Rohr, Inc., a wholly owned unit of United Technologies Corporation, an aerospace manufacturing company based in Chula Vista, California, south of San Diego.
 Rohr, Inc. operates as a subsidiary and largest business unit of UTC Aerospace Systems.
 It was founded in 1940 as Rohr Aircraft.
United Technologies Corporation (UTC) is an American multinational conglomerate headquartered in Farmington, Connecticut.
 It researches, develops, and manufactures products in numerous areas, including aircraft engines, aerospace systems, HVAC, elevators and escalators, fire and security, building systems, and industrial products, among others.
 UTC is also a large military contractor, getting about 10% of its revenue from the U.S. government.
 Gregory J. Hayes is the CEO and chairman.
A black project is in the vernacular of the United States and United Kingdom militaries, a highly classified military or defense project, unacknowledged publicly by the government, military personnel, or defense contractors.
 Examples of U.S. military aircraft developed as black projects include the F-117 Nighthawk stealth attack aircraft and the B-2 Spirit stealth bomber, both of which were highly classified and denied as existing until ready to be announced to the public.
 In the United States the formal term is "Special access program (SAP)".
Lockheed "Have Blue" was the code name for Lockheed's demonstrator (i.e., "proof of concept") that preceded the F-117 Nighthawk production stealth aircraft.
 "Have Blue" was designed by Lockheed's Skunk Works division, and tested at Groom Lake, Nevada.
 The "Have Blue" was the first fixed-wing aircraft whose external shape was defined by radar engineering rather than by aerospace engineering.
 The aircraft's plate-like, faceted shape was designed to deflect electromagnetic waves in directions other than that of the originating radar emitter, greatly reducing its radar cross-section.
 Two flyable vehicles were constructed, but both crashed during the flight-test program.
UTC Aerospace Systems (UTAS) was formed by United Technologies Corporation in August 2012 by combining two companies: Goodrich Corporation and Hamilton Sundstrand.
 UTC Aerospace Systems is headquartered in Charlotte, North Carolina.
ACES II is an ejection seat system manufactured by the United Technologies Aerospace Systems (UTAS) division of the United Technologies Corporation (UTC).
 ACES is an acronym for Advanced Concept Ejection Seat.
 It is used in Fairchild Republic A-10 Thunderbolt II, McDonnell Douglas F-15 Eagle, General Dynamics F-16 Fighting Falcon, Lockheed Martin F-22 Raptor, Lockheed F-117 Nighthawk, Rockwell B-1 Lancer, WB-57, and Northrop Grumman B-2 Spirit aircraft.
 Over 10,000 ACES II seats have been produced with over 5,000 actively flying throughout the world as of 2013.
 It is known throughout the industry as the lowest life cycle cost third generation seat due to the USAF owning the rights to the seat, facilitating competitive replacement part procurement.
 In addition, the buying power of 5,000 in-service seats and previous service life extension programs have further driven down support costs.
Hamilton Sundstrand was an American globally active corporation that manufactured and supported aerospace and industrial products for worldwide markets.
 A subsidiary of United Technologies Corporation, it was headquartered in Windsor Locks, Connecticut.
 The company was formed from the merger of Hamilton Standard and Sundstrand Corporation in 1999.
 In 2012, Hamilton Sundstrand was merged with Goodrich Corporation to form UTC Aerospace Systems.
The Lockheed F-117 Nighthawk is a single-seat, twin-engine stealth attack aircraft that was developed by Lockheed's secretive Skunk Works division and operated by the United States Air Force (USAF).
 The F-117 was based on the "Have Blue" technology demonstrator.
Skunk Works is an official pseudonym for Lockheed Martin's Advanced Development Programs (ADP), formerly called Lockheed Advanced Development Projects.
 It is responsible for a number of famous aircraft designs, including the U-2, the Lockheed SR-71 Blackbird, the Lockheed F-117 Nighthawk, Lockheed Martin F-22 Raptor, and the Lockheed Martin F-35 Lightning II, which will be used in the air forces of several countries.
 Its name was taken from the moonshine factory in the comic strip "Li'l Abner".
 The designation "skunk works" or "skunkworks" is widely used in business, engineering, and technical fields to describe a group within an organization given a high degree of autonomy and unhampered by bureaucracy, with the task of working on advanced or secret projects.
Henry Combs was a structural engineer at Clarence Johnson's famed Skunk Works group of Lockheed Corporation.
 He was Deputy Project Manager on the Lockheed U-2 program, Head Structural Engineer on the SR-71 Blackbird, and later, Technical Director of the Skunk Works.
 While he is most known for his integral work on the U-2, the SR-71 and the F-117 Nighthawk, he also worked on the F-104, Lockheed Constellation, C-130 Hercules, XP-58 Chain Lightning, and Lockheed JetStar.
