Unlike the AGM-86C, this cruise missile carries two rocket boosters in addition to its internal engine, meaning the RBS-15 can be launched from a stationary vessel. The boosters automatically detach when their fuel is expended. The rocket boosters make the RBS-15 more suitable to ground-based launch systems.
It has the same slider options in the SPH as other missiles, but you can also set its cruise altitude – from 30 to 2500 meters. This capability gives the RBS-15 the ability to strike targets at different altitudes or from different attack angles depending on the user's settings.
