K -- REPLACEMENT TO AN/TPS-59(V)3 RADAR MAINTENANCE LIFT DUE 022900 POC Contracting Officer Leigh D'Lugos E-MAIL: Click here to contact the contracting officer, dlugossl@mcsc.usmc.mil. MARKET RESEARCH. NO SOLICITATION EXISTS AT THIS TIME. The Marine Corps Systems Command (MCSC), Program Manager Air Defense (PMAD)is interested in obtaining information from industry regarding a replacement to the AN/TPS-59(V)3 Radar Maintenance Lift. MCSC is considering the fielding of a form/fit/function replacement to the Maintenance Lift subsystem of the Marine Corps' long range air surveillance radar AN/TPS-59(V)3, manufactured by Lockheed-Martin Ocean, Radar & Sensor Systems of Syracuse, NY. It is the Marine Corps'expectation that the replacement to the Maintenance Lift will be entirely composed of commercial-off-the-shelf (COTS) hardware. The Maintenance Lift provides service access to all major components of the antenna array while the array is in its erected vertical configuration. Standard operating procedures of the Marine radar crew involve regular (multiple times daily) use of the lift by two Marines with up to 200 pounds of equipment in the performance of routine and emergency maintenance and repair at points along the entire length of the antenna array. The Maintenance Lift currently consists of a man-rated platform traveling the vertical length of the antenna array along track-punched rails by way of electrical motor and drive sprockets. The lift also includes clutched emergency brakes attached to secondary sprockets. Requirements for the form/fit/function replacement to the Maintenance Lift include a maximum vertical travel of 30 feet, a live load capacity of 600 pounds, a configuration which accommodates the disassembly and transport clearance requirements of the overall array system, a total Maintenance Lift subsystem weight of under 750 pounds, a motorized motion allowing stopping at any point along the vertical travel, power supply requirements not exceeding that available on the array (120/208V AC 400Hz), and little to no alteration of the existing antenna array structure. Any components of the Maintenance Lift which must disassemble to accommodate the transport configuration of the antenna array must be designed to fit in standard military transit cases and must be integrated into the overall stowage configuration of the array group. The hardware of the Maintenance Lift must be operational and maintainable in all types of climates and terrains where Marine Air Control units deploy. The Maintenance Lift must be capable of operating in 40 to +55 degrees Celsius environmental conditions, in air pressure equivalent to 1000 feet below sea level to +40,000 feet above sea level, and being stored and transported in ambient temperatures of -40 to +68 degrees Celsius; it must operate in salt laden air and spray normally encountered in Marine amphibious operations without suffering corrosion or damage that would render the system incapable of performing its mission. The Maintenance Lift must be supported within the existing USMC's three-level maintenance concept (organizational, intermediate, and depot) using common tools and general purpose test equipment. The Maintenance Lift must have a MeanTime Between Operational Mission Failure (MTBOMF) of at least 120 hours and an operational availability of at least 98 percent. Maintenance Lift preventative maintenance (PM) shall only be required weekly; Mean Time to Perform PM at the organizational level will be one hour or less. Interested firms capable of meeting the aforementioned minimal Maintenance Lift mechanical requirements are invited to submit the above information in three (3) copies not to exceed thirty (30) pages. THIS IS NOT A REQUEST FOR PROPOSAL, NOR WILL THE GOVERNMENT PAY FOR ANY INFORMATION SOLICITED. Acknowledgement of receipt will not be made. Proprietary data will be protected when so designated. Firms should include in their response whether or not they are a small or small disadvantaged business. Posted 12/22/99 (W-SN410854). (0356)
