The Advanced Joint Effectiveness Model ( AJEM) is a lethality, vulnerability, and endgame computer simulation code capable of analyzing one or more threats attacking a single rotary-wing or fixed-wing aircraft, small watercraft, or ground-mobile system. It combines elements of target model viewing, threat modeling, encounter kinematics, generation of weapon burst points, propagation of damage mechanisms to the target, damage mechanism / target interaction (penetration, fire, blast, etc.), target system relationships (functionality, redundancies, etc.), and target remaining capability or loss of function.

AJEM was designed to be a U.S. Department of Defense (DoD) standard computer simulation for evaluating the lethality and terminal effectiveness of munitions and the vulnerability of aircraft, missiles, and ground-mobile systems, including battle damage assessment and repair (BDAR). AJEM produces results that are applicable during all phases of weapon system acquisition from research, design, and development to production test and evaluation. AJEM produces results which are observable/measurable for testing and real-world events.

AJEM is designed to run in conjunction with BRL-CAD® and the MUVES environment, capitalizing on work already performed by the Army Research Laboratory (ARL) Survivability/Lethality Analysis Division (SLAD).
