77-594: The Terrex Infantry Carrier Vehicle ( ICV ) is an armoured fighting vehicle (AFV) developed by ST Engineering of Singapore and Timoney Technology of Ireland, and produced by ST Engineering Land Systems (a corporate subsidiary of ST Engineering) for the Singapore Army as well as by Turkish auto-maker Otokar (manufacturing it under a license) as the Yavuz (AV-82) for the Turkish military. The Terrex's mass
154-433: A diesel engine ; modern technology, including the use of turbo-charging , helps to overcome the lower power-to-weight ratio of diesel engines compared to petrol. Gas turbine (turboshaft) engines offer a very high power-to-weight ratio and were starting to find favour in the late 20th century – however, they offer very poor fuel consumption and as such some armies are switching from gas turbines back to diesel engines (i.e.
231-447: A main battle tank will normally be designed to take hits from other tank guns and anti-tank missiles , whilst light reconnaissance vehicles are often only armoured "just in case". Whilst heavier armour provides better protection, it makes vehicles less mobile (for a given engine power), limits its air-transportability, increases cost, uses more fuel and may limit the places it can go – for example, many bridges may be unable to support
308-494: A turret or cupola. The greater the recoil of the weapon on an AFV, the larger the turret ring needs to be. A larger turret ring necessitates a larger vehicle. To avoid listing to the side, turrets on amphibious vehicles are usually located at the centre of the vehicle. Grenade launchers provide a versatile launch platform for a plethora of munitions including, smoke , phosphorus, tear gas , illumination, anti-personnel, infrared and radar-jamming rounds. Turret stabilization
385-454: A 105 mm cannon. This armored vehicle is also available in various turret-mounted armament configurations, but number of personnel carried is reduced. The Terrex can be airlifted by a C-130 Hercules or similar cargo aircraft. By mid-2004, one prototype and one pre-production model had been built and both were evaluated throughout Asia and Europe, where the vehicle was offered for a number of emerging wheeled armoured vehicle requirements. This
462-744: A British Army engineer. They were very popular with smaller countries. Some saw some combat (with limited success) in World War II. However, the vulnerability of their light armour eventually caused the concept to be abandoned. However, the German Army uses a modern design of air-transportable armoured weapons carriers, the Wiesel AWC , which resembles the concept of a tankette. The term "super-heavy tank" has been used to describe armoured fighting vehicles of extreme size, generally over 75 tonnes. Programs have been initiated on several occasions with
539-763: A Vickers QF-1 "Pom-Pom" gun of 40 mm. The Germans fielded the Sd.Kfz. 10/4 and 6/2, cargo halftracks mounting single 20 mm or 37 mm AA guns (respectively) by the start of the war. Rocket launchers such as the Soviet Katyusha originated in the late 1930s. The Wehrmacht fielded self-propelled rocket artillery in World War II – the Panzerwerfer and Wurfrahmen 40 equipped half-track armoured fighting vehicles. Many modern multiple rocket launchers are self propelled by either truck or tank chassis. The level of armour protection between AFVs varies greatly –

693-631: A government funded project to help develop a new generation of armoured personnel carriers for the Singapore Armed Forces. Singapore Technologies Kinetics, a subsidiary of Singapore Technologies Engineering, was chosen to design and manufacture the vehicle. The prototype Terrex AV81 armoured fighting vehicle was exhibited for the first time at DSEi 2001. The initial AV-81 design utilised conventional coil-spring shock absorbers but later variants introduced of hydro-pneumatic struts with real-time damping control. An electric-hybrid drive system
770-435: A highly mobile and protected fighting unit has been around for centuries; from Hannibal 's war elephants to Leonardo 's contraptions , military strategists endeavoured to maximize the mobility and survivability of their soldiers. Armoured fighting vehicles were not possible until internal combustion engines of sufficient power became available at the start of the 20th century. Modern armoured fighting vehicles represent
847-665: A more advanced driveline and hydro-pneumatic suspension system, and a number of changes from the AV81 including a flat underbody instead of a V-shaped hull, and revised rear suspension. In August 2012, the U.S. Marine Corps awarded SAIC a developmental contract for the Terrex for the Marine Personnel Carrier program. On 18 July 2013, SAIC , along with ST Engineering Land Systems and Armatec Survivability Corporation, successfully completed two weeks of evaluations of

In its baseline configuration, the AV-81 Terrex is fully amphibious : two water jets mounted on either side at the back of the hull propel the vehicle through water at 10 km/h. The following known variants are in service: On 23 November 2016, nine Terrex vehicles from
1001-467: A tank being first deployed as a medium tank, but in later years relegated to light tank roles. Tanks were also classified by roles that were independent of size, such as cavalry tank , cruiser tank , fast tank , infantry tank , "assault" tank, or "breakthrough" tank. Military theorists initially tended to assign tanks to traditional military infantry, cavalry, and artillery roles, but later developed more specialized roles unique to tanks. In modern use,
1078-414: A tank chassis. During World War II, most major military powers developed self-propelled artillery vehicles. These had guns mounted on a tracked chassis (often that of an obsolete or superseded tank) and provided an armoured superstructure to protect the gun and its crew. The first British design, "Bishop" , carried the 25 pdr gun-howitzer in an extemporised mounting on a tank chassis that severely limited
1155-450: A very large movable siege tower, the helepolis , as early as 340 BC, and Greek forces used such structures in the Siege of Rhodes (305 BC). The idea of a protected fighting vehicle has been known since antiquity. Frequently cited is Leonardo da Vinci 's 15th-century sketch of a mobile, protected gun-platform ; the drawings show a conical, wooden shelter with apertures for cannons around

Terrex AV81 APC variant is armed with a remotely controlled 40 mm automatic grenade launcher and coaxial 7.62 mm machine gun. Its modular top-deck system means it can be fitted with remotely-controlled 12.7 mm machine gun, 20–30 mm cannon or anti-tank guided missile to
1463-430: Is an important capability because it enables firing on the move and prevents crew fatigue. Modern AFVs have primarily used either petrol (gasoline) or diesel piston engines. More recently, gas turbines have been used. Most early AFVs used petrol engines , as they offer a good power-to-weight ratio . However, they fell out of favour during World War II due to the flammability of the fuel. Most current AFVs are powered by

The Terrex completed all required surf transit and ocean swim maneuverability tests at its fully loaded combat weight. It demonstrated load capabilities through successful stowage of gear and supplies that Marines would require for three days of operations, with space available for additional equipment. The human factors evaluation demonstrated
2772-421: The Terrex is of modular design with various levels of armour protection and weapon systems being marketed up to a gross vehicle weight of 24,000 kg. Despite its size, the Terrex is air-portable by C-130s or other similar cargo aircraft. The Terrex's layout is conventional: the driver sits front left and the power pack is to the right. This leaves the rest of the vehicle clear for the troop compartment, which

The vehicle has a double hull with an external V-hull that improves mine blast survivability. Add-on armour provides further protection for troops. It is also capable of providing full NBC (nuclear, biological, chemical) protection in extreme operational conditions. The standard equipment includes
3388-484: The capacity of transport aircraft makes possible and practicable the transport of AFVs by air. Many armies are replacing some or all of their traditional heavy vehicles with lighter airmobile versions, often with wheels instead of tracks. The first modern AFVs were armed cars, dating back virtually to the invention of the motor car . The British inventor F. R. Simms designed and built the Motor Scout in 1898. It

Leonardo claimed: "I will build armoured wagons which will be safe and invulnerable to enemy attacks. There will be no obstacle which it cannot overcome." Modern replicas have demonstrated that the human crew would have been able to move it over only short distances. Hussite forces in Bohemia developed war wagons – medieval horse-drawn wagons that doubled as wagon forts – around 1420 during
3542-429: The eight wheels. The suspension can be upgraded to active suspension and the wheels upgraded to run-flat tires. Furthermore, it features a hybrid-electric drive that helps push the vehicle to 120 km/h on roads (~75 mph) and also features a "Silent Mode" with a running radius of 50 km using on-board Li-ion batteries. The Terrex s5 is intended to be modular to suit a variety of missions. Six variants have been published:

The next major advance was the Birch gun (1925), developed for the British motorised warfare experimental brigade (the Experimental Mechanized Force ). This mounted a field gun, capable of the usual artillery trajectories and even anti-aircraft use, on
3773-438: The frontal assault role. Though several configurations have been tried, particularly in the early experimental "golden days" of tank development, a standard, mature design configuration has since emerged to a generally accepted pattern. This features a main tank gun or artillery gun , mounted in a fully rotating turret atop a tracked automotive hull, with various additional secondary weapon systems throughout. Philosophically,
3850-690: The gun's performance. It was replaced by the more effective Sexton . The Germans built many lightly armoured self-propelled anti-tank guns using captured French equipment (for example Marder I ), their own obsolete light tank chassis ( Marder II ), or ex-Czech chassis ( Marder III ). These led to better-protected tank destroyers, built on a medium-tank chassis such as the Jagdpanzer IV or the Jagdpanther . The Self-propelled anti-aircraft weapon debuted in WWI. The German 88 mm anti-aircraft gun
3927-400: The heavy tank has fallen out of favour, being supplanted by more heavily armed and armoured descendant of the medium tanks – the universal main battle tank . The light tank has, in many armies, lost favour to cheaper, faster, lighter armoured cars ; however, light tanks (or similar vehicles with other names) are still in service with a number of forces as reconnaissance vehicles , most notably

#17327929465004004-498: The individual vehicle too, depending on the role of the vehicle and the likely direction of attack. For example, a main battle tank will usually have the heaviest armour on the hull front and the turret, lighter armour on the sides of the hull and the thinnest armour on the top and bottom of the tank. Other vehicles – such as the MRAP family – may be primarily armoured against the threat from IEDs and so will have heavy, sloped armour on

On February 6, 2020, SAIC announced its acquisition of Unisys US Federal,
4158-515: The intense heat and noxious atmosphere. In 1917, Lieutenant G. J. Rackham was ordered to design an armoured vehicle that could fight and carry troops or supplies. The Mark IX tank was built by Armstrong, Whitworth & Co. , although just three vehicles had been finished at the time of the Armistice in November 1918, and only 34 were built in total. Different tank classifications emerged in
4235-792: The interwar period. The tankette was conceived as a mobile, two-man model, mainly intended for reconnaissance. In 1925, Sir John Carden and Vivian Loyd produced the first such design to be adopted – the Carden Loyd tankette . Tankettes saw use in the Royal Italian Army during the Italian invasion of Ethiopia (1935–1936), the Spanish Civil War (1936–1939), and almost everywhere Italian soldiers fought during World War II . The Imperial Japanese Army used tankettes for jungle warfare . The British Gun Carrier Mark I ,
4312-483: The mid-1920s as a reconnaissance vehicle and a mobile machine gun position They were one or two-man vehicles armed with a machine gun. Colloquially it may also simply mean a "small tank". Tankettes were designed and built by several nations between the 1920s and 1940s following the British Carden Loyd tankette which was a successful implementation of "one man tank" ideas from Giffard Le Quesne Martel ,
4389-515: The muddy, pocked terrain and slit trenches of the Battle of the Somme . The tank eventually proved highly successful and, as technology improved, it became a weapon that could cross large distances at much higher speeds than supporting infantry and artillery . The need to provide the units that would fight alongside the tank led to the development of a wide range of specialised AFVs, especially during
4466-484: The opposing force who can often hear and even feel their arrival. Tanks were classified either by size or by role. Classification by relative size was common, as this also tended to influence the tanks' role. Over time, tanks tended to be designed with heavier armour and weapons, increasing the weight of all tanks, so these classifications are relative to the average for the nation's tanks for any given period. An older tank design might be reclassified over time, such as
4543-527: The realization of an ancient concept – that of providing troops with mobile protection and firepower. Armies have deployed war machines and cavalries with rudimentary armour in battle for millennia. Use of these animals and engineering designs sought to achieve a balance between the conflicting paradoxical needs of mobility, firepower and protection. Siege engines , such as battering rams and siege towers , would often be armoured in order to protect their crews from enemy action. Polyidus of Thessaly developed

SECTION 60
#17327929465004774-439: The tank is, by its very nature, an offensive weapon. Being a protective encasement with at least one gun position, it is essentially a pillbox or small fortress (though these are static fortifications of a purely defensive nature) that can move toward the enemy – hence its offensive utility. Psychologically, the tank is a force multiplier that has a positive morale effect on the infantry it accompanies. It also instills fear in

5082-475: The weight of a main battle tank. A trend toward composite armour is taking the place of steel – composites are stronger for a given weight, allowing the tank to be lighter for the same protection as steel armour, or better protected for the same weight. Armour is being supplemented with active protection systems on a number of vehicles, allowing the AFV to protect itself from incoming projectiles. The level of protection also usually varies considerably throughout
5159-408: Was also developed. Designed with a modular protection system it is one of the latest and most advanced APCs with an all round protection against 7.62 mm NATO rounds and artillery shell splinters, front arc withstands 12.7 mm armor piercing-rounds at the most basic armor package. Ceramic-composite armor package are available for a higher level of protection. Maximum level of all-round protection

Wells's literary vision
5390-408: Was equipped with several screens with obstacle avoidance, situational awareness sensor feeds, and other features. Although the Terrex is specialised in ground operations, it also meets the minimum requirements for safe sea operation. The Terrex has a V-over-V hull that creates a crush zone to reduce the impact of a blast on the floor; this creates a spacious interior. Footrests attached to seats across
5467-550: Was further influenced by the emerging United States' Interim Brigade Combat Team (IBCT) concept, which called for the need of wheeled armoured fighting vehicles (AFV) as opposed to tracked AFVs. The Singapore Armed Forces will acquire at least 135 Terrex ICVs to replace its V-200 armoured vehicles, with all active Infantry and Guards battalions to begin training to operate from the vehicle in February 2010. The Second Battalion, Singapore Infantry Regiment , recently acquired

The armament, consisting of two Maxim guns, was carried in two turrets with 360° traverse. Another early armoured car of the period was the French Charron, Girardot et Voigt 1902 , presented at the Salon de l'Automobile et du cycle in Brussels , on 8 March 1902. The vehicle
5621-808: Was put on hold in June 2013, restarted in February 2014, and then restructured as Phase 1 of the Amphibious Combat Vehicle (ACV) program, which includes the previous MPC competitor entries. The Terrex 2 was publicly unveiled in September 2015 at the DSEI 2015 convention. On 24 November 2015, the Marines selected the SAIC Terrex, along with the BAE Systems / Iveco SuperAV , to move on to the engineering and manufacturing development phase of
5698-645: Was realized in 1916, when, amidst the pyrrhic standstill of the Great War , the British Landship Committee deployed revolutionary armoured vehicles to break the stalemate. The tank was envisioned as an armoured machine that could cross ground under fire from machine guns and reply with its own mounted machine guns and naval artillery . These first British tanks of World War I moved on caterpillar tracks that had substantially lower ground pressure than wheeled vehicles, enabling them to pass
5775-582: Was the first armed, petrol-engine powered vehicle ever built. It consisted of a De Dion-Bouton quadracycle with a Maxim machine gun mounted on the front bar. An iron shield offered some protection for the driver from the front, but it lacked all-around protective armour. The armoured car was the first modern fully armoured fighting vehicle. The first of these was the Simms's Motor War Car , also designed by Simms and built by Vickers, Sons & Maxim in 1899. The vehicle had Vickers armour 6 mm thick and
5852-507: Was to suppress enemy fire, crush obstacles such as barbed-wire entanglements, and protect the infantry on their advance into and through enemy lines by giving mobile overwatch and cover . The French Renault FT was the first iteration of this concept. The British and French retained the concept between the wars and into the Second World War era. Because infantry tanks did not need to be fast, they could carry heavy armour. One of
5929-615: Was truck-mounted and used to great effect against British tanks, and the British QF 3-inch 20 cwt was mounted on trucks for use on the Western Front . Although the Birch gun was a general purpose artillery piece on an armoured tracked chassis, it was capable of elevation for anti-aircraft use. Vickers Armstrong developed one of the first SPAAGs based on the chassis of the Mk.E 6-ton light tank/ Dragon Medium Mark IV tractor , mounting
