Iran’s space-launch capability: grounded?

International Institute for Strategic Studies | Joseph Dempsey

US and Israeli air strikes targeted two major Iranian space-launch facilities in Semnan province between March and April 2026, causing significant structural degradation to Tehran's dual-use space infrastructure. Satellite imagery confirms concentrated damage to the Imam Khomeini Space Centre's main launch complex, where the rail-mounted service structure for the liquid-fuelled Simorgh rocket sustained severe outer damage.

Fixed launch sites remain highly vulnerable to high-precision standoff munitions. The concurrent bombardment of the Islamic Revolutionary Guard Corps' Shahroud Space Centre destroyed over 40 solid-propellant production and assembly buildings across multiple strike packages. While mobile erector launchers grant the solid-fuel Ghased and Ghaem 100 platforms operational survivability from dispersed locations, the destruction of core manufacturing nodes curtails short-term replacement cycles. This systematic targeting directly impedes the Islamic Revolutionary Guard Corps from deploying additional space-based military reconnaissance assets while severely restricting the technological maturity of long-range multi-stage ballistic missiles.

Comment

Recurrent targeting of mixing and casting infrastructure at the Shahroud Space Centre exposes the industrial bottleneck of Iran's solid-propellant rocket motor manufacturing. Unlike liquid-fuelled architectures like the Simorgh, which rely heavily on fixed launch pads, solid-fuel systems depend on specialised chemical processing facilities for composite propellant grains. Repeated destruction of bermed assembly buildings fundamentally disrupts batch-production throughput for the Islamic Revolutionary Guard Corps.

Reconstitution of these specialised casting facilities requires high-precision planetary mixers and thermal curing chambers that Tehran cannot easily fabricate domestically. Without functional mixing infrastructure at Shahroud, payload expansion for multi-stage platforms like the Ghaem 100 stalls regardless of launcher mobility. The persistent destruction of planetary mixing equipment directly prevents the IRGC from sustaining serial production of heavy solid motors.

Strategic Question for Discussion

If dispersal via mobile erector launchers fails to offset the destruction of solid-propellant production infrastructure at the Shahroud Space Centre, which factor will dictate the timeline for restoring Iran's multi-stage rocket capability?

The available evidence points toward specialised equipment procurement as the primary pacing constraint rather than raw launch survivability. While mobile platforms like the Ghaem 100 allow tactical dispersion, replacing damaged high-capacity planetary mixers and propellant casting facilities at Shahroud requires foreign technology transfers that are vulnerable to interdiction. My assessment is that production bottlenecks will delay multi-stage solid-fuel motor integration long after physical launch sites are cleared.
