Katyusha multiple rocket launchers (Russian: Катюша) are a type of rocket artillery first built and fielded by the Soviet Union in World War II. Compared to other artillery, these multiple rocket launchers deliver a devastating amount of explosives to an area target quickly, but with lower accuracy and requiring a longer time to reload. They are fragile compared to artillery guns, but inexpensive and easy to produce. Katyushas of World War II, the first self-propelled artillery mass-produced by the Soviet Union,[1] were usually mounted on trucks. This mobility gave Katyushas (and other self-propelled artillery) another advantage: being able to deliver a large blow all at once, and then move before being located and attacked with counter-battery fire.

Katyusha weapons of World War II included the BM-13 launcher, light BM-8, and heavy BM-31. Today, the nickname is also applied to newer truck-mounted Soviet multiple rocket launchers—notably the common BM-21—and derivatives.

The nickname

Initially, the secrecy kept their military designation from being known by the soldiers who operated them. They were called by code names such as Kostikov Guns (after the head of the RNII), and finally classed as Guards Mortars.[2] The name BM-13 was only allowed into secret documents in 1942, and remained classified until after the war.[3]

Because they were marked with the letter K, for Voronezh Komintern Factory,[3] Red Army troops adopted a nickname from Mikhail Isakovsky’s popular wartime song, Katyusha, about a girl longing for her absent beloved, who is away performing military service.[4] Katyusha is the Russian equivalent of Katie, an endearing diminutive form of the name Katherine: Yekaterina →Katya →Katyusha.

German troops coined the sobriquet Stalin’s organ (German: Stalinorgel), after Soviet leader Joseph Stalin for its visual resemblance to a church musical organ and alluding to the sound of the weapon’s rockets. They are known by the same name in Sweden. [4]

The heavy BM-31 launcher was also referred to as Andryusha (Андрюша, “Andrew”, endearing diminutive).[5]
Katyushas of World War II

Katyusha rocket launchers were mounted on many platforms during World War II, including on trucks, artillery tractors, tanks, and armoured trains, as well as on naval and riverine vessels as assault support weapons.

The design was relatively simple, consisting of racks of parallel rails on which rockets were mounted, with a folding frame to raise the rails to launch position. Each truck had between 14 and 48 launchers. The 132-mm diameter M-13 rocket of the BM-13 system was 180 centimetres (70.9 in) long, 13.2 centimetres (5.2 in) in diameter and weighed 42 kilograms (92 lb). Initially, the caliber was 130 mm, but the caliber was changed (first the designation, and then the actual size), to avoid confusing them with regular artillery shells[3]. It was propelled by a solid nitrocellulose-based propellant of tubular shape, arranged in a steel-case rocket engine with a single central nozzle at the bottom end. The rocket was stabilised by cruciform fins of pressed sheet steel. The warhead, either fragmentation, high-explosive or shaped-charge, weighed around 22 kg (48 lb). The range of the rockets was about 5.4 kilometres (3.4 mi). Later, 82-mm diameter M-8 and 310-mm diameter M-31 rockets were also developed.

The weapon is less accurate than conventional artillery guns, but is extremely effective in saturation bombardment, and was particularly feared by German soldiers. A battery of four BM-13 launchers could fire a salvo in 7–10 seconds that delivered 4.35 tons of high explosives over a four-hectare (10 acres) impact zone.[2] With an efficient crew, the launchers could redeploy to a new location immediately after firing, denying the enemy the opportunity for counterbattery fire. Katyusha batteries were often massed in very large numbers to create a shock effect on enemy forces. The weapon’s disadvantage was the long time it took to reload a launcher, in contrast to conventional guns which could sustain a continuous low rate of fire.

The sound of the rocket launching also was unique in that the constant "woosh" sound that came from the firing of the rockets could be used for psychological warfare. The rocket’s devastating destruction also helped to lower the morale of the German army.

Combat history

The multiple rocket launchers were top secret in the beginning of World War II. A special unit of the NKVD secret police was raised to operate them.[2] On July 7, 1941, an experimental artillery battery of seven launchers was first used in battle at Orsha in Belarus, under the command of Captain Ivan Flyorov, destroying a station with several supply trains, and causing massive German Army casualties. Following the success, the Red Army organized new Guards Mortar batteries for the support of infantry divisions. A battery’s complement was standardized at four launchers. They remained under NKVD control until German Nebelwerfer rocket launchers became common later in the war.[6]

On August 8, 1941, Stalin ordered the formation of eight Special Guards Mortar regiments under the direct control of the General Headquarters Reserve (Stavka-VGK). Each regiment comprised three battalions of three batteries, totalling 36 BM-13 or BM-8 launchers. Independent Guards Mortar battalions were also formed, comprising 36 launchers in three batteries of twelve. By the end of 1941, there were eight regiments, 35 independent battalions, and two independent batteries in service, holding a total of 554 launchers.[11]

In June 1942 Heavy Guards Mortar battalions were formed around the new M-30 static rocket launch frames, consisting of 96 launchers in three batteries. In July, a battalion of BM-13s was added to the establishment of a tank corps.[12] In 1944, the BM-31 was used in Motorized Heavy Guards Mortar battalions of 48 launchers. In 1943, Guards Mortar brigades, and later divisions, were formed equipped with static launchers.[11]

By the end of 1942, 57 regiments were in service—together with the smaller independent battalions, this was the equivalent of 216 batteries: 21% BM-8 light launchers, 56% BM-13, and 23% M-30 heavy launchers. By the end of the war, the equivalent of 518 batteries were in service.[11]
[edit] Katyushas since World War II
Russian forces use BM-27 rocket launchers during the Second Chechen War

The success and economy of multiple rocket launchers (MRL) have led them to continue to be developed. During the Cold War, the Soviet Union fielded several models of Katyushas, notably the BM-21 launchers fitting the stereotypical Katyusha mould, and the larger BM-27. Advances in artillery munitions have been applied to some Katyusha-type multiple launch rocket systems, including bomblet submunitions, remotely-deployed land mines, and chemical warheads.

With the breakup of the Soviet Union, Russia inherited most of its military arsenal including the Katyusha rockets. In recent history, they have been used by Russian forces during the First and Second Chechen Wars and by Armenian and Azerbaijani forces during the Nagorno-Karabakh War. Georgian government forces are reported to have used BM-21 or similar rocket artillery in fighting in the 2008 South Ossetia war.[13]

Katyushas were exported to Afghanistan, Angola, Czechoslovakia, Egypt, East Germany, Hungary, Iran, Iraq, North Korea, Poland, Syria, and Vietnam. They were also built in Czechoslovakia[14], People’s Republic of China, North Korea, and Iran.[citation needed]

Katyushas also saw action in the Korean War, used by the Chinese People’s Volunteer Army against the South and United Nations forces. Soviet BM-13s were known to have been imported to China before the Sino-Soviet split and were operational in the People’s Liberation Army.

Israel captured BM-24 MRLs during the Six-Day War (1967), used them in two battalions during the Yom Kippur War (1973) and the 1982 Lebanon War, and later developed the MAR-240 launcher for the same rockets, based on a Sherman tank chassis. During the 2006 Lebanon War, Hezbollah fired between 3,970 and 4,228 rockets, from light truck-mounts and single-rail man-portable launchers. About 95% of these were 122 mm (4.8 in) Syrian-manufactured Katyusha artillery rockets, which carried warheads up to 30 kg (66 lb) and had a range of up to 30 km (19 mi).[15][16].[15][17][18] Hamas has launched 122-mm “Grad-type Katyusha” rockets from the Gaza Strip against several cities in Israel,[19] although they are not reported to have truck-mounted launchers.

Katyushas were also allegedly used by the Rwandan Patriotic Front during its 1990 invasion of Rwanda, through the 1994 genocide. They were effective in battle, but translated into much anti-Tutsi sentiment in the local media.[20]

It was reported that BM-21 launchers were used against American forces during 2003 invasion of Iraq. They have also been used in the Afghanistan and Iraq insurgencies. In Iraq, according to Associated Press and Agence France-Presse reports, Katyusha rockets were fired at the Green Zone late March 2008.[21][22]

NYC – Metropolitan Museum of Art: Astor Court – Cold Spring Pavilion

Image by wallyg
Historically, the finest scholars’ gardens of China were in Suzhou (soochow), a serene city inland from Shanghai. The design of the Astor Court is based on a courtyard in the Garden of the Master of the Fishing Nets (Wangshi Yuan) in Suzhou. Like its model, this court has three typical garden structures: a covered walkway, a small reception hall, and a half-pavilion along the west wall. Cold Spring Pavilion, identified by a tile plaque set in the wall, takes its name from the nearby pool. The exuberant upsweep of the roof corners is characteristic of Chinese architecture in the south.

Gray terracotta was a popular building material in Chinese gardens. In this court, the bricks are arranged in alternating sets of four; the large suqare floor tiles the doorframes, the low balustrades, and the trim along the tops of the walls are all low-fired unglazed ceramic specially produced for the Astor Court at an eighteenth-century imperial kiln near Suzhou. The granite slabs and the wood elements were also crafted in China ccording to traditional techniques. The components were installed by a team of twenty-seven Chinese engineers and craftsmen who worked at the Museum from January through May 1980.

The Ming’s Scholar’s retreat, a garden court and reception hall, was the concept of Brooke Russell Astor and became a reality because of her steadfast and generous support.

The Metropolitan Museum of Art‘s permanent collection contains more than two million works of art from around the world. It opened its doors on February 20, 1872, housed in a building located at 681 Fifth Avenue in New York City. Under their guidance of John Taylor Johnston and George Palmer Putnam, the Met’s holdings, initially consisting of a Roman stone sarcophagus and 174 mostly European paintings, quickly outgrew the available space. In 1873, occasioned by the Met’s purchase of the Cesnola Collection of Cypriot antiquities, the museum decamped from Fifth Avenue and took up residence at the Douglas Mansion on West 14th Street. However, these new accommodations were temporary; after negotiations with the city of New York, the Met acquired land on the east side of Central Park, where it built its permanent home, a red-brick Gothic Revival stone "mausoleum" designed by American architects Calvert Vaux and Jacob Wrey Mold. As of 2006, the Met measures almost a quarter mile long and occupies more than two million square feet, more than 20 times the size of the original 1880 building.

In 2007, the Metropolitan Museum of Art was ranked #17 on the AIA 150 America’s Favorite Architecture list.

The Metropolitan Museum of Art was designated a landmark by the New York City Landmarks Preservation Commission in 1967. The interior was designated in 1977.
