Have Blue and the Birth of Operational Stealth

Lockheed's Skunk Works flew Have Blue demonstrators in the late 1970s to prove a rude idea: faceted shapes could swallow radar returns well enough to matter. Senior Trend turned the lesson into the F-117 Nighthawk. The Pentagon acknowledged the jet in 1988 and showed it in 1990. Black aviation became a museum fact.

Skunk Works to Senior Trend

Lockheed Martin's F-117 history feature and Air & Space Forces Magazine's stealth fielding history keep the timeline public: https://www.lockheedmartin.com/en-us/news/features/history/f-117.html. Ben Rich's era, Hopeless Diamond geometry folklore in aviation press, and production realities sit in that lane. Area 51's documented test role is a neighbor title—not a license to paste every triangle sighting onto Have Blue.

Facets Before Curves

Have Blue's faceted proof preceded Tacit Blue's curved-stealth lessons. Both are documentary. Triangle-UFO conflation is optional folklore, not required by Skunk Works timelines.

Settled Black Jet Versus Aurora Fanfic

Settled: Have Blue demonstrators; F-117 operational path; 1988–1990 public reveal. Not required: equating every black triangle rumor with this program. Keep the facets and the acknowledgment dates.

Source Discipline for This Page

The strongest claims on Have Blue and the Birth of Operational Stealth are tethered to dated primary URLs in the sources list—NRO/CIA/NASA/DOE histories, museum fact sheets, or peer-reviewed surveys. Secondary aviation magazines can open the door; they should not outrun the paperwork. Fringe fleet myths stay labeled and downstream.

Comparative Archive reading stays useful only when black-program titles stay distinct: link neighbors for method or chronology, not because every cancelled aerospace project is secretly still flying.

Comparative Archive reading helps only when neighboring titles stay distinct: link for method, chronology, or institutional pattern, not because every cancelled program or scandal is secretly the same story. Local facts for Have Blue and the Birth of Operational Stealth still have to carry this page.

If a claim cannot be pointed at a named date, named institution, or named primary URL in sources[], park it as contested interpretation rather than settled Archive fact.
