TRAPS (Tactical Rocket-Propelled Grenade (RPG) Airbag Protection System) is an active vehicle protection system incorporating Textron Defense Systems' sensors, which are configured to identify incoming RPGs. Once the sensors confirm an RPG threat, a TRAPS countermeasure is deployed to defeat the RPG and prevent vehicle penetration. Lightweight and constructed of commercial, off-the-shelf components, TRAPS is integrated easily onto any ground vehicle, wheeled or tracked, within the vehicle's existing profile.

TRAPS is designed for use for the protection of light and medium protected vehicles. The system employs a sensor detection technology combined with airbags and non-lethal countermeasures to defeat threats.“Goals for this round of testing included recording extensive system data, as well as evaluating its baseline operational performance,” says Chief Technology Officer Tom McNamara of Textron Systems Corporation.

TARPS was created as the 'inflating airbag system' (IAB) developed by a company named IST, which developed a prototype that combined an inexpensive radar sensor and airbag systems which are inflated before the RPG hits the protected vehicle. The airbag disrupts the shaped charge fuse, as the projectile collapses upon itself, jamming the time-out fuse, thus defusing the shaped charge before it hits the vehicle's skin. During the initial tests, the system was installed on up-armored Humvees doors, and demonstrated effective protection of the crew compartment. IABS was also effective in protecting the transparent armor (windows) which were broken, but were not penetrated by the RPG.
