Title: LIVE: Atlas V - AEHF-3 - September 18, 2013
Post by: jacqmans on 07/28/2013 10:56 am
Lockheed Martin delivered the third Advanced Extremely High Frequency (AEHF) satellite to Cape Canaveral Air Force Station this month. It is scheduled to launch in September, joining two other AEHF satellites in the constellation providing protected communications for the U.S. and allies.

According to Spaceflight Now's launch scheduled (http://www.spaceflightnow.com/tracking/index.html (http://www.spaceflightnow.com/tracking/index.html)), the launch has been moved up by a whole week! It's now scheduled on September 18 at 3:04 - 5:04 am EDT (07:04 - 09:04 UTC), i.e. less than 16 hours after the launch of Cygnus!

With this launch, Cygnus demo, F9 v1.1 / CASSOIPE, DIV-H / NROL-65 and Minotaur V / LADEE all to happen within 3 weeks, it's the ultimate American Launch Fever TM!  ;D

Well, I suppose one comsat is more or less the same as another.  Mostly, the launches of non-exploration missions rarely get much publicity unless something goes wrong.  If CASSIOPE gets any publicity outside of the industry press, it will be because SpaceX will be identifying Falcon-9 v.1.1 as a 'future human launch vehicle' and a 'future reusable spacecraft'.

This is supposed to now launch 1 day after Antares. I assume some of the range assets that will be following Antares during ascent will also be used for tracking this bird. Does that mean Antares could get bumped if the Air Force wants their bird launched on time (even if 1 week early) ?

Title: Lockheed Martin-Built Advanced Extremely High Frequency Satellite Encapsulated For Upcoming Launch

Date: 11-Sep-2013 1:16 PM

CAPE CANAVERAL AIR FORCE STATION, Fla., Sept. 11, 2013 - The third Advanced Extremely High Frequency (AEHF) satellite built by Lockheed Martin [NYSE: LMT] has been encapsulated into its payload fairing in preparation for a Sept. 18 liftoff aboard an Atlas V rocket from Cape Canaveral Air Force Station , Fla.

The AEHF system is the nation's only protected strategic and tactical satellite communications program. It works in concert with its predecessor, Milstar, for global coverage. Lockheed Martin is under contract to deliver six AEHF satellites and the Mission Control Segment. Both AEHF-1 and AEHF-2 are on orbit, and AEHF-4 is progressing on schedule.

"The AEHF team has done excellent work to increase capability and affordability," said Mark Calassa , vice president for Protected Communication Systems at Lockheed Martin . "Our efforts were rewarded in December with a new Air Force contract for space vehicles 5 and 6. As we transition to fixed price, we are reducing risk to the customer and lowering satellite cost by over 30 percent with this recent block buy."

AEHF 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 . Canada was the first of these nations to connect to AEHF during tests with multiple terminals.

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; Netherlands Makes Call On Protected Communications Satellite

Date: 12-Sep-2013 9:10 AM

SUNNYVALE, Calif. , Sept. 12, 2013 - 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.

United Launch Alliance Marks 75th Successful Launch by Delivering the

Advanced Extremely High Frequency-3 Satellite to Orbit for the U.S. Air Force

 

ULA Completes Four Launches on Two Coasts in Just Two Months

 

Cape Canaveral Air Force Station, Fla., (Sept. 18, 2012) – A United Launch Alliance (ULA) Atlas V rocket carrying the Advanced Extremely High Frequency-3 (AEHF-3) satellite for the United States Air Force lifted off from Space Launch Complex-41 here at 4:10 a.m. EDT today. This was ULA’s 9th launch of an ambitious 12 mission schedule for the year and marks the 40th Atlas V mission and the 75th launch for ULA.

"The United Launch Alliance team is proud to serve alongside our mission partners and privileged that the Air Force has entrusted the ULA team to deliver the critical national security capabilities provided by AEHF-3 to orbit for our soldiers, sailors, airman and Marines around the world,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs. 

This mission was launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) 531 configuration vehicle, which includes a 5-meter diameter RUAG Space payload fairing along with three Aerojet solid rocket motors attached to the Atlas booster. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by a single Aerojet Rocketdyne RL10A engine.

“Today’s successful launch was the 75th since ULA was formed nearly seven years ago, the 40th Atlas V mission, and the fourth ULA launch in the last two months,” said Sponnick.  “The ULA team and our many mission partners emphasize a one-launch-at-a-time focus on mission success along with a strong commitment to continuous improvement – these elements together are the keys to launching our customer’s missions successfully at this unprecedented tempo in a reliable and cost-effective manner.”

The AEHF constellation is a joint-service satellite communications system that will provide survivable, global, secure, protected and jam-resistant communications for high-priority military ground, sea and air assets.

Developed by the United States Air Force to provide assured access to space for Department of Defense and other government payloads, the EELV Program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems. 

ULA's next launch is the Delta IV GPS IIF-5 mission for the Air Force scheduled Oct. 17 from Space Launch Complex-37 at Cape Canaveral Air Force Station, Fla.

ULA program management, engineering, test, and mission support functions are headquartered in Denver, Colo.  Manufacturing, assembly and integration operations are located at Decatur, Ala., and Harlingen, Texas. Launch operations are located at Cape Canaveral AFS, Fla., and Vandenberg AFB, Calif.

For more information on ULA, visit the ULA website at www.ulalaunch.com, or call the ULA Launch Hotline at 1-877-ULA-4321 (852-4321). Join the conversation at www.facebook.com/ulalaunch and twitter.com/ulalaunch.

News Release Issued: Sep 18, 2013 (7:09am EDT)

ATK Composite Technologies Support Satellite Launch
Event Marks Fifth Successful Flight for Atlas V Retro Motors Built by ATK

ARLINGTON, Va., Sept. 18, 2013 /PRNewswire/ -- ATK (NYSE: ATK) provided hardware for both the Advanced Extremely High Frequency (AEHF) 3 satellite and the United Launch Alliance (ULA) Atlas V launch vehicle that launched today from Cape Canaveral Air Force Station, Fla.

The AEHF 3 is the third satellite in a constellation designed to provide highly secure communications for the military and executive government users for in U.S. and three allied nations. Lockheed Martin Space Systems (NYSE:LMT) is the prime contractor for the AEHF constellation, which will complement and replace the Milstar system.

"Ensuring successful Atlas V missions is a critical component of what we do to support ULA," said Joy de Lisser, vice president and general manager of ATK Aerospace Structures. "Our workforce is committed to providing quality components to ULA and serving the U.S warfighter."

The Atlas V rocket flew in the 531 vehicle configuration with a five-meter fairing, three solid rocket boosters and a single-engine Centaur upper stage. This is the 40th Atlas V launch using ATK-built composite structures.

Many ATK components and structures also supported the Atlas V rocket:

•Using advanced fiber placement manufacturing and automated inspection techniques, ATK produced three components for the ULA Atlas V 531 vehicle, including the 10-foot diameter composite heat shield that provides essential protection to the first stage engine, the Centaur Interstage Adapter (CISA) that houses the second stage engine, and the Boattail that adapts from the core vehicle to the five-meter diameter fairing. ATK manufactured the structures at its Iuka, Miss., facility.
•This flight marked the fifth successful flight of the ATK retro motors. Eight of these solid motors supported separation of the spent first stage. The Atlas retrorocket is built at ATK's Missile Defense and Controls facility in Elkton, Md.
•ATK manufactured the Reaction Control System propellant tank for the Atlas V at its Commerce, Calif., facility.
For the AEHF 3 satellite, ATK provided a host of products:

•The spacecraft bus structure, solar array substrates, yokes and booms were manufactured by ATK's Space Components division, headquartered in San Diego, Calif.
•Composite structures for the antenna gimbal assemblies, used for precise pointing of the antenna payloads, were manufactured at ATK's Magna, Utah, facility.
•Pressurant and propellant tanks for the AEHF propulsion system were manufactured at ATK's Commerce, Calif., facility.
•ATK also provided the heat pipes in support of the bus structure and the payload heat pipes used for cooling the antenna payload suite; both were manufactured at the company's Beltsville, Md., facility.

U.S., ALLIES increase protected military satellite communications capability with aehf launch

Third Satellite Joins Advanced Extremely High Frequency Constellation

CAPE CANAVERAL AIR FORCE STATION, Fla., Sept. 18, 2013 – The third Advanced Extremely High Frequency (AEHF) military communication satellite, built by a Lockheed Martin [NYSE: LMT] 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.

Headquartered in Bethesda, Md., Lockheed Martin is a global security and aerospace company that employs about 116,000 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 2012 were $47.2 billion.

This might be of interest.

The object was spotted by staff from the Sydney Observatory, Sydney NSW Australia (mentioned in a previous post). They put out a post on facebook for people to have a look around 09:35 UTC.

The link contains photos taken from (I believe) a location some distance north of Sydney. I also heard it was seen from Brisbane Qld Australia. So it must have been high up.

4 SOPS assumes control of third AEHF satellite

3/27/2014 - SCHRIEVER AIR FORCE BASE, Colo.  -- The 4th Space Operations Squadron accepted satellite control authority of the third Advanced Extremely High Frequency satellite here March 21.

The MILSATCOM Program Office, a division of the Space and Missile Systems Center in Los Angeles, has held SCA of the spacecraft, known as AEHF-3, since its launch Sept. 18.

Robert Tarleton, director of MILSATCOM systems directorate, started the transfer ceremony by handing control authority to the 50th Space Wing via the 14th Air Force.

Col. Tommy Roberts, 50th Operations Group commander, accepted SCA then promptly delegated command and control of the vehicle to 4 SOPS and its Commander, Lt. Col. Monte Munoz.

"When I was in 4 SOPS we spent a lot of time preparing for AEHF, but I never saw a launch," said Roberts, a former 4 SOPS commander. "So, it's special for me to be here and witness this success. Congratulations to the entire AEHF team."

AEHF-3 represents the next-generation follow-on satellite to the Milstar protected communications constellation and is designed to augment and improve Milstar's capabilities. It will provide survivable, global, secure, protected and jam-resistant communications for high-priority military ground, sea and air assets.

Users include National Security Council members and unified combatant command commanders who control tactical and strategic forces at all levels of conflict, as well as international partners. Nearly identical to AEHF-1 and AEHF-2, it has eight times the capacity of a Milstar vehicle and is designed to perform its mission for 14 years.

Following a four-month journey, AEHF-3 reached geosynchronous orbit in January. Since then, 4 SOPS members have been testing the satellite alongside SMC personnel.

Testing included transmitting an extended-data-rate signal through an AEHF vehicle to other AEHF vehicles, something that wasn't possible with just two AEHF satellites on orbit.

Using XDR, AEHF satellites can transmit data at speeds much faster than legacy Milstar vehicles, allowing users to potentially communicate via video conference.

"Having three AEHF vehicles on orbit basically extends our footprint of XDR capabilities," said Lt. Col. Alistair Funge, 4 SOPS operations officer. "The operational position of the satellite, and hence its coverage area, is up to U.S. Strategic Command. We are prepared to support users and the combatant commands' needs wherever the satellite is finally positioned."

As part of the brief ceremony, Munoz informed the squadron that it officially held responsibility for AEHF-3.

"This was an awesome job by the entire team getting AEHF-3 to this point," he said.

The fourth AEHF vehicle is tentatively scheduled for launch in 2015

This is more about the AEHF network in general.

Quote
WASHINGTON — The United Kingdom has officially connected with the advanced extremely high frequency (AEHF) protected satellite communications network, becoming the last partner nation on the program to go operational.

The news was announced in a Tuesday release by AEHF contractor Lockheed Martin, although the first connection was made by the UK in February. Testing has been ongoing since then, with both ground- and sea-based terminals.

The US and UK are joined by Canada and The Netherlands as partners on the AEHF system. Canada connected to the system in May of 2013, followed two months later by the Dutch. In April of this year, all four countries participated in joint tests to make sure the system could successfully interconnect.

Australia was not part of the test? I thought they paid for one of the platforms.

AEHF Achieves Initial Operational Capability

Posted 7/30/2015   Updated 7/30/2015

7/30/2015 - LOS ANGELES AIR FORCE BASE, Calif -- General John Hyten, Air Force Space Command commander, declared Initial Operational Capability for the Advanced Extremely High Frequency system on July 28.  This significant achievement reflects superb collaboration between numerous organizations, including Headquarters Air Force Space Command, the Space and Missile Systems Center, U.S. Army, U.S. Navy and the developers, Lockheed Martin and Northrup Grumman. Advanced EHF also includes International Partners from the United Kingdom, Canada and the Netherlands.

The AEHF system is a joint service satellite communications system that provides survivable, global, secure, protected, and jam-resistant communications for high-priority military ground, sea and air assets.  AEHF provides 10 times the throughput and a substantial increase in coverage compared to the 1990s-era Milstar satellites currently in orbit.

"Achieving AEHF IOC is a great accomplish for the team. We're proud to deliver an unparalleled leap forward in protected communications capability for both our nation's senior leaders and also our warfighters in the field," said Lt. Gen. Samuel Greaves, Space and Missile Systems Center's commander.

With the IOC declaration, the Air Force's 4th Space Operations Squadron is now operating the AEHF system, supporting warfighters around the world.

The first AEHF spacecraft was launched on Aug. 14, 2010; the AEHF-2 spacecraft was launched on May 4, 2012; and the AEHF-3 spacecraft was launched on Sept. 18, 2013.  The Air Force will continue to expand the AEHF constellation to meet the demands of the DoD and the warfighter.  AEHF-4, AEHF-5, and AEHF-6 are projected to launch in 2017, 2018, and 2019 respectively.
