RIMPAC 2012 helicopters

Sea Hawk naval helicopter

Perhaps outlining the growing popularity of the helicopter market for fulfilling operational capabilities at sea, RIMPAC 2012 boasts a burgeoning contingent of participant helicopters. Nine nations will send helicopters to participate in the exercise to some extent, with differing purposes. The large helicopter fleet flying within RIMPAC 2012 can be explained by a number of frigates capable of hosting such helicopters present within the exercise.

Mexico will send its Mi-17 Hip helicopter, usually used to fulfil drug interdiction missions, whereas similar helicopters will be sent by nations including Japan, Singapore, Chile and Canada. Chile's HH-65 Dolphin helicopter, usually used for Coast Guard patrols and operations, will participate in the exercise, whereas Singapore intends to field its S-70B Seahawk fleet, flown by pilots of the Republic of Singapore Air Force.

Anti-submarine warfare appears to be a trend at RIMPAC 2012, with a number of anti-submarine patrol or warfare helicopters present. Japan, bound by its peaceful Constitution, will field its SH-60J Seahawk, usually reserved for anti-submarine patrol missions, whereas South Korea intends to deploy its Super Lynx MK. 99. The two nations will be joined by the US, Australia and Canada in fielding more attack-minded helicopters, including S-70B-2 Seahawks, CH-124A Sea Kings, MH-60R/B/S Seahawks and MH-53 Pave Lows.

Of the US fleet of helicopters participating in the exercise, particular attention should be afforded to the MH-60R and MH-60S Seahawk variants that will form part of the US Navy's Great Green Fleet, to be powered with a blend of algal-based biofuel and jet fuel as a demonstration of the US Navy's efforts to reduce its reliance on fossil fuels.

RIMPAC 2012 fighters, bombers and strike aircraft

F/A-18C hornet

F/A-18C Hornet attack aircraft.

Rather predictably given that the US is the only nation to field a carrier capable of hosting and launching such aircraft and so will be the only nation to field fighters, bombers or strike aircraft at this year's RIMPAC exercise.

Flying from the USS Nimitz at RIMPAC 2012 will be the only multirole fighter to be designated as a member of the US Navy's Great Green Fleet - the F/A-18 Hornet. The US Navy has achieved some success with Hornet aircraft and various blends of biofuel having successfully completed tests, making the aircraft a wise choice to demonstrate the progress made towards a more environmentally friendly and sustainable naval force.

The A-10 Thunderbolt II will also be present having gained a new lease of life earlier in 2012 after the US Air Force was forced to admit that its new F-35B cannot generate enough sorties to meet their needs. This has led the USAF to schedule for the A-10 to remain in service until at least 2028. Designed to provide close air support, the Thunderbolt is likely to play a part in a number of amphibious landing drills to involve South Korean Marine Corps units taking part in RIMPAC for the first time.

The A-10 and F/A-18 will be flanked by fellow attack aircraft the F-16 Fighting Falcon and F-15C Eagle, whereas the B-52 Stratofortress multirole bomber aircraft will also participate.

EA-6B Prowler tactical jamming aircraft.

The surveillance aircraft to participate in RIMPAC 2012 may come from a variety of different nations, but one aircraft presides over all other in terms of its popularity. All five nations to deploy surveillance aircraft, including Australia, New Zealand, Japan, South Korea and the US, will be fielding a variant of the Lockheed-built P-3 Orion maritime patrol and anti-submarine aircraft.

The inclusion of P-3 Orion aircraft from Japan, South Korea and the US is most likely a direct response to the sinking of ROKS Cheonan, which occurred in March 2010 and was allegedly due to a torpedo launched from a North Korean Yeono class miniature submarine. Although the United Nations Security Council never officially identified the aggressor, an investigation conducted by experts from South Korea, the US, the UK, Canada, Australia and Sweden came to the conclusion that a North Korean submarine was responsible. With tensions within the Korean peninsula continuing to rise and showing no signs of abating under the rule of Kim Jong-un, submarine detection within the Yellow Sea has obviously been thrust to the front of attention.

The US Navy will field an E-2C Hawkeye aircraft within its Great Green Fleet, whereas a US Navy EA-6B Prowler, a P-8A Poseidon and an E-3B/C Sentry aircraft will also participate in the exercise.

With a number of aircraft due to take part in various exercises under the RIMPAC umbrella, support aircraft will be supplied by the US and Canada. Canada will deploy KC-150T Polaris and KC-130T Hercules refuelling aircraft, with the Polaris aircraft used as air-to-air refuelling tankers for the Canadian CF-18 Hornet fleet, also due to participate in the exercise.

The US will deploy its C-17 Globemaster III tactical transport aircraft, C-2A Greyhound carrier on-board delivery aircraft and its KC-135R Stratotanker refuelling aircraft to support its and other nation's aircraft throughout the exercise's duration.

France - only vessel from western Europe

FS Prairial F 731 Floreal Class frigate

FS Prairial (F 731) Floréal Class frigate.

France will be the only western European nation to send a vessel for RIMPAC 2012, with its sole deployment for the exercise will be the Floréal Class frigate FS Prairial. FS Prairial's participation in the exercise is likely to be considered key given its ability to operate within littoral waters. Other Western European nations will be participating but not sending vessels, with both Norway and the UK sending a Combined Task Force and component staff contribution and Netherlands sending a fleet diving unit.

FS Prairial (F 731) - Floréal Class frigate

New Zealand - Anzac Class and AUVs

HMNZS Te Kaha F 77 Anzac Class frigate

RSS Formidable (68) Formidable Class frigate.

Singapore will be represented by the Formidable Class frigate RSS Formidable, a multi-mission derivative of the French Navy's La Fayette class frigates. Described as the "most advanced surface combatants in Southeast Asia", RSS Formidable's participation in RIMPAC 2012 follows up on RSS Supreme's deployment for RIMPAC 2010, where it participated in exercises within littoral waters.

RSS Formidable (68) - Formidable Class frigate

USA - submarines

USS North Carolina SSN 777 Virginia class submarine

USS North Carolina (SSN 777) Virginia class submarine.

The strong US contingent will be assisted by the presence of three submarines, most notably the Virginia Class attack submarine USS North Carolina, the fourth Virginia Class submarine to be commissioned by the US. The Virginia Class is the most advanced submarine at the US's disposal and comes at a price of approximately $2.4bn per unit.

The USS North Carolina will be joined by two Los Angeles class submarines, the USS Cheyenne and the USS Charlotte.

RIMPAC 2012: Great Green Fleet, communications and Yellow Sea security
12 June 2012 by Liam Stoker

Share on facebook Share on twitter Share on email Share on print More Sharing Services 10


More than 40 ships, six submarines and 200 aircraft are due to take part in the largest international maritime warfare exercise. As the world’s navies descend upon Hawaii for RIMPAC 2012, Liam Stoker analyses some key and emerging issues for this year’s exercise.

The Rim of the Pacific Exercise (RIMPAC) 2012, the world's largest international maritime warfare exercise, is scheduled to start on 29 June 2012. In all, 42 ships, six submarines, 200 aircraft and 25,000 personnel from 22 different nations will descend upon Hawaii, US, in an attempt to bolster interoperability between the US Navy and allied forces located within the Pacific Rim.

Not only is the exercise designed to increase stability in the region, but it also provides a key opportunity for participating naval forces to experiment with emerging technologies and concepts. Not only will the US Navy use RIMPAC 2012 to demonstrate its Great Green Fleet of biofuel-driven vessels, but it will also experiment with blue-laser communications technology which could revolutionise the development of submarines and remotely operated vehicles (ROVs).
US Navy's biofuel powered 'Great Green Fleet'

Making its first appearance at RIMPAC is the US Navy's Great Green Fleet, made up of aircraft and vessels such as the F/A-18 Super Hornet, the USS Nimitz and the USS Arleigh Burke-class guided missile destroyer, USS Chafee, which are powered using a biofuel blend to demonstrate the US Navy's development of a more environmentally-friendly naval force. The initiative is tasked with deploying a fleet of warships powered by alternative fuels by 2016.

Nimitz Class Aircraft Carrier

The Nimitz Class aircraft carriers are the largest warships ever built. With over 6,000 personnel (crew and aircrew), the carrier has a displacement of 102,000t, and a flight deck length of 332.9m.

The US Defence Logistics Agency has purchased 450,000 gallons of biofuel to power the navy's carrier group during the exercise, representing the largest single purchase of biofuel in history at a cost of $12m. A mixture of algae-based fuel and fuel developed from used cooking oil and non-food-grade animal fats has been ordered from Dynamic Fuels and Solazyme, which will be combined in a 50/50 blend with petroleum-based diesel and aviation fuel.

The testing hopes to build on the success of the Oliver Hazard Perry-Class frigate USS Ford's 12,000 mile trip using a biofuel blend, which it completed in March 2012. US surface combatants and carrier-based aircraft will be used to "test, evaluate and demonstrate the cross-platform utility and functionality of biofuels", according to the US Navy.

The investment into biofuel research has not, however, been without controversy. The US Department of Defence has been met with a political backlash for what some politicians have labelled as a misdirection of resources, which should be diverted towards the acquisition of new vessels instead.

As questions continue over why the navy's ship budget has been slashed but investment into expensive biofuels has increased, Navy Energy Coordination Office director James Goudreau said: "Alternative fuels for the navy is not about being green, it's about combat ability."

Despite Goudreau's assertion, Republicans on the House Armed Services Committee have still attempted to ban the US Navy from producing or buying any alternative fuels which cost more than traditional fossil fuels.
Submarine-friendly blue laser communications

Another area which has captured the US Navy's attention is the advancement of blue-laser communications technologies, which will be field tested during RIMPAC 2012.
Related project
NSSN Virginia Class Attack Submarine

The Virginia Class new attack submarine is an advanced stealth multimission nuclear-powered submarine for deep ocean anti-submarine warfare and littoral (shallow water) operations..

Should testing prove to be successful, the technology could not only enhance communications between submarines and assets above the surface, but also make the use of ROVs more feasible.

The current standard of communications relies upon radio waves, which cannot penetrate through sea water. This has led to submarines requiring the use of towed buoys or trailing wires to communicate with warships or aircraft effectively. Blue / green laser wavelengths are, however, capable of penetrating sea water effectively and have been eyed as a potential communication medium for some time.

The stumbling block which has prevented previous use aboard submarines has been the laser transmitter. It is a required component for the system, but usually either a Raman shifted XeCI examiner laser or a frequency-doubled Ti Sapphire source is considered too bulky, inefficient and impractical for installation aboard modern submarines, where space is at a premium and demands are high.

This prompted DARPA to award a $32m contract in September 2010 to develop a blue-laser system under the Tactical Relay Information Network (TRITON) programme, with a live evaluation of the system scheduled to take place during RIMPAC 2012.

A Broad Agency Announcement from DARPA signalled RIMPAC as a key event during the system's development, adding: "By programme completion, DARPA and the navy are expecting a clear demonstration of the maturity of key laser technology components and its performance as a future operational system."

QinetiQ's North American subsidiary secured the contract having already started development of a blue-laser communication system dubbed the Submarine-Enabling Airborne Data Exchange and Enhancement Program (SEADEEP).

At the time of the contract award, QinetiQ confirmed that its SEADEEP system had already demonstrated "communications through the air-water interface equivalent to data rates available with wideband Internet communications at home", equivalent to being hundreds of times faster than conventional submarine communications at operational depths.
Addressing increasing instability on the Korean Peninsula

Aside from the operational testing of emerging technologies, RIMPAC 2012 will also see participating nations conduct a number of drills and exercises designed specifically to increase interoperability.
Related project
Sejong the Great Class Destroyer

The Sejong the Great Class guided missile destroyers are being developed under the Korean Destroyer eXperimental (KDX) programme of the Republic of Korea Navy (ROKN).

South Korea will be hoping that its contingent of the ROKS Yulgok Yi-I and Choi Young destroyers, the Chang Bogo-Class submarine, a P-3C surveillance plane and a Lynx anti-submarine helicopter will help establish itself as a key participant in the exercise amid a backdrop of escalating tensions in the Korean Peninsula.

March 2010 saw the sinking of ROKS Cheonan and the deaths of 46 South Korean sailors. Suspected to be the result of an attack from a North Korean submarine, tensions in the region mounted as the US condemned the attack without explicitly naming North Korea as the perpetrator. This was followed by the North Korean shelling of Yeonpyeong Island in November 2010, killing two civilians and two soldiers.

Former UN ambassador Bill Richardson said after the bombardment of Yeonpyeong that tensions had become "the most serious crisis on the Korean Peninsula since the 1943 armistice which ended the Korean War."

Escalating tensions, enhanced by Kim Jong-Il's death and North Korea's recent failed satellite launch, have resulted in a degree of uncertainty in the Yellow Sea region and Korean Peninsula, but the US will hope to alleviate fears with South Korea's participation in the exercise.

Although South Korea has been a repeat participant in the exercise since 1990, RIMPAC 2012 will see the first demonstration of a South Korean marine platoon in order to boost amphibious landing operational capabilities, in what could be seen as a direct response to the bombardment of Yeonpyeong.

Si te refieres a esta, es una imagen de archivo que no corresponde al actual Usumacinta, de cuando todavia servia en la US Navy con el numeral 1179, visible en la imagen, mientras el actual es el 412. Son sus dueños originales los que traian asi al buque (que no es nada raro con despliegues prolongados de hasta seis meses o mas).

Su p****e madre las piernas de la vieja (ver tamaño original de la foto)

Que onda con sus pantalones entubados? jajaja

excelente esas fotos, y jejejeje ese de los pantanos entubado tss se ve conque ton

'No es raro ver pantalones 'entubados' en la IM, aun que como que este si exagero

Asi marca la directiva para uniformes que los deben de portar. En lo personal no es de mi mayor agrado, pero no se ve tan mal despues de todo

Por cierto ya sacaron otras mas de un Cap Frag y ademas otras del Usumacinta

yo nunca avía visto un infante con ese tipo de pantalones pero para mi no me gusta como se ve

Pues no se en que pais vives Master, toda la IM los usa asi. (Es de señalarse que los Lanceros de Colombia tambien)

jajajaja que paso mi lanceros me ofende es obvio que vivo en México, pero el caso es que no me pongo a ver los que ropa traen si los ves luego luego imponen con las miradas jajajaja

Ay esos boludos... como siempre sin saber doblarse las mangas del uniforme y sin ponerse bien el chaleco. Error sistemico de la Armada de Mexico...pero al Mando le vale madre desde hace años... si los mismos oficiales luego dan lastima de la forma en la que se uniforman, generalmente las excepciones son de Infanteria de Marina y algunos fibras oficiales Nucleo de Cuerpo General.

Ni hablar.

Son modelo Porsi...

Porsillueve jajajajajajaja

jajajajaja no maaaa!!

Jajaja yo lo que hacia es que a la hora de entubarlos los dejaba un poco mas flojitos, pero aun haciendo el mismo dobles, me era mas comodo, y aun se veia como marcaba las disposiciones del mando

Que buen video compa.

aquí les comparto un vídeo que me encontré (;

Que bien por la armada de mexico, y espero que continuen participando en más ejercicios y no salgan conque no les dan permisos.
