When combined with the AIM-9X, an advanced short-range dogfight weapon that employs a Focal Plane Array seeker and a thrust vectoring tail control package, JHMCS allows effective target designation up to 80 degrees either side of the aircraft's nose. In March 2009, a successful 'Lock on After Launch' firing of an ASRAAM at

5644-410: The pilot. These systems allow targets to be designated with minimal aircraft maneuvering, minimizing the time spent in the threat environment, and allowing greater lethality, survivability, and pilot situational awareness . In 1962, Hughes Aircraft Company revealed the Electrocular , a compact CRT , head-mounted monocular display that reflected a TV signal onto a transparent eyepiece. One of

5727-409: The rear of the body midsection. Two turboshaft engines in pods are mounted alongside the top of the fuselage with downturned exhausts. The fuselage is slender and tapers to the tail boom and nose. It features tandem, stepped-up cockpits, a cannon mounted beneath the belly, and a non-retractable tricycle tail-wheel type landing gear. Due to the energy-absorbing landing gear and seats the crew can survive

5810-428: The risk of confusion, unusual or made-up names are allocated, the idea being that the names chosen are unlikely to occur in normal conversation and are easier to memorise. For fixed-wing aircraft, the number of syllables indicates the type of the aircraft's engine. Single-syllable code names denote reciprocating engine or turboprop , while two-syllable code names denote jet engine . Bombers have names starting with

5893-435: The stub wings. Typical rockets carried are the 122 mm (4.8 in) S-13 , fired from five-round B-13 rocket pods, and the 80 mm (3.1 in) S-8 , fired from 20-round B8V-20 pods. The S-8 and S-13 rockets used by the Mi-28 are usually unguided. In the most common configuration, one can expect 40 S-8 rockets or 10 S-13 rockets. Both rockets have their variants, from HEAT warheads to thermobaric warheads. The S-8 has

5976-596: The three-blade version. The Mi-28A debuted at the Paris Air Show in June 1989. In 1991 the second Mi-28A (no. 042) was completed. The Mi-28A program was cancelled in 1993 because it was deemed uncompetitive with the Ka-50, in particular it was not all-weather capable. The Mi-28N was unveiled in 1995, the N designation meaning "night". The prototype (no. 014) first flew on 14 November 1996. Its most significant feature

6059-586: The type had been accepted for service with the Kenyan military. In April 2010, Venezuela agreed to order 10 Mi-28s for the Venezuelan Army . However, no deal was signed after this. Data from RIA Novosti, Russian Helicopters, JSC, Jane's All The World's Aircraft 2000–2001 General characteristics Performance Armament Related development Aircraft of comparable role, configuration, and era The initial version of this article

6142-722: The unified German Air Force. One successful HMD was the Israeli Air Force Elbit DASH series, fielded in conjunction with the Python 4 , in the early 1990s. The U.S., UK, and Germany pursued a HMD combined with ASRAAM systems. Technical difficulties led to the U.S. abandoning ASRAAM, instead funding development of the AIM-9X and the Joint Helmet-Mounted Cueing System in 1990. American and European fighter HMDs became widely used in

6225-675: The user where head protection is required – most notably in military aircraft. The display-optics assembly can be attached to a helmet or integrated into the design of the helmet. An HMD provides the pilot with situation awareness , an enhanced image of the scene, and in military applications cue weapons systems , to the direction their head is pointing. Applications which allow cuing of weapon systems are referred to as helmet-mounted sight and display (HMSD) or helmet-mounted sights (HMS). Aviation HMD designs serve these purposes: HMD systems, combined with High Off- Boresight (HOBS) weapons, allow aircrew to attack and destroy nearly any target seen by

6308-421: The weapons required to fulfill that particular task. The integrated surveillance and fire control system has two optical channels providing wide and narrow fields of view, a narrow-field-of-view optical television channel, and laser rangefinder . The system can move within 110 degrees in azimuth and from +13 to −40 degrees in elevation. The night attack variant helicopter retains most of the structural design of

6391-513: The wreck of a Mi-28 was found by Ukrainian forces outside the town of Hostomel in the Kyiv Oblast . The craft was likely destroyed during the Battle of Hostomel Airport . On 9 May, one Mi-28 was destroyed in north of Kharkiv , the attack helicopter with registration number RF-13654 was the third visually reported loss of that type. On 16 May, another Mi-28N with registration number RF-13628

6474-498: Was assigned to an attack submarine by NATO, was the actual Soviet name for the ballistic missile submarine NATO named " Typhoon-class ". The NATO names for submarines of the People's Republic of China are taken from Chinese dynasties . Helmet-mounted display A helmet-mounted display ( HMD ) is a headworn device that uses displays and optics to project imagery and/or symbology to the eyes. It provides visual information to

6557-727: Was based on material from aviation.ru . It has been released under the GFDL by the copyright holder. NATO reporting name The assignment of reporting names is managed by the Five Eyes Air Force Interoperability Council (AFIC), previously known as the Air Standardization Coordinating Committee (ASCC), which is separate from NATO . Based in Washington DC, AFIC comprises representatives from

6640-544: Was completed in 1983. In 1984, the Mi-28 completed the first stage of state trials, but in October 1984 the Soviet Air Force chose the more advanced Kamov Ka-50 as the new anti-tank helicopter. Mi-28 development continued, but given lower priority. In December 1987, Mi-28 production at Rosvertol in Rostov-on-Don was approved. An early production Mi-24 was fitted with an air data boom as an early test for

6723-425: Was designed to be installed on a standard issue HGU-55/P and HGU-68/P helmets and is fully compatible with standard issue U.S. Pilot Flight Equipment without special fitting. It is also fully compatible with standard unmodified AN/AVS-9 Night Vision Goggles (NVG) and Panoramic Night Vision Goggles (PNVG). Pilots, using Scorpion, can view both the night vision image and the symbols on the display. Scorpion uses

6806-547: Was destroyed in Kharkiv. On 12 June 2022, a Mi-28N was destroyed and its wreck recorded in video by Ukrainian troops, the crew of the helicopter died at the crash site. On 18 September 2023, the Ukrainian military intelligence claimed a raid against Chkalovsky Air Base , near Moscow , occurred. During which they claimed damaged the tail rotor of a Mi-28N. It had been used in the shooting down of Ukrainian drones, according to

6889-459: Was subsequently acquired by Thales in 2012. The HMIT system was qualified and deployed on both A-10 and F-16 platforms in 2012. Starting in 2018, the installed base of HMIT systems went through a helmet tracker upgrade. The original AC magnetic tracking sensor was replaced by an inertial-optical hybrid tracker called Hybrid Optical based Inertial Tracker (HObIT). The HObIT was developed by InterSense and tested by Thales in 2014. Scorpion has
