""To handle such a wide range of targets RAFAEL offers the missile with a choice of two warheads – an anti-tank missile optimized with an enhanced tandem warhead that increases armor penetration by 30 percent over the previous generation. Another advantage of the new missile is its ability to strike at higher impact angles – Spike LR II will be able to hit targets at up to 70 degrees, delivering more lethal top attack profile. According to RAFAEL, the SPIKE LR II is the only missiles known to have an inherent Counter-APS (CAPS) capability.""
""Those software-based AI functions enable the seeker to maintain target lock even in situations that auto trackers generally fail – target disappearing behind obstacles, or against a low-contrast background, where third generation (fire and forget) missiles would fail, and fourth generation missiles would need operator assistance. The new Spike LR II can overcome such challenges and track its target automatically. Moreover, as a software defined feature those seeker functions can be changed and upgraded, enabling designers to implement innovative techniques against new enemy counter-countermeasures.""
