According to the information Izvěstijí have additional tests may be conducted during July to August 2013 on the polygon in Achtjubinsku in Astracháňské area. At them should be first achieved at 5 Ma, and more. At the same time to be expanded the parameters of the missile, the flight time has to be extended and its engine will work in multiple modes. The beginning of the nineties of the last century was in the MKB Raduga developed the project hyperzvukového of the flying apparatus (гиперзвуковой экспериментальный летательный аппарат - ГЭЛА). In the terminology of NATO, these machines are called hypezvuková wing rocket. This particular missile was given the designation AS-19 Koala (the designation AS-X-19 was used for its predecessor křídlatou rocket Meteor). Wing rocket (KR) Ch-90 Koala was from the first time developed for military use, set the requirement at a range of 3000 km and was intended to replace KR Ch 55. KR Ch-90 Koala can carry two individually guided warheads (MaRV), which are able to destroy two different objectives, which can be separated by a distance of up to 100 km. As the carrier is designed aircraft Tu-160M. Development work was in 1992 due to lack of finance suspended.
Visitors to the exhibition MAKS-95 could KR Ch-90 on outdoor static display at the pavilion MKB Raduga. Ch-90 has a length of around 12 m and is equipped with hyperzvukovým náporovým engine, which uses fuel-based petroleum products (kerosene). Launch KR is carried out y the aircraft as the basic carrier is designed modernized aircraft Tu-160 (with extended fuselage), can fit into it 2 shots. As the second carrier can be appropriately modified Tu-95.
After separation from the aircraft carrier (the deletion) is KR given basic velocity using the rocket engine on solid fuel, it must be in the supersonic region, because only then can you start to work hyperzvukový is converted into impact engine. He is able to grant Ch-90 Koala speed of M=4 to 5.
