ONR ST Efforts in Support of JLTV
2
Background

• In the summer of 2005 the Army USMC emphasized
  the need to replace the HMWWV
• This new program is called JLTV
• Milestone B was originally scheduled for spring
  of 2007
• This left 18 months to conduct science and
  technology (ST) efforts to meet these aggressive
  timelines

ONR ST Support to JLTV

• ONR quickly initiated the Combat Science
  Technology Vehicle (CSTV) program which consisted
  of many activities
• The Chief of Naval Research (CNR) allocated 8
  M for FY06/FY07
• USMC 6.2/6.3 funding added 6 M for FY06/FY07
• Collaborated with TARDEC
• The purpose of this brief is to share the results
  and lessons learned from some of these efforts
  for you to consider as you develop your proposals

Agenda

• BAA Concept Studies Results
• Fuel Efficiency Studies
• Ship Transportability Study

5
ONR BAA Concept Study

• Scope of Effort Objectives
• Develop JLTV concept designs based on notional
  set of performance requirements as expressed in
  RFI dated 22 Dec. 2006
• Incorporate an open architecture to accommodate
  technology insertions opportunities in 2012 and
  beyond
• Develop notional designs for a family of vehicles
  from Gap 1 through Gap 5
• Consider modular / common design, that addresses
  threshold and objective RFI criteria
• Provide cost estimate for 20,000 of each
• Provide a mock-up of the combat tactical vehicle

ONR BAA Results of Studies - Survivability

• ONR provided a specific ONR ST Integral Armor
  Threat
• Purposely tougher than the JLTV RFI to challenge
  contractor designs
• Vast majority of BAA concepts are at or under the
  Essential Combat Capability transport weight,
  while meeting the ONR ST Integral Armor
  survivability level

ONR BAA Results of Studies Transportability
Commonality
Transportability

• Commonality
• Most BAA concepts met Commonality index threshold
• Long Range Surveillance (LRS) and Ground Mobility
  Vehicle (GMV) are lowest in commonality due to
  variation in body size, not necessarily
  components (original gaps 1 and 5)

ONR BAA Studies Summary

• Survivability
• Vast majority can meet ONR ST Threat
• Mobility Performance
• Predominance of RFI requirements can be met
• Transportability height / weight
• Vast majority can meet all RFI requirements
• Commonality of components systems
• Predominance are in 90-95 range

Fuel Efficiency Studies
11
Fuel Efficiency Studies

• ONR participating in ARMY HEVEA (Hybrid Electric
  Vehicle Experimentation and Analysis) ATO (Army
  Technical Objective) by funding
• The development of VPSET Modeling Simulation
  capability
• VPSET will assess candidate drivetrain design
  configurations
• Supporting Military Drive Cycle analysis by ATC
• Survey will develop operating profiles for
  vehicle missions role variant
• Survey of fuel efficiency enabling technologies
  by SwRI
• All three together will be used to assess
  notional drivetrain design efficiencies /
  capabilities over varying mission profiles.

Ship Transportability Study
13
Ship Transportability Study

• Accomplishment
• Obtained MSC ship characteristics
• Obtained Navy ship Landing Craft
  characteristics
• Developed notional JLTV vehicle reference
• Studied ramp Kick-up and Break-up requirement
• Included inputs and comments from PrePosioning
  Branch, Seabasing Integration Division, MCCDC

• Objective
• To identify operational and interface limits in
  applicable ships (Navy, MPF, MSC, and Commercial)
  and aircraft that will transport the JLTV.

14
Overall Findings

• BAA studies show a JLTV can be designed that
  meets the RFI within weight and space claims for
  transportability
