North American Rockwell registered a near identical patent in 1968, related to their FX design.

This is for the FX that resulted in F-15? I'd be surprised if they were considering reducing RCS that far back.

You may have heard of this beast:

The losing competitor:

Both had features ahead of their time that appear right at home on today's stealth aircraft.  I am QUITE certain they were working on reducing RCS that far back.

Actually, there is a patent in the early 70's for a plasma field in the inlet of the F-15 to hide the fan face from radar. Stealth actually was being considered back then, as stealth investigations really accelerated in the late 50's and early 60's leading up to HAVE BLUE in the mid 70's.

From the articles I've read thus far, the Block III won't itself bring a new engine; they'll likely just bring in EPEs, EDEs or something even newer in the future (I doubt it'll be that long of a wait though).

Hi! My latest poor speculation for IL-54 design evolution.

A Look Inside Space Fence’s 7,000 Square-Foot Radar Array

May 02, 2017

Currently under construction on the remote island of Kwajalein, Space Fence is a radar system that will help the U.S. Air Force better track space junk. General Dynamics SATCOM Technologies is partnered with Lockheed Martin to build the ground structures for Space Fence, which includes the 7,000 square-foot radar receive array structure.

In an article in Stars and Stripes, Wyatt Olson reported on his experience walking inside the Space Fence radar array structure with Bruce Schafhauser, Lockheed Martin’s program director.

    The site is composed of two pressurized radar chambers, one for transmitting into space and the other for receiving those radio frequencies. Roofs covering each chamber are made of thick, electronically transparent Kevlar.

    Passing through air locks into the radar chambers is an ear-popping experience. At the chambers’ ground level is a crisscross of a million pounds of anchoring steel.

    “What you’re looking at is a steel structure that’s very sturdy to not only maintain alignment of the radar array face, which is at the very top of this, but also because we have seismic requirements that we’re dealing with here,” Schafhauser said during the tour. “That accounts for the size of it all.”

    Wide aluminum columns carry coolant, and 50,000 tons of concrete make up the thick foundation and walls.

The General Dynamics-built radar array is designed to withstand earthquakes, hurricane force winds, and extremes in temperature. Once operational, the 700,000 pound steel structure will be sensitive enough to locate and track objects the size of a softball hundreds of miles above the Earth.

About Space Fence

Space Fence is an advanced ground-based radar system that will enable the Air Force to better monitor over 200,000 objects orbiting the Earth. Space Fence will use a highly sensitive S-band radar to identify and track these objects, which will help prevent satellites and the International Space Station from colliding with debris.

I was part of the media team which were invited to the T-625 event on the Monday afternoon so here are my photos,

A very smart application for civil operations.  I remain unconvinced that it has a good military application, although naval forces have much better understanding of working in proximity to air vehicles that want to kill you. 
I attended the rpess brief ;last Tuesday and we went to Clean SKies booth to see it being unveiled my photos here

and heres Airbus Helicotpers official video


Festung Norvegen holds out about as long as the fuel and aircraft parts do. After that it's goodbye. If Japan couldn't last into 1946 and mainland Germany couldn't last into the latter half of 1945, I don't see much chance of transferring enough material or industry into Norway to hold out for very long.

If you can magically transport all of Germany's industry and resources there, perhaps another six months. Perhaps. Among other things, the Soviets will probably come up through Finland and push the Germans into the sea, leading to the Sovietization of Scandinavia and a very different post-war world.
