Awesome find, I personally have never heard of this version. I did some research and found this. It's more detailed info on this bird. Thanks for
sharing.
The Have Blue aircraft had the same general shape as that which would later become familiar with the F-117A, except that the twin rudders were located
forward of the exhaust ejectors and were angled inward rather than outward. The inward cant was about 30 degrees.
[Three view drawing of Have Blue. (Lockheed Martin Skunk Works)]The leading edge of the semi-delta wing was swept back at 72.5 degrees. The wing
featured two inboard trailing edge elevons for pitch and roll control. Four spoilers (two on top of the wing and two on the bottom) were mounted just
forward of the elevons. There were no flaps or speed brakes. The wing trailing edge was less deeply notched than that of the F-117A. A single cockpit
with an ejector seat was provided. The Have Blue aircraft employed V-type windshields (similar to those of the F-102/F-106). No weapons bay nor any
sort of tactical equipment at all was fitted.
The Have Blue aircraft were equipped with fly-by-wire (FBW) flight controls which were adapted from the F-16 system. However, the system had to be
modified to handle an aircraft that was unstable about all three axis (the F-16 is unstable only about the pitch axis). The problem of designing a
stealthy system for airspeed measurement had not yet been solved, and XST-1 was equipped with a conventional pitot boom until March 1978. The boom was
removed after it's 32nd flight. XST-2 never had the conventional pitot boom.

aircraft. Lockheed workers assembled the two Have Blue aircraft in Burbank in Building 82, one of their big assembly hangers that was the size of
three football fields. Reports that state the Have Blue were built in Lockheed's Plant 10 facility housed at the USAF Plant 42 in Palmdale, California
are false. According the book "Skunk Works": "The Skunk Works workers were all specialist in specific sections of the airplane: fuselage, tail, wings,
control surfaces, and power plant. Each section was built separately then brought together. About 80 people were on this project, and because the
Skunk Works was in a rush the airplane was stood on it's tail and assembled vertically. That way, the assemblers could work on the flat, plated
structural frame, front and back, asses to elbows."
Neither aircraft ever received an official DOD designation, or did they get a USAF serial number. However, Lockheed did give the aircraft its own
manufacturer's serial numbers-1001 and 1002. These numbers are commonly used (Lockheed had a YF-12 that was #1001 as did Northrop have a B-2). These
numbers did not mean Plant 10, aircraft numbers 1 and 2.
[Two photos of Have Blue. (Lockheed Martin Skunk Works)]The first example (1001) was finished in November of 1977. Engine run tests were done on
November 4, 1977. To hide the plane, 1001 was parked between two semitrailers and a camouflage net was draped over them. The tests were done at night,
after Burbank airport had closed. The only attention the test attracted was a complaint from a local resident about noise. In order to keep the
project away from prying eyes, the Have Blue prototype was shipped out to the Groom Lake Test Facility in Nevada in high secrecy on the morning of
November 16, 1977 for the test flights. Groom Lake is located in a particularly remote area of the Nellis test range complex, and is a good location
for the testing of secret aircraft. A camouflage paint scheme was applied to make it hard for unwanted observers at Groom Lake to determine the
aircraft's shape.
Seventy-two hours before the first test flight, the airplane began to seriously overheat near the tail during engine test runs. The engine was
removed, and Bob Murphy and a helper decided to improvise by building a heat shield. They noticed a six-foot steel shop cabinet. "Steel is steel,"
Murphy said to his assistant. "We'll send Ben Rich the bill for a new cabinet." They began cutting up the cabinet to make the heat shield panels
between Have Blue's surface and its engine. It worked perfectly.
The first flight of the Have Blue took place shortly before 7am on December 1, 1977, with veteran Lockheed test pilot William M. "Bill" Park being at
the controls. (Park was so highly regarded at Skunk Works that Ben Rich obtained a special exemption from the air force so he could be chief test
pilot. As a note: Park was not a test pilot school graduate, nor did he have an advanced engineering degree.) As the plane took to the sky, Kelly
Johnson slapped Ben rich on the back and said, "Well, Ben, you got your first airplane." At an early stage, Bill Park was assisted in the flight test
program by Lt. Col. Norman Kenneth "Ken" Dyson of the USAF.
