Rayhoven Air Base is an ISA military base which is located on the Southern Hills Nuclear ICBM stockpile.

Second Extrasolar WarEdit

Rayhoven Air Base is where the ISA made their final stand against Helghast General Joseph Lente's forces on Vekta. Due to the fact that a traitor within the Helghast's ranks, Colonel Hakha, had already warned the ISA of the Helghast's plan to assault Rayhoven, they fortified their defenses and were prepared for the Helghast attack. They drive the Helghast attack back, causing the first major victory for the ISA forces, boosting their morale greatly.
