20 March 1922: USS Langley (CV-1) was commissioned as the first aircraft carrier of the United States Navy. It was a former collier, USS Jupiter (AC-3), which had been converted at the Norfolk Navy Yard, 1921–1922.
USS Langley was 542 feet (165.2 meters) long, with a beam of 65 feet, 5 inches (19.94 meters) and draft of 24 feet (7.32 meters). Her full load displacement was 14,100 tons (12,791 metric tons).

The aircraft carrier was powered by General Electric turbo-electric drive, with a total of 7,200 shaft horsepower. Steam turbines drove generators which supplied power for electric motors which drove the propeller shafts. She could make 15.5 knots (28.7 kilometers per hour).
The ship’s complement was 468 officers and men.
Defensive armament consisted of four 5-inch/51-caliber (127 millimeters × 6.477 meters) guns. These guns, firing a 50 pound (22.7 kilogram) projectile, had a maximum range of 15,850 yards (14,493 meters).

Lieutenant Commander Virgil Childers (“Squash”) Griffin, Jr., United States Navy, made the first takeoff from an aircraft carrier of the U. S. Navy when he flew a Chance Vought Corporation VE-7SF fighter from the deck of USS Langley (CV-1), 17 October 1922, while the ship was anchored in the York River along the west side of Chesapeake Bay, Maryland.
As more modern aircraft carriers Lexington and Saratoga came in to service, Langley was once again converted, this time to a sea plane tender, AV-3.

Langley, under the command of Commander Robert P. McConnell, USN, delivered a cargo of thirty-two Curtiss P-40E Warhawks for the 13th Pursuit Squadron (Provisional) from Fremantle, Western Australia, to Tjilatjap Harbor, on the southern coast of Java, Dutch East Indies. After leaving the harbor on 27 February 1942, Langley was attacked by a group of Imperial Japanese Navy Mitsubishi G4M “Betty” twin-engine medium bombers.
After evading several bomb runs, Langley was hit by six bombs. On fire and with its engine room flooded, the crew was forced to abandon ship. Langley was torpedoed by an escorting destroyer, USS Whipple (DD-217), to prevent capture.

One hundred years after USS Langley was commissioned, the aircraft carrier is the center of the American fleet. The Nimitz-class carriers are the most powerful warships ever built.
19 March 1945: Modified Avro Lancaster B Mk.I Special heavy bombers of No. 617 Squadron, Royal Air Force, attacked the railway viaduct at Arnsberg, Germany, using the 22,000 pound (9,979 kilogram) Grand Slam earth-penetrating bomb. The bomb had been first used just days before, 14 March, against another railway viaduct.
The Grand Slam was the largest and heaviest aerial bomb used during World War II. It was designed by aircraft engineer Barnes Neville Wallis, and was scaled up from his earlier, smaller “Tallboy.” (Wallis also designed the “Upkeep” Special Mine used to attack hydroelectric dams in the Ruhr Valley in 1943.)
Wallis’ idea was that a very heavy, supersonic bomb could penetrate deep into the earth and detonate, causing an “earthquake” which could destroy nearby heavily protected targets.
Tall Boy and Grand Slam Deep Penetration Bombs (British Explosive Ordnance, Part 1, Chapter 7)
The Grand Slam bomb (officially, “Bomb, D.P., 22,000-lb., Mk I”) was 25 feet, 5 inches (7.747 meters) long and had a maximum diameter of 3 feet, 10 inches (1.168 meters). When fully loaded with the explosive material, Torpex, the bomb weighed 22,400 pounds (10,160 kilograms).

The bomb case was cast of steel at the Clyde Alloy and Steel Company, Glasgow, Scotland, then, after several days of cooling, machined to its precise shape. The casing made up approximately 60% of the bomb’s total weight. At the nose, the casing had a wall thickness of 7.75 inches (19.685 centimeters).
The bomb case was filled with approximately 9,200 pounds (4,173 kilograms) of molten Torpex, with a 1 inch (2.54 centimeters) topping of TNT. Torpex was an explosive designed for torpedo warheads and depth charges. It was made up of approximately equal quantities of two other explosives, Research Department Formula X (RDX), 42%, and trinitrotoluol (TNT), 40%, mixed with 18% powdered aluminum and wax. The resulting combination was approximately 1.4 times more powerful than TNT alone. About one month was required for the explosive to cool after being poured into the bomb case.
Because of its size and weight, the only Allied bomber capable of carrying the Grand Slam was a specially modified Avro Lancaster B.I Special, flown by No. 617 Squadron, Royal Air Force, “The Dambusters.”

Wallis intended for the Grand Slam to be dropped from very high altitudes so that during its fall, it would go supersonic. The bomb had large fins that were offset 5° to the right of the centerline to cause it to rotate for stability. However, the bombers could not carry it to the planned release altitude, and it was typically dropped from approximately 9,000 feet (2,743 meters). Its very sleek design did allow it to come close to the speed of sound, however, and its stability made it a very accurate weapon. The bomb was capable of penetrating 20-foot-thick (6 meters) reinforced concrete roofs of submarine bases. ¹

19 March 1937: After her 15 hour, 47 minute, overnight flight from Oakland, California, Amelia Earhart’s Lockheed Electra 10E Special NR16020 was placed in a hangar at Wheeler Army Airfield, Honolulu, for maintenance and repair. During the flight, a propeller pitch change mechanism had failed. Inspection revealed that both propeller hubs were badly galled “due to improper or insufficient lubrication.” They were overhauled by the Army Air Corps’ Hawaiian Air Depot at Luke Field, then re-installed on the Electra.
At 11:15 a.m. on the 19th, Paul Mantz and two friends took the Electra for a test flight, then repositioned to Luke Field on Ford Island, with its longer, hard-surfaced runway, for an early morning takeoff on the second leg of the around-the-world flight.

Voskhod-2/11A57 launch vehicle on launch pad at Site 1, Baikonur Cosmodrome (Space Facts)
18 March 1965, 07:00:00 UTC (10:00:00 Moscow Time): Cosmonauts Павел Иванович Беляев (Pavel Ivanovich Belyaev) and Алексей Архипович Леонов (Alexey Arkhipovich Leonov) were launched from the Baikonur Cosmodrome aboard a Voskhod-3KD spacecraft, Восход-2 (Voskhod-2). The launch vehicle was a Voskhod 11A57 two-stage liquid-fueled rocket. Voskhod-2 entered a 167 × 475 kilometers (90 × 256 nautical miles) elliptical orbit with a period of 90 minutes, 54 seconds.
As the Voskhod entered its second orbit, co-pilot Major Leonov exited the vehicle. An expandable air lock was used. This was the first time that a human had left a vehicle in space. He floated freely, though remained connected by an umbilical. This would be known as an Extravehicular Activity (an “E-V-A,” or “space walk”). Leonov remained outside for 12 minutes, 9 seconds, establishing the first FAI World Record for Extravehicular Duration in Space. ¹

Both cosmonauts wore NPP Zvezda Berkut full-pressure suits (a “space suit”) for protection in the vacuum of space. With his suit fully inflated by pressurized air, Leonov was both larger and more rigid than was expected. He had great difficulty re-entering the Voskhod, requiring that he vent the suit pressure.
Leonov wrote about it for Air & Space:
With some reluctance I acknowledged that it was time to reenter the spacecraft. Our orbit would soon take us away from the sun and into darkness. It was then I realized how deformed my stiff spacesuit had become, owing to the lack of atmospheric pressure. My feet had pulled away from my boots and my fingers from the gloves attached to my sleeves, making it impossible to reenter the airlock feet first.
I had to find another way of getting back inside quickly, and the only way I could see to do this was pulling myself into the airlock gradually, head first. Even to do this, I would carefully have to bleed off some of the high-pressure oxygen in my suit, via a valve in its lining. I knew I might be risking oxygen starvation, but I had no choice. If I did not reenter the craft, within the next 40 minutes my life support would be spent anyway.
The only solution was to reduce the pressure in my suit by opening the pressure valve and letting out a little oxygen at a time as I tried to inch inside the airlock. At first I thought of reporting what I planned to do to mission control. But I decided against it. I did not want to create nervousness on the ground. And anyway, I was the only one who could bring the situation under control.
But I could feel my temperature rising dangerously high, with a rush of heat from my feet traveling up my legs and arms, due to the immense physical exertion all the maneuvering involved. It was taking longer than it was supposed to. Even when I at last managed to pull myself entirely into the airlock, I had to perform another almost impossible maneuver. I had to curl my body around in order to close the airlock, so pasha could activate the mechanism to equalize pressure between it and the spacecraft.
Once Pasha was sure the hatch was closed and the pressure had equalized, he triggered the inner hatch open and I scrambled back into the spacecraft, drenched with sweat, my heart racing.

On 19 March, Voshkod-2’s apogee set a Fédération Aéronautique Internationale (FAI) World Record for Altitude in Elliptical Orbit of 497,7 kilometers (268.7 nautical miles/309.3 statute miles). ²
The space craft began to lose pressure, with it’s oxygen tanks dropping by two-thirds during Orbit 13. It was thought that the mission might have to be cut short.
It was planned for Voskhod-2 to reenter on the 16th orbit, however the automatic landing system failed to fire the spacecraft’s retrorockets. Using the Voskhod’s primary engine, a manual reentry was initiated during the 18th orbit. The crew also had to orient the spacecraft manually, and this caused them a delay of 46 seconds before initiating reentry. They overshot their expected landing point by approximately 2,000 kilometers (1,250 miles).
Voshkod-2 landed in remote area of Perm Krai at 09:02:17 UTC on 19 March. The duration of the flight was 1 day, 2 hours, 2 minutes, 17 seconds.
Having landed in a dense forest hundreds of miles from the nearest recovery teams, Belyaev and Leonov were were located about four hours later and a rescue team arrived the next day. A landing zone was cut in the forest and the cosmonauts were flown out by helicopter on 21 March.
Voskhod-2 landed in dense forest. The cosmonauts were not recovered for two days.

18 March 1945: At the Naval Airplane Factory, El Segundo, California (at the southeast corner of Los Angeles Airport, now best known as LAX), Douglas Aircraft Company Director of Flight Test LaVerne Ward (“Brownie”) Browne took the prototype XBT2D-1 Dauntless II, Bu. No. 9085, for its first flight.
He later commented, “I wish I could tell of some dramatic incident that occurred. There wasn’t any. I just floated around up there for an hour and a half and brought her down. But I did do something that’s unprecedented, I believe, for a first trip. The airplane handled so well that I put it through rolls and Immelmanns to check it for maneuverability.”

The XBT2D-1 would be ordered into production as the Douglas AD-1 Skyraider.
Designed by Douglas’ Chief Engineer, Edward Henry Heinemann, the XBT2D-1 was a single-place, single-engine attack bomber capable of operation from the U.S. Navy’s aircraft carriers. The prototype was 39 feet, 5 inches (12.014 meters) long with a wingspan of 50 feet, ¼ inch (15.246 meters) and overall height of 15 feet, 7½ inches (4.763 meters). The airplane had an empty weight of 10,093 pounds (4,578 kilograms) and maximum weight of 17,500 pounds (7,938 kilograms).
The first four XBT2D-1 prototypes were powered by an air-cooled, supercharged, 3,347.662-cubic-inch-displacement (54.858 liter) Wright Aeronautical Division R3350-8 (Cyclone 18 779C18BB1) twin-row 18-cylinder radial engine rated at 2,100 horsepower at 2,400 r.p.m., and 2,400 horsepower at 2,600 r.p.m., for takeoff. The next 20 airplanes built utilized the R3350-24W (Cyclone 18 825C18BD1) which had a takeoff power rating of 2,500 horsepower at 2,900 r.p.m.
Both engines had a compression ration of 6.5:1 and a propeller drive reduction ratio of 0.4375:1. They differed in external dimensions and weight, with the –24W being both longer and heavier.

The XBT2D-1 had a maximum speed of 375 miles per hour (604 kilometers per hour) at 13,600 feet (4,145 meters) and normal cruise speed of 164 miles per hour (264 kilometers per hour).
The first XBT2D-1, Bu. No. 9085, was sent to NAS Patuxent River, Maryland, for further testing. The second, 9086, went to NACA Ames at Moffet Field, California, where it underwent testing from 11 March 1946 to 4 September 1947.

3,180 Skyraiders in 11 variants were built at the Douglas Aircraft Company’s El Segundo, California, plant from 1945 to 1957. The attack bomber was widely used during the Korean War and the Vietnam War. It was utilized for many purposes but is best known for its close support missions during combat rescue operations. After 1962, the AD-series aircraft still in service were redesignated A-1E through A-1J.

The most numerous Skyraider variant was the AD-6 (A-1H), of which 713 were produced by Douglas. The AD-6 was 38 feet, 10 inches (11.836 meters) long with a wingspan of 50 feet, 9 inches (15.469 meters) and overall height of 15 feet, 8¼ inches (4.782 meters). Its empty weight was 11,968 pounds (5,429 kilograms) and gross weight was 18,106 pounds (8,213 kilograms). The maximum takeoff weight (MTOW) for the AD-6 was 25,000 pounds (11,340 kilograms).

The Douglas AD-6 was powered by an air-cooled, supercharged, direct-fuel-injected, 3,347.662-cubic-inch-displacement (54.858 liter), Wright Aeronautical Division R-3350-26WA (Cyclone 18 836C18CA1) twin-row 18-cylinder radial engine, with water/alcohol injection. This engine has a compression ratio of 6.71:1. The R-3350-26W has a Normal Power rating of 2,300 horsepower at 2,600 r.p.m., and a Takeoff/Military Power rating of 2,700 horsepower at 2,900 r.p.m., using 115/145 aviation gasoline. The engine drives a four-bladed Aeroproducts constant-speed propeller with a diameter of 13 feet, 6 inch (4.115 meters) through a 0.4375:1 gear reduction. The engine is 4 feet, 7.62 inches (1.413 meters) in diameter and 6 feet, 6.81 inches (2.002 meters) long. It weighs 2,848 pounds (1,292 kilograms), dry.
The AD-6/A-1H Skyraider had a cruise speed of 198 miles per hour (319 kilometers per hour) and a maximum speed of 322 miles per hour (518 kilometers per hour). The ceiling was 29,400 feet (8,961 meters) and its combat radius carrying 2,000 pounds (907 kilograms) of ordnance was 275 miles (443 kilometers).

The AD-6 Skyraider was armed with four 20mm AN-M2 autocannons, with two in each wing, and 200 rounds of ammunition per gun. The guns fired explosive projectiles with a muzzle velocity of 2,850 feet per second (869 meters per second), and had a rate of fire of 600–700 rounds per minute. The AD-6 could carry 8,000 pounds (3,629 kilograms) of bombs, rockets, gun pods and external fuel tanks from the 15 hard points and pylons under the wings and fuselage.

Many United States Navy and Marine Corps Skyraiders were transferred to the U.S. Air Force. The Air Force retained the Navy’s Bureau of Aeronautics serial numbers (“Bu. No.”) but added two digits corresponding to the fiscal year in which each airplane was originally contracted. This resulted in serial numbers similar, though longer, than customary in the Air Force and Army numbering system.
The oldest Skyraider in existence is XBT2D-1 Bu. No. 9102. Formerly on display at NAS Oceana, Virginia Beach, Virginia, the airplane was transferred to The Intrepid Sea, Air & Space Museum in New York City for restoration and preservation.

LaVerne Ward Browne was born at Orange, California, 9 December 1906. He was the third child of Edwin J. Brown, a farm worker, and Phebe Alice Proctor Brown. He studied law at the University of Southern California (USC).
In 1928, Brown learned to fly at the Hancock College of Aeronautics, Santa Maria, California. He then worked as a pilot for Transcontinental and Western Airways, flying the Douglas DC-2. He was also commissioned as a second lieutenant in the United States Army Air Corps Reserve.
Browne married Miss Dorothy Leonore Bach at Los Angeles, California, 28 January 1926. They had a daughter, Barbara May Browne, born 6 December 1926, but later divorced. One 12 June 1933, Browne married Harriette Fitzgerald Dodson at Norfolk, Virginia.
From 1931 to 1941, under the pseudonym “John Trent,” Browne performed in sixteen Hollywood movies, including “I Wanted Wings,” with William Holden, Ray Milland and Veronica Lake. He played the character “Tailspin Tommy Tompkins” in four: “Danger Flight,” “Sky Patrol,” “Stunt Pilot,” and “Mystery Plane.”
Browne worked for Douglas Aircraft Company from 1942 to 1957. He died 12 May 1966 at Palos Verdes, California, at the age of 59 years.
