L-8 Canal
L-8, later renamed ''America'' and popularly known as the "Ghost Blimp", was a United States Navy L-class airship whose crew disappeared over the Pacific Ocean on August 16, 1942. At 11:15 a.m., several hours after the airship lifted off from Treasure Island, San Francisco, California, L-8 reappeared off the shore of Ocean Beach near Fort Funston. L-8 briefly made contact with the ground at Ocean Beach, causing damage to the airship, then drifted over San Francisco and crashed on Bellevue Avenue, Daly City. No traces of its crewmen, Lieutenant Ernest DeWitt Cody and Ensign Charles Adams, have ever been found. Background The L-class was a series of non-rigid airships ( blimps), produced for the United States Navy in 1937, based upon the small commercial airships produced by the Goodyear Aircraft Company that were used for advertising Goodyear tires. After the United States declared war on Japan in response to Pearl Harbor, the Imperial Japanese Navy sank at least half a ...

Attack On Pearl Harbor
The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 8:00a.m. (local time) on Sunday, December 7, 1941. The United States was a neutral country at the time; the attack led to its formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. Japan intended the attack as a preventive action. Its aim was to prevent the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and those of the United States. Over the course of seven hours there were coordinated Japanese attacks on the US-held Philippines, Guam, and Wake Island and on the British Empire ...

North American B-25 Mitchell
The North American B-25 Mitchell is an American medium bomber that was introduced in 1941 and named in honor of Major General William "Billy" Mitchell, a pioneer of U.S. military aviation. Used by many Allied air forces, the B-25 served in every theater of World War II, and after the war ended, many remained in service, operating across four decades. Produced in numerous variants, nearly 10,000 B-25s were built. These included several limited models such as the F-10 reconnaissance aircraft, the AT-24 crew trainers, and the United States Marine Corps' PBJ-1 patrol bomber. Design and development The Air Corps issued a specification for a medium bomber in March 1939 that was capable of carrying a payload of over at North American Aviation used its NA-40B design to develop the NA-62, which competed for the medium bomber contract. No YB-25 was available for prototype service tests. In September 1939, the Air Corps ordered the NA-62 into production as the B-25, along with the ...

Antisubmarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instances of ...

The state capital is Trenton, and the most populous city is Newark. With the exception of Warren County, all of the state's 21 counties lie within the combined statistical areas of New York City or Philadelphia. New Jersey was first inhabited by Native Americans for at least 2,800 years, with the Lenape being the dominant group when Europeans arrived in the early 17th century. Dutch and Swedish colonists founded the first European settlements in the state. The British later seized control o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NAS Lakehurst
Lakehurst Maxfield Field, formerly known as Naval Air Engineering Station Lakehurst (NAES Lakehurst), is the naval component of Joint Base McGuire–Dix–Lakehurst (JB MDL), a United States Air Force-managed joint base headquartered approximately east-southeast of Trenton in Manchester Township and Jackson Township in Ocean County, New Jersey, United States. It is primarily the home to Naval Air Warfare Center Aircraft Division Lakehurst, although the airfield supports several other flying and non-flying units as well. Its name is an amalgamation of its location and the last name of Commander Louis H. Maxfield, who lost his life when the R-38/USN ZR-2 airship crashed during flight on 24 August 1921 near Hull, England. When it was consolidated with McGuire Air Force Base and Fort Dix in October 2009, it became the naval component of JB MDL – a United States Air Force– controlled installation – and was placed under the 87th Air Base Wing. However, as with all joint bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weather Balloon
A weather balloon, also known as sounding balloon, is a balloon (specifically a type of high-altitude balloon) that carries instruments aloft to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde. To obtain wind data, they can be tracked by radar, radio direction finding, or navigation systems (such as the satellite-based Global Positioning System, GPS). Balloons meant to stay at a constant altitude for long periods of time are known as ''transosondes''. Weather balloons that do not carry an instrument pack are used to determine upper-level winds and the height of cloud layers. For such balloons, a theodolite or total station is used to track the balloon's azimuth and elevation, which are then converted to estimated wind speed and direction and/or cloud height, as applicable. Weather balloons are launched around the world for observations used to diagnose current conditions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Los Angeles
The Battle of Los Angeles, also known as the Great Los Angeles Air Raid, is the name given by contemporary sources to a rumored attack on the continental United States by Imperial Japan and the subsequent anti-aircraft artillery barrage which took place from late 24 February to early 25 February 1942, over Los Angeles, California. The incident occurred less than three months after the U.S. entered World War II in response to the Imperial Japanese Navy's surprise attack on Pearl Harbor, and one day after the bombardment of Ellwood near Santa Barbara on 23 February. Initially, the target of the aerial barrage was thought to be an attacking force from Japan, but speaking at a press conference shortly afterward, Secretary of the Navy Frank Knox called the purported attack a "false alarm". Newspapers of the time published a number of reports and speculations of a cover-up to conceal an actual invasion by enemy airplanes. When documenting the incident in 1949, the United States Coas ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Bombardment Of Fort Stevens
The Bombardment of Fort Stevens occurred in June 1942, in the American Theater and the Pacific Theater of World War II. The Imperial Japanese submarine ''I-25'' fired on Fort Stevens, which defended the Oregon side of the Columbia River's Pacific entrance. Bombardment The Imperial Japanese Navy submarine , commanded by Akiji Tagami, had been assigned to sink enemy shipping and attack the enemy on land with its 14 cm deck gun. Transporting a Yokosuka E14Y seaplane, the submarine was manned by a crew of 97. On 21 June 1942, ''I-25'' had entered U.S. coastal waters, following fishing boats to avoid the mine fields in the area. Late that night, Commander Tagami ordered his crew to surface his submarine at the mouth of the Columbia River. His target was Fort Stevens, which dated to the American Civil War and was armed with more or less obsolete Endicott era artillery, including mortars and several and disappearing guns. Tagami ordered the deck gun crew to open fire on F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombardment Of Ellwood
The Bombardment of Ellwood during World War II was a naval attack by a Japanese submarine against United States coastal targets near Santa Barbara, California. Though the damage was minimal, the event was key in triggering the West Coast invasion scare and influenced the decision to intern Japanese-Americans. The event also marked the first shelling of the North American mainland during the conflict. Background Following the surprise attack on Pearl Harbor in Hawaii, seven Japanese submarines patrolled the American West Coast. They sank two merchant ships and damaged six more, skirmishing twice with U.S. Navy air or sea forces. By the end of December, the submarines had all returned to friendly waters to resupply. However, several had gone to Kwajalein and would pay a return visit to American waters. One of these was the Imperial Japanese Navy submarine . The ''I-17'' displaced when submerged and was long. Her armament included six torpedo tubes and 17 torpedoes, plus a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
