The Boeing AH-64 Apache is an American four-blade, twin-turboshaft attack helicopter with a tailwheel-type landing gear arrangement and a tandem cockpit for a two-man crew. It features a nose-mounted sensor suite for target acquisition and night vision systems. It is armed with a 30 mm (1.18 in) M230 chain gun carried between the main landing gear, under the aircraft’s forward fuselage, and four hardpoints mounted on stub-wing pylons for carrying armament and stores, typically a mixture of AGM-114 Hellfire missiles and Hydra 70 rocket pods. The AH-64 has a large amount of systems redundancy to improve combat survivability.
The Apache originally started as the Model 77 developed by Hughes Helicopters for the United States Army’s Advanced Attack Helicopter program to replace the AH-1 Cobra. The prototype YAH-64 was first flown on 30 September 1975. The U.S. Army selected the YAH-64 over the Bell YAH-63 in 1976, and later approved full production in 1982. After purchasing Hughes Helicopters in 1984, McDonnell Douglas continued AH-64 production and development. The helicopter was introduced to U.S. Army service in April 1986. The first production AH-64D Apache Longbow, an upgraded Apache variant, was delivered to the Army in March 1997. Production has been continued by Boeing Defense, Space & Security; over 2,000 AH-64s have been produced to date.
The U.S. Army is the primary operator of the AH-64; it has also become the primary attack helicopter of multiple nations, including Greece, Japan, Israel, the Netherlands, Singapore, and the United Arab Emirates; as well as being produced under license in the United Kingdom as the AgustaWestland Apache. American AH-64s have served in conflicts in Panama, the Persian Gulf, Kosovo, Afghanistan, and Iraq. Israel used the Apache in its military conflicts in Lebanon and the Gaza Strip; British and Dutch Apaches have seen deployments in wars in Afghanistan and Iraq.
The AH-64 Apache has a four-blade main rotor and a four-blade tail rotor. The crew sits in tandem, with the pilot sitting behind and above the co-pilot/gunner. Both crew members are capable of flying the aircraft and performing methods of weapon engagements independently. The AH-64 is powered by two General Electric T700 turboshaft engines with high-mounted exhausts on either side of the fuselage. Various models of engines have been used on the Apache; those in British service use engines from Rolls-Royce. In 2004, General Electric Aviation began producing more powerful T700-GE-701D engines, rated at 2,000 shp (1,500 kW) for AH-64Ds.
The crew compartment has shielding between the cockpits, such that at least one crew member can survive hits. The compartment and the rotor blades are designed to sustain a hit from 23 mm (0.91 in) rounds. The airframe includes some 2,500 lb (1,100 kg) of protection and has a self-sealing fuel system to protect against ballistic projectiles. The aircraft was designed to meet the crashworthiness requirements of MIL-STD-1290, which specifies minimum requirement for crash impact energy attenuation to minimize crew injuries and fatalities. This was achieved through incorporation of increased structural strength, crashworthy landing gear, seats and fuel system.
On a standard day where temperatures are 59 °F (15 °C), the AH-64 has a vertical rate of climb of 1,775 feet per minute (541 m/min), and a service ceiling of 21,000 feet (6,400 m). However, on a hot day where temperatures are 70 °F (21 °C), its vertical rate of climb is reduced to 1,595 fpm (486 m/min), and service ceiling is reduced to 19,400 feet (5,900 m) due to less dense air.
In Syria’s Skies, Close Calls With Russian Warplanes
AL UDEID AIR BASE, Qatar — Russian fighter jets have flown dangerously close to American warplanes in eastern Syria over the past month — including one near-collision — in what American
officials say is a pattern of daily Russian violations of an agreement to separate rival forces converging on the last main pocket of Islamic State militants in the country.
Every day, an American Air Force officer calls his Russian counterpart at an air base in Latakia,
Syria, to head off, or “deconflict,” as the military says, any potential problems over Syria.
“The greatest concern is that we could shoot down a Russian aircraft because its actions are seen as a threat to our air or ground forces.” The setting was similar last June in southern Syria, when American warplanes shot down a Syrian Air Force Su-22
and two Iranian-made drones after they had threatened American-backed militia forces.
President Vladimir V. Putin of Russia declared on Wednesday
that the Islamic State in eastern Syria had suffered a “complete defeat” — a boast that American officials said exaggerated Moscow’s role and seemed to ignore the contentious efforts to rout the remaining 3,000 Islamic State disciples still on the run.
The Air Force pilots showed restraint, but given that the actions of the Su-24 could have reasonably been interpreted as threatening to
the American aircraft, the F-22 pilots would have been with their rights to fire in self-defense, officials at the Qatar air base said.
Syria said that There’s risk there,
Syrian Army troops backed by Russian air power and Iranian militia are advancing along the western side of the river; Syrian Arab
and Kurdish fighters, supported by American warplanes and Special Operations advisers, are pushing along the eastern river banks.
Battle Royale Over Rightful Heir to Israeli Self-Defense Discipline
Mr. Lichtenfeld’s association and its disciples spawned other organizations such as the Krav Maga Federation, the Israeli Krav Maga Federation, Krav Magen
and Krav Maga Global, all considered reputable and authentic schools and all vying for business abroad.
His Krav Maga Global organization’s website credits him as being “the only person in the world to whom Imi presented the ‘Founders Diploma of Excellence.’ ” Ran Nakash, 39, who led courses for the military’s Krav Maga instructors
and runs a boxing and Krav Maga gym in Tel Aviv, called the argument over Mr. Lichtenfeld’s legacy nonsense.
David Kahn said that The martial arts world is replete with controversy about who is the top instructor within a given discipline,
There is no competitive Krav Maga circuit, because the idea is to break all the rules, not
play by them, although the army did institute an annual Krav Maga contest a few years ago.
Krav Maga, the rough, close-combat self-defense system developed in the Israeli military, has
become a mainstay of special forces training here and an increasingly popular Israeli export.
Mr. Gidon said he preferred to remain above the fray regarding seniority in the Krav Maga world.
In the state of West Bengal Chief Minister Mamata Banerjee, Bajrang Dal has given training to the youth like military.

Russia Says Its Syria Bases Beat Back an Attack by 13 Drones
MOSCOW — The main Russian air and naval bases in Syria beat back an attack by 13
armed drones over the weekend, the Russian Ministry of Defense said on Monday.
It said 10 assault drones had flown toward the Hmeimim air base in northwestern Syria, while another
three were directed against the Russian naval station at Tartus on the Mediterranean Sea.
The military denied Russian news media reports that seven military aircraft had been destroyed or damaged by rebel shelling in the Dec. 31 attack,
although a few posts on social media showed what was described as damaged aircraft, including a mangled rear stabilizer on one military jet.
The Russian military said the drone attack was the first such coordinated assault it had experienced against
its bases in Syria, with the drones flying from about 30 miles away and guided by a GPS unit.
Accounts by opposition members and others in Syria said one of the Islamist factions
operating near the northwestern city of Latakia had launched the drone attack.
In its latest announcement, the Ministry of Defense said the drone attack had occurred overnight last Friday.
