Iran may have developed a new design of hardened launch site, possibly the first intended specifically for solid-fuel ballistic missiles.

Although Tehran has in recent years showcased several underground complexes (sometimes dubbed ‘missile cities’) – complete with cavernous launch silos – they have not included the Haji Abad structures.
