Sparoair
Sparoair was a family of air-launched sounding rockets developed by the United States Navy in the late 1950s and early 1960s. Based on the Sparrow air-to-air missile, three versions of the rocket were developed; although some launches were successful, the system did not enter operational service. Sparoair I and II Sparoair was developed by the Naval Missile Center, as a two-stage development of the Sparrow III air-to-air missile. Propelled by two Sparrow rocket motors mounted in tandem, the Sparoair could be launched from F3H (F-3) Demon and F4D (F-6) Skyray fighter aircraft, and was capable of lifting a payload to an apogee of . The Sparoair I was the original version of the rocket, launched using an ejection system and a lanyard for firing; after that proved unreliable in flight testing, the Sparoair II was developed that utilised a rail launch with ignition prior to release from the aircraft. Eight launches of Sparoair II vehicles had been conducted by 1961. Each Sparoair ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Missile Test Center
Pacific Missile Test Center (PMTC) is the former name of the current Naval Air Warfare Center, Weapons Division. The name of the center was the Naval Air Missile Test Center prior to PMTC. It is located at Naval Base Ventura County/Naval Air Station Point Mugu in Ventura County, California. The nearest city to the installation is Oxnard. The Naval Air Warfare Center consists of both the NAS Point Mugu airfield and a rocket launching site for the U.S. Navy. The center has been an active development and test facility for the Navy since the late 1940s. Among the missiles developed and tested there include the Sparrow family and the Phoenix, and AMRAAM air-to-air missiles and the Regulus surface-to-surface missile in addition to numerous prototypes of military rockets and sounding rockets. History It was originally built for anti-aircraft training during World War II. The base later shifted from traditional anti-aircraft munitions training to become a test center for anti-aircra ...

AIM-7 Sparrow
The AIM-7 Sparrow (Air Intercept Missile) is an American, medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, and United States Marine Corps, as well as other various air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s. It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM. The early Sparrow was intended primarily for use against larger targets, especially bombers and had numerous operational limitations in other uses. Against smaller targets, the need to receive a strong reflected radar signal made achieving lock-on at the missile's effective range difficult. As the launching aircraft's own radar needed to be pointed at the target throughout the engagement, this meant that in fighter-vs-fighter combat, the enemy fighter would often approa ...

Sounding Rocket
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are used to launch instruments from 48 to 145 km (30 to 90 miles) above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km (25 miles) and the minimum for satellites is approximately 121 km (75 miles). Certain sounding rockets have an apogee between 1,000 and 1,500 km (620 and 930 miles), such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 270–450-kg (600–1,000-pound) payloads into the exoatmospheric region between 97 and 201 km (60 and 125 miles).

Point Mugu
Point Mugu (, Chumash: ''Muwu'') is a cape or promontory within Point Mugu State Park on the Pacific Coast in Ventura County, near the city of Port Hueneme and the city of Oxnard. The name is believed to be derived from the Chumash Indian term "Muwu", meaning "beach", which was first mentioned by Cabrillo in his journals in 1542. Mugu Lagoon is a salt marsh just upcoast from the promontory within the Naval Base Ventura County formerly called the Naval Air Station Point Mugu. History The name derives from Muwu ( Ventureño: "Beach"), which was the name of a Chumash village at Point Mugu during pre-colonial times. The village of Muwu (CA-VEN-11) had the highest population of any coastal Chumash settlements along the Santa Monica Mountains. Muwu was a ceremonial center and the ancient capital of Lulapin, a major political unit of Chumash territory which stretched from modern day Los Angeles County to Santa Barbara in the north. The territory stretched for along the coast, and at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Navy
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 allies or partner nations of the United States as of 2015. It has the highest combined battle fleet tonnage (4,635,628 tonnes as of 2019) and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction, and five other carriers planned.

McDonnell F3H Demon
The McDonnell F3H Demon is a subsonic swept-wing United States Navy carrier-based jet fighter aircraft. The successor to the F2H Banshee, the Demon was originally designed to use the Westinghouse J40 engine, but had to be redesigned to accept the Allison J71 after the J40 suffered severe problems and was ultimately abandoned.Angelucci and Bowers 1987, p. 304. Though it lacked sufficient power for supersonic performance, it complemented day fighters such as the Vought F8U Crusader and Grumman F11F Tiger as an all-weather, missile-armed interceptor until 1964. It was withdrawn before it could serve in Vietnam when both it and the Crusader were replaced on ''Forrestal''-class and similar supercarriers by the McDonnell Douglas F-4 Phantom II. McDonnell's Phantom, which was equally capable against ground, fighter, and bomber targets, bears a strong family resemblance, as it was conceived as an advanced development of the Demon.

Douglas F4D Skyray
The Douglas F4D Skyray (later redesignated F-6 Skyray) is an American carrier-based fighter/interceptor built by the Douglas Aircraft Company. Although it was in service for a relatively short time (1956–1964) and never entered combat, it was the first carrier-launched aircraft to hold the world's absolute speed record, at 752.943 mph,Angelluci 1987, p. 92. (1211.744 km/h) and was the first United States Navy and United States Marine Corps fighter that could exceed Mach 1 in level flight.Francillon 1979, p. 480. It was the last fighter produced by the Douglas Aircraft Company before it merged with McDonnell Aircraft and became McDonnell Douglas. The F5D Skylancer was an advanced development of the F4D Skyray that did not go into service. Design and development The Skyray was designed to meet a Navy requirement issued in 1947 for a fighter aircraft that could intercept and destroy an enemy aircraft at an altitude of 50,000 ft (15,240 m) within five minu ...

Apogee
An apsis (; ) is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, the apsides of the Earth are called the aphelion and perihelion. General description There are two apsides in any elliptic orbit. The name for each apsis is created from the prefixes ''ap-'', ''apo-'' (), or ''peri-'' (), each referring to the farthest and closest point to the primary body the affixing necessary suffix that describes the primary body in the orbit. In this case, the suffix for Earth is ''-gee'', so the apsides' names are ''apogee'' and ''perigee''. For the Sun, its suffix is ''-helion'', so the names are ''aphelion'' and ''perihelion''. According to Newton's laws of motion, all periodic orbits are ellipses. The barycenter of the two bodies may lie well within the bigger body—e.g., the Earth–Moon barycenter is about 75% of the way from Earth's center to its surface. If, compared to the larger mass, the smaller mass is negligible (e.g., f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McDonnell Douglas F-4 Phantom II
The McDonnell Douglas F-4 Phantom II is an American tandem two-seat, twin-engine, all-weather, long-range supersonic jet interceptor and fighter-bomber originally developed by McDonnell Aircraft for the United States Navy.Swanborough and Bowers 1976, p. 301. Proving highly adaptable, it entered service with the Navy in 1961 before it was adopted by the United States Marine Corps and the United States Air Force, and by the mid-1960s it had become a major part of their air arms. Phantom production ran from 1958 to 1981 with a total of 5,195 aircraft built, making it the most produced American supersonic military aircraft in history, and cementing its position as an iconic combat aircraft of the Cold War."F-4 Phantoms Phabulous 40th" Boeing.

Low Altitude Bombing System
Toss bombing (sometimes known as loft bombing, and by the U.S. Air Force as the Low Altitude Bombing System, LABS) is a method of bombing where the attacking aircraft pulls upward when releasing its bomb load, giving the bomb additional time of flight by starting its ballistic path with an upward vector. The purpose of toss bombing is to compensate for the gravity drop of the bomb in flight, and allow an aircraft to bomb a target without flying directly over it. This is to avoid overflying a heavily defended target, or to distance the attacking aircraft from the blast effects of a nuclear (or conventional) bomb. Bomb tactics Pop-up In pop-up bombing, the pilot approaches from low altitude in level flight, and on cues from the computer pulls up at the last moment to release the bomb. Release usually occurs between 20° and 75° above the horizontal, causing the bomb to be tossed upward and forward, much like an underarm throw of a ball. Level toss Although "pop-up" bombing is ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
