BAE Systems PLC (London: BAES) and L3Harris Technologies Inc. (NYSE: LXH) delivered the first of 10 EC-37B Compass Call aircraft to the U.S. Air Force for formal combined developmental and operational testing. The next-generation system evolves the Air Force’s 40-year mission of employing electromagnetic attack (EA) capabilities in support of U.S. and coalition air, surface, and special operations forces.
Mission system prime BAE Systems produces the Compass Call Airborne Electromagnetic Attack mission system at its Hudson, New Hampshire facility. The system disrupts enemy communications, radars and navigation systems, and suppresses enemy air defenses by preventing the transmission of essential information between adversaries, weapon systems and command-and-control networks.
Platform integration prime L3Harris integrated the EC-130H Compass Call mission system into a modern Gulfstream G550 business jet at its Waco, Texas aircraft missionization center. The EC-37B has increased speed, endurance and high-altitude operation for improved survivability and range to deliver EA effects.

Porter Airlines has unveiled plans to extend its award-winning service to destinations throughout North America with a firm order for 30 Embraer E195-E2 jets, with purchase rights for a further 50 aircraft. The deal will be included in Embraer’s second quarter backlog, and is worth USD5.82 billion, at list price with all options exercised. First revealed in May 2021, this announcement adds the purchase rights and the customer name, which had been undisclosed.
Porter Airlines will be the North American launch customer for Embraer’s newest family of jets, the E2. Porter’s investment is set to disrupt the Canadian aviation landscape; enhancing competition, elevating passenger service levels and creating as many as 6,000 new jobs. Porter intends to deploy the E195-E2s to popular business and leisure destinations throughout Canada, the United States, Mexico and the Caribbean, from Ottawa, Montreal, Halifax and Toronto Pearson International Airport.
Porter’s first delivery and entry into service is scheduled starting in the second half of 2022. The option to convert purchase rights to the E190-E2s is included in the agreement. This would provide greater flexibility to introduce non-stop service in markets with fewer passengers, and to add frequencies on higher demand routes.
The E195-E2 accommodates between 120 and 146 passengers. Configuration plans for Porter’s E2s will be revealed in due course.
Currently traveling at some 105 million kilometres from Earth, the Airbus-built Solar Orbiter (SolO) is en route for an encounter to uncover the secrets of our closest star.
While humankind has been studying the Sun for hundreds of years, the research is limited because data was always collected from distances more or less equal to the star’s separation from Earth, according to Ian Walters, Airbus’ SolO Project Manager.
“Solar wind takes about two to four days to get from the Sun to Earth, and in that time, it transforms completely,” he explained. “We can better correlate what is seen with what is felt from the Sun if we can get up close. That’s the point of the Solar Orbiter mission…and it’s never been achieved before.”
Solar Orbiter was launched in February in a joint mission of the European Space Agency and the U.S. National Aeronautics and Space Administration. Travelling closer to the Sun than its nearest planet – Mercury – SolO will make comprehensive measurements of the nascent solar wind.
Beating the heat
For the spacecraft and its 10 instruments to survive extreme temperatures of up to 600 deg. Centigrade, Airbus designed a protective heat shield with openings for SolO’s five telescopes to peek through during the trek.
According to Walters, the most critical heat protection technology is the Stand-off Radiator Assembly (SORA) – a set of radiators sitting on the spacecraft’s side that is always in shadow, enabling them to quickly transfer heat from the instruments into space. SORA’s thermal straps are made from pyrolytic graphite, which is five times more conductive than copper wire but flexible like paper.
To avoid any molecular contamination that could compromise imagery from the telescopes, Airbus also built Solar Orbiter to levels of cleanliness far exceeding any other spacecraft built in the UK to date. Every item on SolO has been heated to over 120 degrees to make sure no gases are emitted in the vacuum of space.
Predicting solar events
Data from Solar Orbiter can help make significant improvements to everyday life, particularly when it comes to predicting solar flares and coronal mass ejections (CME) – the expulsions of plasma and its accompanying magnetic field from the sun, which can have a major impact on Earth.
“In 1859, one such episode took down the world’s telegraph network,” Walters said. “A similar event today would severely disrupt our power grids, mobile phone towers, navigation systems and many other critical technologies.”
He added: “If we could predict the CME was coming our way, we’d have about two days’ notice for emergency government committees to be activated and react, instead of the few minutes’ notice we receive today.”
LONDON, Aug 23 (Reuters) – British Airways pilots are to go on strike for three days in September, their union said on Friday, in a dispute over pay that could disrupt the peak summer holiday season.
Last month, the pilots overwhelmingly voted for industrial action and the airline, which is part of IAG, failed in a court bid to stop them.
“The British Airline Pilots Association (BALPA) has today given notice to British Airways that it will call on its members to strike on 9th, 10th and 27th September 2019,” the union said in a statement.
“It is clear, following discussions with members over the last few days, that BA’s most recent offer will not gain the support of anywhere near a majority of its pilots.”
British Airways said the strike action was unjustifiable as their pay offer was fair and that the strikes would destroy the travel plans of tens of thousands of customers.
“We are now making changes to our schedule. We will do everything we can to get as many people away on their journeys as possible,” the airline said in a statement.
“However, it is likely that many of our customers will not be able to travel and we will be offering refunds and re-bookings for passengers booked on cancelled flights.”
The airline said it was exploring options to supplement its fleet with aircraft and crew from other airlines, known as wet-leasing, and working with partner airlines to schedule larger aircraft to take more customers.
