Easier To Service
From a maintenance and repair standpoint, the EFV should be quite forgiving—an important consideration for a vehicle designed to operate in combat situations. "In the field, the EFV is designed to be much more modular than the AAV, allowing for Line Replaceable Units to be quickly swapped out once the on-board diagnostics systems have helped the maintainer to identify the problem," said Pacheco. He also pointed out that the EFV will take advantage of a Class 5 Interactive Electronic Technical Manual operating from a hardened laptop (portable maintenance device). The electronic manual will interact directly with the vehicle's diagnostic and health monitoring sensors to walk the troubleshooter through the process of quickly isolating and identifying one or more faulty components.
"The system has a requirement for maintainers to be able to swap out these modular components in an average time of 1.5 hours or less using standard Marine Corps tools, enabling vehicles to get repaired and back into the fight more quickly than their predecessors," Pacheco continued. After every six years or 900 hours of engine operation, the EFV will need to undergo a vehicle depot-level overhaul. A Condition-Based System Sustainment (CBSS) program, which is based on condition-based maintenance concepts, will provide proactive guidance to maintenance and repair personnel during overhaul periods. The AAV, by comparison, uses a reactive Inspect and Repair Only as Necessary depot maintenance program.
"A major advantage of CBSS is significantly reduced depot repair cycle times," said Pacheco. "By continuously collecting maintenance data being captured by vehicle health monitoring hardware/software such as embedded sensors and the Embedded Logistics Administration System, upgrades and repairs can be optimized to the specific condition of each vehicle."
During Tech Refresh/Insertion events conducted between depot periods in the field or in garrison, each EFV will receive a detailed technical inspection that includes removing the armor panels. Such inspections will provide yet another opportunity to observe any corrosion problems that may arise. "During Depot Refurbishment, each vehicle is stripped- down to the space frame where every inch can be inspected," added Pacheco. "Spare space frames will be pulled from inventory to expedite the refurbishment process and worn space frames will be restored off the repair line and returned to inventory."
Building On A Proud Legacy
Since Guadalcanal, the Marine Corps has repeatedly demonstrated its ability to successfully execute amphibious missions. The EFV will significantly enhance this capability by facilitating the delivery of combat power ashore rapidly from over the visible horizon, said Pacheco. He added that the vehicle embodies the Corps' flexibility in responding to new combat challenges.
"In the 21st century threat environment, the capability for the Navy-Marine Corps team to initiate ship-to-objective maneuver from distances far off shore that provide both force protection to the sea base and surprise for the landing force will be central to the EFV's legacy," Pacheco concluded. "Additionally, along with that amphibious mobility, the EFV's day and night lethality, enhanced survivability, and robust communications will all substantially improve joint force capabilities."
