They were military barbettes for naval guns.   As such, they were more lightly armoured than naval barbettes (relying on concrete and earth berms for most of their defence).   If they were to be mounted onto a land vehicle, they'd need serious up-armouring even beyond that of the naval barbettes.

On a side note:
Dieter Grau, one of the original German scientists who came to America with Wernher von Braun at the end of World War II and developed the space program that put men on the moon, passed away this week in Huntsville. He was 101. :(

And in Germany, the last school in Germany to be named after Werner von Braun, changed to be named after Johannes Kepler.
So called "Helicopter parents" didn't want to send their children to a "Nazi-School" anymore.  ::)

Scroll halfway down the memorial page for the B&W and color versions of the illustration; listed as "speculative". The art, by Australian Mark Kopp (brother to Dr. Carlo Kopp) does not appear to have any connection to Northrop.

Sorry folks, I got mixed up about the KC-46 prototype designations and their planned first flights.
First flight test window for the 767-2C EMD-1 is set for December 27th or 28th; KC-46 EMD-2 first flight planned for April 2015.
Quote
[...]The first flight test window for the 767-2C which includes wiring, plumbing, doors and floors is set for Dec. 27 with a backup one day later, USAF Brig. Gen. Duke Richardson, program executive officer for tankers, said in an interview with Aviation Week.
This first flight for engineering and manufacturing development (EMD)-1 aircraft is critical toward the next first flight milestone. EMD-2, the first fully configured KC-46 aerial refueler, is slated to take to the skies in April.[...]

Considering the style of the artwork and the company's practice at that time of incorporating the design number into the paintings, I think it is a safe bet to assume that this image depicts the Northrop N363. This number is perfectly coherent with the Northrop design number chronology, placing it in 1983.

However, the would-be F-19 demonstrator, if ever built, would have been prior to that, presumably around 1981, which has led some to believe that it may have been related to another Northrop design, the smaller scale THAP demonstrator, rather than the full-scale operational CSIRS in the picture. But then a whole lot of theories and conjectures have been associated to this whole matter, so that in the end it's hard to know what to think.

One thing I know for a fact:
>> The F-19, whether built or merely planned, could NOT be the F-117A for the simple reason that the latter was always meant as a pure low altitude ground attack platform, not a fighter. The unofficial secret F-"century" series types could be anything: attack, fighter, recce... but the regular F- series was for fighters/pursuits/interceptors or whatever.

One thing I have seen (even saved, but then lost in a computer crash):
>> In the early 2000s, the webpage of an industry subcontractor (whose name I forgot) listed the projects they had been involved in, and for each of them, provided a small recap of the aircraft's performances. Surprisingly, they listed the "F-19" as a program they'd worked on and provided a whole set of specs that was clearly for a fighter and had nothing to do with the F-117A. Now why would they do that? I could not say.

One thing I very much believe:
>> With stealth being completely new and unproven, the USAF likely didn't put all their eggs in one basket and must have considered several configurations for testing and possibly several companies each working on a different type of design. Perhaps there were only Have Blue and Tacit Blue, perhaps there could have been a couple more test planes in-between that are still unheard of. But of course if there ever were such planes, they probably were failures and/or crashed, otherwise we'd have heard about them and they'd be in a museum by now. They might also have been company-financed prototypes, hence the lack of obligation by the DoD to go public about them and the lack of desire from the companies to brag about failed projects.

After going through the report in a little more detail, it appears that these were studied by McDonnell Douglas under contract from NASA:

Quote
In order to not restrict concept selection and creative thinking, NASA only specified the concepts to be of helicopter-like disk loading and capable of forward flight in the 450-kt range.

The report states clearly that this study (notably the rotor-wing configuration) rely heavily on research done by Hughes 25 years before:

Quote
Due to the amount of initial concept exploration in the mid-60s, including whirlstand, wind tunnel, dynamic model conversion, and transonic tests, much is known about this configuration. The XH-17 and XV-9A technology demonstrators incorporated reaction drive rotors in their designs. (...) Data from the 1960s wind-tunnel tests, completed by Hughes Tool Company, determined the lift and drag characteristics of various centerbody shapes.

Aerospace / Re: UK Hueys

There are also some RAF Hueys in blue for SAR / support, normally over in Cyprus.
The Army Air Corps has some in green / grey camo for Belize, maybe Brunei too.   

Both types come over to the UK too, for maintenance / refits / training.

The one you saw was in a glossy black, with yellow, assigned to the Defence Helicopter Flying School.  Civilian I think, but they use mil-registered helos.
