155mm Linear Variable Displacement Transducers Equipment

The contract requires the development and delivery of specialized equipment for calibrating and deploying sensors within 155mm artillery systems, specifically the M284 and M776 gun tubes. The 155mm Calibration Guide Tube Assembly must permit the removal of the calibration ring while remaining affixed to the cannon muzzle, enabling in-place calibration without disassembly. It must also support the secure positioning of the crawler, LBIS, and LVDT sensors while accommodating the physical dimensions and operational requirements of the 155mm bore. Additionally, the 155mm Self-Propelled Sensor Delivery Unit must be capable of precisely moving 120mm sensors over a minimum axial distance of 35 feet, either pushing or pulling, and must interface seamlessly with existing YPG-owned LBIS, LVDT, and VBIS sensor systems. The SDU must include a muzzle adapter compatible with 155mm gun tubes and a flexible cable with a non-scratch protective cover to prevent damage to the bore. It must enable full-bore data acquisition up to the muzzle with a linear resolution of 0.010 inches or better and achieve uni-directional position repeatability of 0.040 inches or better. The solicitation, identified as W911S226U3368 and titled 155mm Linear Variable Displacement Transducers Equipment, was posted on June 25, 2026, with a response deadline of July 2, 2026. It is a combined solicitation under a Total Small Business Set-Aside, classified under NAICS code 334519, and managed by the Department of Defense through the Office at Fort Drum, New York.
