Burbank origins 1928 (Lockheed)
Lockheed Airport 1940 (USAAC)

Model designations for some Lockheeds were sometimes preceded by an L (as L-12 for Electra 12) or, following World War 2, by a V (as V-1 for Vega 1), as devised by Lockheed. During Detroit Aircraft ownership in 1929-31, certain models appeared with DL-number designations, and are listed thusly. Groupings are by familiar name before the model number for visual simplicity, although they are often seen the other way around in publications.

This aircraft, indeed, has Bristol Orpheus Change Unit engines Mk 810D, but she was equipped with only two engines, not four as you describe. Other interesting facts is that it only has single-wheel main gears, as opposed to the production model that had double-wheel mains.

  Testors F-19

F-19 - No such animal. It is officially undocumented, but generally assumed that the F-19 designation was skipped in 1982 in order to honor the Northrop F-20 (qv) with an even "next-generation" number.

Striving to keep pace with technology, Testors hit the market with an F-19 kit based on eyewitness reports from "usually reliable sources," research, gut level guesswork, and patterned it after the smooth-surfaced Lockheed SR-71. By May 1986 their kit was on hobby shop shelves and nearly 700,000 were sold in 18 months. However, somebody had pulled a plug in the Pentagon.

    Stealth technology at the time was one of our military's worst-kept secrets, and it was assumed that F-19 had been reserved for that department. There was so much speculation that the USAF, with uncommon humor, even roped off a vacant plot at the 1988 Edwards AFB Air Show with a sign identifying the "F-19 Flying Frisbee." But when the much-heralded stealth fighter was designated F-117A and was anything but smooth, the F-19 idea lost most of its lustre, and folks generally accepted that the designation had been purposely skipped when F-20 showed up.

    Yet, much like with those little green men they scraped off the Roswell landscape, folklore and wishful thinking took hold, and there came many reports from "usually reliable sources" who saw the real Testors F-19 flying around in remote desert regions usually off-limits to reliable sources. (Because of the popularity of the designation, the USAF Museum's Internet page lists a "Lockheed F-19 CSIRS," but its link connects the F-117A.) (— K O Eckland)

  Lockheed Martin-Boeing F-22 [USAF]

F-22 Raptor (Lockheed Martin-Boeing-P&W) 1997 = 1pCmwM rg. In 1981 USAF developed a requirement for a twin-tail, variable delta-wing Advanced Tactical Fighter (ATF) to take advantage of new technologies in fighter design, including composite materials, lightweight alloys, advanced flight control systems, higher power propulsion systems, and stealth technology. It was believed these technologies would make aircraft like the F-15 and F-16 obsolete by the early 21st century. In 1985 the Air Force sent requests for proposals to a number of aircraft manufacturers and selected two industry teams, one led by Lockheed and the other by Northrop, to build the prototypes. Each team built two prototypes, one with GE YF120 and one with P&W YF119 engines. Lockheed's aircraft was designated YF-22, and the Northrop Aircraft YF-23. In 1990, the USAF pegged the price of F-22 at $100 million each, but advisors said it was closer to $130 million. After extensive flight tests the tea, then Lockheed Martin, Boeing, and General Dynamics, team won the airframe competition and P&W got the engine contract. In 1997 the YF-22 prototype that had been equipped with GE engines went to the Air Force Museum, where it was refurbished and put on display.
