SF2 SA-7 Grail / 9K32 Strela-2 MANPADS Pack 1.5 ----------------------------------------------------------------------------------------- This pack features the famous SA-7 "Grail". It is a man-portable, shoulder-fired, low-altitude, infrared guided surface-to-air missile system (MANPADS). It is widely exported and has been in use in nearly every regional conflict since 1969. Despite its operational limitations, it has been proved quite effective in the hands of tactical armies and rebel groups. During War of Attrition on 19 August 1969 Egyptian soldiers brought down an Israeli A-4H Skyhawk some miles west of the Suez Canal using Strela-2. According to some sources this might have been the first successful combat use of any MANPADS in history! Following variants are included: 9K32 Strela-2 (SA-7A, 1968) - First variant. 9K32M Strela-2M (SA-7B, 1970) - Improved variant. ------------------------------------------------------------------------------------------ New features: - Updated missiles data which offer more realistic performance - Fuze distances have been increased since the SA-7 had lethality limitations after hitting a target. Now a target can be hit but it may return back home safely - New launch effect and sound ------------------------------------------------------------------------------------------ Known issues: - Due to game engine limitations concering missile guidance, 9M32 (SA-7A) missile's target aspect has been set as Rear 180 despite the fact that in reality it could be fired only at the rear. After massive failed launches it became clear that it was extremely difficult to achieve a single hit by setting 9M32 as Rear 60 even when some other values such as FOV and track rate had been increased. - Helicopters have higher survival rate per hit because in some cases missiles hit the tail rotor without causing significant damage. I guess this is another game engine characteristic. - Low altitude (lower than 600-800m) performance is downgraded for current missile values. By increasing noise rejection the missile becomes capable of hitting targets in lower altitude but at the same time the single shot hit/kill probability is being increased to an unrealistic level. - Fuze distances are longer compared with the actual lethal and damage radius of the system. In SF2 world the real high explosive warhead quantity is big enough to destroy a fighter size target even in 10 meters! ------------------------------------------------------------------------------------------- As always open readme.txt first to see installation instructions and credits. Lot of research and hard work was made to make this SAM as realistic as possible. More than 2000 launches took place!

SF2 SA-14 Gremlin / 9K34 Strela-3 MANPADS Pack 1.0 ------------------------------------------------------------------------------------------------------- This pack features the SA-14 Gremlin. It is a man-portable, shoulder-fired, low-altitude, infrared guided surface-to-air missile system (MANPADS) developed as a response to the limited performance of the earlier SA-7 Grail. The missile was largely based on the earlier Strela-2 and thus development proceeded rapidly. The most significant change over the Strela-2 was the introduction of an all-new infra-red homing seeker head. The new seeker worked on FM modulation (con-scan) principle, which is less vulnerable to jamming and decoy flares than the earlier AM (spin-scan) seekers, which were easily fooled by flares and even the most primitive infrared jammers. The new seeker also introduced detector element cooling in the form of a pressurized nitrogen bottle attached to the launcher. The effect of cooling was to expand the seeker's lead sulphide detector element's sensitivity range to longer wavelengths (slightly over 4 µm as opposed to 2.8 µm of uncooled PbS elements). In practice this made possible the tracking of cooler targets over longer ranges, and enabled forward-hemisphere engagement of jets under favourable circumstances. The seeker also had better tracking rate, enabling the missile to track maneuvering of fast and approaching targets. A negative side effect from the aforementioned improvements was increased missile weight, which caused a slight decrease in the kinematic performance compared with Strela-2M (SA-7B). Against relatively slow, low-altitude battlefield air threats the overall effectiveness was much improved. The new system was accepted into service in 1974. Strela-3 missiles have been exported to over 30 countries. ------------------------------------------------------------------------------------------ Known issues: - System has limited all aspect capability mostly against slow, low-altitude targets. - Helicopters have higher survival rate per hit because in some cases missiles hit the tail rotor without causing significant damage. I guess this is another game engine characteristic. - Low altitude (lower than 500 meters) performance is downgraded for current missile values. By increasing noise rejection the missile becomes capable of hitting targets in lower altitude but at the same time the single shot hit/kill probability is being increased to an unrealistic level. - Fuze distances are longer compared with the actual lethal and damage radius of the system. In SF2 world the real high explosive warhead quantity is big enough to destroy a fighter size target even in 10 meters! ---------------------------------------------------------------------------------------------- As always open readme.txt first to see installation instructions and credits.
