Force Protection – Occupant Centric Platform Technology Enabled Capabilities Demonstration (TECD)

New design philosophy that considers the Soldier first and builds the vehicle to

surround and support the Soldier and their mission.

• Reduce casualties by 50% across each mission role with scalable protection

levels to defeat a wide range of threats

• Enhance fielded mobility performance

• Maintain freedom of action during full spectrum operations.

Pre-conceptual

configuration

Occupant Centric Survivability

for Military Ground Vehicle

Design:

• Publish an overarching Military

Standard (MIL-STD)

• Publish technical specifications

• Update and develop component

and sub-system Test Operations

Procedures (TOPS/ITOPS)

Occupant Centric Concept

Demonstrator:

A physical realization of the new

Occupant Centric design

philosophy

Current Platform Demonstrator

A unique occupant protection

suite of technologies specific to

the platform given its design

constraints

Weight Reduction:

Weight neutral at threshold and

25% weight reduction at objective

Maneuverability and Mobility:

Maintain fielded mobility
