Query: What types of helicopters are there?
Not all militaries are able to operate a full range of transport helicopters, so the medium transport type is probably the most useful compromise and probably the most common specialist transport type. Medium transport helicopters are generally capable of moving up to a platoon of infantry and are capable of being able to transport towed artillery or light vehicles either internally or as underslung roles. Unlike the assault helicopter they are usually not expected to land directly in a contested landing zone, but are used to reinforce and resupply landing zones taken by the initial assault wave. Examples include the unarmed versions of the Mil Mi-8, Super Puma, and CH-46 Sea Knight.
There are approximately 30 non-flying Mosquitos around the world with four airworthy examples, two in the United States, one in Canada and one in New Zealand. The largest collection of Mosquitos is at the de Havilland Aircraft Heritage Centre in the United Kingdom, which owns three aircraft, including the first prototype, "W4050", the only initial prototype of a Second World War British aircraft design still in existence in the 21st century.
Fighter-bombers became increasingly important in the 1950s and 1960s, as new jet engines dramatically improved the power of even the smallest fighter designs. Many aircraft initially designed as fighters or interceptors found themselves in the fighter-bomber role at some point in their career. Notable among these is the Lockheed F-104 Starfighter, first designed as a high-performance day fighter and then adapted to the nuclear strike role for European use. Another such aircraft was the Indian HAL HF-24 Marut. It was used during the Indo-Pak war of 1971, and only three aircraft were lost to ground fire. One aerial kill recorded by Marut flown by Squadron Leader K.K. Bakshi of 220 Squadron shot down a PAF F-86 Sabre on 7 Dec 71 (Flag Officer Hamid Khwaja of 15 Squadron PAF). Other U.S. examples include the North American F-100 Super Sabre and (perhaps most famously) the McDonnell Douglas F-4 Phantom II, each of which were widely used during the Vietnam War.
The Republic P-47 Thunderbolt was a World War II era fighter aircraft produced by the United States from 1941 through 1945. Its primary armament was eight .50-caliber machine guns and in the fighter-bomber ground-attack role it could carry five-inch rockets or a bomb load of 2,500 pounds (1,103 kg). When fully loaded the P-47 weighed up to eight tons (tonnes) making it one of the heaviest fighters of the war. The P-47 was designed around the powerful Pratt & Whitney R-2800 Double Wasp engine which was also used by two U.S. Navy fighters, the Grumman F6F Hellcat and the Vought F4U Corsair. The Thunderbolt was effective as a short-to-medium range escort fighter in high-altitude air-to-air combat and ground attack in both the World War II European and Pacific theaters.
This is the mechanical rate of fire, or how fast the weapon "cycles" (loads, locks, fires, unlocks, ejects). Measurement of the cyclic rate assumes that the weapon is being operated as fast as possible and does not consider operator tasks (magazine changes, aiming, etc.). When the trigger is pulled, the rate at which rounds are fired is the cyclic rate. Typical cyclic rates of fire are 600–900 RPM for assault rifles, 1,000-1,100 RPM in some cases, 900-1,200 RPM for submachine guns and machine pistols, and 600-1,500 RPM for machine guns. M134 Miniguns mounted on attack helicopters and other combat vehicles can achieve rates of fire of over 100 rounds per second (6,000 RPM). Cyclic rate of fire is the only rate that can be determined precisely.
In the Korean War, Mustangs from No. 77 Squadron (77 Sqn), stationed in Japan with the British Commonwealth Occupation Force, were among the first United Nations aircraft to be deployed, in ground support, combat air patrol, and escort missions. When the UN planes were confronted by MiG-15 jet fighters, 77 Sqn acquired Gloster Meteors, which enabled some success against the Soviet pilots flying for North Korea. However, the MiGs were superior aircraft and the Meteors were relegated to ground support missions, as the North Koreans gained experience. The air force also operated transport aircraft during the conflict.
A fast craft is a vessel capable of speeds over 30 knots. HSICs (High Speed Interceptor Craft) however, trump fast craft with speeds of over 50 knots. HSICs are usually either custom or law enforcement craft. Law enforcement use these extremely fast boats to catch criminals such as smugglers or drug traffickers who use fast craft as well. The military have started to use HSICs to stop international threats such as pirates, militias, terrorists and weapons traffickers. Originally HSICs were not meant to carry large weapons. Now that the military is using them, they are being built with heavy machine guns. The boats have to be fitted with robust weight control and at the same time have heavy amour. HSICs must do without propellers to account for cavitation and vibrations. Instead HSICs use surface drivers or water jets.
Ground Attack Aviation or Fighter-Bomber Aviation (Lovačko-Bombarderska Aviacija) was in the second plan of JRV. All attack aircraft were home-made. The new aircraft like J-22 Orao attack aircraft and G-4 Super Galeb light-attack trainer were replacing older J-21 Jastreb light-attack and G-2 Galeb light-attack trainer aircraft. The First Corps of AF and AD had two fighter-bomber squadrons and one reconnaissance squadron equipped with ground attack reconnaissance aircraft. 252nd from Batajnica Airbase was under direct command of its Corps of AF and AD (unlike other squadrons which were under the command of their Regiments/Brigades). It was equipped with older J-21 Jastreb light attack aircraft and G-2 Galeb trainer/attack aircraft, Utva-66 utility aircraft and new G-4 Super Galebs. Under command of the 97th Aviation Brigade (which was in 1st Corps of AF and AD) there was one fighter-bomber squadron, 240th, equipped with Jastrebs and one reconnaissance squadron, 353.IAE, equipped with IJ-22 Orao reconnaissance-attack aircraft. The Third Corps of AF and AD had two major fighter-bomber aviation units, 98th Aviation Brigade and 127th Fighter-Bomber Aviation Regiment. 98th Aviation Brigade from Skopski Petrovac in Macedonia had three squadrons, two fighter-bomber squadron and one reconnaissance squadron. Fighter-bomber squadrons were 241st equipped with J-22 Orao attack aircraft, 247th with Jastrebs and 354th IAE was equipped with IJ-21 Jastreb reconnaissance aircraft. 127th Fighter-Bomber Aviation Regiment at Golubovci Airbase comprised two fighter-bomber squadrons, 239th equipped with G-4 Super Galebs and 242nd equipped with Jastrebs and J-22 Orao aircraft. The Fifth Corps of AF and AD had most fighter-bomber aviation units, one Aviation Brigade and two Fighter-Bomber Aviation Regiments. 82nd Aviation Brigade, at Cerklje Airbase, Slovenia, had two fighter-bomber squadrons and one reconnaissance squadron. Two fighter-bomber squadrons were 237.LBAE equipped with J-21 and NJ-21 Jastrebs, and 238th equipped with J-22 and NJ-22 Orao aircraft. Reconnaissance squadron was 351st equipped with IJ-21 Jastreb and IJ-22 Orao reconnaissance-attack aircraft. 105th Fighter-Bomber Aviation Regiment at Zemunik-Zadar Airbase comprised two fighter-bomber aviation squadrons, 249th equipped with Super Galebs, 251st with Galebs and one aviation squadron, 333rd equipped with Utva 75 training aircraft, An-2 transport aircraft, Gazelle helicopters and Super Galebs. 185th Fighter-Bomber Aviation Regiment at Pula Airport has compos of one fighter-bomber squadron, 229th equipped with G-4 Super Galebs and one fighter squadron, 129th equipped with MiG-21 aircraft in versions MiG-21PFM, MiG-21US and MiG-21UM.
In April and May 1982, a squadron of mothballed British Hawker Hunter fighter-bombers departed for Chile, arriving on 22 May and allowing the Chilean Air Force to reform the No. 9 "Las Panteras Negras" Squadron. A further consignment of three frontier surveillance and shipping reconnaissance Canberras left for Chile in October. Some authors have speculated that Argentina might have won the war had the military felt able to employ the elite VIth and VIIIth Mountain Brigades, which remained sitting in the Andes guarding against possible Chilean incursions. Pinochet subsequently visited the UK on more than one occasion. Pinochet's controversial relationship with Thatcher led Labour Prime Minister Tony Blair to mock Thatcher's Conservatives as "the party of Pinochet" in 1999.
On the airfield quantity Hohentengen was the Dornier Do 335, one of the fastest fighter of World War II, tested.
The modern strategic bomber role appeared after strategic bombing was widely employed, and atomic bombs were first used in combat during World War II. Nuclear strike missions (i.e., delivering nuclear-armed missiles or bombs) can potentially be carried out by most modern fighter-bombers and strike fighters, even at intercontinental range, with the use of aerial refueling, so any nation possessing this combination of equipment and techniques theoretically has such capability. Primary delivery aircraft for a modern strategic bombing mission need not always necessarily be a heavy bomber type, and any modern aircraft capable of nuclear strikes at long range is equally able to carry out tactical missions with conventional weapons. An example is France's Mirage IV, a small strategic bomber replaced in service by the ASMP-equipped Mirage 2000N fighter-bomber and Rafale multirole fighter.
The list of cloud types groups the tropospheric types as "high" (cirrus, cirrocumulus, cirrostratus), "middle" (altocumulus, altostratus), "multi-level" (nimbostratus, cumulus, cumulonimbus), and "low" (stratocumulus, stratus) according to the altitude level or levels at which each cloud is normally found. Small cumulus are commonly grouped with the low clouds because they do not show significant vertical extent. Of the multi-level genus-types, those with the greatest convective activity are often grouped separately as "towering vertical". The genus types all have Latin names.
British long-range bomber planes such as the Short Stirling had been designed before 1939 for strategic flights and given a large armament, but their technology still suffered from numerous flaws. The smaller and shorter ranged Bristol Blenheim, the RAF's most-used bomber, was defended by only one hydraulically operated machine-gun turret, and whilst this appeared sufficient, it was soon revealed that the turret was a pathetic defence against squadrons of German fighter planes. American bomber planes such as the B-17 Flying Fortress had been built before the war as the only adequate long-range bombers in the world, designed to patrol the long American coastlines. Defended by as many as six machine-gun turrets providing 360° cover, the B-17s were still vulnerable without fighter protection even when used in large formations.
After 20 years and 5000 hours in fighter jets, Shul retired from the Air Force in 1990 and went on to pursue his writing and photographic interests. In addition to running his own photo studio in northern California, he has authored seven books on flying and flight photography. His first two books ("Sled Driver: Flying The World's Fastest Jet" and "The Untouchables") are about flying the SR-71 Blackbird and give the reader a first-hand account of being in the cockpit of the world's fastest jet. Shul's third and fourth books are about America's air demonstration teams, the Navy Blue Angels, in "Blue Angels: A Portrait of Gold", and the Air Force Thunderbirds, in "Summer Thunder" and contain aerial images which take the reader into the dynamic formations of these world-famous teams. In 1997, Shul released his fifth book, "Eagle Eyes : Action Photography from the Cutting Edge", which is a collection of his in-flight photos. He has also released special, revised editions of both "Sled Driver" and "The Untouchables".
A fighter-bomber is a fighter aircraft that has been modified, or used primarily, as a light bomber or attack aircraft. It differs from bomber and attack aircraft primarily in its origins, as a fighter that has been adapted into other roles, whereas bombers and attack aircraft are developed specifically for bombing and attack roles.
In the buildup to the Second World War, the United Kingdom had embarked on a programme to develop cannon-armed fighters. They acquired a licence to build the HS.404, which entered production as the Hispano Mk.I intended as aeroplane armament. Its first use was in the Westland Whirlwind of 1940, and later in the more powerful Bristol Beaufighter, providing the Royal Air Force with powerful cannon-armed interceptors. The experience of the Battle of Britain had shown the batteries of eight rifle-calibre machine guns to be inadequate and prompted the adoption of autocannon armament for the primary portion of Royal Air Force (RAF) fighters. The Beaufighter highlighted the need for a belt feed mechanism; as a night fighter the 60-round drums needed to be replaced in the dark by the Radar/Wireless Operator, often while the aircraft was manoeuvering to keep sight of its quarry. In addition, the early trial installations in the Hawker Hurricane and Supermarine Spitfire had shown a tendency for the gun to jam during combat manoeuvres, leading to some official doubt as to the suitability of cannon as the sole main armament. This led to the Air Ministry for a brief period specifying 12-machine gun armament for new fighters.
On 12 May 1968 airlifters in Vietnam as they were called upon to evacuate the camp at Kham Duc. Although two C-130s, one of which was from the 374th, were shot down and others were damaged, they managed to bring out about half of the camps defenders while US Army and USMC helicopters brought out the remainder who did not exfiltrate out on the ground. Lt. Col. Daryl D. Cole was awarded the prestigious MacKay Trophy for the most meritorious flight of the year for flying his badly damaged C-130A out of Kham Duc. Lt. Col. John Delmore's crew crash landed at Kham Duc but were quickly rescued by US Army personnel.
According to this account, eight Junkers Ju 88C-6 heavy fighters ("Zerstörer") from the 14th Staffel of the Luftwaffe's main maritime bomber wing, "Kampfgeschwader 40", took off from Bordeaux at 10:00 hrs local time to find and escort two U-boats; these aircraft belonged to the long-range fighter group known as "Gruppe V Kampfgeschwader 40". The names of four of the eight pilots are known: Staffelführer Oberleutnant (Oblt) Herbert Hintze, Leutnant Max Wittmer-Eigenbrot, Oblt Albrecht Bellstedt, and Oberfeldwebel (Ofw) Hans Rakow. The pilots claim that before setting out they were unaware of the presence of the Lisbon to Whitchurch flights. Due to bad weather, the search for the U-boats was called off and the fighters continued a general search. At 12:45 hrs, BOAC Flight 777 was spotted in P/Q 24W/1785 heading north. Approximately five minutes later, the Ju 88s attacked. Hintze retold his account for Goss as follows: "A 'grey silhouette' of a plane was spotted from 2,000–3,000 metres (6,600–9,800 ft) and no markings could be made out, but by the shape and construction of the plane it was obviously enemy." Bellstedt radioed: "Indians at 11 o'clock, AA (code for enemy aircraft ahead slightly to left, attack)." BOAC Flight 777 was attacked from above and below by the two Ju 88s assigned to a high position over the flight, and the port engine and wing caught fire. At this point flight leader Hintze, at the head of the remaining six Ju 88s, caught up to the DC-3 and recognised the aircraft as civilian, immediately calling off the attack, but the burning DC-3 was already severely damaged with the port engine out. Three parachutists exited the burning aircraft, but their chutes did not open as they were on fire. The aircraft then crashed into the ocean, where it floated briefly before sinking. There were no signs of survivors.
The Gloster Meteor was the first British jet fighter and the Allies' only jet aircraft to achieve combat operations during the Second World War. The Meteor's development was heavily reliant on its ground-breaking turbojet engines, pioneered by Sir Frank Whittle and his company, Power Jets Ltd. Development of the aircraft began in 1940, although work on the engines had been under way since 1936. The Meteor first flew in 1943 and commenced operations on 27 July 1944 with No. 616 Squadron RAF. The Meteor was not a sophisticated aircraft in its aerodynamics, but proved to be a successful combat fighter. Gloster's 1946 civil Meteor F.4 demonstrator "G-AIDC" was the first civilian-registered jet aircraft in the world.
After the Luftwaffe's specialist ground attack aircraft, the Junkers Ju 87, suffered heavy losses in attacks on Britain, it was decided to use modified Messerschmitt Bf 109s and Messerschmitt Bf 110 as fighter-bombers. The first unit equipped with these aircraft, "Erprobungsgruppe" 210, began conducting operations against shipping in the English Channel in the third week of July. The unit began operations against ground targets on 12 August, when aircraft from its three squadrons ("staffel") simultaneously attacked radar stations near Dover, Pevensey, Rye and Dunkirk. The unit continued fighter-bomber operations throughout July, but suffered heavy losses during raids on inland targets; casualties among the Bf 110s were particularly high, and it became clear that these large and relatively slow aircraft were not suited to the fighter-bomber role. Nevertheless, the Luftwaffe decided to expand its fighter bomber force, and an additional group equipped with modified Bf 109s became active in August. On 2 September Hermann Göring, the Commander-in-Chief of the Luftwaffe, directed that one squadron of each Bf 109 group was to be equipped with fighter-bombers, and that these aircraft were to be used to attack the British aircraft industry and other industrial facilities.
The name "Haflinger" comes from the village of Hafling, which today is in northern Italy. The breed is also called the Avelignese, from the Italian name for Hafling, which is "Avelengo" or previously "Aveligna". Haflingers are always chestnut in color and come in shades ranging from a light gold to a rich golden chestnut or liver hue. The mane and tail are white or flaxen. The height of the breed has increased since the end of World War II, when it stood an average of . The desired height today is between . Breeders are discouraged from breeding horses under the minimum size, but taller individuals may pass inspection if they otherwise meet requirements of the breed registry. The breed has a refined head and light poll. The neck is of medium length, the withers are pronounced, the shoulders sloping and the chest deep. The back is medium-long and muscular, the croup is long, slightly sloping and well-muscled. The legs are clean, with broad, flat knees and powerful hocks showing clear definition of tendons and ligaments. The Haflinger has rhythmic, ground-covering gaits. The walk is relaxed but energetic. The trot and canter are elastic, energetic, and athletic with a natural tendency to be light on the forehand and balanced. There is some knee action, and the canter has a very distinct motion forwards and upwards. One important consideration in breeding during the second half of the 20th century was temperament. A requirement for a quiet, kind nature has become part of official breed standards and is checked during official inspections. Some sources recognize two types of Haflinger, a shorter, heavier type used for draft work and a taller, lighter type used for pleasure riding, light driving and under-saddle competition. The Food and Agriculture Organization recognizes both an "Avelignese" and an "Avelignese Tradizionale" as existing in Italy, although, as of 2007, only 13 of the latter existed, including only one breeding stallion. However, all breed organizations recognize and register only one type.
Besides the ubiquitous helicopter, there are currently two types of VTOL aircraft in military service: craft using a tiltrotor, such as the Bell Boeing V-22 Osprey, and another using directed jet thrust, such as the Harrier family and new F-35B Lightning II Joint strike Fighter (JSF). In the civilian sector currently only helicopters are in general use (some other types of commercial VTOL aircraft have been proposed and are under development ). Generally speaking, VTOL aircraft capable of STOVL use it wherever possible, since it typically significantly increases takeoff weight, range or payload compared to pure VTOL.
In October 2011 the German Federal Ministry of Defence announced a reorganisation/reduction of the German Armed Forces. As a consequence, all helicopters of the type CH-53G were to be transferred to the Air Force. German Army Aviation Corps Medium Transport Helicopter Regiment 25 flying CH-53G, based at Laupheim Air Base, was disbanded on 31 December 2012 and re-established as new Helicopter Wing 64 on 1 January 2013. The other unit within the German Army flying CH-53G, Aviation Corps Medium Transport Regiment 15 based at Rheine Air Base, will be disbanded, a number of its helicopters eventually relocating to either Laupheim Air Base or Holzdorf Air Base. The remainder will be decommissioned. The wing's helicopters of the type Bell UH-1D and NH90 were transferred to the German Army. The tasks previously carried out by helicopters of Helicopter Wing 64, most importantly national SAR service and CSAR, were also transferred to the German Army. The restructured wing has a strength of approximately 1800 personnel, 1200 of which are stationed at Laupheim Air Base, the remaining 600 at Holzdorf Air Base.
The class carries one anti-submarine helicopter on a deck placed aft with a hangar provided for storage. Originally supplied with a Eurocopter AS 565 Panther, they were later replaced with the Westland Lynx. The SAMAHE 210 helicopter handling system is adaptable to different types of undercarriages on helicopters and had munitions trucks to position weapon loadouts to assist the arming of the helicopters.
While the United States Army Aviation Branch operates a few fixed-wing aircraft, it mainly operates several types of rotary-wing aircraft. These include the AH-64 Apache attack helicopter, the UH-60 Black Hawk utility tactical transport helicopter and the CH-47 Chinook heavy-lift transport helicopter. Restructuring plans call for reduction of 750 aircraft and from 7 to 4 types.
