There’s a race going on among tech firms — big and small — to join in the construction of what President Trump has dubbed the Golden Dome, a missile defense system similar to Israel’s Iron Dome. Tens of billions of dollars in military contracts are at stake. In fact, the total cost might be in the trillions and the project could stretch a decade.
