Mine and Obstacle Breaching S&T Strategy
Spiral Development Approach• JDAM Assault Breaching System (JABS): Precision guided
bombs for surface laid BZ/SZ mines and obstacles• Advanced Warhead Development: Countermine darts with
greater kill radius & effectiveness against buried BZ/SZ mines• JDAM Assault Breaching System (JABS): Extend BZ/SZ
capability to neutralization of VSW Mines
Develop a Precision Breaching Capability• Key enablers include ISR, Weapon Precision Guidance, and
Precision Navigation• Delivery by Naval TACAIR, USAF Bombers

• Offers potential to detect buried targets in wet and dry sand environment
• System combines an acoustic source to excite the target and the surrounding area with a laser-based electro-optic imaging technique
• Measures the differences in the mechanical response of the ground directly above a buried target with that of the surrounding area.
