Tunguska Explosion 30 July 1908

At 7:17 AM on the morning of June 30, 1908, a mysterious explosion occurred in the skies over Siberia. It was caused by the impact and breakup of a large meteorite, at an altitude roughly six kilometers in the atmosphere. Realistic pictures of the event are unavailable. However, Russian scientists collected eyewitness accounts of the event. I believe that we now know enough about large impacts to "decode" the subjective descriptions of the witnesses and create realistic views of this historic asteroid impact as seen from different distances.

Indian Army got dozens of Tunguska,100s of T90s & INSAS Fire

Russian video!! except indian soldiers shooting part!!Indian army has got dozens of tunguskas,T90s!! A sample firing clip!! Tunguska-M1 is a gun/missile system for low-level air defense. The system was designed by the KBP Instrument Design Bureau in Tula, Russia and is manufactured by the Ulyanovsk Mechanical Plant, Ulyanovsk, Russia. It can engage targets while stationary and on the move, using missiles for long-range targets and guns for close-in defense. It is designed for defense against both fixed-wing aircraft and helicopters and can also fire on ground targets. The Tunguska-M1 vehicle carries eight 9M311-M1 surface-to-air missiles. Range is from 15 to 6,000 meters for ground targets and 15 to 10,000 meters for air targets. The system has target acquisition radar and target tracking radar, optical sight, a digital computing system, tilt angle measuring system and navigation equipment. Radar detection range is 18 kilometers and tracking range is 16 kilometers

air defense ZSU-23 Shilka Tunguska

The Shilka ZSU-23-4 [ZSU = Zenitnaya Samokhodnaya Ustanovka - Anti-aircraft Self-Propelled Gun] is a Self-Propelled Anti-Aircraft Gun (SPAAG) featuring a prominent radar dish that can be folded down mounted on a modified PT-76 chassis. ZSU 23-4 Shilka, is capable of acquiring, tracking and engaging low-flying aircraft (as well as mobile ground targets while either in place or on the move). Employed in pairs 200 meters apart, 400 meters behind battalion leading elements, it is commonly used to surpress ATGM launch sites, such as TOW vehicles. The armament consists of four 23mm cannon with a maximum slant range of 3,000 meters. Ammunition is normally loaded with a ratio of three HE rounds to one AP round. Resupply vehicles carry an estimated additional 3,000 rounds for each of the four ZSUs in a typical battery. Recent (October 1997) information details ZSU-23-4 updates/modernization being offered by the Ukrainians that include: a new radar system replacing the GUN DISH radar, plus a sensor pod believed to include day/night camera, and a laser rangefinder; and mounted above radar/sensor pod is a layer of six fire-and-forget SAMs, believed to be Russian SA-18/GROUSE. The ZSU-23-4 is a fully integrated, self-propelled antiaircraft system with four liquid-cooled 23-mm automatic cannons mounted on the front of a large, flat, armored turret. The chassis has many components borrowed from other Soviet armored vehicles, and the suspension system resembles that of the PT-76 and ASU 85 (six road wheels and no track support rollers). The driver sits in the left front of the hull, and the rest of the crew (commander, gunner, and radar operator) are located in the turret. The GUN DISH fire control radar mounted on the rear of the turret can be folded down during travel. A number of different ZSU-23-4 models have been produced. These are primarily distinguishable externally by the types of stowage boxes on the turret and minor modifications in the mounting of the guns. CAPABILITIES: A platoon of four ZSU-23-4s is assigned, along with four SA-9/GASKIN SAM systems, to the antiaircraft battery of motorized rifle and tank regiments to cover the deadspace of the SA-6/GAINFUL in the division air defense umbrella. Two ZSU-23-4s usually will be in support of each of the two first-echelon battalions, each weapon normally separated by 200 meters, typically traveling 400 meters behind the battalion's leading elements. The ZSU-23-4 is not amphibious, but has a fording capability of just over one meter. During river assault operations, the ZSU-23-4s would be ferried to the far bank immediately after the leading companies. The ZSU-23-4 has the capability to both acquire and track low-flying aircraft targets, with an effective AA range of 2,500 meters. It also is capable of firing on the move because of its integrated radar/gun stabilization system. The high frequency operation of the GUN DISH radar emits a very narrow beam that provides for excellent aircraft tracking while being difficult to detect or evade. However, such a frequency also dictates a limited range, which can be compensated for by linking the system to other long-range acquisition radar in the area. The ZSU-23-4 also can be used against lightly armored ground vehicles. The four guns are water cooled and have a cyclic rate of fire of 800 to 1,000 rounds per minute each. However, the guns are normally fired in bursts (2-3 rounds per barrel) to reduce ammunition expenditure and prolong barrel life. Each ZSU-23-4 carries about 2,000 rounds onboard. Supply trucks, which follow the ZSUs at a distance of 1.5 to 2.5 km, carry an estimated additional 3,000 rounds for each of the four ZSUs. Electronic target acquisition, tracking, and ranging are automated, and an onboard computer determines superelevation and azimuth lead. Conventional optical sights also are available. Two types of ammunition normally are mixed at a ratio of three Frag-HE-T rounds per one API-T round. An HEI-T round also may be fired. TheZSU-23-4can be airlifted bytheAN-22 or II-76. The crew of the ZSU-23-4 is afforded a degree of protection by the thin armor (maximum thickness 9.4 mm in the hull, 8.9 in the turret). Collective NBC protection is provided by a radiation detection and warning system and an air filtration and overpressure system. LIMITATIONS: Heavy machine gun fire can penetrate the hull and turret. Tread and road wheels are vulnerable to artillery fire. HE fragmentation can penetrate the armor, destroy the radar dish, or rupture the liquid coolant sleeves of the 23-mm cannons. The system also is vulnerable to ECM.

Apocalypse Then - Tunguska Explosion

June 30 marks the 100th anniversary of a huge mid-air explosion that flattened hundreds of square miles of forests in Siberia. Recent computer simulations show it might have been a smaller near-earth object than previously theorized -- and thus the kind that hits Earth more frequently.
