Upgrading NORAD’s capabilities with AN/SPY-7(V)1 radar (aka “Aegis Ashore”)
Ted Campbell on the need to upgrade NORAD radar installations as part of a general refurbishment of the alliance’s capabilities:

Lockheed Martin’s Solid State Radar has been designated as AN/SPY-7(V)1 by the US government.
Image from Lockheed Martin/PRNewsfoto.
One of the elements which might be considered in modernizing and enhancing the North American Aerospace Defence Command (NORAD) surveillance, warning and control system is a new radar and some people have suggested that the AN/SPY-7(V)1 radar, sometimes called Aegis Ashore, might be a useful (and proven, it is in use, on land, in Japan, and will be fitted on Canada’s new Type 26 (destroyer-frigate) combat ships) solution. This radar is eminently suitable to be part of an enhanced (conventional) NORAD and of a CANUS continental ballistic missile defence system.
There are many technical (and logistical) advantages to using that radar on both our, Canadian, warships and in a land-based role, too.
The AN/SPY-7(V)1 radar produces a lot more information than do the current AN/FPS-117 and AN/FPS-124 radars which are used in the NORAD role, today, and were built in the 1980s using 1960s and ’70s technology.
(Please don’t worry about the AN/*** designations. They are part of a very sensible American system which was designed to make it simpler to identify both Army and Navy systems (hence the AN/ at the beginning). The three letters following the AN/ describe the system:
- The first letter describes the installation. F means Fixed, on the ground (land) and S means on a ship;
- The second letter means the type of equipment, and P means radar; and
- The third letter means purpose. S means search (detection and locating) and Y surveillance and control.
Thus the SPY-7 is a shipborne surveillance radar and the FPS-117 is fixed (land-based) search radar. The numbers just differentiate one system from another.)
If Canada chooses an advanced radar, like the SPY-7, two engineering problems will need to be addressed:
- First, these things use a lot more power than do the existing radars; and
- Second, they produce much, much more information which needs to be “transported” instantly, to control centres in places like Canadian Forces Base North Bay, where all the data from all the radars is analyzed and used to effect NORAD’s mission. If the radar sites are located below (about) 72°N, as would be the case for coastal radars in BC, NS and NL, this is not a huge problem because the station is within the “footprint” of the big, high bandwidth satellites in geostationary orbit. But if the radar site is too far North then a terrestrial (possibly microwave, maybe tropospheric scatter) network (in which each station needs electrical power, too) will have to be installed to move the data to a satellite ground station. (Or a non-geostationary, high bandwidth, satellite system will have to be deployed.)

QotD: The post-oil-crisis evolution of modern cars
Man I remember back in 1982, we all thought we’d be driving nothing but 3-cylinder diesels by the turn of the millennium. If you went back and told some gearhead in my high school class that in 2017 Dodge would be selling a “street legal” 10-second Hemi Challenger, he’d think you were talking about the 0-60 time of a 4-cyl car.
The computer changed everything. Not only in engine tuning and performance, but in design and modeling.
I had an example of a classic late Dark Ages car, an ’84 Trans Am with the LG4 305c.i. Rochester Quadrabog motor. A hunnert and fifty horsepower and nearly every engine function powered by enough dry-rotting vacuum tubing to reach to the moon and back…
Only a few years later and exotic computer-designed and controlled long-runner port fuel injection systems were common on domestic performance cars and HP numbers were on the right side of 200 for the first time in a decade.
It was coming out of an awful time. Like a friend wrote: When he went into seminary you could buy a Mustang with a nearly 400bhp engine option. When he left seminary, the Mustang was a Pinto.
Being a car enthusiast in America in the latter half of the 70s/first half of the ’80s was like being a dirt farmer in Fifth Century Britain, marveling at the weed-grown roads and disused aqueducts left by a race of giants and building your pig shed with stones looted from a burned library.

The reasons HMS Queen Elizabeth has two islands – Russia copied the twin island design
Military TV
Published 5 Jan 2020Many have wondered why HMS Queen Elizabeth has two “islands”. Here we consider why she is the first aircraft carrier in the world to adopt this unique arrangement and the benefits it brings.
REDUNDANCY AND SEPARATION CAN BE GOOD
In a moment of inspiration back in 2001, an Royal Navy officer serving with the Thales CVF design team developing initial concepts for what became the Queen Elizabeth class, hit upon the idea of separate islands. There are several advantages to this design but the most compelling reason for the twin islands is to space out the funnels, allowing greater separation between the engines below. Queen Elizabeth class has duplicated main and secondary machinery in two complexes with independent uptakes and downtakes in each of the two islands. The separation provides a measure of redundancy, it increases the chances one propulsion system will remain operational in the event of action damage to the other. Gas turbine engines (situated in the sponsons directly below each island of the Queen Elizabeth class) by their nature require larger funnels and downtakes than the diesel engines (in the bottom of the ship). The twin island design helps minimise their impact on the internal layout.In a conventional single-island carrier design, either you have to have a very long island (like the Invincible class) which reduces flight deck space or, the exhaust trunkings have to be channelled up into a smaller space. There are limits to the angles this pipework may take which can affect the space available for the hangar. The uptakes can also create vulnerabilities, the third HMS Ark Royal was lost to a single torpedo hit in 1941, partly due to progressive engine room flooding through funnel uptakes.
The twin island design has several other benefits. Wind tunnel testing has proved that the air turbulence over the flight deck caused by the wind and the ship’s movement, is reduced by having two islands instead of one large one. Turbulent air is a hindrance to flight operations and aircraft carrier designers always have to contend with this problem. Twin islands allow greater flight deck area because the combined footprint of the two small islands is less than that of a single larger one. By having two smaller islands it allowed each to be constructed as a single block and then shipped to Rosyth to be lifted onto the hull. The forward island was built in Portsmouth and the aft island built in Glasgow.
This arrangement solves another problem by providing good separation for the main radars. The Type 1046 long range air surveillance radar is mounted forward while the Type 997 Artisan 3D medium range radar is aft. Powerful radars, even operating on different frequencies, can cause mutual interference or blind spots if the aerials are mounted too close together. Apart from a slim communications mast, both the Artisan and 1046 have clear, unobstructed arcs.

The 2010s … the best decade (so far) in human history
Matt Ridley explains why, despite all the doom and gloom in the daily headlines, the last ten years have been the best by almost any measure:
Let nobody tell you that the second decade of the 21st century has been a bad time. We are living through the greatest improvement in human living standards in history. Extreme poverty has fallen below 10 per cent of the world’s population for the first time. It was 60 per cent when I was born. Global inequality has been plunging as Africa and Asia experience faster economic growth than Europe and North America; child mortality has fallen to record low levels; famine virtually went extinct; malaria, polio and heart disease are all in decline.
Little of this made the news, because good news is no news. But I’ve been watching it all closely. Ever since I wrote The Rational Optimist in 2010, I’ve been faced with “what about …” questions: what about the great recession, the euro crisis, Syria, Ukraine, Donald Trump? How can I possibly say that things are getting better, given all that? The answer is: because bad things happen while the world still gets better. Yet get better it does, and it has done so over the course of this decade at a rate that has astonished even starry-eyed me.
Perhaps one of the least fashionable predictions I made nine years ago was that “the ecological footprint of human activity is probably shrinking” and “we are getting more sustainable, not less, in the way we use the planet”. That is to say: our population and economy would grow, but we’d learn how to reduce what we take from the planet. And so it has proved. An MIT scientist, Andrew McAfee, recently documented this in a book called More from Less, showing how some nations are beginning to use less stuff: less metal, less water, less land. Not just in proportion to productivity: less stuff overall.
This does not quite fit with what the Extinction Rebellion lot are telling us. But the next time you hear Sir David Attenborough say: “Anyone who thinks that you can have infinite growth on a planet with finite resources is either a madman or an economist”, ask him this: “But what if economic growth means using less stuff, not more?” For example, a normal drink can today contains 13 grams of aluminium, much of it recycled. In 1959, it contained 85 grams. Substituting the former for the latter is a contribution to economic growth, but it reduces the resources consumed per drink.
As for Britain, our consumption of “stuff” probably peaked around the turn of the century — an achievement that has gone almost entirely unnoticed. But the evidence is there. In 2011 Chris Goodall, an investor in electric vehicles, published research showing that the UK was now using not just relatively less “stuff” every year, but absolutely less. Events have since vindicated his thesis. The quantity of all resources consumed per person in Britain (domestic extraction of biomass, metals, minerals and fossil fuels, plus imports minus exports) fell by a third between 2000 and 2017, from 12.5 tonnes to 8.5 tonnes. That’s a faster decline than the increase in the number of people, so it means fewer resources consumed overall.

On the eighth day of Christmas Thomas Alva Edison said: let there be light. Now, as we say say in the video, we know that Edison was not the only inventor of incandescent light, perhaps not even the inventor at all. But as with so many other things he brought the world, he was the first one to make it practicable, and perhaps more importantly; make it popular.It’s hard to fathom how monumental to humanity this day, 31st of December, 1879 is — the world literally changed forever with the flick of a switch. Our work behavior, or sleeping patterns, our leisure time, socializing, sex, media, industry, cooking, aesthetics … well more or less everything started to change on this day. In 2019 hardly anything we do is possible without it — especially not watching this video, which after all is brought to your eyes by one of many, many derivative innovations of the incandescent light bulb. In fact it’s 140 years later and we are still researching the depths of the change that incandescent light brought upon humanity.
Most of us take it for granted by now, artists celebrate it, entire industries depend on it, Luddites deplore it, environmental studies are showing that it might be harmful to other animals, neurologists are researching the effects of changed sleeping patterns on your brains, the production of energy we need to light our world has contributed to dramatic environmental changes on the entire planet, and the innovations coming from it just keep on pouring out of labs like Menlow Park every day. What do you think?
Happy New Year! May it be enlightening.

Anton Howes on the “improving mentality” of the British industrial revolution
In the latest Age of Invention newsletter, Anton Howes looks at some of the “bottom-up” educational initiatives that helped create and shape the industrial revolution:
I stumbled across a speech the other day, delivered by Dr Olinthus Gregory — the mathematics teacher at the Royal Military Academy at Woolwich — to the Deptford Mechanics’ Institution. The mechanics’ institutions, or institutes, were created by working men pooling their savings to pay for lectures, libraries, educational equipment, news-rooms, and book clubs. They spearheaded Britain’s bottom-up approach to adult education, with the classes held in the evenings after work. But they’re a story for another time.
Diagram of a Watt steam engine from Practical physics for secondary schools (1913).
Wikimedia Commons.What caught my eye was Gregory’s speech. Delivered in 1826, Britain’s industrial prowess was already obvious to many. The Industrial Revolution was already in full swing. Gregory paints the picture perfectly:
Agriculture, manufactures, commerce, navigation, the arts, and sciences, useful and ornamental, in a copious and inexhaustible variety, enhance the conveniences and embellishments of this otherwise happy spot. Cities thronged with inhabitants, warehouses filled with stores, markets and fairs with busy rustics; fields, villages, roads, seaports, all contributing to the riches and glory of our land.
But there was more to be done. After all, everything can always be improved (an attitude that I call the improving mentality):
Recollect farther, that every natural and every artificial advantage is susceptible of gradual progression, and trace the yearly elevation to higher perfection. New societies for improvement … new machines to advance our arts and facilitate labour; waste lands enclosed, roads improved, bridges erected, canals cut, tunnels excavated, marshes drained and cultivated, docks formed, ports enlarged: these and a thousand kindred operations which present themselves spontaneously to the mind’s eye, prove that we have not yet attained our zenith, and open an exquisite prospect of future stability and greatness.
Progress had been made, but there was always room for more.
As for the causes, Gregory had some interesting observations. Important, he said, was coal: “more valuable to us than the gold mines ever were to Spain, since without these the various metals could not be worked, and half our manufactories would be at a stand.”
But coal alone was not enough. There would be less output, of course, but he did not say that progress would have been stifled altogether (which is also more or less my own position). Also important was that inventors could persuade the government of the benefits of innovation, which is something I mentioned in my last email. As Gregory put it, Britain had “a government of whom the arts and sciences never crave audience in vain.”
And most important of all was Britain’s community of inventors and scientists, from the Boultons and Watts and Smeatons and Arkwrights and Bramahs, to the Donkins, Hornblowers, Trevithicks, Maudslays and Stephensons (only a few of whom are at all heard of today) …

“The near-homogeneity of Silicon Valley political beliefs has gone from wry punchline to national crisis in the United States”
Jason Morgan reviews Michael Rectenwald’s new book Google Archipelago: The Digital Gulag and the Simulation of Freedom:
The near-homogeneity of Silicon Valley political beliefs has gone from wry punchline to national crisis in the United States. The monoculture of virtue signaling and high- and heavy-handed woke corporate leftism at places like Google, Twitter, and Facebook was once a source of chagrin for those who found themselves shut out of various internet sites for deviating from the orthodoxies of the Palo Alto elites. After the 2016 presidential election, however, it became obvious that the digitalistas were doing a lot more than just making examples of a few handpicked “extremists.” From the shadow banning of non-leftist sites and views to full-complement political propagandizing, Bay Area leftists have been so aggressive in bending the national psyche to their will that there is talk in the papers and on the cable “news” channels of “existential threats to our democracy.”
It is tempting to see this as a function of political correctness. Americans, and others around the world, who have found themselves on the “wrong side of history” (as determined by the cultural elite in an endless cycle of epistemological door closing) have long been shut out of conversations, their views deemed beyond the pale of acceptable discourse in enlightened modern societies. Google, Facebook, Twitter — are these corporations, and their uber-woke CEOs, just cranking the PC up to eleven and imposing their schoolmarmish proclivities on the billions of people who want to scrawl messages on their electronic chalkboards?
Not so, says reformed leftist — and current PC target — Michael Rectenwald. The truth of Stanford and Harvard alumni’s death grip on global discourse is much more complicated than just PC run amok. It is not that the Silicon Valley giants are agents of mass surveillance and censorship (although mass surveillance and censorship are precisely the business they’re in). It’s that the very system they have designed is, structurally, the same as the systems of oppression that blanketed and smothered free expression in so much of the world during the previous century. In his latest book, Google Archipelago, Rectenwald outlines how this system works, why leftism is synonymous with oppression, and how the Google Archipelago’s regime of “simulated reality” “must be countered, not only with real knowledge, but with a metaphysics of truth.”
Google Archipelago is divided into eight chapters and is rooted in both Rectenwald’s encyclopedic knowledge of the history of science and corporate control of culture, as well as in his own experiences. Before retiring, Rectenwald had been a professor at New York University, where he was thoroughly entrenched in the PC episteme that squelches real thought at universities across North America and beyond. Gradually, Rectenwald began to realize that PC was not a philosophy, but the enemy of open inquiry. For this reason, and because Rectenwald is an expert in the so-called digital humanities and the long history of scientific (and pseudo-scientific) thinking that feeds into it, Google Archipelago is not just a dry monograph about a social issue. By turns memoir, Kafkaesque dream sequence, trenchant rebuke of leftist censorship, and intellectual history of woke corporate political correctness, Google Archipelago is a welcoming window into a mind working happily in overdrive.

The United States was losing the space race. A number of unfortunate missteps and mistakes had hindered their progress. But the United States had also structured its space program entirely differently from the USSR. Instead of being helmed by the military, the National Aeronautics & Space Administration was created by Eisenhower with an emphasis on exploration and research. And in the end, the later but more advanced satellites will collect the data required a dream firmly placed in the American consciousness by JFK. A dream to place a man on the moon.

Bryan Donkin, 19th century inventor, amateur public relations whiz and independent lobbyist
In the latest installment of Anton Howes’ Age of Invention newsletter, he recounts the story of Bryan Donkin and his efforts to save innovators from excessive government interference:
One of the major arguments of the book I’m writing is that inventors’ talent for public relations and lobbying was one of the main reasons that Britain — rather unexpectedly — was the place that experienced an unprecedented acceleration of innovation.
The greatest of these lobbyist-inventors has to be Bryan Donkin, a nineteenth-century mechanical engineer. As an inventor, Donkin improved threshing machines, dredging machinery, and a variety of other tools. He invented the steel pen, dabbled in chemistry, as well as phrenology, and was one of the key people responsible for mechanising the production of paper. He became best known for improving and commercialising tin cans for food. Mechanised paper-making and canned food, having both been invented in France, were perfected in Britain by Donkin. He was the archetypal tinkerer.
But it’s as a lobbyist that I think Donkin was truly exceptional. His experience has important lessons for all would-be supporters of invention today.
In April 1817, Donkin read in his newspaper that there had been a disaster in Norwich: the boiler aboard the steamboat Telegraph had exploded. Of the boat’s twenty-two passengers, eight had died immediately in the blast, and another six had eventually succumbed to their wounds. It was a shocking tragedy. And for Donkin, doubly so: in addition to the human death toll, the explosion threatened to kill off one of the era’s newest and most exciting inventions.
Although some of the first trials of steamboats had taken place in the 1780s, it wasn’t until the turn of the century that they began to be practical. By 1817, the first commercially successful steamboat service in Britain, Henry Bell’s Comet, had been chugging its way up the River Clyde between Glasgow and Greenock for only five years. And Londoners like Donkin had only just seen their first steamboat, Margery, when she puffed her way into the Thames in 1815 (the following year, after becoming the first steamboat to cross the Channel, she reinvented herself in Paris as Elise). Thus, by the time of Telegraph‘s explosion, the passenger steamboat had only just been born. There was a very real risk that it would be banned.
Fortunately, however, the steamboat had Donkin in its corner. His immediate reaction upon reading about the explosion was to gather some of his engineer friends — Timothy Bramah and John Collinge — and set off for Norwich to view the explosion site for themselves. As the first expert engineers on the scene, they then took control of the narrative about the explosion. Donkin and his friends went straight to Norwich’s MP to ask him to set up a parliamentary select committee to look into the disaster. And while they waited for the politicians to be assembled for the committee, they held a series of public meetings about the disaster at the Crown & Anchor Tavern — a favourite haunt of London’s engineers. There, they had a chance to rally the rest of the profession and get their story straight about what must have caused the explosion.
