Unguided missile and projectile defense shield supported by tethered balloons

This invention describes a method to create a physical barrier in the sky to stop unguided missiles and other projectiles. It involves using a line of large balloons, tethered to the ground along a border, to suspend a defense shield. This shield would hang vertically to intercept and deflect incoming threats.

Why it matters: Advancements in lightweight, high-strength materials could make the physical shield more feasible and durable. The increasing prevalence of low-cost unguided threats makes a passive barrier more relevant.

Status: ExpiredProtection ended and was never renewed
How hard to build: SpecializedLarge balloons, robust shield, weather resistance, deployment logistics.
