He noted that threats to vehicles include kinetic energy from bullets (small arms, medium cannon, and large caliber rounds) , chemical energy from shape charge jets and explosively formed projectiles, and underbody threats from mines and improvised explosive devices.

Designers also looked at structural design, such as vibration mounting, dynamics, and damage control. Over the past several decades, Carter explained, this research has advanced to include composite-laminate and encapsulated ceramic materials and changes in structural design to confine damage.

They are investigating direct material replacement and the secondary weight savings with new materials. However, based on the desired performance and the time frame with which to achieve the reduced vehicle weight, Carter stated that the consensus within the scientific community is that additional solutions for weight reduction will have to be applied.

From page 6... ...
Carter provided examples such as using automation to reduce the number of crew required, apply ing weight optimization to component designs, and applying technologies such as Adaptive Armor and Active Protection Systems. Materials science solutions can then be integrated with these technology solutions to achieve the weight reduction and performance desired from the vehicle system.

-- Continue to invest in efforts to consolidate vehicle architecture -- Metals/semiconductors -- carbon nanotubes, graphene, SiC The campaign also produced the following overarching recommendations: • Organizational recommendations -- Utilize an existing Army-wide governing body with a board of directors (BoD) to ensure purposeful focus on light-weighting Army combat vehicles -- he BoD and cross-organizational team will publish light-weight T ing metrics/requirements for research, development and acquisition programs -- ncentivize Program Management Offices to encourage lightweight I technology insertion on future and currently fielded platforms • Design recommendations -- ontinue investment in programs like Materials in Extreme Dynamic C Environments (MEDE)

Thus, a future infantry fighting vehicle design with similar capabilities will have to over come similar subsystem weight challenges. Carter and Polsen also noted that the enemy is much faster at changing tactics than the military is at fielding new vehicles -- the enemy is "inside the development cycle," to use a common military term.
