17 April 1956: Lockheed Aircraft Corporation rolled out the very first production F-104A Starfighter, 55-2956, at Air Force Plant 42, Palmdale, California. This airplane, one of the original seventeen pre-production YF-104As, incorporated many improvements over the XF-104 prototype, the most visible being a longer fuselage.

Once the configuration was finalized, 55-2956 was the first YF-104A converted to the F-104A production standard. In this photograph, the F-104’s secret engine intakes are covered by false fairings.

The Lockheed F-104A Starfighter was a single-place, single-engine supersonic interceptor. It was designed by a team lead by the legendary Clarence L. “Kelly” Johnson. The F-104A was 54 feet, 8 inches (16.662 meters) long with a wingspan of 21 feet, 9 inches (6.629 meters) and overall height of 13 feet, 5 inches (4.089 meters). It had an empty weight of 13,184 pounds (5,980.2 kilograms), combat weight of 17,988 pounds (8,159.2 kilograms), gross weight of 22,614 pounds (10,257.5 kilograms) and a maximum takeoff weight of 25,840 pounds (11,720.8 kilograms). Internal fuel capacity was 897 gallons (3,395.5 liters).

The F-104A was powered by a single General Electric J79-GE-3A engine, a single-spool axial-flow afterburning turbojet, which used a 17-stage compressor and 3-stage turbine. The J79-GE-3A is rated at 9,600 pounds of thrust (42.70 kilonewtons), and 15,000 pounds (66.72 kilonewtons) with afterburner. The engine is 17 feet, 3.5 inches (5.271 meters) long, 3 feet, 2.3 inches (0.973 meters) in diameter, and weighs 3,325 pounds (1,508 kilograms).

The F-104A had a maximum speed of 1,037 miles per hour (1,669 kilometers per hour) at 50,000 feet (15,240 meters). Its stall speed was 198 miles per hour (319 kilometers per hour). The Starfighter’s initial rate of climb was 60,395 feet per minute (306.8 meters per second) and its service ceiling was 64,795 feet (19,750 meters).

Armament was one General Electric M61 Vulcan six-barreled revolving cannon with 725 rounds of 20 mm ammunition. An AIM-9B Sidewinder heat-seeking air-to-air missile could be carried on each wing tip, or a jettisonable fuel tank with a capacity of 141.5 gallons (535.6 liters).

Lockheed built 153 of the F-104A Starfighter initial production version. A total of 2,578 F-104s of all variants were produced by Lockheed and its licensees, Canadair, Fiat, Fokker, MBB, Messerschmitt,  Mitsubishi and SABCA. By 1969, the F-104A had been retired from service. The last Starfighter, an Aeritalia-built F-104S ASA/M of the  Aeronautica Militare Italiana, was retired in October 2004.

This Starfighter, 55-2956, was converted to a JF-104A with specialized instrumentation. It was transferred to the U.S. Navy to test AIM-9 Sidewinder missiles at Naval Ordnance Test Station (NOTS) China Lake, approximately 55 miles (88 kilometers) north-northeast of Edwards Air Force Base in the high desert of Southern California. 55-2956 was damaged beyond repair when it lost power on takeoff and ran off the runway at Armitage Field, 15 June 1959.

23 December 1974: The first of four prototype Rockwell B-1A Lancer Mach 2.2 strategic bombers, serial number 74-0158, made its first flight from Air Force Plant 42, Palmdale, California. The aircraft commander was company test pilot Charles C. Bock, Jr. (Colonel, U.S. Air Force, retired) with pilot Colonel Emil Sturmthal, U.S. Air Force, and flight test engineer Richard Abrams. After basic flight evaluation, the B-1A landed at Edwards Air Force Base, about 22 miles (35 kilometers) to the northeast of Palmdale.

The Rockwell International B-1A Lancer was designed to operate with a flight crew of four. It was 150 feet, 2.5 inches (45.784 meters) long. With the wings fully swept, the span was 78 feet, 2.5 inches (23.838 meters), and extended, 136 feet, 8.5 inches (41.669 meters). The tip of the vertical fin was 33 feet, 7.25 inches (10.243 meters) high. Loaded weight for the B-1A was 389,000 pounds (176,447 kilograms).

The Lancer was powered by four General Electric F101-GE-100 afterburning turbofan engines. This is an axial-flow engine with a 2-stage fan section, 9-stage compressor and 3-stage turbine (1 high- and 2 low-pressure stages). It is rated at 17,000 pounds of thrust (75.62 kilonewtons), and 30,000 pounds (133.45 kilonewtons) with afterburner. The F101-GE-100 is 15 feet, 0.7 inches (4.590 meters) long, 4 feet, 7.2 inches (1.402 meters) in diameter, and weighs 4,460 pounds (2,023 kilograms).

The bomber’s maximum speed was 1,390 miles per hour (2,237 kilometers per hour) and its service ceiling was 60,000 feet (18,288 meters). Unrefueled range was 6,100 miles (9,817 kilometers).

The B-1A was designed to carry 75,000 pounds (34,019 kilograms) of bombs in an internal bomb bay.

Each of the four prototypes served its own role during testing. 74-0158 was the flight evaluation aircraft.

By the time that the B-1A program was cancelled, 74-0158 had made 79 flights totaling 405.3 hours. It was dismantled and used for weapons training at Lowry Air Force Base, Colorado.

16 November 1970: At the Lockheed California Company Plant 10, just north of Palmdale in the high desert of Southern California, test pilot Henry Baird (“Hank”) Dees, co-pilot Ralph C. Cokely (formerly a Boeing 747 test pilot), with flight test engineers Glenn E. Fisher and Rod Bray, took the new prototype Lockheed L-1011-1 TriStar, N1011, on its first flight.

During the 2½-hour test flight, the airliner reached 250 knots (288 miles per hour, 463 kilometers per hour) and 20,000 feet (6,096 meters).

The Lockheed L-1011 TriStar is a three-engine wide body airliner designed to carry up to 400 passengers on medium or long distance routes. It is operated by a flight crew of three. The prototype, the L-1011-1 and L-1011-200 production aircraft were 177 feet, 8½ inches (54.166 meters) long with a wingspan of 155 feet, 4 inches (47.346 meters). The longer range, higher gross weight L-1011-500 variant was 164 feet, 2½ inches (50.051 meters) long with a wingspan of 164 feet, 4 inches (50.089 meters). All TriStars have an overall height of 55 feet, 4 inches (16.866 meters). The interior cabin width is 18 feet, 11 inches (5.766 meters). Empty weight ranges from 241,700 pounds (109,633 kilograms) to 245,400 pounds (111,312 kilograms), while the maximum takeoff weight varies from 430,000 pounds (195,045 kilograms) to 510,000 pounds (231,332 kilograms).

The L-1011-1 aircraft were powered by three Rolls Royce RB.211-22B-02 high bypass turbofan engines, producing 42,000 pounds of thrust (186.825 kilonewtons). The -200 and -500 variants used the more powerful RB.211-524B4 which produces 53,000 pounds (235.756 kilonewtons). The RB.211-22 is a “triple-spool” axial-flow turbine engine. It has a single fan stage, 13-stage compressor (7 intermediate- and 6 high-pressure stages), single combustion chamber, and 5 stage turbine section (1 high-, 1 intermediate- and three low-pressure stages). The -22B is 10 feet, 11.4 inches (3.033 meters) long and its fan diameter is 7 feet, 0.8 inches (2.154 meters). It weighs 9,195 pounds (4,171 kilograms).

Depending on the model, the L-1011 series had a cruise speed of 520–525 knots (598–604 miles per hour, 963–972 kilometers per hour) and a maximum speed of 0.95 Mach. The service ceiling was 42,000–43,000 feet (12,802–13,106 meters). Maximum range for the long range -500 was 6,090 nautical miles (7,008 miles, 11,279 kilometers).

The Lockheed L-1011 TriStar was a very technologically advanced airliner for the time. It was the first to be certified for Category IIIc autolanding, in which the airplane’s automatic flight system could land the airplane in “zero-zero” weather conditions.

Lockheed built 250 L-1011s between 1970 and 1984. Sales were delayed because of problems with delivery of the Rolls-Royce turbofans, giving an early advantage to the competitor McDonnell DC-10, of which 446 were built.

Few TriStars remain in service. The prototype, N1011, was scrapped at Ardmore, Oklahoma, in August 1996. A portion of its fuselage, painted in Delta Air Lines livery, is on display at Atlanta-Hartsfield International Airport, Atlanta, Georgia.

The B-70 was designed as a high-altitude Mach 3 strategic bomber armed with thermonuclear bombs. The XB-70A is 196 feet, 6 inches (59.893 meters) long with a wingspan of 105 feet (32.004 meters) and an overall height of 30 feet, 8 inches (9.347 meters) . It weighs 231,215 pounds (104,877 kilograms) empty and has a maximum takeoff weight of 534,792 pounds (242,578 kilograms).

The XB-70A was powered by six General Electric YJ93-GE-3 single-spool, axial-flow turbojet engines, which used an 11-stage compressor and two-stage turbine. The engine required a special heat-resistant JP-6 fuel, and was rated at 22,000 pounds of thrust (97.86 kilonewtons), or 31,000 pounds (137.90 kilonewtons) with afterburner. The YJ93-GE-3 was 19 feet, 7.0 inches (5.969 meters) long, 4 feet, 7.0 inches (1.397 meters) in diameter, and weighed 5,200 pounds 2,359 kilograms).

The XB-70A had a maximum speed of Mach 3.1 (2,056 miles per hour, or 3,309 kilometers per hour). At 35,000 feet (10,668 meters), it could reach Mach 1.90 (1,254 miles per hour, or 2,018 kilometers per hour), and at its service ceiling of 75,550 feet (23,012 meters), it had a maximum speed of Mach 3.00 (1,982 miles per hour, or 3,190 kilometers per hour). The planned combat range for the production  bomber was 3,419 miles (5,502 kilometers) with a maximum range of 4,290 miles (6,904 kilometers).

North American Aviation XB-70A Valkyrie 62-0001 made 83 flights with a total of 160 hours, 16 minutes flight time. 62-0001 is on display at the National Museum of the United States Air Force, Wright-Patterson Air Force Base, Ohio.
