Reports emerged on Monday that the US is planning to send defensive weapons to Ukraine in order to deter Russia, which has managed and funded rebels in the Donbas.

The plan includes sending Javelin anti-tank missile systems, and possibly anti-aircraft and other weapons systems.

Developed by Raytheon in 1989, the FGM-148 Javelin is a large shoulder-mounted, infrared guided missile system capable of piercing 600mm to 800mm steel armor.

The Javelin is a medium-range missile system that fires up to 1.5 miles, weighs about 50 pounds, and costs about $126,000 — plus $78,000 for each missile.
