2.25-Inch Sub-Caliber Aircraft Rocket
The 2.25-Inch Sub-Caliber Aircraft Rocket, or SCAR, was an American unguided rocket developed by the United States Navy during World War II and used for sub-caliber rocket training. Capable of simulating the aerial rockets then coming into operational service, the SCAR was used to train pilots in the use of the new type of weapon, and continued in service throughout the 1950s. Development With the introduction of the 3.5-Inch and 5-Inch Forward Firing Aircraft Rockets, a need arose to train aircraft pilots in the proper tactics for the use of the new weapons. This requirement resulted in the development of a dedicated training rocket by the U.S. Navy.Parsch 2004 Designated 2.25-Inch Sub-Caliber Aircraft Rocket, the resulting rocket was a joint project between the Bureau of Ordnance and the National Defense Research Committee. As its name implied, the rocket was designed as a sub-calibre weapon compared to the FFAR, being only in diameter, but weighted to be ballistically simi ...

Unguided Rocket
In military terminology, a rocket is a self-propelled, generally unguided, weapon-system powered by a rocket engine. Though used primarily as medium- and long-range artillery systems, historically rockets have also seen considerable use as air-to-surface weapons, some use as air-to-air weapons, and even (in a few cases) as surface-to-air devices. Examples of modern surface-to-surface rocket systems include the Soviet BM-27 Uragan and the American M270 Multiple Launch Rocket System. In military parlance, a rocket differs from a missile primarily by lacking an active guidance system; early missiles became known as "guided rockets" or "guided missiles". Some rockets were developed as unguided systems and later upgraded to guided versions, like the GMLRS, and these generally retain the term "rocket" instead of becoming "missiles". Rockets or missiles that travel underwater, like the VA-111 Shkval, are known as "torpedoes", whatever their propulsion system. Early development The ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sub-caliber Training
Sub-caliber training is used to save wear and expense when training with a larger gun by use of smaller weapons (sometimes, but not always, with very similar ballistic characteristics). The smaller weapons could be inserted into the larger weapon's barrel, externally attached to the barrel or mounted above the weapon. Examples include 2.25-Inch Sub-Caliber Aircraft Rocket to train aircraft pilots to shoot aerial rockets that emerged during WWII, or the M303 Sub-Caliber insert for the M120 mortar that allows the mortar to use ammunition or the M49A1 sub-caliber device, which used 7.62×51mm NATO rifle rounds in the M67 recoilless rifle. These devices/weapons have been used for guns as large as the main guns of battleships. See also * Caliber conversion sleeve * Spotting rifle A spotting rifle or ranging gun is a small-calibre rifle used as a sighting device for artillery. The ballistics of the spotting rifle are matched to those of the artillery piece, so that if a shot f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5-Inch Forward Firing Aircraft Rocket
The 5-inch Forward Firing Aircraft Rocket or FFAR was an American rocket developed during World War II for attack from airplanes against ground and ship targets. Operational history The first FFARs were developed by the U.S. Navy and introduced in June 1943. They had a 3.5-inch diameter and a non-explosive warhead, since they were used as an aircraft-launched ASW (Anti-Submarine Warfare) rocket and worked by puncturing the hull. It was accurate enough for use against surface ships and land targets, but these missions required an explosive warhead.Parsch 2004 A 5-inch anti-aircraft shell was attached to the 3.5-inch rocket motor, creating the 5-Inch FFAR, which entered service in December 1943. Performance was limited because of the increased weight, limiting speed to 780 km/h (485 mph).Parsch 2006 The High Velocity Aircraft Rocket, or HVAR, was developed to fix this flaw. The FFAR was used by the Douglas SBD Dauntless (dive bomber), the Grumman TBF Avenger (torpedo b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bureau Of Ordnance
The Bureau of Ordnance (BuOrd) was a United States Navy organization, which was responsible for the procurement, storage, and deployment of all naval weapons, between the years 1862 and 1959. History Congress established the Bureau in the Department of the Navy by an act of July 5, 1862 (12 Stat. 510), which transferred the hydrographic functions of the Navy's Bureau of Ordnance and Hydrography (1842–1862) to the newly established Bureau of Navigation. During the early 20th century, BuOrd became involved in the development of aerial weapons. This often led to friction with the Bureau of Aeronautics (BuAer), which had responsibility for the development of Naval aircraft. BuAer's work on "pilotless aircraft," or drones, conflicted with BuOrd's development of guided missiles. After World War II, the Navy examined ways to improve coordination between the two bureaus; ultimately, the decision was made to merge the two organizations into a new bureau, to be known as the Bureau of ...

National Defense Research Committee
The National Defense Research Committee (NDRC) was an organization created "to coordinate, supervise, and conduct scientific research on the problems underlying the development, production, and use of mechanisms and devices of warfare" in the United States from June 27, 1940, until June 28, 1941. Most of its work was done with the strictest secrecy, and it began research of what would become some of the most important technology during World War II, including radar and the atomic bomb. It was superseded by the Office of Scientific Research and Development in 1941, and reduced to merely an advisory organization until it was eventually terminated during 1947. Organization The NDRC was created by an order of President Franklin Delano Roosevelt on June 27, 1940. It was part of the Council of National Defense, which had been created during 1916 to coordinate industry and resources for national security purposes. Vannevar Bush, the director of the Carnegie Institution, had pressed for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCAR Tiny
A scar (or scar tissue) is an area of fibrous tissue that replaces normal skin after an injury. Scars result from the biological process of wound repair in the skin, as well as in other organs, and tissues of the body. Thus, scarring is a natural part of the healing process. With the exception of very minor lesions, every wound (e.g., after accident, disease, or surgery) results in some degree of scarring. An exception to this are animals with complete regeneration, which regrow tissue without scar formation. Scar tissue is composed of the same protein (collagen) as the tissue that it replaces, but the fiber composition of the protein is different; instead of a random basketweave formation of the collagen fibers found in normal tissue, in fibrosis the collagen cross-links and forms a pronounced alignment in a single direction. This collagen scar tissue alignment is usually of inferior functional quality to the normal collagen randomised alignment. For example, scars in the s ...

High Velocity Aircraft Rocket
The High Velocity Aircraft Rocket, or HVAR, also known by the nickname Holy Moses, was an American unguided rocket developed during World War II to attack targets on the ground from aircraft. It saw extensive use during both World War II and the Korean War. Design and development The HVAR was designed by engineers at Caltech during World War II as an improvement on the 5-Inch Forward Firing Aircraft Rocket (FFAR), which had a diameter warhead but an underpowered diameter rocket motor. The desire for improved accuracy from the flatter trajectory of a faster rocket spurred the rapid development. HVAR had a constant 5-inch diameter for both warhead and rocket motor, increasing propellant from of Ballistite. U.S. Ballistite propellant had a sea level specific impulse of over , compared with about for the British Cordite, German WASAG and Soviet PTP propellants. Hercules Powder Company was the principal U.S. supplier of high performance extruded Ballistite propellants: 51.5% nitr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bombing Range
A bombing range usually refers to a remote military aerial bombing and gunnery training range used by combat aircraft to attack ground targets (air-to-ground bombing), or a remote area reserved for researching, developing, testing and evaluating new weapons and ammunition. Bombing ranges are used for precision targeting of high-explosive aerial bombs, precision-guided munitions and other aircraft ordnance, as opposed to a field firing range used by infantry and tanks. Various non-explosive inert "practice bombs" are also extensively used for precision aerial targeting bombing practice—to simulate various explosive aerial bomb types and minimise damage and environmental impact to bombing ranges. United Kingdom The Defence Training Estate of the UK Ministry of Defence currently runs five Air Weapons Ranges for military operational training: RAF Holbeach and RAF Donna Nook in Lincolnshire (England), RAF Pembrey in Carmarthenshire (Wales), RAF Tain in Rossshire and Cape Wra ...
