MK44 Bushmaster Cannon

http://www.discoverychannel.co.uk/video ... er-cannon/

The Mk 44 is a medium caliber automatic cannon capable of being used in fighting platforms to include ground vehicle, naval and aircraft applications. This weapon can be converted to fire 40mm rounds with a change of barrels and minor changes to the feeder assembly. The conversion has been described as relatively simple by the manufacturer, for example being able to be performed by the crew on the ship on which the weapon is mounted.

One of the Mk 44 chain gun's intended applications is on the Marine Corps Expeditionary Fighting Vehicle (EFV), formerly known as the Advanced Attack Amphibious Vehicle (AAAV). The Expeditionary Fighting Vehicle's (EFV) Mk 46 Mod 0 Weapon Station incorporates the 30mm Mk 44 automatic gun, as well as, a 7.62mm coaxial machine gun. The Mk 46 Mod 0 Weapon Station as designed will carry 215 ready rounds of 30mm and 600 ready rounds of 7.62mm ammunition. The load out has been described as sufficient to complete the intended EFV mission. Since 1997, the EFV Program has been a leader in developing the Mk 44, which has been adopted by other DoD acquisition programs including the USN LPD-17 amphibious ship class and the USAF AC-130 Gunship programs.

The Mk 44 Cannon and Mk 46 Weapon Station nomenclature has been the source of some ambiguity and confusion in official publications, which have at times used the nomenclature interchangeably. This weapon should not be confused with the Mk 46 Mod 0 5.56mm Lightweight Machine Gun, a compact, belt-fed machine gun manufactured by FN Herstal of Belgium. It should also not be confused with the the 3,000 rounds-per-minute 7.62 mm GAU-17/A rotary barrel machine gun.

Developed by UK firm Amsafe, Tarian cloth is capable of repelling armor-piercing anti-tank warheads by creating a ‘cushion’ between the vehicle’s exterior and typical armor plating, thereby triggering the explosive early and dispersing the force of the blast across the existing armor.

Traditional slat or metal-bar protection has a similar effect and through it is relatively light in comparison to the primary armor-plating of a vehicle, still has a detrimental effect on mobility and load-capacity. Being 50% lighter than aluminum cage armor and 85% lighter than steel cage options, Tarian (Welsh for "shield") reduces the chance of overloading the vehicle and means that more equipment can be carried and further precautions taken to ensure the safety of the passengers.

Currently being favored over traditional protection on British combat vehicles, Amsafe approached the UK MOD with its design in 2005 and subsequent trials in Afghanistan have encouraged DARPA (Defense Advanced Research Projects Agency) to order thirty ‘test articles’ at a cost of $100,000.

DARPA is confident that the Dorset company’s research has the potential to solve a very real problem and with additional vehicle-based and static application on the table, Tarian’s modular, replaceable design could well become an essential ingredient in modern warfare.

Corps can move ahead with IAR testing

Protest from competitor dismissed
By Dan Lamothe - Staff writer
Posted : Wednesday Feb 24, 2010 16:49:26 EST
   
Congressional investigators have sided with the Marine Corps in a dispute over the service’s infantry automatic rifle program, calling the competition fair and clearing the way for the service to choose its preferred weapon.

Weapons maker FN Herstal protested the Corps’ Oct. 23 decision to eliminate the company from the competition on grounds that its IAR failed to meet requirements in testing, according to a Dec. 15 report by the Government Accountability Office obtained by Marine Corps Times. The Corps ultimately chose the IAR made by Heckler & Koch, spurning FN and Colt Defense, which competed two weapons for the contract.

The IAR competition is not considered complete, however, as the Corps intends to perform more tests on H&K’s weapon throughout the year ahead. H&K’s weapon was chosen in a “down-select,” meaning that while the Corps will continue assessing it, there are no guarantees H&K will supply the 4,100 IARs the Corps plans to buy.

All four 5.56mm weapons tested carry 30-round magazines and were viewed as possible replacements for many of the M249 squad automatic weapons the Corps has fielded since the 1980s. The preferred H&K model is a variant of the HK416 assault rifle, which uses a spring-buffered short-stroke gas-piston system and is the sole finalist that fires only from the closed-bolt position.

In its protest, FN claimed that during tests its weapon’s barrel “was infected by copper residue,” effectively skewing the results, according to the GAO. FN, maker of the SAW, also blamed the Corps for failing to properly tighten the pistol grips that fell off two of its three test models during extreme cold-weather trials conducted at minus-25 degrees.

The specifics of FN’s protest shifted throughout November and December as the company and the Corps sought to bolster their cases, the GAO said. FN “abandoned its initial protest argument that the [Corps] may not have performed required regular maintenance,” the GAO said. After reviewing additional documents provided by the Corps, the company protested on several other grounds, including that the Corps was mistaken in saying more than one FN pistol grip fell off and that the grips from other companies in the competition also fell off and were not similarly rejected.

“These arguments … constitute independent grounds of protest,” GAO acting general counsel Lynn Gibson wrote in the report. “Since the basis of protest stems from the protester’s review of the [Marine Corps] test report and other documents … we find the arguments raised in FN’s comments to be untimely.”

The GAO hasn’t said whether FN’s later complaints were legitimate or investigated. Company officials with FN and H&K did not respond to requests for comment. Capt. Geraldine Carey, a spokeswoman for Marine Corps Systems Command, said the Corps would not comment on FN’s protest.

The service has ordered 24 more H&K IARs to be tested in locations ranging from Panama to the Marine Corps Air Ground Combat Center and Marine Corps Mountain Warfare Training Center in California, Marine officials have said.

Eventually, the Corps plans reduce the number of SAWs in the service from about 10,000 to 8,000 as it rolls out the IAR. Each infantry company will retain six SAWs to employ as the tactical situations dictate, but the IAR will replace the SAW in many patrol situations, Marine officials have said.

Corps may field infantry auto-rifle this fall


   
The Marine Corps could be ready to order large quantities of the front-runner in its infantry automatic rifle competition this fall, but only if the commandant is convinced it’s a good idea.

The weapon has been in operational testing since January, and Marine officials overseeing the program hope “to get a full-rate production decision” once the results are reviewed, said Col. Andrew Bianca, head of infantry weapons acquisition at Marine Corps Systems Command.

Speaking to defense contractors April 6 in Baltimore, Bianca said the IAR’s development hinges in part on whether “everything works out” during testing.

“One of the big things that we’ve been doing — and most of you have probably read about it — is the infantry automatic rifle,” he told the group, gathered at SysCom’s 2010 Advanced Planning Brief to Industry.

“It’s a look at going back to the true automatic rifle and replacing the [M249] squad automatic weapon within the infantry squads and the light-armored reconnaissance scout teams.”

A decision to field the 5.56mm auto-rifle won’t be made unless Commandant Gen. James Conway is “satisfied that the IAR is the right weapon for the Marine Corps,” said Barbara Hamby, a SysCom spokeswoman.

Development of the 5.56mm IAR has been ongoing for years and widely discussed throughout the Corps. Marine officials intend to buy about 4,100 auto-rifles while reducing the number of SAWs from 11,381 to about 8,000.

Pros and cons
Conway has said that reducing the number of belt-fed, 5.56mm SAWs and their 200-round firepower could hurt a small unit’s ability to establish fire superiority.

Proponents of the auto-rifle program say its lightweight, 12½-pound design will improve accuracy, especially while on the move in a firefight. But some grunts worry about trading in the SAW for a rifle with a 30-round magazine.

Conway told reporters in December that replacing the SAW would be difficult in part because the weapon gives Marines a psychological advantage. Another hurdle, he said, would be convincing Congress to fund the IAR while the Army continues using the SAW.

“It’s a big deal when you start changing how a Marine infantry squad fights,” Conway said. “I’m going to have to be convinced that we’re making the right move before we start to purchase another system and change that whole dynamic.”

Marine officials are now testing Heckler & Koch’s IAR, after selecting it as its preferred option in October and ordering 24 additional weapons for testing. It beat out three other finalists, including two models from Colt Defense LLC, maker of the M4 carbine, and one from FN Herstal, maker of the SAW. The H&K model is a variant of its HK416 assault rifle, which uses a spring-buffered short-stroke gas piston system, and is the sole finalist that fires only from the closed-bolt position.

Testing has taken place in a variety of austere conditions and will continue through June. The results will be analyzed before any decision is made, and reviewed by both Conway and Brig. Gen. Michael Brogan, SysCom’s commander

Míssil X-51: ataca qualquer alvo no planeta em menos de uma hora


No dia 20 de Agosto de 1998 as agências secretas americanas localizaram Osama Bin Laden num campo de treino da Al-Qaeda no Afeganistão. Aos comandos políticos e militares abria-se uma oportunidade praticamente irrepetível para eliminar aquele que, muito antes do 11 de Setembro, era já um dos principais inimigos da América. Estacionado no mar Arábico, o USS Abraham Lincoln recebe ordens para lançar mísseis cruzeiro Tomahawk. A viagem (mesmo à velocidade de 880 quilómetros hora) demorou duas horas e quando os Tomahawk começaram a roncar nos céus afegãos já Bin Laden se tinha evaporado.

É verdade que as forças americanas têm no seu arsenal mísseis balísticos capazes de destruir qualquer alvo numa questão de minutos. Mas o problema destas armas é que a sua capacidade destrutiva é de tal modo excessiva que o seu uso é mais que improvável. Falamos, claro, das armas nucleares. "No ambiente estratégico actual, só temos zeros e uns. Podemos decidir usar armas nucleares ou não", confessa o capitão Terry Benedict, da marinha norte-americana.

Nos Estados Unidos nenhum estratego militar esquece o episódio de 1998. Por isto, e também por estar comprometida com um mundo livre do nuclear militar, a administração Obama está a trabalhar numa nova classe de armas convencionais capazes de atingir qualquer ponto do globo em menos de 60 minutos - ao mesmo tempo que mantém o poder de dissuasão americano.

No âmbito do programa Prompt Global Strike (Ataque Global Imediato), liderado pelo Departamento da Defesa, está a ser desenvolvido um novo míssil: o X-51. Utilizando tecnologia espacial da NASA, esta será a única arma não nuclear capaz de atingir velocidades Mach-5 (5793 quilómetros por hora) e que transforma em vantagens os efeitos brutais da velocidade hipersónica, destruindo os alvos aliando a força cinética a uma ogiva convencional.

"No papel estamos perante uma evolução tecnológica brutal. Mas os 'ses' só começam a aparecer na vertente operacional", explica ao i Francisco Galamas, investigador na área do armamento. De acordo com o Pentágono, este sistema nunca estará operacional antes de 2015 e o mais provável é que o seu desenvolvimento se prolongue até 2020. A nova arma pode ser lançada de um bombardeiro B-52 e é capaz de estilhaçar uma central nuclear iraniana ou norte-coreana, destruir um navio carregado de armamento no Médio Oriente ou ainda rebentar com o esconderijo de Bin Laden. Tudo com precisão extrema, em poucos minutos e com uma potência localizada equiparada à de uma bomba nuclear - sem a chacina inerente a uma bomba radiológica.

"A grande novidade deste sistema é combinar uma precisão quase cirúrgica com potência e uma capacidade quase instantânea de reacção", sustenta Galamas, alertando contudo para os problemas estratégicos que a implementação de um sistema deste tipo pode apresentar às potências rivais. "A Rússia já deu sinais de que pode vir a desenvolver o seu próprio sistema antimíssil."

Na força aérea americana espera-se que o X-51 seja mesmo uma realidade. "Tenho imensa confiança que vai funcionar", diz Mark Lewis, o cientista chefe da força aérea.

Apoio político, à partida, não faltará. Robert Gates, o secretário da Defesa, expressou na ABC o "acolhimento" que a administração deu ao Prompt Global Strike. Prova disso são os 250 milhões de dólares que Obama pediu ao Congresso para explorar esta alternativa, que combina tecnologia militar e aeroespacial de topo. John McCain, candidato presidencial republicano em 2008, também já manifestou o seu apoio a um programa que tem tanto de "caro como de essencial".

As reservas relativas à nova geração dos mísseis Trident, inicialmente pensados para incorporar o "Prompt Global Strike", fez com que muita gente no Departamento de Defesa se virasse para alternativas. A resposta deverá ser o X-51: uma arma que nos radares de Pequim ou Moscovo não é confundida com um míssil nuclear. Por isso, e como sustenta um oficial americano de topo, "ninguém se vai ter de preocupar em começar uma terceira guerra mundial."

Avião de combate britânico do futuro não tem tripulação





O Taranis, assim se chama esta verdadeira nave espacial, pode atingir alvos localizados em outros continentes

O Ministério da Defesa britânico divulgou esta segunda-feira as primeiras imagens de um protótipo de um avião não tripulado desenvolvido para combate. O aparelho, com semelhanças a uma nave espacial de um filme de ficção ciêntifica, foi baptizado com o nome de Taranis.

A novidade é a capacidade do avião em atingir um alvo localizado a grande distância, inclusivamente num outro continente, graças a um sistema de inteligência artificial.

Este protótipo ontem apresentado custou 171 milhões de euros e começou a ser construído em Dezembro de 2006. O Ministério da Defesa inglês prevê fazer o primeiro teste em 2011. "A taranis é um projecto verdadeiramente pioniero, que reflecte o design mais avançado e tecnologia de liderança no cenário mundial", disse Gerald Howart, ministro da segurança inglês.

O projecto da Taranis é uma parceria do Ministério da Defesa britânico com várias indústrias inglesas, uma delas a Rolls-Royce, que vai ser responsável pelo sistema de propulsão desta autêntica nave espacial.

Recorde de velocidade para heli - 225kt (417kmh)

 

Sikorsky says its X2 Technology demonstrator has reached 225kt (259mph) in flight tests - a milestone because it exceeds the word helicopter speed record of 216kt (249.1mph), set by a Westland Lynx in 1986.


Photo: Sikorsky

Record-setting G-LYNX was fitted with new blades developed under the British Experimental Rotor Program and now standard on AW101 and Lynx helicopters. The X2 has rigial coaxial rotors and a tail-mounted propulsor.

That propulsor makes the X2 a compound helicopter, so we Brits can console ourselves that the Lynx remains the fastest conventional helicopter - and will remain so even when Sikorsky achieves its avowed goal of exceeding 250kt.

G-LYNX also had uprated Rolls-Royce Gem 60 engines, cleared to their maximum contingency rating and further boosted by water methanol injection - so it was no standard Lynx. Sikorsky says the X2 will "cruise comfortably" at 250kt.


X2 tail (left to right) at 225kt, 181kt and first flight

The latest speed was set after the X2 was fitted with a redesigned tail to improve handling qualities and reduce pilot workload as speed increases. The attempt to achieve 250kt is now set for the third quarter, the company says.
