do you know how many countries uses Mi 35 of russia and how many countries uses cobra u will see the difference czesh republic easily can buy cobras but they went with mi 35 why are they made cobra is light weight very good helicopter no doubt weapons which it carrries anti tank TOW it can not panetrate the armour of T 90 tank and i think future generation of attack helicopters should be buyed to fight against lattest tanks in war why usa hugely buys apaches not cobras infact usa will phase them out untill 2015 so please use your mind fighting with terrorist cobra is lethel even in war too but it does not have compitable fire power of weapons liks of hellfire missile, and its rotary makes too much noise too so enemy can know what coming to their way in apache and havoc blades 70% more silent than cobras,Near Real-Time situational awareness schematic,
these things dont have in cobra
The Longbow Apache can effect an attack in 30 seconds. The radar dome is unmasked for a single radar scan and then remasked. The processors determine the location, speed and direction of travel of a maximum of 256 targets.
The target acquisition designation sight, TADS (AN/ASQ-170), and the pilot night vision sensor, PNVS (AN/AAQ-11), were developed by Lockheed Martin. The turret-mounted TADS provides direct-view optics, television and three-fields-of-view forward-looking infrared (FLIR) to carry out search, detection and recognition, and Litton laser rangefinder / designator. PNVS consists of a FLIR in a rotating turret located on the nose above the TADS. The image from the PNVS is displayed in the monocular eyepiece of the Honeywell integrated helmet And display sighting system, IHADSS, worn by the pilot and copilot / gunner.
"The AH-64D Longbow Apache is equipped with the Northrop Grumman millimetre-wave Longbow radar."Lockheed Martin has developed a new targeting and night vision system for the Apache, using second-generation long-wave infrared sensors with improved range and resolution. The new system is called Arrowhead and has a targeting FLIR with three fields of view, a dual field-of-view pilotage FLIR, a CCD TV camera, electronic zoom, target tracker and auto-boresight. Arrowhead entered production in December 2003 and the first unit was delivered to the US Army in May 2005. 704 US Army Apaches are to be equipped with Arrowhead by 2011.
A contract to equip the UK AH Mk1 helicopters with Arrowhead was placed in May 2005. Deliveries are scheduled for between 2009 and 2010.
Countermeasures
The Apache is equipped with an electronic warfare suite consisting of: AN/APR-39A(V) radar warning receiver from Northrop Grumman (formerly Litton) and Lockheed Martin; Lockheed Martin AN/APR-48A Radar Frequency Interferometer Electronic Support target acquisition system; AN/ALQ-144 infra-red countermeasures set from BAE Systems IEWS (formerly Sanders, a Lockheed Martin company); AN/AVR-2 laser warning receiver from Goodrich (formerly Hughes Danbury Optical Systems then Raytheon); AN/ALQ-136(V) radar jammer developed by ITT; and chaff dispensers.
US Army Longbow Apaches were to be fitted with the ITT AN/ALQ-211 SIRCM (suite of integrated radio frequency countermeasures) suite, however the availability of funding for this project is uncertain.
UK AH mk1 Apaches are fitted with BAE Systems helicopter integrated defensive aids suite (HIDAS), also chosen by Kuwait and Greece. HIDAS, which includes the Sky Guardian 2000 radar warning receiver, entered service on the AH mk1 in July 2003.
Israeli AH-64D helicopters are fitted with the Elisra Seraph self-protection system, including SPS-65 missile warner and SPJ-40 radar jammer.
Dutch AH-64D helicopters are being fitted with the Northrop Grumman directional infrared countermeasures (DIRCM) pod.
