Pentagon testers: JLTV hinders marine amphibious assault operations - IHS Jane's 360: Pentagon testers have found that Joint Light Tactical Vehicle (JLTV) prototypes are slow to deploy from ship to shore and, therefore, leaves US Marine Corps (USMC) units "vulnerable to threats".
The Director of Operational Test and Evaluation annual report on the previous year's testing, released on 20 January, found that during developmental test/operational test (DT/OT) events, USMC units with JLTVs were able to execute amphibious assault missions, but were hampered by the new trucks' lack of deployability.
"The JLTVs have large visual signature and their slow manoeuvre time from ship to shore prevents a Marine Expeditionary Unit from executing assault missions with tactical surprise, increases the time to close combat power ashore, and renders the unit vulnerable to threats," the report said.
"Testing showed that JLTVs are slower to load, prepare for fording, and transition to manoeuvre ashore than HMMWV [Humvees]" that they are meant to replace, the document said. Testers explained that the issues were caused by the JLTV's overall larger size (vehicle suspensions are dropped so they can better fit in amphibious ships) and "delays that occur while awaiting suspension mode, and other vehicle adjustments" such as adjusting tyre pressure.
A spokesman for the Army Program Executive Office for Combat Support & Combat Service Support declined to comment on whether the office has developed a plan to address deficiencies outlined in the report.
