Protecting multi-hundred-million-dollar space vehicles from factory integration cleanrooms to launch pad payload processing facilities.
ISO Class 7/8 Cleanroom Vans
Sealed, stainless-lined van interiors equipped with continuous HEPA filtration units delivering laminar airflow, electrostatic discharge (ESD) grounded floors, and strict particulate management under ISO 14644-1.
Active GN2 Purge Blanketing
Onboard manifold cradles holding certified ultra-pure gaseous nitrogen bottles deliver a positive pressure blanket (0.25 to 0.75 PSI) to payload shipping containers, suppressing ambient humidity below 5% RH.
Tuned Wire-Rope Isolators
Multi-axis helical wire rope shock isolators tune the payload natural frequency below 8 Hz, preventing destructive coupling with semi-trailer chassis bending modes and fifth-wheel pitching resonances.
Classified Security Escort
DoD Secret cleared team drivers operating with non-stop satellite dual-custody tracking, constant secure comms with launch range safety officers, and civilian law enforcement or dedicated armed security escorts.

Frequently Asked Aerospace Transit Questions
How do Exspeedite telemetry hubs handle G-force excursion alerts in real time?
Our IoT gateways compute running RMS vibration and peak transient accelerations at 1,000 Hz. If any axis exceeds the 0.5G threshold for more than 10 milliseconds, an instantaneous LEO satellite packet is broadcast to both the escort driver tablet and client launch integration engineers with exact GPS coordinates and time-series waveform snapshots.
What happens if a nitrogen purge bottle depletes during transit?
Standard operating protocol mandates a primary and secondary manifold bank with an automated pneumatic changeover valve. An electronic pressure sensor triggers an audible and visual cab alarm when primary bottle pressure drops below 500 PSI, ensuring secondary supply engagement with over 48 hours of redundant buffer time.
What driver security clearances are required for National Security Space payloads?
All classified movements require two-person team drivers holding active DoD Secret or Top Secret clearances, verified TWIC credentials, and compliance with Military Surface Deployment and Distribution Command (SDDC) security escort standards.
