12 -- MODIFY GUN CONTROL ASSEMBLIES FOR USE ON THE M109A6 PALADIN 15 5MM SPH SOL DAAE30-95-R-0050 DUE 052295 POC Major John Thiel, email=jthiel, Contract Specialist, 201-724-2920, Gregory L. Gorman, email=ggorman, Contracting Officer, 201-724-3271. The U.S. Army ARDEC requires modification of the M109A2/A3 gun control assemblies for use on the M109A6 Paladin 155mm Self-Propelled howitzer. The M109A2/A3 gun control assemblies operate at a hydraulic pressure of 925 to 1200 PSI and the modified assemblies for the M109A6 operate 1925 PSI. Based upon the Government furnishing approximately 1028 used M109A2/A3 gun control assemblies to the contractor, the contractor shall overhaul the used assemblies per DMWR-9-2350-311-2 (1 Nov 90) and modify all of the assemblies per the approved Government engineering change proposal P0034, test, package and ship them to the schedule. The schedule for the completion of the 1028 assemblies is as follows: Basic Qty 198 each 1994, plus option qty 430 each 1995, and option qty 400 each 1996. Specific testing requirements: A. Testing of modified control assemblies will require a hydraulic test bench capable of MIL-STD-1246 level 200 hydraulic cleanliness and delivering MIL-H-6083 hydraulic fluid at 2000 PSI, 15 GPM. Associated pressure and flow measurement devices will be required. The respondent must also be able to measure the angular displacement of the control handle to an accuracy of plus or minus .5 degrees. B. Testing of the modified spool and sleeve assemblies will require the fabrication of a suitable test body and the use of centering device to establish spool displacement. These test equipment requirements are in addition to the equipment requirement in A above. Site inspections may be necessary. The Government will restrict the number of contractors eligible for award to those contractors approved on the Qualified Manufacturing List (QML). Both a successful bench test and a Government conducted system test will be required in order for a contractor to become qualified to modify the M109A2/A3 assemblies. The Government point of contact for this effort is Major John Thiel, 201-724-2920 (0109)
