 

Headquartered in Bethesda, Md., Lockheed Martin is a global security and aerospace company that employs approximately 115,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation’s net sales for 2013 were $45.4 billion.

USAF Launches Third Advanced Extremely High Frequency Satellite

Sep 18, 2013  (SPX)

 

Cape Canaveral AFS FL - The third Advanced Extremely High Frequency (AEHF) military communication satellite, built by a Lockheed Martin team for the U.S. Air Force, was successfully launched today at 4:10 a.m. from Cape Canaveral Air Force Station aboard a United Launch Alliance (ULA) Atlas V rocket. Lockheed Martin confirmed signal acquisition at 51 minutes after launch.

 

The AEHF system provides vastly improved global, survivable, highly secure, protected communications for strategic command and tactical warfighters operating on ground, sea and air platforms.

 

The system also serves international partners including Canada, the Netherlands and the United Kingdom.

 

"The successful launch of the third AEHF satellite is a significant accomplishment for the nation's protected communications mission," said Mark Calassa, vice president of Protected Communication Systems at Lockheed Martin.

 

"AEHF is functioning well in tests, and allies are connecting to the system for the first time. It shows that our product is meeting mission needs, and we have room to expand capacity for both tactical and strategic users in the future."

 

AEHF takes advantage of several Lockheed Martin capabilities to deliver six satellites and a mission control segment. Lockheed Martin contributed payload system engineering, mission control ground software, solar arrays and the A2100 spacecraft bus, which is a dependable and low-risk platform for commercial, civil and military satellites.

 

Both AEHF-1 and AEHF-2 are on orbit, and AEHF-4 through -6 are progressing on schedule. All satellites are assembled at the company's Sunnyvale, Calif., facility.

 

A single AEHF satellite provides greater total capacity than the entire legacy five-satellite Milstar constellation. Individual user data rates will increase five-fold, permitting transmission of tactical military communications, such as real-time video, battlefield maps and targeting data.

 

In addition to its tactical mission, AEHF provides the critical survivable, protected and endurable communications links to national leaders, including presidential conferencing in all levels of conflict.

AEHF Expands Global Communications for Allied Missions

Sep 12, 2013 ASDNews Source : Lockheed Martin Corporation

 

    Netherlands Makes Call On Protected Communications Satellite

 

The Netherlands has become the second Advanced Extremely High Frequency (AEHF) international partner to communicate using the Lockheed Martin-produced [NYSE: LMT] satellite system. During July testing, for the first time three nations used the system simultaneously as The Netherlands connected to U.S., Canadian and domestic terminals.

 

AEHF provides vastly improved global, survivable, jam-proof, protected communications for strategic and tactical users on ground, sea and air platforms.

 

“AEHF’s ability to securely connect allies together is vital to current and future operations,” said Mark Calassa, vice president of Protected Communications Systems at Lockheed Martin. “We are hard at work delivering this global capability: Our fixed-price production builds are on schedule, we will launch a third satellite next week, and those users testing the system are extremely satisfied with this leap forward in capability.”

 

The U.S.-Canada-Netherlands team engaged AEHF-1 and AEHF-2 while completing test calls between international terminals. In separate tests, Dutch forces exchanged voice and data communications with the U.S. and Canada by connecting to the AEHF-2 satellite, crosslinking with AEHF-1 and downlinking to the U.S. Navy terminal in San Diego and a Canadian terminal at Shirley’s Bay, Ontario. By connecting with AEHF-2, The Netherlands also completed their first local AEHF call from ship to shore. Radios used in the tests include domestic and international versions of the Navy Multi-Band and Secure Mobile Anti-Jam Reliable Tactical (SMART-T) terminals.

 

The U.S. Air Force has been allowing select groups to use AEHF for testing as it fields the system, and the system has performed well as its user base grows with different terminal types. The Netherlands achievement follows Canada’s successful call in May. Both countries will continue testing for several months as they move toward initial operational capability. The United Kingdom is also scheduled to complete their first connection by the end of the year.

 

A single AEHF satellite provides greater total capacity than the entire legacy five-satellite Milstar constellation. Individual user data rates will increase five-fold, permitting transmission of tactical military communications, such as real-time video, battlefield maps and targeting data. In addition to its tactical mission, AEHF provides the critical survivable, protected and endurable communications links to national leaders, including presidential conferencing in all levels of conflict.

 

Lockheed Martin is under contract to deliver six AEHF satellites and the Mission Control Segment. Both AEHF-1 and AEHF-2 are on orbit, AEHF-3 was shipped for a September 18 launch and AEHF-4 is progressing on schedule. All satellites are assembled at the company’s Sunnyvale, Calif., facility.
