13 July 1968: The first production General Dynamics FB-111A supersonic strategic bomber successfully completed a 30-minute maiden flight at Carswell Air Force Base, Fort Worth, Texas. The FB-111A differed from the F-111A fighter bomber with the substitution of a larger wing, originally designed for the F-111B, giving the bomber a 7 foot (2.134 meter) increase in wingspan. The landing gear was strengthened, the bomb bay enlarged, and it had more powerful engines.

Aardvark (Orycteropus afer)

The airplane’s very long nose earned the nickname “Aardvark,” but this did not become official until 1996.

67-0159 was delivered to the U.S. Air Force 4 September 1968 and assigned to the Air Force Flight Test Center, Edwards Air Force Base, California. (The first six production airplanes were used for flight testing.)

67-0159 was later converted to the F-111G configuration. In 1980 it was sent to the Sacramento Air Logistics Center to test weapons modifications and received a spectacular white and orange paint scheme. It was retired in 1990. 67-0159 is in the collection of the National Museum of the United States Air Force. It is on loan and now on display at the Aerospace Museum of California, Sacramento, California.

The General Dynamics FB-111A is a two-place, twin-engine, strategic bomber with variable-sweep wings, assigned to the Strategic Air Command. It is 73.54 feet (22.415 meters) long. The wingspan varies from a maximum 70.0 feet (21.336 meters) when fully extended, and a minimum 33.96 feet (10.351 meters) when swept fully aft. Overall height is 17.04 feet (5.194 meters).

The wings of the FB-111A have a total area of 550 square feet (51.10 square meters). When fully extended, the wings’ leading edges are swept aft to 16.0°. The angle of incidence at the root is +1° and -3° at the tip. There is 1.0° dihedral.

The Aardvark’s empty weight is 47,481 pounds (21,537 kilograms). Normal maximum takeoff weight is 116,115 pounds (52,669 kilograms), and the maximum overload takeoff weight is or 119,243 pounds (54,088 kilograms).

The aircraft is powered by two Pratt & Whitney TF30-P-107 engines. This is a two-spool axial-flow turbofan engine with afterburner. It has a 3-stage fan section, 13-stage compressor section (6 low- and 7 high-pressure stages) and 4-stage turbine (1 high- and 3 low-pressure stages). The -107 has a maximum continuous power rating of 10,800 pounds of thrust (48.041 kilonewtons) at 14,150 r.p.m., N2 (static thrust, at Sea Level), and a maximum power rating of 20,350 pounds (90.521 kilonewtons) at 14,550 r.p.m., N2 (45 minute limit) The T30-P-107 is 3 feet, 2.12 inches (0.968 meters) in diameter, 20 feet, 1.4 inches (6.132 meters) long,  and weighs 4,121 pounds (1,869 kilograms).

The FB-111A has an average cruise speed of 415–442 knots (478–509 miles per hour/769-819 kilometers per hour), depending on the mission profile. It’s maximum speed at 50,000 feet (15,240 meters) is 1,262 knots (1,452 miles per hour/2,337 kilometers per hour)—Mach 2.20. The bomber’s service ceiling varies from 50,390 feet to 56,380 feet (15,359–17,185 meters), again, depending on the mission profile. The maximum combat range is 4,920 nautical miles (5,662 statute miles/9,112 kilometers). The airplane can carry as many as six 600 gallon (2,271 liter) external tanks on underwing pylons. This gives the Aardvark a maximum ferry range of 4,313 nautical miles (4,963 statute miles/7,988 kilometers).

The FB-111A could carry weapons in an internal bomb bay or on underwing hardpoints. It could be armed with up to 37,500 pounds (17,010 kilograms) of conventional bombs; or six AGM-69A Short Range Attack Missiles (SRAM). The Aardvark could carry maximum of six nuclear weapons (B-43, B-57 or B-61).

In addition to a prototype (63-9783, which was converted from the last production F-111A) General Dynamics built 76 FB-111A strategic bombers. With the introduction of the Rockwell B-1B Lancer, the FB-111As remaining in service were converted to F-111G tactical fighter bombers. They were retired by 2003.

The Royal Australian Air Force bought 15 of the F-111Gs. By 2007, these had also been taken out of service.

10 July 1940

The Battle of Britain begins.

Before Germany could mount Operation Sea Lion, a cross-channel invasion of the British Isles, it needed to have complete air superiority over the invasion fleet. Because of the Luftwaffe‘s greater numbers and modern aircraft, German military leadership believed this could best be accomplished by defeating the Royal Air Force in air-to-air combat.

The Royal Air Force had been conserving their limited numbers of pilots and aircraft up to this point in the war. Germany’s plan was to send its bombers against targets that the R.A.F. would be forced to defend. The escorting Messerschmitt Bf 109s (also referred to as the Me 109) would then shoot down the Boulton Paul Defiants and Bristol Blenheims. But the Hawker Hurricanes and Supermarine Spitfires were up to the task. While the Hurricanes went after the Luftwaffe’s Dornier 17 and Heinkel He 111 bombers, the Spitfires engaged their Bf 109 fighter escorts.

Britain used a system of radar-directed ground control of its fighter squadrons. The result was that though both sides lost about the same number of aircraft, the Battle of Britain was a decisive victory for Great Britain. Germany was forced to give up on its plans for an invasion of England.

During a speech the House of Commons, 20 August 1940, Prime Minister Winston Churchill referred to the pilots of Fighter Command when he said,

The gratitude of every home in our Island, in our Empire, and indeed throughout the world, except in the abodes of the guilty, goes out to the British airmen who, undaunted by odds, unwearied in their constant challenge and mortal danger, are turning the tide of the world war by their prowess and by their devotion. Never in the field of human conflict was so much owed by so many to so few.”

Ever since, the Royal Air Force has been known as “The Few.”

7 July 1985: The Strategic Air Command received the first operational Rockwell B-1B Lancer, serial number 83-0065, Star of Abilene, at Dyess Air Force Base, Abilene, Texas. It flew for 17 years, 7 months, 23 days before being retired 1 March 2003 and preserved at Dyess.

The Rockwell B-1B is a long-range, supersonic bomber with variable-sweep wings. It is operated by two pilots and two combat systems officers. The Rockwell B-1B is 146 feet (44.501 meters) long, with the wing span varying from 79 feet (24.079 meters) to 137 feet (41.758 meters). It is 34 feet (10.363 meters) high at the top of the vertical fin. The bomber’s empty weight is 192,000 pounds (87,090 kilograms) and the Maximum Takeoff Weight (MTOW) is 477,000 pounds (216,364 kilograms).

The B-1B is powered by four General Electric F101-GE-102 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 17,390 pounds of thrust (77.35 kilonewtons), and 30,780 pounds of thrust (136.92 kilonewtons) with afterburner. The F101-GE-102 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 B-1B has a maximum speed of Mach 1.25 (830 miles per hour (1,336 kilometers per hour) at high altitude, or 0.92 Mach (700 miles per hour, 1,127 kilometers per hour) at 200 feet (61 meters). The Lancer has a service ceiling of 60,000 feet (18,288 meters), and an unrefueled range of 7,456 miles (11,999 kilometers).

It can carry up to 84 Mk.82 500-pound bombs, 24 Mk.84 2,000-pound bombs, or other weapons.

100 B-1B Lancers were built by Rockwell International’s aircraft division at Air Force Plant 42, Palmdale, California, between 1983 and 1988. As of February 2018, 62 B-1B bombers are in the active Air Force inventory.
