Timeline Of US Navy Airship Units (pre-WWII)
Unlike later blimp squadrons, which contained several airships, the large rigid airship units consisted of a single airship and, in the case of the USS ''Akron'' and USS ''Macon'', a small contingent of fixed-wing aircraft. 1910s 1919 A semi rigid airship, the O-1, is purchased from Italy October, The ZR-2 (R38) is placed under contract from Britain, where construction had been started on it as the ''R38.'' 1920s 1921 The first large US airship hangar is built at Lakehurst, New Jersey On the fourth test flight of R-38 severe control inputs at low altitude and high speed cause the structural failure of the airship with the loss of the majority of the crew. Sixteen of the men killed were USN training to fly the ship back to Cape May, NJ. The ZR-2 (R38) crashed before the US Navy could take delivery of the airship; therefore ZR-2 did not officially receive its US designation, though it was painted with its planned Navy designation. 1922 The first American-built rigid ...

O-1 (airship)
__NOTOC__ The SCDA O-1 was an Italian semi-rigid airship, the only true semi-rigid airship to serve with the United States Navy. Operational service The O-1 was ordered from Stabilimento Costruzioni Dirigibili ed Aerostati (SCDA) by the United States Navy. Its first flight was made at Ciampino, Italy, on 27 March 1919. Following tests, it was sent from Genoa, Italy, leaving on 24 May 1919. It was sent to Akron for study and was then erected at the airship base at Cape May, New Jersey. The O-1 first flew in the USA on 16 September 1919. While operating from Cape May, the O-1 lost all power on a landing approach and was blown to near Pennsville, New Jersey where the crew managed to land it. The O-1 was eventually returned to service and while on temporary duty at Hampton Roads the O-1 was used to launch gliders designed to be anti-aircraft targets. The date the O-1 was scrapped is not known, but was probably in the winter of 1921–22. Operators ; *United States Navy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Macon (ZRS-5)
USS ''Macon'' (ZRS-5) was a rigid airship built and operated by the United States Navy for scouting and served as a "flying aircraft carrier", designed to carry biplane parasite aircraft, five single-seat Curtiss F9C Sparrowhawk for scouting or two-seat Fleet N2Y-1 for training. In service for less than two years, in 1935 the ''Macon'' was damaged in a storm and lost off California's Big Sur coast, though most of the crew were saved. The wreckage is listed as the USS ''Macon'' Airship Remains on the U.S. National Register of Historic Places. Less than shorter than ''Hindenburg'', both ''Macon'' and her sister ship were among the largest flying objects in the world in terms of length and volume. Although both of the hydrogen-filled, Zeppelin-built ''Hindenburg'' and LZ 130 ''Graf Zeppelin II'' were longer, the two American-built sister naval airships still hold the world record for helium-filled rigid airships. Construction USS ''Macon'' was built at the Goodyear Airdock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airships
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air Powered aircraft, under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen gas, hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the Chitty Bang Bang (airship), ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of The United States Navy
The history of the United States Navy divides into two major periods: the "Old Navy", a small but respected force of sailing ships that was notable for innovation in the use of ironclads during the American Civil War, and the "New Navy" the result of a modernization effort that began in the 1880s and made it the largest in the world by 1943. The United States Navy claims October 13, 1775 as the date of its official establishment, when the Second Continental Congress passed a resolution creating the Continental Navy. With the end of the American Revolutionary War, the Continental Navy was disbanded. Under the Presidency of John Adams, merchant shipping came under threat while in the Mediterranean by Barbary pirates from four North African States. This led to the Naval Act of 1794, which created a permanent standing U.S. Navy. The original six frigates were authorized as part of the Act. Over the next 20 years, the Navy fought the French Republic Navy in the Quasi-War (1798â ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressure Height
A rigid airship is a type of airship (or dirigible) in which the envelope is supported by an internal framework rather than by being kept in shape by the pressure of the lifting gas within the envelope, as in blimps (also called pressure airships) and semi-rigid airships. Rigid airships are often commonly called Zeppelins, though this technically refers only to airships built by the Luftschiffbau Zeppelin company. In 1900, Count Ferdinand von Zeppelin successfully performed the maiden flight of his first airship; further models quickly followed. Prior to the First World War, Germany was a world leader in the field, largely attributable to the work of von Zeppelin and his Luftschiffbau Zeppelin company. During the conflict, rigid airships were tasked with various military duties, which included their participation in Germany's strategic bombing campaign. Numerous rigid airships were produced and employed with relative commercial success between the 1900s and the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Point Sur Lighthouse
Point Sur Lighthouse is a lightstation at Point Sur south of Monterey, California at the peak of the rock at the head of the point. It was established in 1889 and is part of Point Sur State Historic Park. The light house is tall and above sea level. As of 2016, and for the foreseeable future the light is still in operation as an essential aid to navigation. Point Sur is the only complete turn-of-the-20th-century lightstation open to the public in California. Three-hour walking tours guided by volunteers are available on Wednesdays and weekends throughout the year. Light sources The lighthouse has had four different light sources during its history. First, it had an oil wick lamp, and then an oil vapor lamp. Three different fuels were used: whale oil, lard oil, and kerosene. Electricity wasn't introduced to the surrounding area and light house until the 1950s. Since Point Sur was a major point used for navigation, it was equipped with first-order Fresnel lens, the larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

USS Akron (ZRS-4) In Flight Over Manhattan, Circa 1931-1933
USS ''Akron'' (ZRS-4) was a helium-filled rigid airship of the U.S. Navy, the lead ship of her class, which operated between September 1931 and April 1933. It was the world's first purpose-built flying aircraft carrier, carrying F9C Sparrowhawk fighter planes, which could be launched and recovered while it was in flight. With an overall length of , ''Akron'' and her sister ship were among the largest flying objects ever built. Although LZ 129 ''Hindenburg'' and LZ 130 ''Graf Zeppelin II'' were some longer and slightly more voluminous, the two German airships were filled with hydrogen, and so the two US Navy craft still hold the world record for the largest helium-filled airships. ''Akron'' was destroyed in a thunderstorm off the coast of New Jersey on the morning of 4 April 1933, killing 73 of the 76 crewmen and passengers. The accident involved the greatest loss of life in any airship crash. Technical description The airship's skeleton was built of the new lightweight ...
