Script Details
Rapid deployment of the Future Force will require in-theater airfields to sustain intense aircraft operations. In many force projection operations, in-theater airfields will be undersized, understrength, or severely deteriorated. Our currently military engineer and construction units do not have the capability to rapidly upgrade existing or construct contingency airfields to support Future Force mission requirements.
The US Army Engineer Research & Development Center is the spearhead of a new initiative called “Joint Rapid Airfield Construction” or JRAC. This program is identifying innovative technologies and developing rigorous solutions to allow our military to deploy virtually anytime and anywhere. JRAC enables battlespace dominance through rapid force insertion and freedom of maneuver.
Our mission is to provide an airfield with sufficient throughput capacity to insert a Unit of Action into the active theater. Optimal airfield site will meet tactical, force protection, lines of communication, and operational requirements. Once the airfield site is selected, it must be operational within 48 hours.
From remote reconnaissance and analysis of theater databases, potential landing zones have been identified, but critical state-of-ground data that includes topographic and soil strength information are needed before a final decision an airfield site can be made.
This critical state-of-ground information is collected by the “RAVEN”. The RAVEN, or Rapid Assessment Vehicle Engineer, is a manned or unmanned ground vehicle used for initial remote unmanned site assessments, rapid soils analyses, construction quality control, and multi-purpose construction assistance. The RAVEN’s state-of-the-art technologies include topographic laser, global positioning systems, on-board computer, satellite reach-back technology, 360-degree video camera, soil identification equipment, and a dynamic cone penetrometer.
The RAVEN can be dropped into the potential site and autonomously controlled from the tactical control center. Using the on board tools, field data are collected remotely and sent anywhere in the world for instant access by engineers and war planners. These data are then analyzed with simple decision aid software systems to select one or more airfield sites based on engineering principles before committing troops, equipment, and material to the theater. If necessary the RAVEN then can be tasked for further testing for a complete reconnaissance of the overall site conditions. The JRAC site selection process will tell us what the engineering challenges are before we get there.
Once it is determined that the suitability of this site meets the mission parameters. The go ahead is given for the first wave of construction equipment to be delivered to the area. Aircraft operations begin delivery of the necessary construction equipment for the earthmoving portion of the apron construction. This portion of the project should be completed in 12 hours, day or night.
As the earth-moving phase begins, simultaneously, engineers are now in the RAVEN performing more advanced soil testing to determine the exact stabilization requirements once the site is properly leveled and graded. This information is immediately used to determine the proper stabilization requirements for the given site and available materials.
New expedient methods for construction incorporate GPS technology to provide survey grade control or the earth moving equipment during airfield construction projects. Equipment operators are fed the cut and fill requirements in real time through a computer interface, with the data being sent digitally to both the tactical operations center as well as to other similarly equipped machines on the project site. These new state-of-the-art construction methodologies will greatly decrease the time required for pre-construction efforts, basically eliminating the need for traditional surveying techniques such as ground staking. Other advantages include: significant manpower reductions, increased accuracy, and stealthy night operations.
With the completion of the earth-moving phase, engineers are now ready to begin the soil stabilization process. Low-dosage, rapid-curing soil stabilizers are applied to the construction zone, and a soil pulvermixer follows to incorporate the stabilizer into the soil. Following the pulvermixer, the compactor performs the final steps in the soil stabilization process. JRAC soil stabilizers provide rapid curing capabilities that allow us to reach sufficient contingency airfield soil strengths within hours instead of days or weeks.
Within 48 hours, a single JRAC engineering unit has improved an existing airfield site from a maximum-on-ground rating of one to three. With minimum manpower, equipment, and materials, we have tripled the value of this airfield and created a valuable asset for force deployment and maneuver.
Mission Accomplished.
