Elbit Systems lands helmet-mounted display deal with South Korea
By Arie Egozi

Elbit Systems has received a contract to supply advanced helmet-mounted display systems for the South Korean army's Korean Utility Helicopter (KUH) programme.

Under the deal, Elbit will supply prime contractor Korea Aerospace Industries with equipment for its ongoing development effort, which is expected to lead to the manufacture of up to 250 tactical transport helicopters. The Israeli company's initial contract covers those development aircraft due to be delivered in 2009-10, but it believes the agreement could lead to follow-on orders to equip the entire KUH fleet and additional military rotorcraft.

"We believe this selection will lead to further head-up display projects in South Korea and worldwide," says Yoram Shmuely, co-general manager of Elbit's Aerospace Division.

Elbit says its helmet-mounted display systems enable helicopter pilots to fly with their "head out of the cockpit", boosting situational awareness and safety by projecting essential flight data, plus navigation waypoints and threat data into their line of sight.

Un sous-marin nord-coréen a quitté sa base peu avant que le Cheonan coule


Au milieu des spéculations que la corvette sud-coréenne Cheonan a été coulée par une torpille lancée par un sous-marin ou un semi-submersible nord-coréen, les services de renseignement sud-coréens et américains auraient détecté vendredi dernier le départ puis le retour d’un sous-marin dans une base nord-coréenne sur la côte ouest, pas loin du lieu où l’épave a été retrouvée.

Une source du gouvernement sud-coréen a déclaré mardi que "l’examen des images prises par les satellites espions américains révèle qu’un sous-marin de la base navale de Sagot en Corée du Nord, à quelques 50 km de l’île de Baeknyeong, a disparu quelques jours avant vendredi dernier et est retourné à sa base ensuite."
La source indique que des sous-marins ou des submersibles nord-coréens "disparaissent parfois de leur base et reviennent ensuite. Donc, il est difficile pour l’instant de faire le lien avec le naufrage du Cheonan. Nous sommes actuellement en train d’établir les circonstances exactes."
Le ministre sud-coréen de la défense, Kim Tae-young, avait déclaré lundi devant la commission de la défense de l’Assemblée Nationale sud-coréenne que les semi-submersibles nord-coréens pouvaient lancer 2 torpilles.
La base de Sagot abrite les forces navales de la côte ouest de la Corée du Nord, dont quelques 20 sous-marins et semi-submersibles.

Seoul Dispatches Mine Hunters to Study Warship Disaster
The South Korean Navy has deployed mine detector ships to search for any signs that the 1200-tonne warship ROKS Cheonan was sunk by North Korea.
Defence ministry spokesman Won Tae-jae said there were no abnormal activities by North Korean submersible craft or submarines in relation to this incident, according to straitstimes.com.
South Korea found no evidence regarding the involvement of North Korea in the incident, despite earlier speculating that a North Korean mine, either drifting or deliberately placed, might have caused the disaster.
A 60-member investigation team of military and civilian experts, including specialists in naval weaponry, explosives and shipbuilding engineering, are searching the area for possible shrapnel or parts of a torpedo or mine, according to a spokesman for the South Korean Joint Chiefs of Staff.

Sensor Fuzed Weapon to Armour South Korean Combat Aircraft
The South Korean air force's FA-50 light combat aircraft will be armoured with the Sensor Fuzed Weapon (SFW) system to enhance its target acquisition capability.
The weapon system is claimed to accurately detect and defeat a wide range of moving and stationary land and maritime target threats over a wide area with minimal collateral damage.
SFW contains BLU-108 submunition and smart Skeet warheads equipped with dual-mode passive infrared and active laser sensors.
Textron Defense Systems will deliver the systems to the Republic of Korea Air Force.

South Korean Navy Grounds Lynx Helos


SEOUL - The South Korean Navy has suspended its fleet of Lynx anti-submarine helicopters following the back-to-back crashes of two of them last week.

The service ordered emergency safety inspections of the British helicopters, a Navy official said April 19. Investigators are looking into the cause of the crashes at the same time, he said.

The Navy had operated 25 Lynx helicopters modified for anti-submarine and surface warfare. The first batch of 12 Mk.99 Lynx helicopters was delivered to the service in 1990, and the second batch of 13 Mk.99A Super Lynx helicopters in 1999.
Possible causes include an engine problem and pilot fatigue, said the official.
The export variants for South Korea are powered by two Rolls-Royce Gem 42-1 engines, whose production was halted years ago. The Navy therefore has had difficulty supplying the Gem engines but managed to secure used engines from the Royal Navy, he said.
"Investigators are looking into all possible causes of the crashes, including an engine problem, but nothing has been confirmed," the spokesman said.
Alexander W. Jun, regional director of Rolls-Royce Korea, said, "It's true that the production of the Gem engine has been suspended, but there was not much difficulty in supplying the ROK Navy with the engine."
On April 15, a Lynx crashed off the country's southwest coast, leaving one pilot dead and three other crew members missing. The helicopter disappeared from radar at 8:53 p.m. after losing contact with its fleet command while patrolling 15 kilometers off the coast, according to the Joint Chiefs of Staff (JCS).
The JCS denied an allegation that the Lynx had been responding to an invasion by a North Korean submarine.
"The helicopter was on a routine nighttime mission," JCS spokesman Col. Park Sung-woo said.
The incident occurred as the country's military was being placed on a high alert following the sinking of one of its warships in waters off the disputed sea border with North Korea.
The 1,200-ton corvette Cheonan, with 104 crew members on board, went down after an unexplained explosion. Fifty-eight sailors were rescued before the ship sank, but 46 others were missing. The bodies of 38 sailors have been recovered while eight others remain missing.
A joint investigation team involving civil and military experts is probing into the cause of the sinking, with more evidence suggesting an external impact caused by a torpedo attack or a mine explosion.
The other Lynx crashed at 22:13 p.m. April 17 in waters off the west coast on its way back to a destroyer after chasing "unidentified targets" near an island off the sea border, the JCS said. The targets were later confirmed as a group of birds, it said in a news release.
The helicopter made an emergency landing and the three pilots aboard were rescued, said the release. The helicopter was largely undamaged and was later retrieved, it said.

Oui,tout à fait d'accord!!!

On peut voir comme le projectile est directement allé vers la salle des machines, ce qui fait penser à un système de guidage acoustique comme celui de n'importe quel torpille...
