Hello Soldier35. There are several MANPAD Systems that may already be in Ukraine's arsenal. Two of them include:The problem is not in the air defense systems of Ukraine, but in a large number of MANPADS
1. The STARStreak-LMG-NG from Thales offered to the UK. It uses two, three or four either mounted or unmounted ready to fire missiles to engage multiple targets quickly. It employs TV & Thermal imaging cameras with manual or auto tracking modes for high-hit probability.
2. The RBS 70 NG (new generation) is a man-portable very short-range air defence (VSHORAD) system offered by Saab from Sweden. It is an improved variant of the RBS 70 system, which has been acquired by 19 countries worldwide. The modular design of the new VSHORAD is compatible with the current generations of RBS 70 missiles up to the latest fourth-generation missile BOLIDE. The 87kg MANPADS includes a missile in a launch container, a tripod firing stand, and an NG sight. It employs the new BOLIDE all-target VSHORAD missile equipped with a laser beam rider guidance system. The missile has a speed of 686m/s and can engage fixed and rotary wing aircraft, as well as cruise missiles and UAVs at altitudes up to 5,000m and ranges exceeding 9km. It offers a high hit probability and engages targets in clutter and countermeasures environments. The combined shaped-charge and pre-fragmented warhead carried by the missile further enables the system to defeat aerial and ground targets protected with armour.
