U.S. Space Command is warning that the remnants of the massive Chinese rocket that was shot into space last Sunday will likely fall to Earth soon, perhaps as early as July 31.

The 10-storey, 21-tonne rocket was part of the Wentian space station module and docked with the country’s Tiangong space station this week.

The uncrewed craft was blasted to space by a Long March 5B rocket from the Wenchang launch centre on the Chinese island of Hainan.

The big problem, however, is that experts aren’t sure how much of the rocket will survive and, most concerning, they don’t know where it’s expected to crash-land

Evidently everyone held their breath, crossed their fingers and all worked out.

Updated Timeline for ADS-B Performance Mandate in Canada

nav-canada-logo-e1587425795708.jpg?w=204

OTTAWA, ON, Aug. 2, 2022 /CNW/ – NAV CANADA today confirmed that due to supply chain impacts related to the COVID pandemic, the previously announced implementation dates for the Automatic Dependent Surveillance – Broadcast (ADS-B) Out Performance Mandate have been adjusted for Class A and B airspace.

In coordination with Transport Canada, the state regulator, new dates have been developed in a manner reflective of customer feedback regarding supply chain limitations and backlogs to acquire and install the appropriate transponder, as well as current equipage levels in each class of airspace.

As a result, the mandate will come into effect as follows:

  • Class A Canadian airspace on August 10, 2023
  • Class B Canadian airspace on May 16, 2024
  • Class C, D and E to occur no sooner than 2026 and will be determined pending further assessment.

In February 2022, NAV CANADA announced Canada’s plan to implement ADS-B Out mandate to enhance aircraft operations in domestic airspace – requiring aircraft operators flying in certain domestic airspace to meet ADS-B Out Performance Requirements.

Following the announcement and after considerable industry engagement with Transport Canada and industry stakeholders, NAV CANADA is confirming new official start dates to allow customers adequate time to equip.

“The valuable input we have received from our stakeholders and partners on the Canadian ADS-B mandate indicates that later dates for the mandate requirement are warranted as the industry continues to navigate the ongoing impacts to supply chains due to the pandemic,” said Jeff Dawson, Assistant Vice President, Operational Support. “We are taking these steps to ensure customers have adequate time to comply with mandate equipage requirements.”

“What we are seeing in terms of equipage is very encouraging – rates in Class A airspace are at 95 per cent, while those in Class B airspace are above the 88 per cent mark and growing steadily.”

The equipage requirements of Canada’s approach to the implementation of the ADS-B are in line with a growing number of other countries in the world, and the adoption of satellite-based surveillance technology ensures long-term alignment with the global aviation system.

About the ADS-B Out Performance Requirements Mandate

To meet the ADS-B Out Performance Mandate, aircraft will be required to:

  • Be equipped with an appropriate transponder with ADS-B out capabilities and performance with the applicable standard of Radio Technical Commission for Aeronautics (RTCA) DO-260B, “Minimum Operational Performance Standards”, or newer.
  • Have antenna capability for broadcast toward space-based ADS-B receivers emitting 1090 MHz extended squitter. This requirement can be met either through antenna diversity (the use of a top and bottom antenna) or with a single antenna that is capable of transmitting both towards the ground and up towards satellites.

How L3Harris created US special operators’ new plane to hunt and strike terrorists

 Aug 2, 03:51 PM The L3Harris Sky Warden will be used to pressure terrorist groups in places like Africa, where airspace is largely permissive. (L3Harris)

WASHINGTON — U.S. Special Operations Command’s new Armed Overwatch aircraft will be able to carry multiple weapons configurations and modular sensors that can be quickly swapped out as well as be disassembled for deployment within hours.

The AT-802U Sky Warden, made by L3Harris Technologies and aircraft manufacturer Air Tractor, is SOCOM’s pick for a rugged plane that can carry out intelligence, surveillance and reconnaissance, close air support, and strike missions against terrorist groups in austere locations such as parts of Africa.

In an interview with Defense News on Tuesday, Luke Savoie, president of L3Harris Technologies’ ISR sector, said the company’s use of model-based engineering and modular open systems allowed it to design a low-cost aircraft tailored to deliver what special operators need in the field.

SOCOM wants Armed Overwatch planes so it can continue to pressure extremist groups, such as Somalia’s al-Shabab, in areas with largely uncontested airspace, while the Air Force shifts its primary focus and more elaborate fighters and bombers toward potential high-end threats in Europe and Asia.

Armed Overwatch planes could also take over at least some of the missions carried out by the U-28 Draco ISR aircraft, which is aging and expensive to maintain.

L3Harris’ indefinite delivery, indefinite quantity contract to deliver as many as 75 Sky Wardens will be worth up to $3 billion, with an initial contract award for $170 million.

The trust factor

L3Harris began work on what would eventually become the Sky Warden in March 2020, shortly after SOCOM released its Armed Overwatch solicitation. Savoie said the company started with “no preconceived notions.”

Rather than beginning with a list of must-haves for the airplane, as traditional requirements-based engineering might dictate, Savoie said L3Harris’s designers used model-based systems engineering to consider why a Sky Warden pilot might need certain capabilities and the best way to fill those needs.

L3Harris also sought to ensure the capabilities are tightly integrated to reduce the crew’s workload and take advantage of automation whenever possible, he said.

“In special ops, it comes down to that” trust, Savoie said. “The guy on the ground isn’t looking for dots on [a] map, on a tablet or something on his wrist. He’s looking for the confidence that someone talking in his ear knows what they’re talking about, and not having to second guess that.”

That led L3Harris to refine the kind of sensors and software this plane would need and how it would integrate the systems, he said. The company talked to those who have carried out this mission before to make the Sky Warden as user-friendly as possible.

“End users … constantly remind us, ‘I like to look through my gun sight, I don’t like to look at my arm, at a tablet,’” said Savoie, a former U-28 and AC-130 pilot.

Users also emphasized the importance of instant communication, with no latency, for an airplane carrying out an Armed Overwatch mission, Savoie said, as well as the need to streamline the information presented to the pilot.

To build the air frame that would become Sky Warden, L3Harris teamed up with Air Tractor, which typically builds agricultural and firefighting aircraft.

The company had worked with Air Tractor on previous programs, such as surveillance aircraft for Jordan in the mid-2010s and other projects involving sensor, weapons and software integration. But, Savoie said, with its added strike capabilities, Sky Warden was much more complicated than the Jordanian surveillance planes.

L3Harris created three prototype Sky Wardens. One was fully missionized, with all the modifications to do everything an operational Armed Overwatch plane would have to do. The company sent that prototype to Eglin Air Force Base in Florida last summer for SOCOM’s evaluation. Four other companies also demonstrated their prototypes to SOCOM in 2021 and early 2022.

A second prototype was built for L3Harris’s own flight tests and to qualify the plane’s autopilot. L3Harris also built a third Sky Warden prototype to test and certify the aircraft’s strengthened, high-load wing to ensure it could carry up to 6,000 pounds of external ordnance.

Savoie said Sky Warden can be easily prepared for deployment on a C-17 or C-5 mobility aircraft. The plane can be disassembled in about 7 hours, loaded on a cargo plane, and then reassembled in about the same amount of time once it’s reached its destination, he said. L3Harris brought a Sky Warden to May’s Special Operations Forces Industry Conference in Tampa, Florida, where it demonstrated how quickly the breakdown and reassembly process could take place.

“It’s a pretty compact form,” Savoie said.

The per-unit cost of a Sky Warden will vary depending on its configuration and capabilities, Savoie said, but declined to identify a figure.

L3Harris’ contract also includes providing training systems, mission planning systems, support equipment, spares and logistical support.

Air Tractor aircraft have carried weapons before, such as 50-caliber guns and 7.62 miniguns, Savoie said. The Sky Warden could be armed with six weapons stations, with the laser-guided 2.75-inch Advanced Precision Kill Weapon System, or APKWS, rocket being its primary weapon.

Sky Warden could also carry GBU-12 Paveway laser-guided bombs, Savoie said, and L3Harris is close to having it capable of carrying the AGM-114 Hellfire missile. And Sky Warden has the infrastructure to handle as many as eight common launch tube-based weapons such as the AGM-176A Griffin, he said.

Construction of the Sky Wardens will begin at Air Tractor’s Olney, Texas facility. Once those airframes are built, they will be shipped to L3Harris’s modification center in Tulsa, Oklahoma, where work to modify them for the Armed Overwatch mission will take place.

Savoie said L3Harris will manufacture parts for the modifications at its Greenville, Texas facility. L3Harris will also do software work for the plane at its Nashville, Tennessee facility, and sustainment activities will be done at Rockwall, Texas. Engineering work will be done at L3 locations in Waco, Greenville and Plano, Texas. Various other L3Harris sites will provide sensor, radio and weapons release capabilities, Savoie said.

Stephen Losey is the air warfare reporter at Defense News. He previously reported for Military.com, covering the Pentagon, special operations and air warfare. Before that, he covered U.S. Air Force leadership, personnel and operations for Air Force Times.

AFSOC hopes its Armed Overwatch plane will be able to pressure violent extremist groups in austere places like Africa, where the airspace is largely permissive.

Perhaps looking out of the forward starboard door to check the right landing gear?

It’s more likely that he was looking forward from the rear cargo door.
