Effective against low altitude targets The Soviet S-125M NEVA short range airspace defence missile system could destroy low altitude targets. It could direct two missiles at a target if its speed did not exceed 750 m/s. In Hungary a modernised four-track launching stand S-125M was in service from 1978 to 2001. NATO reporting name: SA-3 Goa. It was developed in the 1960s In the mid-1960s the Soviet Union began developing a high speed, low altitude air defence missile system effective against high mobility [fast moving? Or highly manoeuvrable?] targets. Initially the NEVA system was deployed with a two-rail launching stand in 1965. The missiles were produced in high volume and exported. The marine version was the M-1 Volna. On 27 March, 1999, the Serbian army used NEVA to shoot down an American F-117 stealth bomber. It defended Budapest In October of 1977 the 11th air defence missile brigade was formed from a previous battalion, whose task was to ensure the safety of the capital's airspace The brigade was stationed at missile stations 11/9-14 Tinnye, Bián, Szigethalom, Pilisszentlászló, Gyál and Kerepes, which were armed with NEVA systems in October 1978. The last batteries armed with NEVA were decommissioned in 2001. Construction and function The NEVA divisions were given 3 provisions, that is 48 V-601P type air defence missiles. The divisions consisted of 13 officers, 20 sergeants, 116 general infantry and 4 civilian employees. The system controls and the commanding officer's station were in the UNK cabin and the UNV antenna stand respectively. The NEVA system had a TV-optic targeting system and interference protection. The launching system consisted of a missile preparing-repairing group and two fire groups, with four four-rail launching stands each. The V-601P is a two-stage missile, and both stages work with solid fuel. The missile's steering flaps are positioned in front of the wings. The TZM, constructed from a ZIL-131 and a PR-14AM, could ensure transport for two missiles. The system was made up of the following parts: - UNK-trailer - UV-550 (antenna stand) - UV-600 antenna part - RKU-N cabin - 5E96 cabin - PRM-N cabin - 5P-73 launch stand - TZM transport and loading machine
