Times are changing . . .
— MQ-4C Triton — |
So, this is old news, and why dredge it up? Well, there were a couple of happenings this week that might offer interesting alternatives to the F-35. The US Navy is proceeding with its program to acquire RPV (remotely piloted vehicles)-drone (autonomous, self-controlled) capabilities for both surveillance and interception. These drone-RPV's are not the Predators that have the Taliban so upset, the Predator is like a WW1 Sopwith Camel, and these are like WW2 F-4U Corsairs, faster, deadlier, tougher, with all-weather de-icing, and capable of the "controlled crash" of carrier landings.
The first happening was an "oops!" — the USN reported the crash of one of their "older" prototype BAMS-D vehicles. They are unarmed, improved versions of the Northrop Global Hawk, with BAMS as their mission: Broad Area Maritime Surveillance, but BAMS-D is an interim model; it's full-strength BAMS that the USN is developing for the decades ahead. What's a BAMS? A heavy-duty Global Hawk, called the MQ-4C Triton.
— X-47B UCLASS hunter-killer — |
— Boeing's UCLASS design — |
Once outside U.S. airspace, BAMS can cruise at altitudes well above most air lanes used by passenger jets and other manned aircraft. Unlike Global Hawk, however, BAMS will be able to descend to lower altitudes if necessary to more closely examine items of interest picked up by its ISR radar or daylight and infrared cameras.
An RPV-drone that will be flying in commercial airspace, if its controllers want. The Navy is also putting a two-way radio on BAMS so its crew can talk to air traffic controllers the way manned aircraft pilots do, and it's equipping the drone with standard safe separation and navigation and surveillance technologies manned aircraft use -- TCAS (Traffic Collision Avoidance System) and ADS-B (Automatic Dependent Surveillance Broadcast).
The second happening was the approval of landing software for UCLASS: Unmanned Carrier-launched Airborne Surveillance and Strike. The USN is very serious about RPV-drones as offensive weapons too. It's about saving money and lives. The USN is trying to reduce the sheer number of sailors required to fight a ship by automating systems wherever possible, as you may have noticed with the Zumwalt, the proposed new USN littoral frigate. Saves payroll, training costs, but also reduced human environmental concerns promotes survivability in combat.
A 7-g loading is about the limit for humans; it's debilitating, and even with training and g-suits, pilots can't take a lot and as well, the change from plus-g to minus-g loading adds to the wear-and-tear as the human circulatory system rebels. The USN is working on offensive, "killer" RPV drones that will do + 12g -12g as fast as the RPV pilot can tell it to do so, and keep doing it until it runs out of fuel. Dog-fight hunter-killer, indeed.
Boeing and Northrop are building prototypes. The Northrop X-47B and the as-yet un-named Boeing design are the first generation of really high-performance (high sub-sonic) offensive RPV's. Northrop's software for automated carrier landings has been approved. Projected timeline is 2018, for the first carrier landings of the X-47B.
Canada has to make a choice, and make it soon, as to replacing our F-18's. My opinion is that Canada should walk away from the F-35, and buy as many Super Hornets as we need, and improved JDAM's for them. With the money thus saved, Canada should get involved in the USN RPV-drone program.
Looking into the future, sometimes greedy nations get stupid over sovereignty, so maybe the acquisition of an offensive RPV-drone might be a good way to convince the other Arctic nations and those countries that wish to be intrusive, that we really do care about our turf. And if it has to go active, well +/- 12 g's and 30mm cannon or whatever missile it launches will probably fix the problem.
Canadian involvement in the RPV-drone programs can only help our computer design industry stay with the future — this appears to be a growth industry, unlike building manned fighter aircraft. It's all about the development of Artificial Intelligence, a Super Siri, a happy HAL, a C3PO or an R2D2: it's coming, and it might be a good idea for Canada to have a part in how it comes about. But Stevie wants the F-35.

Pushing the envelope . . .

PIXAR'S CARS 2 is an incredible technical achievement. According to CNET's Daniel Terdiman, it's a whole new animation universe. 80 to 90 hours rendering time for a frame that lasts 1/30 of a second when projected — wow!
One of the keys to Pixar's ability to do what it does is the giant, powerful render farm located in its main headquarters building here. This is serious computing power, and on "Cars 2," it required an average of 11.5 hours to render each frame.
But some sequences were especially complex, particularly those involving ray tracing--which involves simulating light hitting surfaces, essentially "trying to simulate photons." And as a result, a huge amount of computing power was needed to process frames that took as much as 80 or 90 hours to render, Shah said. And that meant that the studio "bulked up our render farm."
He said that Pixar had to triple its size, and today, the render farm features 12,500 cores on Dell render blades*. As well, the file servers, network backbone, and every other piece of the computing puzzle was boosted in order to handle the making of "Cars 2."
* Non-IT people may be unaware that a "blade" is an IT term for a simple motherboard with RAM, that has no peripheral cards or hard drives, etc., that is part of a computational system.
